Patient 1: surgical findings. (1) M-A discontinuity (separation). (2) Deposition of fibrous tissue in left ventricular outflow tract. The aortic leaflet of the mitral valve is “floating” in the left ventricular outflow tract. (3) Perforation of the left coronary cusp. (4) Vegetations in left coronary cusp. (5) Small ventricular septal defect. (6) Left ventricular outflow tract.

Patient 2. (A) aortogram (left anterior oblique view) reveals severe aortic regurgitation and a saccular aortic root aneurysm. An important displacement of the mitral valve toward the left is observed in relation to the aortic valve. It was not recognized before surgery. (B) (1 = mitral valve; 2 = aortic root aneurysm.)

The left coronary sinus. (A) The right half of the sinus inserts into the anterior leaflet of the mitral valve. (B) The left half of the sinus inserts into the muscular septum. (L.C.A. = left coronary artery; R.C.A. = right coronary artery.) (Reprinted, with permission, from Liotta D, Cooley DA, Cabrol C.
