Progressive right ventricular enlargement due to pulmonary regurgitation: Clinical characteristics of a “low-risk” group

The optimal interval between serial cardiac magnetic resonance imaging (CMRI) scans for monitoring right ventricular (RV) enlargement in the setting of severe pulmonic valve regurgitation (PR) is unknown. The purposes of this study were to (1) determine the annual change in RV volume on serial CMRI scans and (2) identify the risk factors for rapid progression of RV enlargement.A retrospective study of adults with postintervention native valve PR...
