Branch Pulmonary Artery Regurgitation in Repaired Tetralogy of Fallot: Correlation with Pulmonary Artery Morphology, Distensibility, and Right Ventricular Function.

ABSTRACT:

Background

The aim was to determine the effect of pulmonary artery (PA) morphology on the branch pulmonary artery-regurgitation fraction (BPA-RF), the relationship of pulmonary insufficiency (PI) to BPA-RF and PA-distensibility, and factors (BPA-RF and PA-distensibility) associated with right ventricular function (RVF) in repaired tetralogy of Fallot (rTOF).

Methods

A total of 182 rTOF patients (median age 17.1 years) were analyzed for length, angle of PA, BPA-RF, PI, and PA-distensibility, using magnetic resonance imaging.

Results

The left PA had a significant greater RF than the right PA (median (interquartile range)): LPA 43.1% (32.6-51.5) and RPA 35.2% (24.7-44.7), p < 0.001. The LPA was shorter with a narrower angle than the RPA (p < 0.001). The ana
