Aims To evaluate the burden of tricuspid regurgitation (TR) in a large cohort, determine the right ventricle involvement of patients with TR and determine the characteristics of isolated TR. Methods and results Prospective study where consecutive patients undergoing an echocardiographic study in 10 centres were included. All studies with significant TR (at least moderate) were selected. We considered that patients with one of pulmonary systolic hypertension >50 mmHg, left ventricular ejection fraction <35%, New York Heart Association III–IV, or older than 85 years, had a high surgical risk. A total of 35 088 echocardiograms were performed. Significant TR was detected in 6% of studies. Moderate TR was found in 69.6%, severe in 25.5%, massive in 3.9%, and torrential in 1.0% of patients. Right ventricle was dilated in 81.7% of patients with massive/torrential TR, in 55.9% with severe TR, and in 29.3% with moderate TR (P < 0.001). Primary TR was present in 7.4% of patients whereas secondary TR was present in 92.6%. Mitral or aortic valve disease was the most common aetiology (54.6%), following by isolated TR (16%). Up to 51.9% of patients with severe, massive, or torrential primary TR and 57% of patients with severe, massive, or torrential secondary TR had a high surgical risk. Conclusion Significant TR is a prevalent condition and a high proportion of these patients have an indication for valve intervention. More than a half of patients with severe, massive, or torrential TR had a high surgical risk. Massive/torrential TR may have implications regarding selection and monitoring patients for percutaneous treatment.
Functional mitral regurgitation (MR) could be defined as a ventricular disease where mitral valve is structurally normal, left chambers are enlarged and mitral annulus is dilated with lack of coaptation of leaflets. Transcatheter mitral valve repair technique has broadened the therapeutic range in the treatment of severe MR. The aim of this study was to review outcomes of MitraClip vs. medical treatment for functional MR. We also planned to review the concept of functional MR, assessment of the degree, prognosis and therapy options. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The Medline through PubMed database was used to search. The present review included manuscripts published between January 2009 and September 2019. Two authors independently screened titles and abstracts of all publications, and performed the selection of studies and data extraction. In the case of disagreements, consensus meetings reached the final decision. Inclusion criteria were: (I) randomized controlled trials and (II) works must compare MitraClip versus optimal medical treatment. Transcatheter mitral valve repair along optimal medical treatment has been compared with optimal medical therapy in two different randomized trials. In the COAPT trial, the MitraClip group showed a significant reduction in mortality and heart failure (HF) hospitalizations. In the MITRA-FR trial, no significant differences were observed between both groups. We reviewed important aspects of functional MR and performed a comprehensive review of both trials comparing them and focusing on their differences.
Background: Functional mitral regurgitation (FMR) is a bad prognosis condition despite optimal medical treatment. Nowadays there is an open debate about the surgical versus percutaneous treatment. The main objective of this study is to evaluate the mid-term follow up clinical outcomes of patients with FMR treated with MitraClip ® system, according to their left ventricular ejection fraction (LVEF).Methods: Data was obtained from two experienced centers in transcatheter mitral valve repair (TMVR).All consecutive cases of severe FMR undergoing TMVR in both centers with the same inclusion criteria were included prospectively in this study and followed-up. Periodical follow-ups with clinical and echocardiographic evaluation were scheduled from the baseline procedure, at 3 months and then yearly.Results: From October 2015 to October 2019, a total of 119 patients with FMR at 2 centers in Spain underwent TMVR with the MitraClip ® procedure and were included in this study. The mean age was 73.8±8.9 years old and 32 patients (26.9%) were female. A 39.5% of cases [47] had a LVEF ≤30% (group 1) and 60.5% (72 cases) had a LVEF >30% (group 2). There was a similar distribution in cardiovascular risk factors, age and other diseases. All MitraClip ® implantations were elective and procedural success was achieved in 110 patients (92.4%) with a similar distribution between the groups. There were no differences in procedural time and the number of implanted clips. The median follow-up was 22.6 months (IQR, 11.43-34.98 months). The primary combined endpoint occurred in the 41.6% of the global cohort, 57.5% in group 1 and 30.99% in group 2 (P=0.036). LVEF was associated to the main event in the multivariate analysis (HR 2.09, 95% CI: 1.12-3.89; P=0.02). Conclusions:The MitraClip edge-to-edge technique is a safe and effective procedure for the treatment of FMR. In this study, patients with LVEF >30% treated with Mitraclip presented better clinical cardiovascular outcomes than those with a LVEF ≤30%. Regardless clinical outcomes, at the end of the follow-up, there was a sustained reduction in MR grades and an important improvement in NYHA functional class.
Sodium-glucose cotransporter-2 inhibitors (SGLT-2 inhibitors) are new glucose-lowering drugs (GLDs) with demonstrated cardiovascular benefits in patients with heart disease and type-2 diabetes mellitus (T2DM). However, their safety and efficacy when prescribed at hospital discharge are unexplored. This prospective, observational, longitudinal cohort study included 104 consecutive T2DM patients discharged from the cardiology department between April 2018 and February 2019. Patients were classified based on SGLT-2 inhibitor prescription and adjusted by propensity-score matching. The safety outcomes included discontinuation of GLDs; worsening renal function; and renal, hepatic, or metabolic hospitalization. The efficacy outcomes were death from any cause, cardiovascular death, cardiovascular readmission, and combined clinical outcome (cardiovascular death or readmission). The results showed that, the incidence rates of safety outcomes were similar in the SGLT-2 inhibitor or non-SGLT-2 inhibitor groups. Regarding efficacy, the SGLT-2 inhibitors group resulted in a lower rate of combined clinical outcomes (18% vs. 42%; hazard ratio (HR), 0.35; p = 0.02), any cause death (0% vs. 24%; HR, 0.79; p = 0.001) and cardiovascular death (0% vs. 17%; HR, 0.83; p = 0.005). No significant differences were found in cardiovascular readmissions. SGLT-2 inhibitor prescription at hospital discharge in patients with heart disease and T2DM was safe, well tolerated, and associated with a reduction in all-cause and cardiovascular deaths.
