Herein, we present the echocardiographic diagnosis of a case of left sinus of Valsalva aneurysm with rupture into the right atrium.
Keywords: Left sinus of Valsalva aneurysm; Right atrium; Echocardiography
A 24-year-old woman, with a history of continuous murmur at the left sternal border, was complaining of dyspnea and palpitation on exertion. The ECG showed incomplete right bundle branch block and mild cardiomegaly on chest roentgenogram. Transthoracic echocardiography revealed an aneurysm of the left sinus of Valsalva (ALSV) that had ruptured into the right atrium, with left to right shunting. The right atrium (RA) was mildly enlarged. A modified parasternal short axis view showed the entry point of the aneurysm in the left coronary sinus, and a tortuous tunnel (arrows in panel A) (Fig. 1). In the RA, there was a draining wind-sock orifice (arrows in panel B). Continuous flow was observed in the aneurysm (panels C and D). Diagnosis was confirmed with cardiac catheterization. During surgery the opening of the aneurysm was identified in the left coronary sinus and localized between the separate ostiums of the left anterior descending and circumflex coronary arteries. The opening was closed with a Dacron patch and the draining orifice in the RA was sutured. The patient did well after surgery. Most aneurysms of sinus of Valsalva arise from the right or non-coronary sinus. Only 1% arise from the left coronary sinus and rupture into the RA is extremely unusual.
