Abstract

Background: Atrial secondary tricuspid regurgitation (A-STR) has been proposed as an important etiologic subentity of secondary tricuspid regurgitation (STR). Patients with A-STR are frequently treated using transcatheter tricuspid valve edge-to-edge repair (T-TEER).

Objectives: The aims of this study were to evaluate prevalence and outcomes following T-TEER for severe A-STR and to compare the results to patients with nonatrial STR.

Methods: The study included patients from the EuroTR (European Registry of Transcatheter Repair for Tricuspid Regurgitation) registry who underwent T-TEER for STR from 2016 until 2022. A-STR was defined as a ratio of end-systolic right atrial area to right ventricular area ≥1.5 in the presence of preserved right ventricular function (tricuspid annular plane systolic excursion >17 mm). The primary study endpoint was 2-year survival free from heart failure hospitalization. Secondary endpoints were 2-year survival, tricuspid regurgitation (TR) reduction at discharge and 1-year follow-up as well as changes in NYHA functional class.

Results: This study included 641 patients (50% women) with a mean age of 79 ± 7 years. The overall prevalence of A-STR was 31% (n = 196). A-STR was associated with a higher prevalence of atrial fibrillation, less frequent comorbidities, better biventricular function, less leaflet tenting, and larger atria. Although TR severity was comparable at baseline, patients with A-STR had more effective procedural TR reduction (TR ≤2+ in 86.9% vs 80.4% of those with nonatrial STR; P = 0.005). Although NYHA functional class improved in both STR subetiologies, the symptomatic burden was lower in patients with A-STR at the latest available follow-up (NYHA functional class ≥III in 46% of patients with nonatrial STR vs 38% in those with A-STR; P = 0.033). Beyond that, A-STR was associated with higher 2-year survival rates free from heart failure hospitalization (66.3% [Q1-Q3: 58.2%-75.5%] vs 47.5% [Q1-Q3: 41.7%-54.7%] in patients with nonatrial STR; P < 0.001). Median survival follow-up was 379 days [Q1-Q3: 155-697 days].

Conclusions: A-STR is a common phenotype of STR and is associated with effective TR reduction and symptomatic reduction after T-TEER.

期刊介绍： JACC: Cardiovascular Interventions is a specialist journal launched by the Journal of the American College of Cardiology (JACC). It covers the entire field of interventional cardiovascular medicine, including cardiac, peripheral, and cerebrovascular interventions. The journal publishes studies that will impact the practice of interventional cardiovascular medicine, including clinical trials, experimental studies, and in-depth discussions by respected experts. To enhance visual understanding, the journal is published both in print and electronically, utilizing the latest technologies.
