Sinus of Valsalva Aneurysms (SVAs) are rare cardiac defects that can be either congenital or acquired. The greatest concern is the risk of rupture. Even if unruptured, they can obstruct adjacent structures such as the coronary artery ostium or the right ventricular outflow tract. SVA are also associated with malignant arrhythmias and endocarditis,1 and there is 3:1 male predominance. Although still rare, SVAs are both more common and up to five times more likely to rupture among Asian populations compared to Western populations.2,3 Rupture most commonly occurs in patients between 20-30 years of age.
