Functional Tricuspid Regurgitation After Transcatheter Closure of Atrial Septal Defect in Adult Patients: Long-Term Follow-Up



Functional Tricuspid Regurgitation After Transcatheter Closure of Atrial Septal Defect in Adult Patients: Long-Term Follow-Up



Jacc. Cardiovascular Interventions 10(21): 2211-2218



This study aimed to assess the fate of tricuspid regurgitation (TR) after transcatheter atrial septal defect (ASD) closure. Although TR frequently occurs in patients with ASD, the change in TR during long-term follow-up after ASD closure remains unknown. A total of 419 adult patients who underwent transcatheter ASD closure were enrolled. TR severity was graded by TR jet area on echocardiography. At baseline, 113 patients had severe/moderate TR and 306 patients had mild TR. Among the 113 patients with severe/moderate TR, the TR jet area significantly decreased during a median follow-up of 30 months after the procedure; this decrease was related to the improvement in right ventricular morphology. The severity of TR decreased to mild in 79 (70%) patients. Persistent TR, defined as severe or moderate TR after the procedure, was independently associated with the prevalence of permanent atrial fibrillation. Regarding clinical outcomes, 7 patients with severe/moderate TR and 2 with mild TR were hospitalized because of heart failure. Patients with severe/moderate TR had the worse event-free survival rate than those with mild TR, but more than 90% of them had no cardiovascular events. New York Heart Association functional class and plasma B-type natriuretic peptide levels improved in patients with severe/moderate TR, similar to those with mild TR. Significant TR decreased during the long-term follow-up period after transcatheter ASD closure. Heart failure symptoms improved in patients with severe/moderate TR. Our findings suggest that transcatheter closure alone can be valuable in patients with ASD complicated with TR.
