Ruptured aneurysm of the sinus of Valsalva in association with persistent left superior vena cava--a case report.

A 58-year-old man presenting with chest pain and dyspnea was diagnosed by transesophageal echocardiography and cardiac catheterization to have the rare combination of ruptured aneurysm of noncoronary sinus of Valsalva into the right ventricle in association with persistent left superior vena cava. These defects were confirmed at cardiac surgery. This case shows the importance of complementary use of invasive and noninvasive methods together in the diagnosis of rare combinations of lesions.
