A 23 year old man was operated on because severe incompetence of the aortic, mitral, and tricuspid valve caused congestive heart failure five months after a violent steering wheel injury. The following abnormalities were found at operation: a disrupted right coronary cusp, a torn chorda of the anterior mitral leaflet, a dilated tricuspid annulus, and an intimal tear on the aortic root near the right coronary ostium that had developed into an aneurysm of the sinus of Valsalva.
