[Successful surgical treatment of aortic regurgitation with coronary artery fistula due to blunt chest trauma--a case report]

Abstract

A Successful repair of aortic regurgitation with coronary artery fistula due to blunt chest trauma is reported. A 17-year-old boy was involved in a motor cycle accident, but there were neither open chest trauma nor rib fracture. On admission diastolic regurgitant musical cardiac murmur was noted. Color doppler echocardiogram showed severe aortic regurgitation. But any cardiac murmur had nerve been noticed before. CAG showed a fistula from the acute marginal branch of the RCA to the RV. But no shunt existed on calculation. The aortic valve was explored under cardiopulmonary bypass. There were a tear in the LCC and a fissure in the RCC. Otherwise the valve tissue appeared normal. The valve was excised and replaced with a integral of 21 mm Björk-Shiley valve prosthesis. The fistula was left because there were no abnormal findings on the RCA and no significant shunt. The patient is up and well 1 year and 10 months after operation. This is the first report of aortic regurgitation with coronary artery fistula due to blunt chest trauma.
