Outcomes After Initial Unifocalization to a Shunt in Complex Tetralogy of Fallot With MAPCAs
Bauser-Heaton and colleagues evaluated outcomes for patients with complex tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs), focusing on those patients who underwent unifocalization with placement of a shut rather than simultaneous intracardiac repair. Between 2001 and 2017, 57 patients underwent this type of procedure at the authors’ center. In this high-risk cohort, complete repair was achieved in 67% of patients within 3 years. The median right ventricle to systemic pressure ratio for patients with complete repair was 0.4.
