Abstract

OBJECTIVES: This study was designed to assess hemodynamic changes in response to transcatheter tricuspid valve edge-to-edge repair (TTVR) and to identify hemodynamic predictors associated with mortality.
BACKGROUND: Severe tricuspid regurgitation (TR) is associated with high mortality. TTVR effectively alleviates heart failure symptoms, but comprehensive hemodynamic characterization of patients undergoing TTVR is currently lacking.
METHODS: This international, multicenter study included 236 patients undergoing TTVR. Data from clinical assessment, echocardiography, intraprocedural right heart catheterization, and noninvasive cardiac output measurement were analyzed. Hemodynamic predictors for mortality were identified using linear Cox regression analysis and were used for stratification of patients with subsequent analysis of survival time.
RESULTS: Patients (median age 78 years, 53% women) were symptomatic (89% in New York Heart Association functional class III or IV) because of severe TR (grade ≥3+ in 100%). TTVR significantly reduced TR at discharge (grade ≥3+ in 16%; p < 0.001), with a corresponding 19% reduction of the right atrial v wave (21 mm Hg vs. 16 mm Hg; p < 0.001) and an improvement in cardiac output (from 3.5 to 4.0 l/min; p < 0.01). Invasive mean pulmonary artery pressure, transpulmonary gradient, pulmonary vascular resistance, and right ventricular stroke work were significant predictors of 1-year mortality (p < 0.05 for all). Hemodynamic stratification by mean pulmonary artery pressure and transpulmonary gradient best predicted 1-year survival (p < 0.001). Although patients with pre-capillary dominant pulmonary hypertension showed an unfavorable prognosis (1-year survival 38%), patients without or with post-capillary pulmonary hypertension had favorable outcome (1-year survival 92% or 78%, respectively).
CONCLUSIONS: Invasive assessment of cardiopulmonary hemodynamic status predicts survival after TTVR. Invasive hemodynamic characterization may help identify patients profiting most from TTVR.
