Device closing RSOV on echocardiogram

Device closing RSOV on echocardiogram

Echocardiogram in apical five chamber view showing a device closing a ruptured sinus of Valsalva aneurysm (RSOV). In earlier days the closure of RSOV needed a major surgery under cardiopulmonary bypass with a midline sternotomy. But now the device closure has made it simpler with much lesser morbidity. The first successful surgical closure of RSOV was reported by Lillehei et al in 1957 [1]. Device closure with PDA device is being done recently. After a transthoracic echocardiogram, a detailed transesophageal echocardiogram is also done to assess the maximum diameter of the RSOV at the aortic end, minimum diameter and the length of the tract (with windsock appearance). The distance from the aortic end of the RSOV to the coronary ostium is specifically measured to check whether the device will impede coronary flow.
