The importance of pulmonary regurgitation (PR) after repair of tetralogy of fallot (TOF) is increasingly recognized, but little is known regarding its underlying mechanisms. This phase-contrast cine magnetic resonance (PCMR) study was performed to evaluate the relative contribution of each lung to total regurgitant volume. Forty patients with significant PR underwent a PC MR after repair of TOF.The forward flow in RPA was found to be significantly higher than LPA(53.2 ± 15.6 vs 34.8 ±17.7, P < 0.001), the net flow was higher in RPA than LPA (34.8 ± 17.7 vs 17.9 ± 10.7, P < 0.001), RPA contribution to MPA regurge was higher than LPA (51.6 ± 15.9 vs40.9 ± 18.6, P: 0.047), there was difference in LPA contribution to MPA regurge when age of surgery exceeds 10 years than when age of surgery was less than 10 years (51.7 ±17.1 vs 36.6 ± 17.4, P: 0.016). PR after repair of TOF is commonly associated with differential regurgitation in the branch pulmonaryarteries, although the cause of this disparity requires further investigation, thosepatients with a significant unilateral contribution to total PR may be amenable to localized techniques to reduceregurgitation
