Endoscopic Surgery for Cardiac Tumours
Abdelrehman Abdelbar and Joseph Zacharias
Abstract
With increasing experience in endoscopic techniques a sub group of patients who could benet from this approach are patients pre­senting with a diagnosis of cardiac tumours. These are often picked up as an incidental nding and once the diagnosis is made early surgery is warranted. These can provide challenges to get a team together but if an institution offers this approach as a routine, then these cases can be dealt with quickly. In this chapter we summarise some of the case series in the literature and present a case to show the pathway followed. We also include a video to capture the key steps.

Papillary broelastoma
1 Epidemiology and Pathology
Cardiac neoplasms are extremely rare conditions which are represented by a small group of patient population even in large tertiary cardiac surgery centres [1]. Due to the current status of many of these being under diagnosed, it is very difficult to estimate an accurate prevalence in the living population. The disease load is only obtained from post-mortem studies. These studies have shown that primary cardiac tumors are rarer than secondary deposits with an incidence of 0.05% and 1% respectively. This percentage does not reect the real practice or case load in the cardiac centres. It is likely that cardiac tumors are underdiagnosed in the real world of clinical practice [2]. Despite the advances and the wide use of cardiac imaging modalities, cardiac tumors are rarely symptomatic and most patients have an incidental pick up following on from an imaging study.
Likewise, to any tumour, cardiac tumours are classied into primary and secondary tumours. Primary cardiac tumours are further divided into benign and malignant.
Benign cardiac tumours include Myxoma (represents 50% of all primary cardiac tumours), rhabdomyoma, lipoma, broma and angioma. Malignant cardiac tumours are mainly sarcomas (e.g. angiosarcoma and rhabdom yosarcoma) or lymphomas. Secondary cardiac tumours are usually part of a widespread malignancy which is

not only limited to the heart. Metastasis to the heart is most commonly linked to lymphoma, leukaemia and melanoma.
Clinical presentation of cardiac tumours is extremely variable. It depends on the location and the size of the tumour. Most of the cases will be asymptomatic, the diagno sis of which is usually post-mortem. When symp tomatic, car­diac tumours are usually presented by one of three classic features. This triad is obstruction, embolic phenomena and constitutional symp­toms. Depending on the size and position of the tumour, the effects on the haemodynamics and the site of embolisation are determined. For example, a tumour on the right side of the heart will cause pulmonary embolic manifestations while those on the left are more likely to lead to systemic emboli and its effects. Other presenta­tions might be arrhythmia in case of tumours invading the myocardium. A tumour invading the pericardium might cause pericardial effusion and possible cardiac tamponade.
2 Role of Minimally Invasive
Surgery
Generally speaking, minimally invasive surgery is still under-performed in cases of cardiac tumours. This is since cardiac tumours them­selves are rare in clinical practice. The increased availability and utilisation of cardiac echocar­diogram has incre ased the number of diagnosed cases, yet, the overall case load is still under 1% of the performed cardiac surgery cases in the United Kingdom. The argument for expanding the role of minimally invasive surgery is to obtain both its well-recognised post-operative benets and, the comparable or even superior tumour clearance.
Post-operative benets of minimally invasive surgery are well described in the literature [3, 4]. They include faster patient recovery, less blood loss with consequent less blood transfusion, less wound complications, shorter intensive care and overall hospital stays [5, 6]. The morbidity and mortality were found to be less in minimally invasive surgery. Benets of minimally invasive
surgery will extend to post discharge benets in terms of shorter rehabilitation requirements and quicker return to work [7, 8]. All these factors are likely to support increased execution of mini­mally invasive surgery for better patient care and improvements of the wider health care economy.
In terms of tumour clearance, minimally invasive surgery provides better visualisation of the intra-cardiac structures which, in turn, results in more specic excision. The use of high de­nition and 3D endoscopes has enabled easy navigation in the difficult access areas such as the ventricles through the corresponding atrio­ventricular valves which can give a wider working area. In contrast, when sternotomy is utilized, ventricles were accessed through aortic and pulmonary valves which gives a narrower eld and increases the risk of injury to those ne valves.
So far, the evidence in terms of minimally invasive resection of cardiac tumors is still rely­ing on case reports, case series [9] and fewer meta-analysis papers. Due to the small numbers and the urgent presentation a randomized con­trol trial is unlikely to be carried out and hence high grade evidence will always be lacking [10].
Some case series have shown the results of MICS approach for resection of cardiac tumors to be excellent. For example, our experience [11] reported the results of 20 patients. This case series showed 18 patients with left atrial myxoma and two with left ventricular broelastoma. We highlighted the safety of the procedure with no mortality, stroke or conversion to sternotomy. No recurrence of the tumors was reported. Likewise, Deshpande et al. reported more variable tumor pathologies and sites [9]. Their case mix showed right and left atrial myxomas, aortic valve ­broelastoma, tricuspid valve intravenous leiomyoma with inferior vena cava involvement and plexiform tumor of the sinoatrial node. They have reported no post-operative complications with no recurrence in 27 patients for a median follow up for 3.4 ± 2.7 years. Bianchi et al. reported 30 patients who underwent excision of left atrial myxoma via MICS approach with no hospital mortality or stroke. They have
Endoscopic Surgery for Cardiac Tumours 239
experienced no recurrence in a follow up median of 55.6 ± 32.3 months [8].
While the previously mentioned studies lack comparison with MS, some other teams reported their comparative results in both MICS and MS. Lee et al. compared their retrospective results of 143 MS and 63 MICS patients (total 203 patients) [5]. In this study, they have selected only patients with cardiac myxoma and excluded patients with any accompanied cardiac patholo­gies including valve haemodynamic pathologies. They concluded the superiority of the MICS approach in terms of blood transfusion and postoperative arrythmia. They did not nd a signicant difference in the post-operative ven­tilation or hospital stays. They have also reported a longer cardiopulmonary bypa ss and cross clamp times in the MICS group which did not reect on the post-operative results. Conversely, Iribarne et al. did not nd that CBP and cross clamp times were longer in the MICS than in MS [6]. They argued that MICS excision of cardiac tumors is performed by experienced MICS teams with already a large MICS valve practice. In the same study, which included 36 MS and 38 MICS (total 74 patients), they have also reported a shorter hospital stay and freedom of recurrence for a mean time of 4.8 years. Pineda et al. reported the results of 39 patients (22 MICS and 17 MS) [7]. They have concluded that with similar outcome in terms of post-operative complications, MICS poses better utilization of resources because of the associated shorter ICU and hospital stays in these case series.
Moscarelli et al. performed the rst meta­analysis to compare the outcome between MICS and MS in treating cardiac tumours. They anal­ysed 653 procedures, majority of them were cardiac myxoma (601 patients) [4]. They have concluded excellent outcome of the MICS approach comparable to MS approach or even superior despite the longer CBP and cross clamp times. Tumour size did not inuence the choice of the surgical approach, but they found some hesitation from some surgeons to perform MICS in case of right atrial tumour to avoid tumour
fragmentation during cannulation. There was also no conversion in the MICS group which signies the safety of the procedure and the role of surgical experience with MICS before con­sidering it.
3 Case Scenario
In this section, we will show a step wise approach to a straightforward conrmed case of left atrial myxoma in regard to preoperative, intra-operative and post-operative steps.
To make this case more challenging, we
picked up a female patient with breast implants.
Preoperative imaging:
To decide the suitability of any patient to the MICS, there are a few multi-modality imaging which would help. Some of them can be done intra-operatively eg TOE and groin US.
Echocardiogram:
Final conrmation of diagnosis.
Valvular lesions if any.
Strategy of myocardial preservation. (Table 1)
Role of intra-operative TOE will be discussed in the intraoperative section.
Contrast enhanced CT scan:
Exclude extra-cardiac tumors.
Cannulation strategy:
– Suitable femoral vessels:
Good size femoral arteries with acceptable course eg no tortuosity. Freedom of any venous abnormality eg thrombosed femoral vein.
– Healthy aorto-vascular tree:
No calcications
– Ascending aorta:
Suitable for using Endo-aortic clamp.
Right pleural pathology/adhesions.
Freedom from coronary artery ow limiting
lesions (if ECG gated CT scan is available).

Surgical positioning and set up:
Supine position with 30-degree tilt towards the left side. This can be achieved using an inatable bag below the right-side 4th inter­costal space.
Skin incision is better if performed 1 inch above the femoral crease:
Less wound complications.Larger caliber of the femoral vessels.
Expose only the front service of the vessels to avoid wound complications.

Arterial cannulation: – Always split the arterial inow line. In case
the contralateral groin cannulation/central cannulation is required.
– TOE live monitoring of the descending
aorta until full ow is achieved.
– Arterial inow pressure never to exceed
300 mmHg. If so, bifemoral cannulation.
Venous cannulation: – Live monitoring of the wire and cannula
until cannula is in place.
Generally: never force the guide wires.

Video 1 Step by step video of a left atrial myxoma excision (https://doi.org/10.1007/000-a8c)
Surgical procedure:
In this section, a step-by-step video will be pro­vided. But we would like to point out a few points:
Main surgical incision: – This can vary from a small peri-areolar
incision that enters the chest through the 4th intercostal space in case of endoscopic assisted practice. A larger incision could be utilised at a more lateral position in case of direct vision practice or with pleural adhesions.
– Better to perform muscle splitting instead
of diathermy for less bleeding and better healing.
Other utility incisions (within the axillary lines): – 2nd intercostal space: in case of using an
external cross clamp.
– 3rd intercostal space: 10 mm port for the
camera.
– 5th or 6th intercostal space: for traction and
CO
line (utility port).

Better to perform surgical incisions before heparin administration. Wound closure and
ports removal should be perfor med after reversal of heparin.
Better to use two drains at the end, pericardial and right pleural drains.
It is favored to perform intercostal blocks before closure. (see video)
Tips, Tricks and Traps:
In case of right atrial myxoma near the SVC or IVC, cannulae should be withdrawn to a position distal to the cavo-atrial junctions to allow snaring as described before.
While handling the myxoma, surgeons con- centration should be focused on minimal manipulation of the actual myxoma to frag­mentation and embolization. Instead, nding the stalk of the myxoma and using it for manipulation is safer. This can be achieved by using the external suction gently to retract the tumor until the stalk is exposed.
Large myxomas can be retrieved using a tis­sue retrieval system to avoid fragmentation with subsequent embolization and seeding.
Endoscopic Surgery for Cardiac Tumours 243
Post-operative:
Beside the routine post-operative care, a few points are considered in case of the MICS:
Immediate post-operative chest Xray to check right lung expansion and pleural collection in case of bleeding.
Drains can be removed as per the local pro­tocol. If there is still high output, pericardial drain to be removed in 24 h and right pleural one to be kept in.
Look out for damage to the phrenic nerve as post operative atelectasis at the right lower lobe can also present with a raised right hemidiaphragm.
Despite small incisions the pain around the drain sites can be troublesome so the earlier the drains can come out the better for patient to get involved with Physiotherapy and mobilisation.
Increasingly we are putting the right sided chest drain on a portable suction device so that patients can mobilise easier with the drains left in.

Abstract
Extracorporeal circulation throughout mini­mally invasive cardiac surgery (MICS) is often provided by peripheral artery cannula­tion but is mainly performed through surgical cutdown. Percutaneous placement of cannulas is assisted by vascular closure devices yet their advantages to MICS are still disputed. Hospital stay, operation time and groin com­plications have been substantially reduced through percutaneous groin cannulation using

It is of paramount importance to master a variety of cannulation techniques for safe perfusion strategy and operation. The operative tech­niques for MICS have developed greatly over the past decade to include a wide demographic of patients. Our aim is to describe numerous cannulation strategies and their application and use in different minimally invasive procedures.

surgery is a collaboration of innovative surgical techniques performed through a small incision and entails less surgi cal trauma than full sternotomy conventional cardiac surgery. The limitations of the MICS surgical eld elicit essential adaptations of surgical technology, instrumentation, and can­nulation strategy. When applying MICS tech­niques, a deep and comprehensive grasp of various cannulation strategies and their applica­tion to a wide spectrum of diseases and patients is required. The appropriate strategy for the neces­sary cannulation, allowing for optimal exposure and ease of operation, will depend entirely on the surgical approach. MICS procedures are broad and therefore need a wide array of cannulation options as opposed to conventional sternotomy­based surgery that solely uses the central ascend­ing aortic cannulation with right atrial or bicaval cannulation. Typical MICS techniques include performing an upper hemisternotomy, lower hemisternotomy, and a right anterolateral mini­thoracotomy. Regarding hemisternotomy, some surgeons may choose percutaneous femoral venous cannulation in combination with central arterial cannulation as opposed to the conven­tional central arterial and venous cannulation. A completely femoral platform may also be implemented. Minithoracotomy-based techniques however often need alternative cannulation strategies.
2 Arterial Cannulation
When a patient is placed on cardiopulmonary bypass (CPB) the initial consideration is not only the cannulation size but also the cannulation site [1]. This is inuenced by the presence of disease within the artery, the artery size and the patients body surface area (BSA). It is preferred to can­nulate the femoral artery for peripheral cannula­tion and select the cannula size based on BSA [1]. For a BSA of <1.7, a 15F arterial perfusion can­nula is chosen, and a 17F cannula for a BSA of
1.7 to 2.1 and when the BSA is >2.1, a 19F
cannula is applied [1]. While on CPB, body temperature is maintained at around 34 degrees Celcius. At the authors´institution goal-directed­perfusion with DO
-guided perfusion is used.

This is helpful in regard to optimal venous drai­nage as it allows the surgeon to safely reduce the pump ow to 70–80% of the calculated ow if required [2]. A 3.2 L ow with a cannula pressure of 350 mmHg can be reached with cannula sizes of 15F, 17F, and 19F and 3.5 L or greater ow rates with a pressure of 350 mmHg, and a 4 L ow rate with pressures of 300 to 350 mmHg, respectively [1]. Notwithstanding these smaller cannula sizes, higher cannula pressures and lower ow rates, there is no proof of any clinical con­sequences. An alternative cannulation site is sometimes required should there be evidence of signicant atherosclerotic disease or a small femoral artery. A computed tomographic angiography (CTA) of the chest, abdomen, and pelvis can reveal such essential information and has become routine in high-volume programs with patients undergoing MICS [3]. The authors believe that CTA should be carried out preoper­atively in patients suspected of having aortic and/or peripheral vascular disease [4]. Although the benets are enormously helpful, the disad­vantage of a CTA without contrast is that the subtleties in soft plaque may not be clear and this is an important risk factor to identify prior to peripheral cannulation and retrograde arterial perfusion [2, 5]. An intraoperative nding of grade 4 to 5 atheroma in the descending aorta identied with intraoperative transesophageal echocardiography (TEE) may be a contraindica­tion for retrograde femoral artery perfusion. Safe candidates for peripheral arterial cannulation are those with minimal calcied plaque, thrombus or aneurysmal disease of the aorta [6]. Ipsilateral peripheral arterial access is contraindicated upon conrmation of femoral or iliac dissection or obstructive disease. Should there be any doubt regarding limb ischemia or prolonged cardiopul­monary times, a distal perfusion catheter may be inserted, although this is rarely required.

2.1 Femoral Cannulation
The most prevalent cannulation strategy for MICS procedures, including minithoracotomy, is femoral cannulation and can be achieved either percutaneously or directly via open surgical cut­down [1]. Ultrasound guarantees that the site of cannulation is in the proximal femoral artery regarding percutaneous femoral cannulation and uoroscopy can also be employed to ensure the cannula is optimally inserted and placed. The puncture site is positioned over the femoral head and access is obtained by puncturing at a point 1/3 of the distance along an oblique line from the pubic tubercle to the anterior superior iliac spine [7]. A Seldinger technique is implemented to pass a guidewire after needle access has been made. A ProGlide system (Abbott Vascular Devices, Santa Clara, CA, USA) is then smoothly moved over the guidewire and is followed by progressive dilatation and nally passage of the arterial can­nula. A suture is situated by this device through the anterior wall of the artery which is then tightened following sheath or cannula removal. The Perclose ProGlide device is approved for closure of 5F- to 21F-sized arterial sheaths or cannulas and should therefore only be used on 5 mm or larger vessels. There are other percuta­neous closure device options available, including AngioSeal and Manta devices. The Manta device (Teleex, Morrisville, NC, USA) can close arte­rial access sites after employing 12F to 25F sheaths. To obtain hemostasis a radiopaque stainless-steel lock and resorbable collagen and anchor are sandwiched into the access site [8]. Conversely a collagen plug is used to seal the arteriotomy in the AngioSeal device (Terumo Medical Corp., Somerset, NJ, USA). This device, however, is not acceptable for sufcient arterial perfusion since it can only be used on 6F or 8F arterial sheaths or cannulas. A safe alternative to percutaneous access is direct (open) cannulation of the femoral artery following cutdown. This direct exposure allows for palpation of the artery and avoidance of excessively atherosclerotic areas as well as allowing for the primary repair of the artery should needs be. This approac h, via the right femoral artery, is preferred by the authors
due to the left femoral artery often being used for access during cardiac catheterization. This can result in more difficult left-sided access as well as scarring and hematoma. A 1 to 2 cm vertical skin incision is made above the groin crease, overlying the femoral vessels [9]. The inguinal ligament is then retracted, the vessel exposed proximally on the common femoral artery and a 5–0 Prolene purse-string is then placed. The artery is cannu­lated through this suture using a Seldinger tech­nique. Should higher ow rates be required, or sufcient perfusion is limited due to the use of an IntraClude endo-aortic balloon occlusion device [10] (Edwards Lifesciences, Irvine, CA, USA), a further arterial cannula can be placed in the con­tralateral femoral artery (Fig. 1).

2.2 Axillary Cannulation
Axillary or subclavian arterial access should be followed if signicant peripheral vascular disease has been identied, either preoperatively or at the time of femoral cutdown. After a 3 cm skin incision is made 1 cm beneath the clavicle, medial to the deltopectoral groove, the pectoralis muscles are separated or divided and localization is made throu gh nger guidance of the axillary arterial pulse (taking care not to cause injury or excessive traction on the brachial plexus). Flex­ible vessel loops allow for proximal and distal control of the vessel. The proximal aspect of the artery is clamped with a vascular clamp and the distal loop is retracted. Injury can ensue as the
