B This article refers to 'Italian Society of Interventional Cardiology (GIse) registry Of Transcatheter treatment of mitral valve regurgitaTiOn (GIOTTO): impact of valve disease aetiology and residual mitral regurgitation after MitraClip implantation' by F. Bedogni I et al i ., published in this issue on pages 1364-1376. b Mitral regurgitation (MR) is the most frequent heart valve disease in the community and the second most frequent cause of hospital referral.1-3 The distinction between primary and secondary MR is of utmost importance since they differ not only in the mechanism causing valve failure but also in their prevalence, prognosis and treatment. While the reduced risk of death associated with a grade 1+ residual MR was expected for primary MR, in which left ventricular dysfunction is the consequence of MR, this is less obvious for secondary MR, in which MR is not the cause but the consequence of left ventricular dysfunction. In this study, in both primary and secondary MR, a grade 1+ residual MR was a protective factor for 1-year mortality and patients with grade 3+/4+ residual MR were at high risk of early death (within 60 days) with 50% of deaths at 1 year.

Aims: The MITRA-FR trial showed that among symptomatic patients with severe secondary mitral regurgitation, percutaneous repair did not reduce the risk of death or hospitalization for heart failure at 12 months compared with guideline-directed medical treatment alone. We report the 24-month outcome from this trial.Methods and Results: At 37 centres, we randomly assigned 304 symptomatic heart failure patients with severe secondary mitral regurgitation (effective regurgitant orifice area >20 mm2 or regurgitant volume >30 mL), and left ventricular ejection fraction between 15% and 40% to undergo percutaneous valve repair plus medical treatment (intervention group, n = 152) or medical treatment alone (control group, n = 152). The primary efficacy outcome was the composite of all-cause death and unplanned hospitalization for heart failure at 12 months. At 24 months, all-cause death and unplanned hospitalization for heart failure occurred in 63.8% of patients (97/152) in the intervention group and 67.1% (102/152) in the control group [hazard ratio (HR) 1.01, 95% confidence interval (CI) 0.77-1.34]. All-cause mortality occurred in 34.9% of patients (53/152) in the intervention group and 34.2% (52/152) in the control group (HR 1.02, 95% CI 0.70-1.50). Unplanned hospitalization for heart failure occurred in 55.9% of patients (85/152) in the intervention group and 61.8% (94/152) in the control group (HR 0.97, 95% CI 0.72-1.30).Conclusions: In patients with severe secondary mitral regurgitation, percutaneous repair added to medical treatment did not significantly reduce the risk of death or hospitalization for heart failure at 2 years compared with medical treatment alone.

Aims: Tricuspid regurgitation (TR) is commonly observed in patients with severe left‐sided valvular heart disease (VHD). This study sought to assess TR frequency, management and outcome in this population. Methods and results: Among 6883 patients with severe native left‐sided VHD or previous left‐sided valvular intervention enrolled in the EURObservational Research Programme prospective VHD II survey, moderate or severe TR was very frequent in patients with severe mitral VHD (30% when mitral stenosis, 36% when mitral regurgitation [MR]), especially in patients with secondary MR (46%), and rare in patients with severe aortic VHD (4% when aortic stenosis, 3% when aortic regurgitation). An increase in TR grade was associated with a more severe clinical presentation and a poorer 6‐month survival (p < 0.0001). Rates of concomitant tricuspid valve (TV) intervention at the time of left‐sided heart valve surgery were high at the time of mitral valve surgery (50% when mitral stenosis, 41% when MR). Concordance between class I indications (patients with severe TR) for concomitant TV surgery at the time of left‐sided valvular heart surgery according to guidelines and real‐practice decision‐making was very good (88% overall, 95% in patients operated on for MR). Conclusion: In this large international prospective survey among patients with severe left‐sided VHD, moderate/severe TR was frequent in patients with mitral valve disease and was associated with a poorer outcome as TR grade increased. In patients with severe TR, compliance to guidelines for class I indications for concomitant TV surgery at the time of left‐sided heart valve surgery was very good. [ABSTRACT FROM AUTHOR]

Aim: Mitral regurgitation (MR) and tricuspid regurgitation (TR) are common in patients with heart failure (HF). The aim of this study was to investigate prevalence, clinical characteristics and outcomes of patients with or without isolated or combined MR and TR across the entire HF spectrum. Methods and results: The ESC‐HFA EORP HF Long‐Term Registry is a prospective, multicentre, observational study including patients with HF and 1‐year follow‐up data. Outpatients without aortic valve disease were included and stratified according to isolated or combined moderate/severe MR and TR. Among 11 298 patients, 7541 (67%) had no MR/TR, 1931 (17%) isolated MR, 616 (5.5%) isolated TR and 1210 (11%) combined MR/TR. Baseline characteristics were differently distributed across MR/TR categories. Compared to HF with reduced ejection fraction, HF with mildly reduced ejection fraction was associated with a lower risk of isolated MR (odds ratio [OR] 0.69; 95% confidence interval [CI] 0.60–0.80), and distinctly lower risk of combined MR/TR (OR 0.51; 95% CI 0.41–0.62). HF with preserved ejection fraction (HFpEF) was associated with a distinctly lower risk of isolated MR (OR 0.42; 95% CI 0.36–0.49), and combined MR/TR (OR 0.59; 95% 0.50–0.70), but a distinctly increased risk of isolated TR (OR 1.94; 95% CI 1.61–2.33). All‐cause death, cardiovascular death, HF hospitalization and combined outcomes occurred more frequently in combined MR/TR, isolated TR and isolated MR versus no MR/TR. The highest incident rates were observed in isolated TR and combined MR/TR. Conclusion: In a large cohort of outpatients with HF, prevalence of isolated and combined MR and TR was relatively high. Isolated TR was driven by HFpEF and was burdened by an unexpectedly poor outcome. [ABSTRACT FROM AUTHOR]

Aims: To evaluate the current management and survival of patients with left‐sided infective endocarditis (IE) complicated by congestive heart failure (CHF) in the ESC‐EORP European Endocarditis (EURO‐ENDO) registry. Methods and results: Among the 3116 patients enrolled in this prospective registry, 2449 (mean age: 60 years, 69% male) with left‐sided (native or prosthetic) IE were included in this study. Patients with CHF (n = 698, 28.5%) were older, with more comorbidity and more severe valvular damage (mitro‐aortic involvement, vegetations >10 mm and severe regurgitation/new prosthesis dehiscence) than those without CHF (all p ≤ 0.019). Patients with CHF experienced higher 30‐day and 1‐year mortality than those without (20.5% vs. 9.0% and 36.1% vs. 19.3%, respectively) and CHF remained strongly associated with 30‐day (odds ratio[OR] 2.37, 95% confidence interval [CI] [1.73–3.24; p < 0.001) and 1‐year mortality (hazard ratio [HR] 1.69, 95% CI 1.39–2.05; p < 0.001) after adjustment for established outcome predictors, including early surgery, or after propensity matching for age, sex, and comorbidity (n = 618 [88.5%] for each group, both p < 0.001). Early surgery, performed on 49% of these patients with IE complicated by CHF, remained associated with a substantial reduction in 30‐day mortality following multivariable analysis, after adjustment for age, sex, Charlson comorbidity index, cerebrovascular accident, Staphylococcus aureus IE, streptococcal IE, uncontrolled infection, vegetation size >10 mm, severe valvular regurgitation and/or new prosthetic dehiscence, perivalvular complication, and prosthetic IE (OR 0.22, 95% CI 0.12–0.38; p < 0.001) and in 1‐year mortality (HR 0.29, 95% CI 0.20–0.41; p < 0.001). Conclusion: Congestive heart failure is common in left‐sided IE and is associated with older age, greater comorbidity, more advanced lesions, and markedly higher 30‐day and 1‐year mortality. Early surgery is strongly associated with lower mortality but is performed on only approximately half of patients with CHF, mainly because of a surgical risk considered prohibitive.
