Rupture of the sinus of valsalva into the pulmonary artery.

ABSTRACT

Congenital aneurysms of the sinus of Valsalva are rare lesions that can rupture into any cardiac chamber, due to the central position of the aortic root. Rupture into the pulmonary artery, however, is very rare. We encountered an 18-year-old girl with rupture of the right coronary sinus into the pulmonary artery. During surgical correction, the girl was also found to have a small outlet ventricular septal defect, which was obscured by multiple hypertrophied septal trabeculae in the right ventricular outflow tract.
