In patients with severe LV dysfunction undergoing combined CABG and MV repair, restrictive LV diastolic filling pattern is an important preoperative marker of high perioperative mortality rate, further negative remodeling of LV, and progression of mitral regurgitation late after MV repair.

In patients with severe LV dysfunction undergoing CABG, impaired relaxation and pseudonormal pattern of LV diastolic filling correlated with postoperative improvement in LV regional contraction, while restrictive pattern correlated with high early postoperative mortality, morbidity and minimal improvement in LV systolic function. Restrictive LV filling pattern, early diastolic filling deceleration time and LV end-diastolic diameter were found to be independent predictors of perioperative mortality.

The lower TAPSE values are related to higher NYHA functional class, presence of atrial arrhythmias and non-ischaemic aetiology in HF pts. The LVEF, DT of LV filling and RV end-diastolic diameter are independent predictors of reduced TAPSE (< or = 14 mm) in pts with severe systolic LV dysfunction.

Background and Objectives: Cardiac resynchronization therapy (CRT) is a successful treatment option for appropriately selected patients. However, one–third of recipients do not experience any positive outcome or their condition even declines. We aimed to assess preimplantation factors associated with worse survival after the CRT. Materials and Methods: This was a retrospective unicenter trial. The study cohort included 183 consecutive CRT-treated patients. Baseline demographic, clinical, electrocardiographic, and echocardiographic characteristics were analyzed. Results: After the median follow-up of 15.6 months (9.3–26.3), 20 patients had died (11%). In multivariate Cox regression analysis, ischemic origin of heart failure (HF) was a significant predictor of poor survival (adjusted hazard ratio (aHR) 15.235, 95% confidence interval (CI) (1.999–116.1), p = 0.009). In univariate Cox regression, tricuspid annular plane systolic excursion (TAPSE) <15.5 mm (sensitivity 0.824, specificity 0.526; HR 5.019, 95% CI (1.436–17.539), p = 0.012), post-implantation prescribed antiplatelet agents (HR 2.569, 95% CI (1.060–6.226), p = 0.037), statins (HR 2.983, 95% CI (1.146–7.764), p = 0.025), and nitrates (HR 3.694, 95% CI (1.342–10.171), p = 0.011) appeared to be related with adverse outcome. Conclusions: ischemic etiology of HF is a significant factor associated with worse survival after the CRT. Decreased TAPSE is also related to poor survival.

Objectives: To evaluate the impact of concomitant tricuspid valve (TV) repair on the right ventricular (RV) function postoperatively and within the 6 months following degenerative mitral valve (MV) repair. Methods: The prospective study included 37 patients (mean age 57.32 ± 2.13 years) with severe MV regurgitation due to primary MV prolapse. Nineteen underwent successful MV repair (TV(−) group). Additional TV repair due to moderate-to-severe TV regurgitation was performed in 18 (TV(+) group). Two-dimensional (2D) speckle-tracking and tissue Doppler echocardiography was performed for all patients before surgery and 7 days and 6 months after surgery. Results: Preoperative dimensions and indices of RV longitudinal function did not differ between the groups (right ventricle end-diastolic diameter (RVEDD) was 33.53 ± 0.94 mm vs. 34.67 ± 1.72 mm, tricuspid annular systolic motion (S’) was 15.06 ± 0.85 cm/s vs. 16.0 ± 1.27 cm/s, tricuspid annular plane systolic excursion (TAPSE) was 24.02 ± 1.06 mm vs. 22.4 ± 1.36 mm, respectively; p>0.05). RVEDD decreased significantly and did not change within the follow-up in the TV(−) group. In the TV(+) group, RVEDD decreased early after surgery and more markedly six months later in comparison to the TV(−) group. Indices of RV systolic longitudinal function decreased early after surgery and had a tendency to increase after six months in both groups. Regional longitudinal strains of the lateral RV wall decreased early after surgery and improved within the six months in the TV(−) group and did not change significantly in the TV(+) group. Conclusions: Additional TV repair in degenerative MV repair more markedly reduces RV dimensions and does not have a negative impact on RV systolic function in comparison to an isolated MV repair although these conclusions are of limited value due to the lack of a control group.
