MDCT of Partial Anomalous Pulmonary Venous Return (PAPVR) in Adults

Abstract

This represents the largest and only consecutive retrospective study of PAPVR in adults to date. Left upper lobe PAPVR was the most frequent location detected on MDCT, whereas RUL PAPVR was slightly less common and moderately associated with sinus venosus ASD. Utilization of contrast-enhanced studies and MDCT technology has enabled improved detection and characterization of PAPVR for early diagnosis and/or intervention.
