Long-term outcomes of tetralogy of Fallot repair: A 30-year experience with 960 patients

Abstract

Objective: This study evaluates the long-term results of tetralogy of Fallot repair and assesses the risk factors for adverse outcomes. Methods: This retrospective study included 960 patients who underwent transatrial transpulmonary tetralogy of Fallot repair between 1990 and 2020. Results: A transannular patch was placed in 722 patients, and pulmonary valve preservation was achieved in 233 patients. The median age at tetralogy of Fallot repair was 9.4 (interquartile range, 6.2-14.2) months. The median follow-up duration was 10.6 (interquartile range, 5.4-16.3) years. There were 8 early deaths (0.8%) and 20 late deaths (2.1%). Genetic syndrome and pulmonary valve annulus Z score less than −3..
