RESUMEN
BACKGROUND: The relationship between high postprocedural mean gradient (ppMG) and clinical events following mitral valve transcatheter edge-to-edge repair (MV-TEER) in patients with degenerative mitral regurgitation (DMR) is still debated. AIM: The purpose of this study was to evaluate the effect of elevated ppMG after MV-TEER on clinical events in patients with DMR at 1-year follow-up. METHODS: The study included 371 patients with DMR treated with MV-TEER enrolled in the "Multi-center Italian Society of Interventional Cardiology (GISE) registry of trans-catheter treatment of mitral valve regurgitation" (GIOTTO) registry. Patients were stratified in tertiles according to ppMG. Primary endpoint was a composite of all-cause death and hospitalization due to heart failure at 1-year follow-up. RESULTS: Patients were stratified as follows: 187 with a ppMG ≤ 3 mmHg, 77 with a ppMG > 3/=4 mmHg, and 107 with a ppMG > 4 mmHg. Clinical follow-up was available in all subjects. At multivariate analysis, neither a ppMG > 4 mmHg nor a ppMG ≥ 5 mmHg were independently associated with the outcome. Notably, the risk of elevated residual MR (rMR > 2+) was significantly higher in patients belonging to the highest tertile of ppMG (p = 0.009). The association of ppMG > 4 mmHg and rMR ≥ 2+ was strongly and independently associated with adverse events (hazard ratio: 1.98; 95% confidence interval: [1.10-3.58]). CONCLUSIONS: In a real-world cohort of patients suffering DMR and treated with MV-TEER, isolated ppMG was not associated with the outcome at 1-year follow-up. A high proportion of patients showed both elevated ppMG and rMR and their combination appeared to be a strong predictor of adverse events.

INTRODUCTION: The Watchman-FLX left atrial appendage closure (LAAC) device presents innovative features: higher conformability, reduced length, closed distal "flex-ball" during deployment, and flattened surface. We report our real-world experience with the Watchman-FLX device in two centers with consolidated LAAC expertise. METHODS: We enrolled 200 consecutive Watchman-FLX patients (2019-2021) in a nonrandomized double-center registry; procedural data and follow-up for midterm clinical outcomes were collected. A control group of 100 patients treated with first-generation Watchman (2.5) was included. RESULTS: According to mean CHAD2 DS2 -VASc (5 ± 1.40) and HAS-BLED (3.8 ± 1.01) scores, the population included in this study was at high risk: 29% had a previous stroke and 56.5% a bleeding event. Main LAAC indications were symptomatic hemorrhage (39.5%), need for triple antithrombotic therapy (39%), gastrointestinal bleeding (32%), and oral anticoagulation intolerance (18%). Transesophageal echocardiography guidance was followed in 93% of cases (48% in general anesthesia and 45% under conscious sedation). Repositioning an FLX device was required in 20% of cases and no complication occurred. In 96% of patients, the first selected device was delivered, while in 4% a device size change was required after the first choice (7% with Watchman 2.5). Peridevice leaks (<5 mm) were found postimplant in two cases (1%). Overall, the procedural success rate was 99.5%. One patient's procedure was unsuccessful (0.5%), due to left atrial appendage (LAA) anatomy; differently, the mean failure rate with Watchman 2.5 was 2%. No device embolization was reported. Complications (8.5%) were mainly related to the access site (3%); major bleedings (1%), and in-hospital death (0.5%) rarely occurred. After a follow-up of 272 ± 173 days, 2.3% of cases experienced a non-device-related stroke and 0.6% fatal bleeding. CONCLUSION: Our registry showed a high procedural success rate of the Watchman-FLX in a high-risk population. According to our experience, the main advantages include easy implanting and repositioning, absence of embolization, good LAA sealing, and low rate of complications in the follow-up period.

RESUMEN
BACKGROUND: Mitral-valve transcatheter edge-to-edge repair (MV-TEER) is recommended in patients with severe functional mitral regurgitation (FMR) and in those with degenerative mitral regurgitation (DMR) not eligible to traditional surgery. Patients with a history of previous cardiac surgery are considered at high risk for surgical reintervention, but data are lacking regarding procedural and clinical outcomes. OBJECTIVE: aim of this study was to assess the efficacy and clinical results of MV-TEER in patients with previous cardiac surgery enrolled in the "multicentre Italian Society of Interventional Cardiology registry of transcatheter treatment of mitral valve regurgitation" (GIOTTO). METHODS: Patients with previous coronary artery bypass grafting (CABG), surgical aortic valve replacement (AVR), or mitral valve repair (MVR) were included. Those with multiple or combined previous cardiac surgeries were excluded. Clinical follow-up was performed at 30 days, 1 year, and 2 years. The primary endpoint was a composite of death or rehospitalization at 1- and 2-year follow-ups. RESULTS: A total of 330 patients enrolled in the GIOTTO registry were considered (CABG 77.9%, AVR 14.2%, and MVR 7.9%). Most patients showed FMR (66.9%), moderate reduction of left ventricular (LV) ejection fraction, and signs of LV dilation. Procedural and device successes were 94.8% and 97%. At 1 and 2 years, the composite endpoint occurred are 29.1% and 52.4%, respectively. The composite outcome rates were similar across the three subgroups of previous cardiac surgery (p = 0.928) and between the FMR and DMR subgroups (p = 0.850) at 2 years. In a multivariate analysis, residual mitral regurgitation (rMR) ≥2+ was the main predictor of adverse events at 1 year (hazard ratio: 1.54 [95% confidence interval, CI: 1.00-2.38]; p = 0.050). This association was confirmed at 2 years of Kaplan-Meier analysis (p = 0.001). CONCLUSIONS: MV-TEER is effective in these patients, regardless of the subtype of previous cardiac surgery and the MR etiology. An rMR ≥2+ is independently associated with adverse outcomes at 1-year follow-up.

Limited evidence is available on 5-year clinical outcomes after percutaneous edge-to-edge mitral valve repair. METHODS: The Getting Reduction of mitrAl inSufficiency by Percutaneous clip implantation in ITaly (GRASP-IT) is a multicenter registry including 304 consecutive patients undergoing Mitraclip between October 2008 and October 2013 at 4 Italian centers. Primary end point (all-cause mortality) and secondary end point (all-cause mortality or heart failure [HF] hospitalization) were evaluated up to 5 years and between 1 and 5 years. RESULTS: Cumulative incidence of the primary and secondary end points at 1, 2, 3, 4, and 5â¯years were 15.1%, 26.4%, 35.5%, 42.1%, and 47.3% and 29.1%, 41.7%, 49.8%, 56%, and 62.3%, respectively. Landmark analysis between 1 and 5â¯years showed an incidence of primary and secondary end point of 37.9% and 46.8%, respectively. Five-year event rates were significantly higher in patients with functional ischemic mitral regurgitation (MR) compared to other etiologies. MR recurrence and left ventricular ejection fraction <30% were associated with an increased risk of both primary and secondary end points. EuroSCORE II >5% was associated with an increased risk of 5-year mortality. Ischemic etiology of MR, baseline serum creatinine >1.5â¯mg/dL, chronic obstructive pulmonary disease, and previous HF hospitalizations were independent predictors of 5-year secondary end point. CONCLUSIONS: At 5-year follow-up after Mitraclip, nearly half of patients died and almost two thirds died or were admitted for HF. MR recurrence, ischemic etiology, high comorbidity burden (ie, EuroSCORE II >5%, chronic obstructive pulmonary disease), and advanced cardiomyopathy (ie, left ventricular ejection fraction <30%, prior HF admission, creatinine >1.5â¯mg/dL) significantly increase the relative risk of 5-year clinical events.

OBJECTIVES: This study deals with clinical and echocardiographic outcomes in cardiac resynchronization therapy (CRT) nonresponders patients undergoing Mitraclip procedure. BACKGROUND: Functional mitral regurgitation (FMR) occurs in approximately one-third of heart failure (HF) patients. Resynchronization therapy may correct FMR in patients with HF; however, significant FMR persists in 20-25% of CRT patients. METHODS: All patients included were previously treated with CRT for at least 6 months and remained classified as New York Heart Association (NYHA) functional class III or IV despite optimal medical therapy; the echocardiographic assessment showed lack of decrease of the left ventricular end-systolic volume (LVESV) of at least 10% and residual moderate-to-severe or severe FMR. Clinical and echocardiographic follow-up was scheduled at 1, 3, 6, and 12 months after Mitraclip implantation, and every 6 months thereafter. RESULTS: Thirty patients fulfilled inclusion criteria. Before Mitraclip implantation NYHA class was III in 83% and IV in 17% of patients; after CRT no patient experienced an improvement in FMR. There was a significant improvement in NYHA class from baseline to 6 months, which remained sustained at 12 and 24 months. The degree of FMR significantly improved from baseline to 6 months and from 6 to 12 months. There was left ventricle remodeling with significant reduction of LVESV and an increase of left ventricle ejection fraction at 6 and 12 months, while the opposite trend was noted between 12 and 24 months CONCLUSION: Treatment of moderate to severe FMR in CRT nonresponder is feasible, safe, and reasonably effective in reducing cardiac symptoms.

Percutaneous mitral valve repair (PMVR) with the MitraClip system (Abbott Vascular, Santa Clara, CA, USA) is a valid therapeutic option for patients with severe mitral regurgitation (MR) deemed to be at high or prohibitive surgical risk. Despite the reassuring data on efficacy and long-term durability of the procedure, the proportion of patients with residual or relapsing severe MR after MitraClip therapy is not negligible. In light of the detrimental prognostic impact of severe MR, repeat interventions are increasingly performed in clinical practice using different techniques. In high-risk settings, percutaneous procedures have proven to be effective and safe at reducing MR. Building on this, we sought to summarize the current landscape and clinical experience of reinterventions after failed MitraClip therapy, so as to assist physicians facing the clinical hurdle of proper treatment management after failed PMVR.

We present a case of a patient with severe mitral regurgitation referred to our Institution for an echocardiographic examination as part of the routine workup to assess the eligibility for mitral valve percutaneous repair with either the MitraClip or Cardioband systems. Echocardiography showed the presence of an unusual interatrial membrane in the left atrium that represented a contraindication for the puncture of the interatrial septum. The patient was finally deferred to percutaneous mitral valve replacement using transapical access.

BACKGROUND: There is limited information on the long-term outcomes and prognostic clinical predictors after edge-to-edge transcatheter mitral valve repair with the MitraClip system. METHODS: Consecutive patients with mitral regurgitation (MR) undergoing MitraClip therapy between October 2008 and November 2013 in 4 Italian centers were analyzed. The primary end point of interest was all-cause death. The secondary end point was the composite of all-cause death or rehospitalization for heart failure. RESULTS: A total of 304 patients were included, of which 79% had functional MR and 17% were in New York Heart Association functional class IV. Acute procedural success was obtained in 92% of cases, with no intraprocedural death. The cumulative incidences of all-cause death were 3.4%, 10.8%, and 18.6% at 30 days, 1 year, and 2 years, respectively. The corresponding incidences of the secondary end point were 4.4%, 22.0%, and 39.7%, respectively. In the Cox multivariate model, New York Heart Association functional class IV at baseline and ischemic MR etiology were found to significantly and independently predict both the primary and the secondary end point. A baseline, left ventricular end-systolic volume >110 mL was found to be an independent predictor of the secondary endpoint. Acute procedural success was independently associated with a lower risk of all-cause death and the combination of all-cause death or rehospitalization for heart failure at long-term follow-up. CONCLUSIONS: In a cohort of patients undergoing MitraClip therapy, those presenting at baseline with ischemic functional etiology, severely dilated ventricles, or advanced heart failure and those undergoing unsuccessful procedures carried the worst prognosis.

OBJECTIVES: To assess the influence of patients' gender on the outcomes of percutaneous edge-to-edge mitral valve repair (PMVR) using the MitraClip system. BACKGROUND: Although gender-related differences have been extensively documented in patients who undergo surgery for moderate-to-severe (3+) and severe (4+) mitral regurgitation (MR), studies assessing whether these differences exist after PMVR are lacking. METHODS: Clinical and echocardiographic data through 12-month follow up from 171 consecutive patients whom underwent MitraClip implantation and were dichotomized by the gender (106 males and 65 females) were obtained. The primary safety endpoint was the incidence of major adverse events at 30 days and the primary efficacy endpoint was freedom from death, surgery for mitral valve dysfunction, or grade≥3+ MR at 12-month follow up. RESULTS: The primary safety endpoint was observed in four males (3.8%) and four females (6.2%) (P=0.358). Remarkable reduction in MR postprocedure was revealed in both groups, and these results were mostly sustained. Furthermore, left ventricle reverse remodeling and New York Heart Association (NYHA) functional class improvement were revealed in both groups, but females tended to demonstrate worse results over time (P=0.083). The primary efficacy endpoint obtained by Kaplan-Meier estimates was observed in 76.3 and 70.2%, respectively (log rank P=0.231). CONCLUSIONS: MitraClip implantation in patients with 3+ and 4+ MR is safe and efficacious until mid-term follow up, regardless of patients' gender. Despite improvement in NYHA functional class in both groups, female gender demonstrated a trend toward poorer results. Further validation of our findings is warranted.

OBJECTIVES: We performed systematic optical coherence tomography (OCT) analyses after bioresorbable vascular scaffolds (BVS) implantation in a "real world" setting aiming at evaluating scaffold expansion and longitudinal integrity. BACKGROUND: a comprehensive elucidation of BVS acute performance in the "real-world" setting is lacking. METHODS: acute BVS expansion compared with compliance chart information and longitudinal integrity were assessed in 29 patients (32 lesions) by OCT. In addition, bench experiments with four scaffolds were performed with different combinations of deployment pressures and tube stiffness. RESULTS: scaffold underexpansion, using compliance chart information as reference, was observed in 97% of OCT cross-sections in vivo; however, only 8.3% of the cross-section analyzed revealed BVS area <5 mm(2) . Calcified plaques were more common in the lowest (9.7%) compared with the mid (8.8%) and highest (6.3%) tertiles of scaffold expansion (P = 0.003 and P = 0.001 for lowest vs. mid, and lowest vs. highest, respectively). Seventeen (54.8%) scaffolds were elongated during implantation, but no signs of scaffold fracture were revealed. Elongation and impaired expansion were reproduced in the bench testing when the scaffold was deployed with high pressure in a hard tube. CONCLUSIONS: compliance chart information should not be used to predict final BVS dimensions in the clinical setting. While BVS expansion could be potentially impaired by calcified plaques, they may elongate during deployment. Bench experiments confirmed the elongation phenomenon when BVS were deployed with high pressure in hard tubes.

Transcatheter mitral valve intervention has emerged as an effective treatment option for symptomatic severe mitral regurgitation in patients considered to be inoperable or at high operative risk for surgical mitral valve surgery. Most transcatheter approaches are modifications of existing surgical approaches. Transcatheter edge-to-edge mitral valve repair with the MitraClip system has the largest clinical experience to date, as it offers a sustained clinical benefit in selected patients. This review aims to provide an up-to-date overview of transcatheter mitral valve interventions, including leaflet repair, annuloplasty, and mitral valve implantation.

Percutaneous transluminal angioplasty with or without stent has become the treatment of choice for stenotic lesion in subclavian arteries. However, there is a growing concern following many reports of stent fractures, a serious complication of endovascular therapy. We report for the first time a case of delayed left subclavian stent fracture with transection of the protruding ostial part and migration into the aortic carrefour that was retrieved by a snare device.

BACKGROUND: Numerous reports have shown the relationship between carotid artery atherosclerosis and coronary artery disease (CAD). However, the association between complex CAD evaluated by SYNTAX score (SxScore) and prevalence of carotid lesion (CL) has not been fully investigated. We sought to assess the prevalence of carotid atherosclerosis in patients with multivessel CAD assessed by SxScore and the relationship between SxScore severity and features of carotid atherosclerosis. METHODS AND RESULTS: Subjects were 204 consecutive patients with multivessel CAD assessed by coronary angiography and no previous history of carotid atherosclerosis that underwent carotid ultrasound scan from June 2012 to 2013. Presence of CL, significant carotid disease (SCD) and carotid plaque morphology was evaluated. At least one CL was found in 159 patients (77.9%) with no significant difference among SxScore groups (P = 0.20 and P = 0.54, respectively). High prevalence of complex carotid plaque (CCP) was found without significant different distribution in SxScore groups (P = 0.69). Age was independently associated with the presence of CL [odds ratio (OR) 1.055; 95% confidence interval (CI): 1.015-1.097; P = 0.007] and SCD (OR 1.057; 95% CI: 1.008-1.097; P = 0.019). Age and diabetes were independently associated with CCP (OR 1.58; 95% CI: 1.023-1.095; P = 0.001; OR 1.848; 95% CI: 1.026-3.327; P = 0.041). SxScore was not independently associated with CL, SCD and CCP (all P > 0.2). CONCLUSIONS: We found high prevalence of CL in patients with multivessel complex CAD. However, SxScore does not seem to correlate with carotid atherosclerosis.

AIM: This analysis aimed to compare the clinical outcomes associated with heart failure (HF) readmissions and to identify associations with HF hospitalizations (HFH) in patients treated with the MitraClip™ NTR/XTR System in the EXPAND study. METHODS AND RESULTS: The global, real-world EXPAND study enrolled 1041 patients with primary or secondary mitral regurgitation (MR) treated with the MitraClip NTR/XTR System. Echocardiograms were analysed by an independent echocardiographic core laboratory. The study population was stratified into HFH and No-HFH groups based on the occurrence of HFH 1 year post-index procedure. Clinical outcomes including MR severity, New York Heart Association (NYHA) functional class, Kansas City Cardiomyopathy Questionnaire (KCCQ) score, and all-cause mortality were compared (HFH: n = 181; No-HFH: n = 860). Both groups achieved consistent 1-year MR reduction to ≤1+ (HFH vs. No-HFH: 87.3% vs. 89.5%, p = 0.6) and significant 1-year improvement in KCCQ scores (+16.5 vs. +22.3, p = 0.09) and NYHA functional class. However, more patients in the No-HFH group had 1-year NYHA class ≤II (HFH vs. No-HFH: 67.9% vs. 81.9%, p < 0.01). All-cause mortality at 1 year was 36.8% in the HFH group versus 10.4% in the No-HFH group (p < 0.001). The HFH rate decreased by 63% at 1 year post-M-TEER versus 1 year pre-treatment (relative risk 0.4, p < 0.001). Independent HFH associations were MR ≥2+ at discharge, HFH 1 year prior to treatment, baseline NYHA class ≥III, baseline tricuspid regurgitation ≥2+, and baseline left ventricular ejection fraction ≤40%. CONCLUSIONS: This study reports the impact of HFH on clinical outcomes post-treatment in the EXPAND study. Results demonstrate that the occurrence of HFH was associated with worse 1-year survival, and treatment with the MitraClip system substantially reduced HFH and improved patient symptoms and quality of life.

Left atrial appendage closure (LAAC) is a crucial intervention for stroke prevention in patients with non-valvular atrial fibrillation who are unsuitable for long-term anticoagulation. Amulet and Watchman are the most implanted devices worldwide for performing LAAC, and the aim of this review is to provide a comprehensive comparison focusing on their efficacy, safety, and short- and long-term outcomes. The Watchman device, the first to gain FDA approval, has been extensively studied and demonstrates significant reductions in stroke and systemic embolism rates. The Amulet device, a newer alternative, promises enhanced design features for more efficient appendage sealing. Current data highlight that both devices offer similar efficacy and safety for LAAC. While the two devices differ in terms of intraprocedural complication rates, they offer similar short- to long-term outcomes in terms of peri-device leaks, device-related thrombosis, and mortality. Both devices are indicated for patients who are unable to tolerate OAC, given their similar risk and safety profiles. Newer clinical studies are directed at establishing the efficacy of both devices as the primary method for stroke prevention in AF as an alternative to OAC.
RESUMEN
Atrial functional mitral regurgitation (aFMR) has a peculiar pathophysiology that may have distinctive outcomes. We investigated the impact of transcatheter edge-to-edge repair in aFMR compared with other FMR etiologies. The GIOTTO (GIse registry Of Transcatheter treatment of MR) is a multicenter, prospective study enrolling patients with symptomatic MR treated with MitraClip up to 2020. We categorized patients with FMR as aFMR, ischemic FMR (iFMR), and nonischemic ventricular FMR (niFMR). The clinical end points were defined according to the Mitral Valve Academic Research Consortium. Of 1,153 patients, 6% had aFMR, 47% iFMR, and 47% niFMR. Patients with aFMR were older, mostly women, and had a higher atrial fibrillation rate. They had better left ventricular ejection fraction and smaller left ventricular volumes, with no difference in mitral effective regurgitant orifice area. The acute device and procedural success rates were similar among the groups. At the longest available follow-up (median 478 days, interquartile range 91 to 741 days), the rate of MR ≥2+ was similar among the groups. Patients with aFMR had a lower rate of cardiovascular death and heart failure than patients with iFMR (hazard ratio [HR] 0.43, p = 0.02) and niFMR (HR 0.45, p = 0.03). The aFMR etiology remained independently associated with the composite outcome, together with postprocedural MR ≤1+ (HR 0.63, p <0.01) and peripheral arteriopathy (HR 1.82, p = 0.003). The results of this GIOTTO subanalysis suggested that aFMR is less prevalent and associated with better outcomes compared with other causes of FMR treated by transcatheter edge-to-edge repair. Postprocedural MR >1+, peripheral vasculopathy, non-aFMR were independent predictors of worse outcomes.

Introduction: Recent studies have shown gender differences in cardiovascular outcomes after left atrial appendage closure (LAAC), highlighting different complication rates and adverse events, particularly in short-term assessments. As a result, there remains a significant knowledge gap on how these differences directly impact the efficacy and safety of LAAC procedures. The aim of this retrospective study was to investigate the clinical outcomes of LAAC in women and men using the Watchman FLX device. Methods: This retrospective, multicenter study analyzes gender-specific outcomes in 650 patients who underwent LAAC with the Watchman FLX device between March 2019 and May 2022, drawn from the ITALIAN-FLX registry. Results: The results show comparable rates of all-cause mortality, stroke, transient ischemic attack and major bleeding in men and women 12 months after the procedure. Notably, no significant gender differences were found for periprocedural complications. Conclusion: In conclusion, this study shows that LAAC with the Watchman FLX device has comparable clinical outcomes between genders at both short-term and long-term follow-up.
RESUMEN
BACKGROUND: To assess the interaction between heart failure (HF) severity and optimal reduction of secondary mitral regurgitation (SMR) on mortality in patients undergoing transcatheter edge-to-edge repair (M-TEER). METHODS AND RESULTS: Among 1656 patients included in the Italian Society of Interventional Cardiology (GIse) registry Of Transcatheter treatment of mitral valve regurgitaTiOn (GIOTTO) 984 had SMR and complete data on advanced HF. Advanced HF was defined as NYHA class III or IV, left ventricular ejection fraction ≤ 30%, and > 1 HF hospitalization during the last 12 months. Optimal M-TEER was defined as residual SMR ≤ 1 + at discharge. One hundred sixteen patients (11.8%) had advanced HF. Achievement of an optimal SMR reduction was similar in patients with and without advanced HF (65% and 60% respectively). Advanced HF was an independent predictor of 2-year all-cause death (adjusted HR 1.52, 95% CI 1.09-2.10). Optimal M-TEER, as compared to a no-optimal M-TEER, was associated with a reduced risk of death both in patients with advanced (HR 0.55, 95% CI 0.32-0.97; p = 0.039) and no-advanced HF (HR 0.59, 95% CI 0.46-0.78; p < 0.001; p = 0.778 for interaction). CONCLUSIONS: Advanced HF is associated with poor outcome in patients undergoing M-TEER. However, an optimal SMR reduction reduces the risk of 2-year mortality regardless of HF severity.
