Increased pulmonary artery pressures during exercise are related to persistent tricuspid regurgitation after atrial septal defect closure

Although closure of an atrial septal defect type secundum often normalizes right heart dimensions and pressures, mild tricuspid insufficiency might persist. This study aimed at (1) identification of determinants explaining the persistence of tricuspid insufficiency after atrial septal defect closure, and (2) evaluation of functional capacity of patients with persistent mild tricuspid insufficiency.status: publishe
