Abstract

Sinus of Valsalva aneurysms are rare cardiac anomalies that may be acquired or congenital. We describe the case of a patient who had an unruptured sinus of Valsalva aneurysm causing right ventricular outflow obstruction, with an associated subaortic ventricular septal defect. Sinus of Valsalva aneurysms rarely present until rupture occurs. However, the unruptured aneurysm of the right sinus of Valsalva caused significant right ventricular outflow tract obstruction, resulting in exertional dyspnea. Intraoperative multiplane transesophageal echocardiography and color Doppler helped in precise identification of structural anomalies, shunt location, and definitive surgical repair.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
