Combined superior-transseptal approach to the left atrium

The combined superior-transseptal approach to the left atrium was used in 22 patients: to perform a mitral valve repair in 14 patients and mitral valve replacement in 8 patients. Mitral valve operation was combined with other cardiac procedures in 18 patients (82%) and was performed as a reoperation in 3 patients (14%). In all cases there was excellent exposure of the complete mitral annulus and subvalvar apparatus. There were no instances of postoperative bleeding, conduction defects, or intraatrial shunting related to the approach. The combined superior-transseptal approach to the left atrium is an excellent approach that can be used in most reoperations and primary procedures for isolated or combined mitral valve operations.
