Diagnosis
The patient was diagnosed with severe pulmonary regurgita­tion several years post percutaneous pulmonary valvulo­plasty with clinical symptoms of the right ventricular failure.
Comment
Percutaneous pulmonary valve replacement was recom­mended for the patient.
Lesson
Moderate pulmonary insuffi ciency occurs in between 25 and 33 % of post pulmonary valvuloplasty cases. However, severe pulmonary insuffi ciency is uncommon, and it requires inter­vention if it occurs in association with symptomatic right-sided failure [ 116 ]. Pulmonary insuffi ciency is related to oversized balloon even in the recommended range of 120–130 % of annulus diameter. It seems better to accept mild degrees of stenosis for avoiding pulmonary insuffi ciency [ 139 ].

A 22-year-old woman presented with dyspnea (functional class III) and cyanosis with clubbing. She was a known case of complex cardiac diseases from childhood and had
undergone surgery at 6 months old. O 2 saturation was 44 % in room air, which reached 77 % with oxygen.

Diagnosis
The patient had a double-outlet right ventricle and a subpul­monic VSD. Accordingly, a diagnosis of Taussig–Bing anomaly causing the Eisenmenger’s syndrome was established.
Comment
The patient had undergone pulmonary artery banding at 6 months old, but it was ineffective. We recommended treat­ment with bosentan and sildenafi l for her. Our surgeons rec­ommended catheterism; there were two possibilities: if the pulmonary artery saturation was more than the aortic satura­tion, they would do atrial switch, and if the pulmonary artery saturation was less than the aortic saturation, they would per­form interatrial septectomy.
Lesson
In the Taussig–Bing anomaly, in which there is a subpul­monic VSD, the O2 saturation of the pulmonary artery is more than that of the aorta. The pathology, therefore, is simi­lar to the transposition of the great arteries [ 140 ].
Fig. 119.8 There is an overriding of the pulmonary artery on the
interventricular septum. More than 50 % of the pulmonary artery origi­nates from the right ventricle. The VSD is under the pulmonary artery. PA pulmonary artery

A boy with a history of cyanosis and dyspnea on exertion (functional class III–IV) was referred to our echocardiogra­phy laboratory. Echocardiography revealed right ventricular
dilation with moderate atrioventricular valve regurgitation and severe pulmonary arterial hypertension (peak systolic arterial pressure of about 100 mmHg).

Fig. 120.2 The apical four-chamber view reveals that the pulmonary
veins drain into a left-sided atrium; this is indicative of the situs solitus of the left atrium. Also, the moderator band is in the right ventricle ( arrowhead ), which is in favor of D-loop ventricles. PV pulmonary vein, LA left atrium, LV left ventricle, RA right atrium, RV right ventricle

A 22-year-old woman was referred to our clinic because of multiple abortions. She had dyspnea on exertion (functional class II). Physical examination revealed an early diastolic murmur in the aortic area. The O
2
saturation of the patient was 83 % by pulse oximetry in room air. Electrocardiography showed normal sinus rhythm, right axis deviation, and equal R and S in lead V1. Chest X-ray revealed hypovascularity of the lungs and cardiomegaly. Transthoracic echocardiography showed normal left ventricular size and mild systolic dys­function, normal right ventricular size and function, and mild mitral and tricuspid regurgitation with a tricuspid regurgita­tion gradient of about 70 mmHg.
