Sinus of Valsalva aneurysm: An uncommon presentation

Background: sinus of valsalva aneurysm (sva) may be congenital or acquired. they couldmimic ventricular tumor symptoms and cause signs and symptoms of ventricular outflow tractobstruction. they may also involve the conduction system and cause palpitations or syncopalepisodes. both transthoracic echocardiography (tte) and transesophageal echocardiography(tee) serve as quick, noninvasive methods to provide information on size and location ofaneurysmal dilatation and cardiac chamber involvement. these methods can identify anyassociated anomalies or complications. this study presents a patient with unruptured sva.case report: a 46-year-old man, who had been suffering from nonspecific symptoms suchas exercise intolerance and weakness for a few months, referred to our clinic in isfahan (iran).in tte, a large mass was observed in the right ventricle. sva was suspected after meticulousprobing. this diagnosis was confirmed by tee and computed tomography angiography. at openheart surgery, an sva with a lot of clots it was removed.conclusion: sva must be kept in mind when a tumor-like mass is observed in the rightventricle. detailed evaluation would thus be necessary to rule out sva and to prevent wrongdiagnosis and treatment that can sometimes be catastrophic.
