Novel percutaneous femoral arterial-transthoracic approach for closure of ascending aortic pseudoaneurysm with a septal occluder device in a child.

Ascending aortic pseudoaneurysms are a rare complication following cardiac surgery. Their traditional surgical management carries high morbidity and mortality, especially in patients with multiple comorbidities. Transcatheter closure of these pseudoaneurysms using a septal occluder device has been previously reported in adults as an alternative approach with fewer complications. We report the first case of a novel percutaneous femoral arterial-transthoracic approach for exclusion of an ascending aortic pseudoaneurysm with an Amplatzer atrial septal occluder device in a 9-year-old child with Takayasu's arteritis.

Rupture of sinus of Valsalva aneurysm with aorto-biventricular fistulas and right-ventricular outflow tract obstruction: a unique association.

Sinus of Valsalva aneurysms are a rare entity. Rupture of such aneurysms is a major cause of aortocardiac fistulas usually occurring between the right sinus of Valsalva and right cardiac chambers. We report an exceptional case of a ruptured congenital sinus of Valsalva aneurysm with fistulas involving both the right- and left-ventricular outflow tracts and causing RVOT obstruction. We also demonstrate the utility of computed tomography angiography and transesophageal echocardiography in diagnosing these fistulas.
