Objective: To compare the outcomes of MitraClip and surgical mitral repair in low-intermediate risk elderly patients affected by degenerative mitral regurgitation (DMR).Methods: We retrospectively selected patients aged !75 years, with Society of Thoracic Surgeons Predicted Risk Of Mortality (STS-PROM) <8%, submitted to MitraClip (n ¼ 100) or isolated surgical repair (n ¼ 206) for DMR at 2 centers between January 2005 and May 2017. To adjust for baseline imbalances, we used a propensity score model for average treatment effect on survival.Results: After weighting, MitraClip showed fewer postoperative complications (P <.05) but increased residual mitral regurgitation (MR) !2 (27.0% vs 2.8%, P <.001) compared with surgery. One-year survival was greater after MitraClip compared with surgery (97.6% vs 95.3%, hazard ratio [HR], 0.09; confidence interval [CI], 0.02-0.37, P ¼ .001), whereas 5-year survival was lower (34.5% vs 82.

Aims To assess the proportion of patients with heart failure and reduced ejection fraction (HFrEF) who are eligible for sacubitril/valsartan (LCZ696) based on the European Medicines Agency/Food and Drug Administration (EMA/FDA) label, the PARADIGM‐HF trial and the 2016 ESC guidelines, and the association between eligibility and outcomes. Methods and results Outpatients with HFrEF in the ESC‐EORP‐HFA Long‐Term Heart Failure (HF‐LT) Registry between March 2011 and November 2013 were considered. Criteria for LCZ696 based on EMA/FDA label, PARADIGM‐HF and ESC guidelines were applied. Of 5443 patients, 2197 and 2373 had complete information for trial and guideline eligibility assessment, and 84%, 12% and 12% met EMA/FDA label, PARADIGM‐HF and guideline criteria, respectively. Absent PARADIGM‐HF criteria were low natriuretic peptides (21%), hyperkalemia (4%), hypotension (7%) and sub‐optimal pharmacotherapy (74%); absent Guidelines criteria were LVEF>35% (23%), insufficient NP levels (30%) and sub‐optimal pharmacotherapy (82%); absent label criteria were absence of symptoms (New York Heart Association class I). When a daily requirement of ACEi/ARB ≥ 10 mg enalapril (instead of ≥ 20 mg) was used, eligibility rose from 12% to 28% based on both PARADIGM‐HF and guidelines. One‐year heart failure hospitalization was higher (12% and 17% vs. 12%) and all‐cause mortality lower (5.3% and 6.5% vs. 7.7%) in registry eligible patients compared to the enalapril arm of PARADIGM‐HF. Conclusions Among outpatients with HFrEF in the ESC‐EORP‐HFA HF‐LT Registry, 84% met label criteria, while only 12% and 28% met PARADIGM‐HF and guideline criteria for LCZ696 if requiring ≥ 20 mg and ≥ 10 mg enalapril, respectively. Registry patients eligible for LCZ696 had greater heart failure hospitalization but lower mortality rates than the PARADIGM‐HF enalapril group.

Objectives To report mid‐term results after MitraClip repair, according to mitral regurgitation (MR) mechanism, in a real‐world single‐center experience. Background Mid‐term outcomes of percutaneous edge‐to‐edge mitral repair in the real world are still limited. Methods We assessed the follow‐up results of patients treated with MitraClip at a single high‐volume mitral center from 2008 to 2016. All patients underwent Heart‐Team discussion, prospective data collection and enrolment in a dedicated outpatient clinic. Functional (FMR, n = 242, 68.6%) and degenerative (DMR, n = 97, 27.5%) MR patients were separately analyzed. Results 5‐Year survival was 53.5 ± 4.5% in FMR vs 57.1 ± 7.5% in DMR (P = 0.087). Reduced survival was strongly associated with worse left ventricle remodeling (ESV HR 1.01, CI 1.01–1.02, P < 0.001) in FMR, and with worse symptoms (New York Heart Association IV HR 6.72, CI 1.78–25.45, P = 0.005) in DMR. 5‐Year cumulative incidence function for MR ≥ 3 was 23.7 ± 3.4% in FMR vs 27.9 ± 5.9% in DMR (P = 0.39), being associated with residual MR = 2 both in FMR (HR 4.67, CI 2.49–8.74, P < 0.001) and DMR (HR 7.15, CI 2.72–18.75, P < 0.001). At 5‐year, patients in NYHA class I‐II increased from 17.9% to 45.3% in FMR (P < 0.001) and from 33.3% to 51.3% in DMR (P < 0.001). Conclusions In this single‐center real‐world experience, 5‐year after MitraClip, half of the patients were alive and 3/4 were free from MR, both in FMR and DMR. Symptoms benefit was sustained in both groups. Advanced ventricular remodeling, advanced symptoms, and suboptimal MR reduction were associated with worse results. Refined patient selection, improved efficacy and more data will be all required to improve long‐term outcomes.

Purpose To evaluate the post-coronavirus disease-19 (COVID-19) outcome of thyroid function in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related thyrotoxicosis. Methods This was a single-center prospective study involving 29 patients (11 females, 18 males; median age 64 years, range: 43-85) with thyrotoxicosis diagnosed after hospitalization for COVID-19 and then followed-up for a median period of 90 days (range: 30-120) after hospital discharge. At follow-up, patients were evaluated for serum thyrotropin (TSH), freethyroxine (FT4), free-triiodiothyronine (FT3), TSH receptor antibodies (TRAb), thyroglobulin antibodies (TgAb), thyroperoxidase antibodies (TPOAb) and ultrasonographic thyroid structure. Results After recovery of COVID-19, serum TSH values significantly increased (P < 0.001) and FT4 values significantly decreased (P = 0.001), without significant change in serum FT3 (P = 0.572). At follow-up, 28 subjects (96.6%) became euthyroid whereas overt hypothyroidism developed in one case. At the ultrasound evaluation of thyroid gland, hypoecogenicity was found in 10 patients (34.5%) and in these cases serum TSH values tended to be higher than those without thyroid hypoecogenity (P = 0.066). All subjects resulted to be negative for TgAb, TPOAb and TRAb. Conclusion In a short-term follow-up, thyroid function spontaneously normalized in most subjects with SARS-CoV-2-related thyrotoxicosis. However, thyroid hypoecogenicity was found in a remarkable number of them and future longer-term studies are needed to clarify whether this ultrasonographic alteration may predispose to develop late-onset thyroid dysfunction.

Background: The neurally mediated syncope (NMS) is sustained by complex cardiac and vascular reflexes, acting on and amplified by central autonomic loops, resulting in bradycardia and hypotension. Hypothesis: Our aim was to assess whether the pathophysiology of NMS is also related to an abnormal peripheral vasoreactivity. Methods: We evaluated by ultrasound the flow-mediated vasodilation (FMD) and the nitrate-mediated dilation (NMD) in 17 patients with NMS, induced by drug-free tilt test in 6 subjects and by nitrate-potentiated tilt test in the other 11 cases; the syncope was classified as vasodepressive (VD) in 8 cases, cardioinhibitory (CI) in 7, and mixed in 2. Results: The FMD was not different from controls (10.2 ± 4.5 vs 11.4 ± 3.9, P = ns), with normal recovery times; the NMD was greater in fainting subjects than in controls (26.7 ± 7.3 vs 19.0 ± 3.6, P < 0.05), with higher values in VD than in CI syncope (31.1 ± 7.0 vs 23.1 ± 5.0, P = ns); compared to controls, subjects with NMS showed normal recovery times after FMD but longer recovery times after nitrate administration (13.0 ± 5.6 vs 6.3 ± 0.7 minutes, P < 0.05). Conclusions:The evaluation of endothelial function supports evidence that NMS is characterized by a marked and sustained endothelial-independent vasodilation, in the presence of a normal FMD; vascular hyperreactivity in response to nitrate administration is particularly overt in vasodepressive syncope and can explain the high rate of responses to nitrate administration during tilt test.
