Background Severe tricuspid regurgitation (TR) should be intervened before the development of irreversible right ventricular (RV) dysfunction. However, current guidelines do not provide criterion related to RV systolic function to guide optimal surgical timing. We investigated the prognostic value of RV longitudinal strain in patients undergoing isolated surgery for severe functional TR. Methods and Results We enrolled 115 consecutive patients (aged 62±10 years; 23.5% men; 62.6% [n=72] with previous left‐sided valve surgery) who underwent isolated surgery for severe functional TR at 2 tertiary centers. Preoperative clinical and echocardiographic parameters, including RV free‐wall longitudinal strain (RVFWSL), were collected. The primary end point was a composite of cardiac death and unplanned readmission attributable to cardiovascular causes 5 years after surgery. Forty patients (34.8%) reached the primary end point during 333 person‐years of follow‐up. There were 11 cardiac deaths and 34 unplanned readmissions attributable to cardiovascular causes, with 5 patients experiencing both. An absolute preoperative RVFWSL <24% was associated with the primary end point (hazard ratio, 2.30; 95% CI, 1.22–4.36; P =0.011), independent of clinical risk factors, including European System for Cardiac Operative Risk Evaluation II and hemoglobin levels. Meanwhile, other conventional echocardiographic measures of RV systolic function were not significant. The addition of an absolute RVFWSL <24% provided incremental prognostic value to the clinical model for predicting the primary end point. Conclusions Preoperative RVFWSL as an indicator of RV dysfunction was an independent prognosticator in patients undergoing isolated surgery for severe functional TR. Thus, preoperative RVFWSL could help determine the optimal surgical timing for severe functional TR.

Abstract Aims Right ventricular systolic dysfunction is considered an outcome predictor in various cardiac diseases, sometimes stronger than ejection fraction (EF). We assume that right ventricular dysfunction, calculated with echocardiography in patients candidate for trans-catheter aortic valve implantation (TAVI), could be an outcome predictor. To evaluate the prognostic value of pre-TAVI right ventricular free wall longitudinal strain (RVFWSL) in patients with severe aortic stenosis undergoing TAVI. Methods and results Retrospective analysis of 100 patients underwent transfemoral TAVI in our hospital from January 2015 to September 2019, with at least a pre-TAVI and post-TAVI echocardiography. For each patients we collected clinical and echo data before and after TAVI and during the follow-up; we measured RVFWSL off-line at the same time. We considered the value of [23.3]% the cut-off of normality for RVFWSL. The primary endpoint was a composite of death from any cause and hospitalization for heart failure. The median age of the patients was 81 years (79–83) and EF was preserved in most patients (median: 56%, 55–58.28%). At a median follow-up of 1023 days (630–1387), the univariate analysis demonstrated a predictive of a reduced RVFWSL before TAVI ( &lt; [23.3]%, P = 0.015) and EF &lt; 50% (P = 0.014). Cox regression analysis found that pre-TAVI reduced RVFWSL (HR: 2.875, CI 95%: 1.113–7.425; P = 0.03) and EF &lt; 50% (HR: 2.511, CI 95%: 1.07–5.892; P = 0.03) were independently associated with composite endpoint of the study. Moreover, a reduced EF associated with RVFWSL &lt; [23.3]% had an incremental value in predicting the outcome (P = 0.021). Conclusions Among patients with severe aortic stenosis undergoing TAVI, a reduced pre-implant RVFWSL is able to predict long-term outcome.
