• W2564486094 abstract "Right ventricular dysfunction (RVdy) is negatively associated with survival after left heart valve surgery. It is unclear whether RVdy has the same impact in patients undergoing transcatheter aortic valve implantation (TAVI). We sought to evaluate the prognostic impact of different grades of RVdy on TAVI, with and without concomitant left ventricular dysfunction (LVdy), and the possible impact of TAVI on RVdy.Among 870 consecutive patients with severe symptomatic aortic stenosis undergoing TAVI, 226 patients (26%) presented with a concomitant diagnosis of RVdy. Patients were divided into three groups, Group 1: normal RV systolic function, i.e., tricuspid annular plane systolic excursion (TAPSE) >16 mm (n=644, 74%); Group 2: mild-to-moderate RVdy, i.e., TAPSE 10-16 mm (n=180, 20.6%); Group 3: severe RVdy, i.e., TAPSE <10 mm (n=46, 5.2%). Patients in Groups 1 and 2 showed a similar overall mortality rate at one month (5% vs. 8%, OR 1.1 [0.7-1.55], p=0.2) and at one-year follow-up (15% vs. 19%, HR 1.5 [0.84-2.2], p=0.09), respectively. Compared to Groups 1 and 2, patients in Group 3 showed a significantly higher overall mortality at one month (22%, OR 3.3 [1.8-4.1], p<0.001, and OR 2.1 [1.7-3.1], p=0.02, respectively) as well as at one-year follow-up (45%, HR 2.6 [2.1-3.45], p<0.001, and HR 1.9 [1.5-2.7], p=0.02), respectively. Pulmonary hypertension >60 mmHg (HR 1.5 [1.1-2.2], p=0.03), AF (HR 1.6 [1.1-2.4], p=0.01), creatinine clearance <30 mL/min (HR 1.92 [1.3-2.5], p=0.003), LVEF <30% (HR 1.5 [1.1-2.9], p=0.03), severe RVdy (HR 2.9 [2.7-3.3], p=0.002), severe RV dilation (HR 1.7 [1.2-2.2], p=0.005) and severe biventricular dysfunction (HR 3.9 [2.7-4.1], p=0.002) were independent predictors of one-year mortality. Among survivors, the majority of patients in Groups 2 and 3 experienced a significant improvement in NYHA class.Severe RVdy limits the expected benefit of TAVI. In current risk scores right heart failure is not considered. The present study advocates the evaluation of this strong predictor in a more complete pre-procedural work-up." @default.
