Is the Anterior Intertrigonal Distance Increased in Patients With Mitral Regurgitation Due to Leaflet Prolapse?

Although the posterior mitral annulus is enlarged in patients with significant MR due to degenerative leaflet prolapse, there is no evidence that the intertrigonal distance is abnormal in these patients. Our data support the conclusion that posterior annular reduction with a flexible device at the time of mitral valve repair is important, and that altering the anterior intertrigonal portion of the mitral annulus is unnecessary.
