Transannular patch repair of tetralogy of Fallot.

Abstract

In surgical correction of tetralogy of Fallot (TOF), transannular patch (TAP) repair has been the most prevalent right ventricular outflow tract (RVOT) reconstruction technique. However, resultant pulmonary regurgitation affects postoperative mortality and morbidity, and reintervention for RVOT lesion is frequently required late after TAP repair. There is no consensus for the best technique for TAP repair even in the current era. The optimal design of the patch, patch material, and reconstruction technique for the best long-term preservation of RVOT function should be explored in the future.
