Rupture of Sinus of Valsalva Aneurysm Associated with Infective Endocarditis in a 39-Year-Old Patient with Congenital Ventricular Septal Defect and Subvalvular Pulmonary Stenosis: A Case Report

Aneurysm of the sinus of Valsalva is a rare congenital lesion that may be associated with other congenital lesions such as ventricular septal defect (VSD). Less common lesions can occur secondary to trauma, infective endocarditis, or syphilis. The majority of these aneurysms originate from the right coronary sinus. Patients with unruptured aneurysms usually remain asymptomatic. Rupture of the aneurysm usually causes the appearance of a continuous murmur in the left sternal border. Locations of the common ruptures include the right ventricle, the right atrium, and less commonly the left atrium. Surgical repair of the tear usually has optimal outcomes. We describe a 39-year-old man with a history of congenital VSD, subvalvular pulmonary stenosis, and rupture of the right sinus of Valsalva aneurysm complicated by infective endocarditis.
