Predictors of mid-term functional tricuspid regurgitation after device closure of atrial septal defect in adults: Impact of pre-operative tricuspid valve remodeling

摘要

Background: Functional TR occurs in adults with congenital atrial septal defect (ASD) due to left-to-right interatrial shunting and enlarged right heart. The prevalence and the predictors of TR following ASD closure in adults remain unknown. Moreover, whether preoperative anatomical parameters of tricuspid valve related to TR after ASD closure is understudied.
