From: Giant unruptured sinus of Valsalva aneurysms causing angina pectoris
(A) Coronary angiography showed persist swirling of contrast within a large aneurysmal left-coronary sinus of Valsalva. (B) Left anterior descending artery was retrogradely perfused by the right coronary artery. Transthoracic echocardiography showed unruptured left-coronary (C) and non-coronary (D) sinus of Valsalva aneurysms. SVA: sinus of Valsalva aneurysm; DIAG: diagonal branch artery; LAD: left anterior descending artery
