(n=21, 5.3%), calcic constrictive pericarditis (n=4, 10.6%), recurrent constric­tive pericarditis after partial pericardiectomy (n=9, 2.3%), and postsurgical con­strictive pericarditis (n=9, 2.3%). Three hundred and twenty-eight (83%) patients underwent total pericardiectomy via median sternotomy, and 57 (14.4%) patients underwent partial pericardiectomy via left anterolateral thoracotomy. Cardiopulmonary bypass was used in 7 (1.8%) cases because of perforation and massive bleeding from the inferior cavoatrial junction, and pulmonary artery [16].
Operative and late mortalities were 7.6% and 4.9% respectively. At a mean fol­low- up of 17.9±0.3years (95% CI: 17.3–18.6), actuarial survival was 83.8%±0.04% in the total pericardiectomy group and 73.9±0.06% in the partial pericardiectomy group (log rank, p=0.004). At 17years, 96.3% survivors of total pericardiectomy and 79.1% survivors of partial pericardiectomy were in NewYork Heart Association I/II (p<0.001) [16].
Diastolic lling parameters remained abnormal in 54 (15.9%) of the total peri­cardiectomy and 35 (61.4%) of the partial pericardiectomy group in the immediate postoperative period (p<0.001). At closing interval, 11 (3.7%) and 9 (20.9%) of the respective groups continued to have abnormal diastolic lling pattern on Doppler echocardiogram (p=0.004) [16].
This investigation concluded that total pericardiectomy is associated with lower perioperative and late mortality, and confers signicant long-term advantage by pro­viding superior haemodynamics that appear to be independent of the aetiology of constrictive pericarditis [16].
Joseph Rubin while commenting on the above article goes on to write, “…in this
study, median sternotomy provided good exposure of the right atrium and the venae cavae and enabled excellent clearance of the diseased pericardium. This approach demonstrated enhanced safety, decreased mortality, less postoperative low output syndrome, abbreviated hospitalization, and better long-term survival (log-rank, p=0.0001) than that obtained via thoracotomy. In the event of inadvertent excessive bleeding (n=7), the patient could easily be connected to cardiopulmonary bypass…” The unstated conclusion is that the maximum benet for constrictive pericarditis, in particular, is expected from total pericardiectomy, which is best achieved through a median sternotomy and is very difcult if not impossible through a left anterior thoracotomy.
Such is the stuff that allows rm conclusions. Chowdhury and colleagues have the data that are supported by excellent statistical comparisons of the two approaches. They can assert that median sternotomy is the approach of choice for chronic constrictive pericarditis, calcic patches, and pericardial masses. They dis­pel the controversy to which they alluded about the choice of approach for constric­tive disease. Also, they can state that left anterolateral thoracotomy should be reserved for the surgery of pyogenic and effusive pericardial disease.” [16].
Despite total pericardiectomy, the operative mortality rate was 7.6% in our series and 6–19% in several large series published after 1985 [1619, 24, 25, 3033, 39,
40, 44, 59, 60, 64, 67, 83, 9193, 108], Unlike others, there was no correlation with
age, tuberculous aetiology, and advanced NYHA symptoms on late survival, pre­sumably because of the young patient population and timely institution of

chemotherapy and surgery [1619, 24, 25, 3034, 39, 40, 44, 59, 60, 64, 6769, 77,
83, 9193, 108],
Although median sternotomy approach allowed a more radical clearance of peri­cardium overlying the right atrium and cavo-atrial junctions. Furthermore, it is impossible to excise the portion of pericardium posterior to the phrenic nerve using this approach [1619, 24, 25, 3034, 39, 40, 44, 59, 60, 63, 64, 67, 68, 83, 91
93, 108].
Part B: In an effort to decrease the perioperative mortality rates and postopera­tive low cardiac output syndrome, the author proceeded to perform several technical modications of the conventional left anterolateral thoracotomy approach to achieve further radical excision of the pericardium posterior to phrenic nerve and diaphrag­matic pericardium without utilizing cardiopulmonary bypass [17, 18, 2532].
The step-by-step technical details of median sternotomy (n=55) and the author’s modication of left anterolateral thoracotomy (n=67) to achieve radical pericardi­ectomy without utilizing cardiopulmonary bypass have been alluded to in our previ­ous publications and has been addressed in Chaps. 13, 14, 15, 17, 22, 23, 24, and 25 [17, 18, 2530].
Part C: In a subsequent investigation by Chowdhury UK and colleagues, a series of 127 consecutive patients (91 being male patients) aged between 4 and 72years (median, 25 years; interquartile range, 18–38) underwent total pericardiectomy using a modied left anterolateral thoracotomy without cardiopulmonary bypass between 2005 and 2019 [25].
The authors sought to ascertain the short- and long-term results of total pericar­diectomy for chronic constrictive pericarditis using a modied left anterolateral tho­racotomy without cardiopulmonary bypass (UKC’s modication) on postoperative low cardiac output, survival, and re-operations.
Patients with annular constrictive pericarditis (n=11), calcic pericardial patch compressing predominantly the right atrium and right ventricular outow tract (n=17), circumferential “cocoon” calcication encompassing all cardiac chambers (n=9), calcic spurs penetrating the ventricular chambers (n=18), recurrent peri­carditis after previous partial pericardiectomy (n=5), constrictive pericarditis after mediastinal irradiation (n=4), extracardiac intrapericardial mass (n=5), previous open heart surgery (n=3), and a gradient between the superior and inferior cavoatrial junctions more than 2mm Hg (n=3) were preferably considered for median ster­notomy approach and were considered contraindications for this approach. Median sternotomy was preferred in this subset of patients for improved surgical exposure and easy institution of cardiopulmonary bypass, if required for inadvertent cardiac injury and bleeding.
By employing these modications, radical pericardiectomy was associated with further reduction of hospital mortality from 7.6 to 2.9% (total pericardiectomy) and reduction of postoperative low cardiac output syndrome from 69% (total pericardi­ectomy) to 26.8% (radical pericardiectomy) [1619, 24, 25].
Part D: Among patients with low cardiac output syndrome following pericardi­ectomy, two male patients aged 18 and 19years respectively undergoing total peri­cardiectomy for chronic calcic constrictive pericarditis developed systemic

ventricular failure unresponsive to medical management following surgery. The failing circulation was successfully supported using intra-aortic balloon counterpul­sation. The authors concluded that aortic counterpulsation facilitates recovery of ventricular function and appears to be a reasonable alternative in select instances of refractory cardiac failure following pericardiectomy [34].
Subsequent to the publication on the use of intra-aortic balloon counterpulsation following pericardiectomy, 17 more patients were supported with intra-aortic bal­loon counterpulsation for failing postoperative hemodynamics with successful out­come (unpublished).
Part E: In a subsequent investigation, these investigators from All India Institute of Medical Sciences prospectively evaluated the changes in Tissue Doppler Imaging (TDI) at mitral and tricuspid annuli in patients undergoing pericardiectomy for chronic constrictive pericarditis and identied the relationship (if any) of the TDI­derived variables with the patient’s symptomatic status following surgery [35].
Fifty-four patients aged 7years to 70years (mean 31.0±16.8years) undergoing pericardiectomy via median sternotomy for constrictive pericarditis were studied for 24.4±10.8months (range 6–42months). They underwent Doppler ow velocity and TDI studies. A generalized estimating equation was used to test the changes in TDI-derived mitral and tricuspid annular velocities in postoperative period from the baseline.
Despite congestive cardiac failure, all patients had normal left ventricular ejec­tion fraction and increased medial mitral and tricuspid early diastolic septal velocity (e) with “annulus reversus”. This pattern of annular velocity improved maximally in the immediate postoperative period. At closing interval, 10 (18.5%) patients con­tinued to be in NewYork Heart Association class II; 9 of them continued to remain in atrial brillation. There were no differences of TDI-derived systolic and diastolic annular velocities of the mitral and tricuspid valves in the preoperative period between symptomatic and asymptomatic patients.
The investigators concluded that preoperative atrial brillation is a predictor of poor prognostic outcome following pericardiectomy. Tissue Doppler Imaging­derived mitral and tricuspid annular velocities were non-predictors of postoperative outcome following pericardiectomy. Tissue Doppler Imaging is a useful investiga­tive modality for diagnosis of constrictive pericarditis; it is not a useful indicator for postoperative evaluation [35].
Sankhyan LK and associates from All India Institute of Medical Sciences, New Delhi evaluated twelve patients aged 7 years to 70 years (median 21; IQR:
19.75–26.5 years), undergoing pericardiectomy for constrictive pericarditis were studied for 2–36months (median 19months). They underwent Doppler ow veloc­ity, tissue Doppler imaging, and two-dimensional speckle echocardiographic stud­ies [91].
The objective(s) of this study was to prospectively evaluate the changes in Tissue Doppler Imaging (TDI) at mitral and tricuspid annuli, and two-dimensional speckle tracking echocardiography in patients undergoing pericardiectomy for chronic con­strictive pericarditis and identify the relationship (if any) of the TDI and speckle

echocardiographic derived variables with the patient’s symptomatic status follow­ing surgery.
There was signicant statistical improvement in the Global circumferential strain rather than in global longitudinal and global radial strain after pericardiectomy. These investigators concluded that Tissue Doppler Imaging and speckle tracking echocardiography are useful investigative modalities for serial evaluation of patients undergoing pericardiectomy. It can be performed serially with a high degree of reproducibility [91].

21.15 Japanese Nationwide Outcome Study
Tokuda Y and associates evaluated the current results and the predictors of periop­erative complications for pericardiectomy for constrictive pericarditis in Japan. A total of 346 patients who underwent isolated pericardiectomy for constrictive peri­carditis nationwide between 2008 and 2012 were identied from the Japan Adult Cardiovascular Surgery Database which captured clinical data from 456 Japanese hospitals [93].
The mean age was 65.7±11.7years, median 68.0years. Pericardiectomy was performed using cardiopulmonary bypass in 100 (28.9%) patients. The approach was through a median sternotomy in 311 (90%) patients, and through a left antero­lateral thoracotomy in the remaining 35 (10%) patients. Perioperative mortality rate was 10.0%, and the composite operative mortality or major morbidity (stroke, re­operation for bleeding, need for mechanical ventilation for more than 24hours post­operatively due to respiratory failure, renal failure requiring dialysis or mediastinitis) was 15.0%. Cardiopulmonary bypass was used in 2.9% patients of the thoracotomy group and, 31.8% of the sternotomy group (P<0.0001) [93].
These investigators concluded that pericardiectomy is associated with high mor­bidity and mortality rates. Careful consideration should be given to these risk fac­tors in the process of patient selection and perioperative management.
21.16 German Series
In 2001, Omoto T and associates analysed their experience on 79 patients undergo­ing pericardiectomy for chronic constrictive pericarditis between 1985 and 1999 at the German Heart Centre, North-Rhine-Westphalia, Germany. The median age was
56.6±2.5years, range 22 to 77years [72].
It is noteworthy that the subtotal and partial pericardiectomy were dened vari­ably in their series. The extent of pericardial resection that had been termed ‘subto­tal pericardiectomy’ by the investigators would now be called ‘total pericardiectomy’. Most operations (77) were carried out using cardiopulmonary bypass, with subtotal pericardiectomy in 75 patients. Perioperative cardiac-related mortality was 5%.

During a mean follow-up of 47.52± 35.4 months, there were 15 (20%) deaths. Improved functional capacity was recorded in 66/75 (88%) patients; 60 (80%) patients were in NYHA I or II postoperatively. Actuarial survival rate at 1, 5 and 10years was 89.9 ± 3.4%, 74.9± 5.7%, and 55.4± 13.5% respectively. Female gender, valvular heart disease, renal insufciency, concomitant coronary artery bypass grafting and valvular heart surgery, preoperative ventricular end-diastolic pressure>20mmHg were signicant negative predictors of long-term survival [72].
The aetiology of the pericardial disease was tuberculosis in 4, radiation induced in 5, previous cardiac operation in 13, previous incomplete pericardiectomy in 4, and unclear in 52 (66%) patients. These authors recommended routine cardiopul­monary bypass for performing pericardiectomy in all cases.

21.17 Emory University, Atlanta, Georgia, USA
Miller JI and associates in 1981 reviewed their experience on 102 patients undergo­ing pericardiectomy between 1974 and 1980. The mean age was 5.8years (range 16 to 84years). The aetiology of chronic constrictive pericarditis was neoplastic (26), uremic (21), post open-heart surgery (19), idiopathic (17), and tuberculosis (8). The surgical approach was median sternotomy in 26 patients, left anterolateral thora­cotomy in 72 patients, and subxiphoid approach in 4 patients. Only 2 patients required cardiopulmonary bypass. Perioperative mortality was 8.8% [64].
These investigators concluded that, from a technical standpoint, all cases of pre­dominant effusive-constrictive pericarditis should be approached through a left anterolateral thoracotomy; all cases of constrictive pericarditis should be approached through a median sternotomy with standby cardiopulmonary bypass; and a subxi­phoid approach should the reserved for those patients too ill for the above or for pericardial biopsy and pericardial drainage. Betadine should probably be avoided for irrigation of the pericardial sac.
21.18 The Johns Hopkins Medical Institution, Baltimore,
Maryland, USA
In 2012 Timothy George and co-investigators evaluated their experience and attempted to dene the impact of aetiology on outcomes in a cohort of 98 adult patients undergoing pericardiectomy between 1995 and 2010 [40].
The mean age of the cohort was 50± 16 years. The most common aetiologies were idiopathic (n=44), postoperative (n=30), and post-irradiation (n=17). Total pericardiectomy was performed in 94 patients through a sternotomy (n=93), left anterolateral thoracotomy (6), and bilateral thoracotomy in 2 patients. Thirty-three

patients underwent redo sternotomy. Of 34 requiring cardiopulmonary bypass, 27 patients (79.2%) had concomitant cardiac anomalies [40].
At a median follow up of 4.0 (IQR: 1.3–7.4) years, there were 42 (42.7%) deaths Overall, 1, 5, and 10years’ survival were 82.5%, 64.3% and 49.2% respectively. Survival differed sharply by aetiology with idiopathic, post-operative, and post­irradiation 5-year survivals of 79.8%, 55.9% and 11% respectively (p<0.0001). On Cox regression analysis, only the need for cardiopulmonary bypass (hazard ratio [HR]: 21.2, p<0.02) was predictive of 30-day mortality, while post-radiation aeti­ology (HR: 3.19, p<0.02) and hypoalbuminemia (HR: 0.57, p<0.03) were associ­ated with increased 10-year mortality [40].
These authors concluded that post-radiation pericarditis, hypoalbuminemia, and hyperbilirubinemia are signicant risk factors for decreased long-term survival. Secondly, while the aetiologic spectrum has changed over time, these changes have not affected outcomes [40].

21.19 US Nationwide Outcomes Study
Following Pericardiectomy
In 2013, Gopaldas RR and associates published a US nationwide inpatient- outcomes study on 13,593 patients who underwent pericardiectomy between 1998 and 2008. Pericardiectomy was performed for constrictive pericarditis (28%, n=3851), peri­cardial calcication (15%, n=2061), secondary malignancies (3%, n=456), adhe­sive pericarditis (2%, n=318), and other causes (40%, n=5461). Only 62% were routinely discharged home [46].
They demonstrated that pericardiectomy was associated with a mortality of
7.5%. Cardiopulmonary bypass was required in 9.3% of cases. These investigators concluded that, apart from age and gender, aetiology has a signicant impact on surgical outcomes [46].
21.20 German Series (Second German Series)
In a series from 1970 to 1990 inclusive from University Hospital, Erlangen, Germany by Tirilomis and colleagues, 71 consecutive patients with constrictive pericarditis were reviewed. The mean age was 44.2±16.1years [98]. Preoperatively,
43.6% were in NYHA Class III and 35.2% in Class IV.The operative approach was median sternotomy in 93% and left anterolateral thoracotomy in 7%. Perioperative mortality was 5.6%. At a median follow-up of 70months (range, 1–159 months) actuarial survival at 5, 10, 15 and 20 years was 84.6 ± 4.5%, 80.1 ± 5.3%,
70.5± 6.9%, and 65.8±7.9%, respectively. Of the 49 survivors, 23% belong to NYHA Class I, 42% to Class II, 35% to Class III, and none in class IV.Negative

predictors for survival were advanced functional class (p<0.01), low-voltage elec­trocardiogram (p<0.01), ascites (p<0.01), orthopnoea (p<0.05) and hyperbiliru­binaemia (p<0.05) [98].
These investigators concluded that poor outcome relates to preoperative disabil­ity, the degree of constriction and myocardial involvement, and recommended early pericardiectomy through a median sternotomy for good long-term results [98].

21.21 The Johns Hopkins Medical Institutions, Baltimore,
Maryland, USA (Second Johns Hopkins Study)
In another series from Johns Hopkins Hospital, deValeria PA and associates anal­ysed the record of 60 consecutive patients undergoing pericardiectomy between 1980 and 1990. The indication for operations was effusive-constrictive disease in 24 patients and constrictive pericarditis in 36 patients [36].
The operative approach for pericardiectomy was median sternotomy in 52 and left anterolateral thoracotomy in 8 patients. Two patients required cardiopulmonary bypass for dense adhesions, and 2 additional patients who underwent pericardiec­tomy in association of coronary artery bypass grafting. The perioperative mortality was 4.2% and 5.6%, respectively for pericardial effusion and constriction respec­tively [36].
At a median follow-up of 56.9± 38.2 months, the actuarial survival at 1year, 5years and 10years was 82.1±5.1%, 71.7±6.7%, and 59.8±12.2% respectively. Cox proportional hazard analysis revealed history of malignancy, previous cardiac surgery, and advanced preoperative NYHA Class as predictors of poor survival. They concluded that complete pericardiectomy can be performed safely with good long-term functional results. Patients with effusive-constrictive disease that is resis­tant to conservative methods should undergo complete pericardiectomy rather than a limited procedure. Patients with chest pain refractory to steroid therapy can be relieved of symptoms with the operation [36].
21.22 Swedish Series
In a series from Karolinska Hospital, Sweden by Astudillo and Evert, 36 patients with constrictive pericarditis from 1969 to 1984 inclusive were reviewed. Twenty­six of 36 (72%) patients had pericardial calcication and 44% (n=16) were idio­pathic. Left anterolateral thoracotomy was employed in 35 cases. Median sternotomy was used in one patient due to extensive left pleural calcication. There were 3 (8.3%) early and 11 (30.5%) late deaths. Actuarial survival at 5 and 10years was 77% and 69% respectively [1].
372
https://t.me/medicina_free
At a median follow-up of 8 (range 2–17years), 16 of 33 (49%) patients were asymptomatic. Lack of postoperative improvement was related to severe, non­resectable calcications, and probably in some cases to associated brous pericar­ditis or restrictive myocardial disease. These investigators concluded that left anterolateral thoracotomy permits easier and more complete left ventricular pericar­diectomy, but is less safe when severe calcications involve the right ventricle and right atrium [1].

21.23 Christian Medical College andHospital, Vellore
Series, India
In 1988, Basi VV and associates investigated a total of 118 patients who undergoing pericardiectomy for constrictive pericarditis between 1954 and 1985 at Christian Medical College and Hospital, Vellore, India. Ages ranged from 10 to 50 (mean 27±11.5) years. Aetiology of constrictive pericarditis was tuberculosis in 72 (61%) of cases. Preoperatively, 97 (82.2%) patients were in NYHA class III or IV. Pericardiectomy was accomplished through left anterolateral thoracotomy in 107 cases, median sternotomy in 3 cases, and bilateral thoracotomy in 8 cases [6].
Postoperative low cardiac output syndrome was present in 34 (28.8%) patients, 12 (35.3%) of whom died. Overall perioperative mortality was 16%. possibly related to improvements in perioperative care.
Of the 99 survivors, 78 were followed from periods ranging from 2 to 30 (mean±SD, 9±6.5) years. Of the 72 patients in whom functional capacity could be assessed, 59 were in NYHA class I, four in class II, and 9in class III.There were 6 cardiac-related deaths. None required re-operation for recurrent constriction. These investigators concluded that poor results of pericardiectomy in some patients are likely to be related to advanced preoperative disability, and recommended early pericardiectomy, whenever possible [6].
21.24 Turkish Series
Yetkin U and associates in 2003 reviewed 42 consecutive cases of constrictive peri­carditis undergoing pericardiectomy for chronic constrictive pericarditis between 1994 and 2002 [107]. The average age was 39.3years (range 17 to 63 years). Pericardial calcication was present in 18 (42.9%) patients. Tuberculosis was asso­ciated with calcication in 16 of the 18 (88.8%) patients. All patients underwent total pericardiectomy via median sternotomy. In 4 of 18 patients with calcic peri­cardial plaques, the investigators left large plaques that did not permit the develop­ment of a cleavage plane. In these cases, they performed wedge incisions that reached the epicardium, which reduced the size of the plaques and reduced

myocardial constrictions. No patient required cardiopulmonary bypass due to severe calcication or adhesions. Five patients required cardiopulmonary bypass for addi­tional cardiac surgery. Three patients required post-operative intra-aortic balloon counterpulsation for low cardiac output syndrome.
Perioperative modality was 11.9%. Within 1month, the number of patients in NYHA class IV moved from 18 (preoperative) to 1; in class III from 20 to 6, in class II from 4 to 13, and in class I, from 0 to 22. These authors recommended a median sternotomy approach for chronic constrictive pericarditis, and cardiopulmonary bypass in indicated cases [107].

21.25 Series fromTehran, Iran
Ghavidel AA and associates in 2012 reviewed their experience on 45 patients under­going pericardiectomy between 1994 and 2006. The mean age was 46.6±14.9years (range 21–84 years). The aetiology of constrictive pericarditis was idiopathic (n=27, 60%), tuberculosis (n = 10, 22.2%), chronic renal failure (n= 4, 8.9%), post-pericardiectomy (n=2, 4.4%), and neoplastic (n=2, 4.4%). Pericardial calci­cation was detected in 20% of patients on plain chest radiograph. The surgical approach was median sternotomy in 43 patients and left anterolateral thoracotomy in 2 patients [47].
Cardiopulmonary bypass was performed in 9 (20%) patients. The left phrenic nerve was sacriced in 2 patients because of severe calcication and adhesion of the nerve to the pericardium. Severe haemodynamic instability in 4 (8.9%) patients, concomitant valve replacement in (6.7%), and severe iatrogenic intraoperative bleeding in 2 (4.4%) were the primary reasons for use of cardiopulmonary bypass.
At a mean follow-up period of 40±18months (range 3–144months), one (2.3%) patient was in NYHA Class III, while the rest were in Class I.The overall mortality rate was 4.4%. These investigators concluded that pericardiectomy remains an effective procedure in the treatment of constrictive pericarditis with low mortality rates and excellent functional outcomes. Despite intensive vaccination and use of anti-tubercular drugs, tuberculosis remained an important cause of constrictive peri­carditis in Iran [47].
21.26 New York Medical Center, USA
Culliford AT and associates in 1979 reviewed their experience on 27 patients under­going pericardiectomy at New York University Medical Centre over the past 13years. The mean age was 47years (range 10years to 64years) [22].
The duration of symptoms prior to denitive diagnosis and treatment varied between 2months and 10years. The surgical approaches employed were median sternotomy (n=13, 48%), left anterolateral thoracotomy (n=7, 26%), and bilateral

thoracotomy (n=7, 26%). Twenty-two (81.5%) patients underwent radical pericar­diectomy, and 5 (18.5%) patients underwent limited pericardial resection. Four patients were placed on cardiopulmonary bypass; one patient underwent aortic valve replacement for severe aortic regurgitation. The median sternotomy was asso­ciated with the shortest period of hospitalization—13.6 days. In the group of 4 patients undergoing pericardiectomy using cardiopulmonary bypass, the postopera­tive hospitalization averaged 25.8days. There was 1 (4%) postoperative death, and no late deaths at a mean follow-up period of 4years (range 3months-12years).
Intraoperative pressure measurements demonstrated that radical pericardiectomy immediately corrects haemodynamic abnormalities. Most patients underwent mas­sive diuresis (7 to 16kg) within 2weeks with an uneventful recovery. These inves­tigators concluded that two traditional concepts on pericardiectomy are erroneous: i) pericardiectomy limited to the anterior and lateral surfaces of the ventricles is an adequate operation, and ii) delayed recovery is due to myocardial ‘atrophy’ and not to inadequate resection [22].

Reuter H and associates reported 30-day and one-year outcomes of large effusive pericarditis on 233 consecutive patients between 1995 and 2001. 162 patients had pericardial tuberculosis, including 118 (73%) with microbiological and/or histo­logical evidence of tuberculosis and 44 (27%) diagnosed on clinical and supportive laboratory data. They were treated with anti-tubercular drugs, and underwent echo­guided pericardiocentesis and extended daily intermittent drainage via an indwell­ing pigtail catheter. Over the 6-year period, 2 patients developed brous constrictive pericarditis after receiving antitubercular drug and adjuvant corticosteroid ther­apy [82].
The 30-day mortality (8%) was statistically higher for HIV positive patients than for HIV negative patients (9.9% vs 6.2%, p=0.04). The one-year all-cause mortal­ity was 17.3%. It was higher for HIV positive (22.2%) than for HIV negative patients (12.3%, p = 0.03). They concluded that tubercular pericardial effusion responds well on closed pericardiocentesis and a 6-month treatment of antitubercular drugs [82].
