Ruptured sinus of Valsalva aneurysm is a rare but well recognized clinical entity. These patients develop congestive heart failure due to biventricular increases in volume as a result of sudden aortocardiac shunting. Traditionally, surgical repair has been the mainstay of therapy. We report a case of a ruptured sinus of Valsalva aneurysm that was successfully closed percutaneously using the Amplatzer duct occluder in a critically ill patient operated on previously for coronary artery disease and presenting with acute congestive heart failure.
