Aneurysms of the aortic sinus of Valsalva are rare and generally do not produce symptoms unless the aneurysm ruptures. When rupture occurs, the clinical findings depend to an extent on the site of the aneurysm and the cardiac chamber into which the aneurysm ruptures. We report a case of acute rupture of an aneurysm of the right aortic sinus, which was misdiagnosed as a ventricular septal defect. The clinical condition of the patient deteriorated rapidly, and transcatheter closure of the defect with an umbrella was associated with a fatal outcome.
