Scimitar syndrome is a rare variant of anomalous right pulmonary vein connection to the inferior vena cava and it is associated with other cardiopulmonary anomalies. It generally requires surgery and sometimes it may go unrecognised into adulthood. We report a unique case of a scimitar syndrome variant in a young adult, who was successfully treated percutaneously, after the first misdiagnosis of arrhythmogenic ventricular cardiomyopathy. The cardiac magnetic resonance unveiled the uncommon anatomical pattern, avoiding surgical repair. Cross-sectional imaging is extremely useful in the diagnosis and treatment planning of CHD in adults.

Transposition of the great arteries combined with totally anomalous pulmonary venous connection is extremely rare outside of heterotaxy syndrome. Most reported cases have been treated by a modified atrial switch operation. We report the successful treatment of a neonate with this rare association, repaired by arterial switch operation and connection of the pulmonary venous return to the left atrium.

: The usual surgical practice after repair of a Total Anomalous Pulmonary Venous Connection (TAPVC) is to ligate the vertical vein (VV). Many surgeons find it expedient to leave the VV unligated to reduce pulmonary arterial pressure, decrease perioperative pulmonary hypertensive crisis, provide better hemodynamics postoperatively (1), and enable the adaptation of cardiac chambers to a new workload. Afterwards, the unligated VV may cause significant left-to-right shunt, likewise an atrial septal defect, mandating later surgical ligation or device closure (2). This report details transcatheter occlusion of a patent VV using a device Amplatzer Vascular Plug II, after TAPVC repair in early infancy. The transcatheter occlusion of an unligated VV after repair of supracardiac TAPVC represents an effective alternative to surgical redo. The device Amplatzer Vascular Plug II achieves great results.

Objective: The goal of this study was to determine the patterns of the pulmonary circulation in patients with pulmonary atresia and asplenia., Background: The asplenic cardiac syndromes characteristically have complex cardiac anomalies including pulmonary stenosis or atresia. Definition of the pulmonary artery circulation and pulmonary venous connections is needed for consideration of surgical procedures., Methods: In 35 patients, the sources of pulmonary blood flow, anatomic features of pulmonary arteries and pulmonary venous connections were determined from angiograms or autopsy specimens., Results: The main pulmonary artery was absent or hypoplastic in 91% of patients; most had a ductus arteriosus. The right and left pulmonary arteries were confluent in 90% and usually of normal size (right 71%, left 63%). Total anomalous pulmonary venous connections were present in 38%., Conclusions: The anatomic features of the pulmonary arteries in pulmonary atresia associated with the asplenic cardiac syndrome are usually favorable for palliative surgical procedures. Total anomalous pulmonary venous connection may exist as a complicating factor.
