Critical thrombotic obstruction of transverse aortic arch in a neonate

A 3-day-old neonate presented with features suggestive of coarctation of aorta. Echocardiography showed a large organized thrombus in the transverse arch causing obstruction to theaortic arch and carotids with partial recanalization. Patient underwent surgical thromboendarterectomy with arch reconstruction. The evaluation did not reveal any hematological abnormalities and suspected to be due to fetal thromboembolism. Patient improved well, and no neurological deficits were observed during follow-up

Transcatheter closure of large right pulmonary artery-to-left atrial fistula

We report the successful transcatheter closure of right pulmonary artery fistula to left atrium in a six-year-old boy, who had presented with cyanosis and shortness of breath. The two-dimensional echocardiogram with bubble contrast study demonstrated the communication between right pulmonary artery and left atrium. Computerized tomography confirmed the diagnosis and delineated the anatomy. The fistula was closed successfully by a transcatheter trans-septal approach using an 18/20 duct occluder

Epicardial deployment of right ventricular disk during perventricular device closure in a child with apical muscular ventricular septal defect

We report a successful perventricular closure of an apical muscular ventricular septal defect (mVSD) by a modified technique. An eight-month-old infant, weighing 6.5 kilograms, presented with refractory heart failure. The transthoracic echocardiogram showed multiple apical mVSDs with the largest one measuring 10 mm. perventricular device closure using a 12 mm Amplatzer mVSD occluder was planned. The left ventricular disk was positioned approximating the interventricular septum; however, the right ventricular (RV) disk was deployed on the free wall of the RV due to an absent apical muscular septum and a small cavity at the apex. The RV disk of the device was covered using an autologous pericardium. His heart failure improved during follow-up
