Abstract
Many dangers attend mitral valve replacement in the presence of dense posterior annular calcification. The procedure described has been successful in 4 patients. The major elements of this procedure include complete ultrasonic debridement of the calcification, reconstitution of the disassembled atrioventricular groove, and retention of the mitral valve leaflets.
