A Giant Ruptured Noncoronary Sinus of Valsalva Aneurysm: A Case Report.

The occurrence of a giant ruptured aneurysm originating from the noncoronary sinus of Valsalva in the right atrium is extremely rare. Herein, a case is presented of a giant ruptured noncoronary sinus of Valsalva aneurysm (SVA) that was protruding into the right atrium, which was almost completely occupied by an aneurysm. A 61-year-old female was referred to the hospital for exertional palpitation and dyspnea. While a surgical repair was performed by resection of the aneurysm and a sinus remodeling with a patch of fresh bovine pericardium, a very rare case was observed. It was a giant ruptured noncoronary sinus of aneurysm that completely occupied the right atrium, which was difficult to distinguish from the coronary aneurysm. It is also believed that various imaging examinations, such as cardiac computed tomography angiogram (CCTA) and transthoracic echocardiogram (TTE), were useful for the diagnosis.
