Congenital Aneurysm of the Left Sinus of Valsalva: Report of a Patient with 19-Year Survival without Surgery

An unruptured aneurysm of the left sinus of Valsalva was diagnosed by angiography in a 16-year-old male subject 19 years ago. A recent repeated angiographic study documented no change in the aneurysm over the 19-year interval, and the patient has remained asymptomatic. We are aware of no other long-term follow-up reports of patients with this lesion who have not had surgical correction. This case emphasizes the controversy regarding the need for prophylactic surgical correction of an unruptured aneurysm.
