Tricuspid Valve Repair with a Bridging Technique Across the Valve for Tricuspid Stenosis and Regurgitation at the Norwood Procedure

Abstract

Moderate or severe tricuspid regurgitation is a poor prognostic factor for hypoplastic left heart syndrome (HLHS) and may require tricuspid valve repair at the time of the Norwood procedure. If complicated with tricuspid valve stenosis, a technique that does not worsen the stenosis must be selected. We present such a case; a male infant prenatally diagnosed with HLHS and underwent surgical repair of the valve on the 20th day of life. We performed a bridging technique across the tricuspid valve for repair of tricuspid regurgitation and stenosis associated with HLHS at the time of the Norwood procedure and successfully controlled regurgitation without worsening stenosis. This technique does not restrict the tricuspid valve inflow and is suitable for cases of combined tricuspid regurgitation and stenosis.
