Blunt trauma followed by aortic valvular insufficiency is a rare occurrence. In one case, a male high-school student who had sustained a non- penetrative chest injury suffered from aortic regurgitation resulting from the rupture of the normal aortic valve. A sizable tear in the non-coronary cusp caused aortic insufficiency. The case was treated successfully by surgical replacement of the aortic valve with a No. 21 SJM prosthesis.
