Quadricuspid aortic valves are rarely encountered by the cardiac surgeon during aortic valve replacement. The most common location for the supranumerary cusp is between the noncoronary and the right coronary cusp, located over the membranous septum, which can potentially increase the risk of complete heart block after valve replacement. We present three quadricuspid aortic valve replacements, one of which was complicated by complete heart block postoperatively. We suggest a strategy to possibly avoid this complication.
