Partial anomalous pulmonary venous return in adults: Insight into pulmonary hypertension.

ABSTRACT:

Background

Partial anomalous pulmonary venous return (PAPVR) is a rare condition that may lead to pulmonary arterial hypertension (PAH). We sought to determine the prevalence of PAPVR, the follow-up rate of incidentally discovered PAPVR, the repercussions of volume and pressure overload on the right ventricle (RV), and the prevalence and predictors of PAH.

Methods and results

Fifty PAPVR patients aged ≥18 years were included. All underwent transthoracic echocardiography and multislice imaging. PAPVR prevalence was 0.2% (23/13,606 chest computed tomography reports). Of the 26 incidentally diagnosed patients, 14 (54%) did not have a cardiac follow-up. Seven (14%) patients had PAH, of whom one third (28%) had Eisenmenger syndrome. The left-to-right shunt ratio (Qp/Qs) was the o
