Diagnosis and treatment options for sinus of Valsalva aneurysms: A narrative review.

Sinus of Valsalva aneurysm (SoVA) is a rare cardiac defect that may be congenital or acquired. It is characterized by abnormal dilatation of the aortic root due to a weakened elastic lamina at the junction of the annulus fibrosus and the aortic media. SoVAs are present in approximately 0.09% of the general population and comprise up to 3.5% of all congenital cardiac defects. It is usually found incidentally on cardiac imaging, with a higher incidence observed in the Western populations and a male-to-female ratio of 4:1. A transthoracic two-dimensional echocardiogram is the initial diagnostic test of choice, which may reveal the characteristic "windsock deformity" that clinches the diagnosis. Other imaging modalities, such as transesophageal echocardiography and cardiac computed tomography angiography, help provide more extensive details of the aneurysm and its adjacent structures. Management options for ruptured and unruptured SoVA include surgical repair or transcatheter closure, which serves as a game-changing development in treatment. This article aims to provide background information on the epidemiology, pathophysiology, diagnosis, and recent advancements over the past decade in the management of SoVAs.
