A 28-year-old female presented with dyspnea on exertion for the last three years. Clinical examination showed presence of systolic murmur over 2nd intercostal space radiating to ipsilateral axilla. Trans-Oesophageal Echocardiography (TTE) revealed enlarged Right Atrium (RA), Right Ventricle (RV) and Left Atrium (LA). TTE also showed presentation of a ball in the right atrial cavity [Table/Fig-1], along with normal bilateral ventricular function and left to right shunt [Table/Fig-2].

Cardiac catheterization study confirmed Rupture Sinus of Valsalva (RSOV) arising from right coronary sinus and projecting to right atrium with oxygen step-up in RA. Intraoperatively the enlarged, globular mass seen in RA [Table/Fig-3] was plicated and Poly Tetra Flouro Ethylene (PTFE) patch closure of aortic end of the sinus was performed.

Ruptured sinus of valsalva aneurysm, a rare but well-recognised clinical entity, is invariably a form of left-to-right shunt due to rupture into right-sided chambers. This condition is found more commonly in Asians than western population . Recently, Xin-Jin L et al., have proposed a modified Sakakibara classification system for RSOV aneurysm according to the site of rupture . Surgical closure is the backbone of therapy for RSOV and has operative mortality of <5 % . Transcatheter closure has been proposed as a safe and effective alternative to traditional surgical correction in selected cases [4,5].
