Giant left ventricular aneurysm and aortic stenosis in a newborn

Congenital ventricular aneurysm (CVA) is a rare, poorly understood and potentially lethal cardiac anomaly. We report a neonatal case, remitted to our hospital due to a cardiogenic shock. Echocardiographic study revealed a severe aortic stenosis and a giant left ventricular aneurysm. Surgical intervention was carried out with extracorporeal circulation support, but without cardiac arrest, achieving aortic valvulotomy and aneurismal resection. The postoperative course was uneventful during the first 24 h, but on the second day, the patient presented a sudden unexpected cardiac arrest, not responding to the resuscitation manoeuvres.
