Aortic regurgitation caused by fibrous strand rupture in a fenestrated aortic valve.
Fibrous strand rupture in a fenestrated aortic valve can cause acute severe aortic regurgitation. We report the case of a 56-year-old woman with severe aortic regurgitation. Transesophageal echocardiography showed an abnormal fibrous strand echo on the prolapsed left coronary cusp (LCC). The operative finding revealed one ruptured fibrous strand attached to the LCC at the commissure between the left and noncoronary cusps. Pathologic examination of the aortic valve revealed myxomatous degeneration.
