Surgical repair of congenital stenosis is an effective procedure with acceptable surgical risk and good late survival, but late morbidity is not negligible, especially in infants and when associated pulmonary artery stenosis is present.

Anomalous origin of the left coronary artery from the right pulmonary artery in association with hypoplastic left heart syndrome is a rare congenital anomaly. We describe a successful simultaneous surgery for both anomalies during the first stage palliation in a neonate.

Cor triatriatum dexter is an extremely rare congenital anomaly of the right atrium. It occurs because of the persistence of the right sinus venosus valve, resulting in partitioning of the right atrium. Most of the described cases of cor triatriatum dexter in the literature were incidental findings on echocardiogram or at necropsy. We present a case report of a 7-year-old girl who was referred to us for further assessment, with a possible diagnosis of coarctation of the aorta. Initial investigations confirmed not only the presence of a long segment coarctation of the aorta, but also a large obstructive membrane in the right atrium. A catheter intervention was performed to stent the coarctation segment, and the fibro-muscular shelf in the right atrium was surgically resected.

Aortic arch thrombus is a rare occurrence in neonates. In the few described cases, this has mainly been associated with sepsis or early postnatal interventions, such as insertion of umbilical arterial line. We describe a case of occlusive aortic arch thrombus in a neonate who presented with signs of critical coarctation and successfully underwent surgical thrombectomy on deep hypothermic circulatory arrest. We also present a review of the most recently published cases of aortic arch thrombus in neonates and the treatment options employed.
