BACKGROUND: Left superior vena cava draining to a dilated coronary sinus can cause left ventricular inflow obstruction. Our purpose is to report 4 severely ill patients with this malformation who were operated upon and in whom repair was accomplished using an original surgical approach.
METHODS: An operative procedure was designed, which included complete resection of the wall of the coronary sinus along its entire extension in the left atrium; division of the left superior vena cava; and establishment of the left superior vena cava-right atrial continuity by a wide left superior vena cava-right atrial appendage anastomosis. The series included 1 patient with interrupted inferior vena cava-hemiazygous continuation to left superior vena cava.
RESULTS: There were no deaths. Absence of residual left ventricular inflow obstruction was demonstrated at follow-up in all cases, together with an unobstructed left superior vena cava-right atrial appendage-right atrial connection.
CONCLUSIONS: A predictable relief of the left ventricular inflow obstruction, together with preservation of an adequate drainage for the systemic venous return, were both achieved with this repair.
