Catastrophic presentation of anomalous origin of right pulmonary artery in a neonate--an interesting differential!

A 36-hour-old term neonate presented with refractory cardiogenic shock and multi-organ dysfunction. On suspecting coarctation of aorta, intravenous prostaglandin was started but without any benefit. Echocardiography revealed isolated anomalous origin of right pulmonary artery from ascending aorta causing massive aortic steal, supra-systemic pulmonary arterial hypertension (PAH), multi-organ dysfunction and right ventricular failure.

Pulmonary artery bypass for in-stent stenosis following angioplasty for isolated pulmonary Takayasu arteritis.

Pulmonary artery (PA) stenosis due to Takayasu Arteritis (TA) is usually managed by angioplasty techniques. We present a patient with isolated PA stenosis with TA with in-stent stenosis. The surgical management and pathophysiology of this disease are reviewed.

Calcified unruptured sinus of Valsalva aneurysm in a child.

Sinus of Valsalva aneurysms (SOVAs) might be congenital or acquired in origin. They might present as a rupture or as a consequence of compression on adjacent structures. The treatment of such aneurysms in adults is well documented.

d-Transposition of the great arteries in a 12-year-old child: is arterial switch still an option?

Arterial switch surgery for d-transposition of great arteries is usually performed in the first 2 weeks of life before the left ventricle regresses. The arterial switch surgery that helps achieve anatomic and physiologic correction of this condition has better long-term outcomes than other surgical approaches. The procedure may still be attempted at an older age where the left ventricle has not regressed.
