Red blood cell transfusion and mortality after transcatheter aortic valve implantation via transapical approach: A propensity-matched comparison from the TRITAVI registry.

Objective: Bleeding is frequent during transcatheter aortic valve implantation (TAVI), especially when performed through a transapical approach (TA), and is associated with a worse prognosis. The present study aims to test the implication of red blood cell (RBC) transfusion and the optimal transfusion strategy in this context. Methods: Among 11,265 participants in the multicenter TRITAVI (Transfusion Requirements in Transcatheter Aortic Valve Implantation) registry, 548 patients (4.9%) who received TA-TAVI at 19 European centers were included. One-to-one propensity score matching was performed to reduce treatment selection bias and potential confounding among transfused versus non-transfused patients. The primary endpoint of the study was the 30-day occurrence of all-cause mortality. Results: 209 patients (38 %) received RBC transfusions. The primary endpoint occurred in 47 (8.6 %) patients. Propensity score matching identified 188 pairs of patients with and without RBC transfusion. In the propensity score-matched analysis, RBC transfusion was associated with increased 30-day mortality (HR 3.35, 95 % CI 1.51 - 7.39; p = 0.002). At multivariable cox regression analysis, RBC transfusion was an independent predictor of 30-day mortality (HR 3.07, 95 % CI 1.01-9.41, p = 0.048), as well as baseline ejection fraction (HR 0.96, 95 % CI 0.92-0.99, p = 0.043), and acute kidney injury (HR 3.95, 95 % CI 1.11-14.05, p = 0.034). Conclusions: RBC transfusion is an independent predictor of short-term mortality in patients undergoing TA-TAVI, regardless of major bleeding.Clinical trial registration: https://www.clinicaltrials.gov Unique identifier: NCT03740425.

Application of the Academic Research Consortium High Bleeding Risk criteria in patients treated with coronary bioresorbable polymer everolimus-eluting stents: Insights from the POEM trial.

BACKGROUND: Previous studies have investigated a 1 to 6-month short dual antiplatelet therapy (S-DAPT) after percutaneous coronary intervention (PCI) with modern drug eluting-stents to reduce bleeding events. OBJECTIVES: To investigate cardiovascular outcomes in patients at high bleeding risk (HBR) according to the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria after PCI with the Synergy bioresorbable-polymer everolimus-eluting stents (EES). METHODS: We applied ARC-HBR criteria in the population of the prospective, single-arm, multicenter POEM (Performance of Bioresorbable Polymer-Coated Everolimus-Eluting Synergy Stent in Patients at HBR Undergoing Percutaneous Coronary Revascularization Followed by 1-Month Dual Antiplatelet Therapy) trial. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 12 months. RESULTS: The original POEM cohort included 356 patients (80.4 %) fulfilling ARC-HBR criteria. Oral anticoagulant (OAC) usage and age ≥75 years were the most frequent major and minor ARC-HBR criteria, respectively. The ARC-HBR group was mainly represented by men (71.1 %), with 74.4 ± 9.3 years and a high burden of cardiovascular risk factors. DAPT was prescribed in 79.3 %, and single antiplatelet (SAPT) with OAC in 18.7 %. 12-month follow-up was completed in 96.2 %. The primary endpoint occurred in 5.2 % (95 % CI 3.29-8.10) of patients, whereas bleeding Academic Research Consortium type 3-5 occurred in 2.7 % (95 % CI, 1.39 %-5.05 %). CONCLUSION: Previous results of the POEM trial showed positive outcomes regarding ischemic and bleeding events with an S-DAPT regimen after Synergy EES. These results are also confirmed in sub-group analysis when ARC-HBR criteria are applied.

GLP-1-ra and heart failure-related outcomes in patients with and without history of heart failure: an updated systematic review and meta-analysis.

AIMS: Glucagon-like peptide-1 receptor agonists (GLP1-ra) have shown to reduce cardiovascular (CV) events in patients with diabetes, including heart failure (HF) hospitalizations. However, whether such benefit consistently occurs in patients with history of HF remains uncertain. We performed a systematic review and meta-analysis to assess the impact of GLP1-ra on CV outcomes in patients with and without HF history. METHODS AND RESULTS: All randomized, placebo-controlled trials evaluating GLP1-ra and reporting CV outcomes stratified by HF history were searched in Pubmed from inception to November 12th, 2023. The primary outcome was HF hospitalizations. Secondary outcomes included CV death, the composite of CV death and hospitalizations for HF, and major adverse cardiovascular events (MACE). Hazard ratio (HR) and 95% confidence interval (CIs) were used as effect estimates and calculated with a random-effects model. 68,653 patients (GLP1-ra = 34,301, placebo = 34,352) from 10 trials were included. GLP1-ra reduced HF hospitalization (no HF: HR = 0.79, 95% CI 0.63-0.98; HF: HR = 1.00, 95% CI 0.82-1.24, pinteraction = 0.12), CV death (no HF: HR = 0.81, 95% CI 0.71-0.92; HF: HR = 0.97, 95% CI 0.81-1.15, pinteraction = 0.11), and the composite of HF hospitalizations and CV death (no HF: HR = 0.80, 95% CI 0.72-0.89; HF: HR = 1.00 95% CI 0.88-1.15, pinteraction = 0.010) only in patients without history of HF, despite a significant interaction between HF history and treatment effect was detected only for the latter. MACE were reduced in both subgroups without significant interaction between HF history and treatment effect (no HF: HR = 0.86, 95% CI 0.78-0.96; HF: HR = 0.83, 95% CI 0.72-0.95, pinteraction = 0.69). CONCLUSION: GLP1-ra do not decrease HF-hospitalization risk, despite a potential benefit in patients without history of HF, but are effective in reducing ischemic events irrespective of the presence of HF.

On the necessity to include arterial pre-stress in patient-specific simulations of minimally invasive procedures.

Transcatheter aortic valve implantation (TAVI) and thoracic endovascular aortic repair (TEVAR) are minimally invasive procedures for treating aortic valves and diseases. Finite element simulations have proven to be valuable tools in predicting device-related complications. In the literature, the inclusion of aortic pre-stress has not been widely investigated. It plays a crucial role in determining the biomechanical response of the vessel and the device-tissue interaction. This study aims at demonstrating how and when to include the aortic pre-stress in patient-specific TAVI and TEVAR simulations. A percutaneous aortic valve and a stent-graft were implanted in aortic models reconstructed from patient-specific CT scans. Two scenarios for each patient were compared, i.e., including and neglecting the wall pre-stress. The neglection of pre-stress underestimates the contact pressure of 48% and 55%, the aorta stresses of 162% and 157%, the aorta strains of 77% and 21% for TAVI and TEVAR models, respectively. The stent stresses are higher than 48% with the pre-stressed aorta in TAVI simulations; while, similar results are obtained in TEVAR cases. The distance between the device and the aorta is similar with and without pre-stress. The inclusion of the aortic wall pre-stress has the capability to give a better representation of the biomechanical behavior of the arterial tissues and the implanted device. It is suggested to include this effect in patient-specific simulations replicating the procedures.

Clinical and procedural outcomes of percutaneous coronary intervention for de novo lesions involving the ostial left circumflex coronary artery.

BACKGROUND: Percutaneous treatment for ostial left circumflex artery (LCx) lesions is known to be associated with suboptimal results. AIMS: The present study aims to assess the procedural and long-term clinical outcomes of percutaneous coronary intervention (PCI) for de novo ostial LCx lesions overall and according to the coronary revascularization strategy. METHODS: Consecutive patients undergoing PCI with second generation drug eluting stents or drug coated balloons for de novo ostial LCx lesions in three high-volume Italian centers between 2012 and 2021 were retrospectively evaluated. The primary endpoint was target-vessel revascularization (TVR) at 2 years. Secondary endpoints included major adverse cardiovascular and cerebrovascular events (MACCE), target lesion revascularization, myocardial infarction, stroke, all-cause death, and repeat revascularization. RESULTS: A total of 366 patients were included in the analysis with a median follow-up of 901 (IQR: 450-1728) days. 79.5% of the patients were male, 33.6% were diabetic, 49.7% had a previous PCI, and 23.1% a prior surgical revascularization. Very ostial LCx stenting was performed in 34.1%, crossover from left main to LCx in 17.3%, and a two-stent strategy in 48.6% of cases, respectively. In the overall population, the incidence of TVR at 2 years was 19.0% while MACCE rate was 25.7%. No major differences in clinical outcomes were found according to the stenting strategy. Use of intracoronary imaging was associated with fewer MACCE (HR: 0.47, 95% CI: 0.25-1.13, p = 0.01), while the diameter of the stent implanted in the ostial LCx was associated with less TVR (HR: 0.43, 95% CI: 0.25-0.75, p = 0.002). CONCLUSIONS: Percutaneous revascularization of the ostial LCx is associated with a high rate of TVR, regardless of the stenting strategy. Intracoronary imaging and proper stent sizing may reduce the failure rates.

Dyspnea-Related Ticagrelor Discontinuation After Percutaneous Coronary Intervention.

BACKGROUND: Nearly 20% of patients on ticagrelor experience dyspnea, which may lead to treatment discontinuation in up to one-third of cases. OBJECTIVES: The authors sought to evaluate the incidence, predictors, and outcomes of dyspnea-related ticagrelor discontinuation after percutaneous coronary intervention (PCI). METHODS: In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. The occurrence of dyspnea associated with ticagrelor discontinuation was evaluated among all patients enrolled in the trial. A landmark analysis was performed at 3 months after PCI, that is, the time of randomization. Predictors of dyspnea-related ticagrelor discontinuation were obtained from multivariable Cox regression with stepwise selection of candidate variables. RESULTS: The incidence of dyspnea-related ticagrelor discontinuation was 6.4% and 9.1% at 3 and 15 months after PCI, respectively. Independent predictors included Asian race (lower risk), smoking, prior PCI, hypercholesterolemia, prior coronary artery bypass, peripheral artery disease, obesity, and older age. Among 179 patients who discontinued ticagrelor because of dyspnea after randomization, ticagrelor monotherapy was not associated with a higher risk of subsequent ischemic events (composite of all-cause death, myocardial infarction, or stroke) compared with ticagrelor plus aspirin (5.0% vs 7.1%; P = 0.566). CONCLUSIONS: In the TWILIGHT trial, dyspnea-related ticagrelor discontinuation occurred in almost 1 in 10 patients and tended to occur earlier rather than late after PCI. Several demographic and clinical conditions predicted its occurrence, and their assessment may help identify subjects at risk for therapy nonadherence.

Drug-Coated Balloon Angioplasty for De Novo Lesions on the Left Anterior Descending Artery.

BACKGROUND: Drug-coated balloons (DCB) are an emerging tool for modern percutaneous coronary intervention (PCI), but evidence on their use for de novo lesions on large vessels is limited. METHODS: Consecutive patients undergoing DCB-based PCI on the left anterior descending artery in 2 Italian centers from 2018 to 2022 were retrospectively enrolled and compared with patients who received left anterior descending PCI with contemporary drug-eluting stents (DES). In-stent restenosis was excluded. The DCB group included both patients undergoing DCB-only PCI and those receiving hybrid PCI with DCB and DES combined. The primary end point was target lesion failure at 2 years, defined as the composite of target lesion revascularization, cardiac death, and target vessel myocardial infarction. RESULTS: We included 147 consecutive patients undergoing DCB-based treatment on the left anterior descending artery and compared them to 701 patients who received conventional PCI with DES. In the DCB group, 43 patients (29.2%) were treated with DCB only and 104 (70.8%) with a hybrid approach; DCB length was greater than stent length in 55.1% of cases. Total treated length was higher in the DCB group (65 [40-82] versus 56 [46-66] mm; P=0.002), while longer DESs were implanted (38 [24-62] versus 56 [46-66] mm; P<0.001) and a higher rate of large vessels were treated (76.2% versus 83.5%; P=0.036) in the DES cohort. The cumulative 2-year target lesion failure incidence was not significantly different between the 2 groups (DCB, 4.1% versus DES, 9.8%; hazard ratio, 0.51 [95% CI, 0.20-1.27]; P=0.15). After a 1:1 propensity score matching resulting in 139 matched pairs, the DCB-based treatment was associated with a lower risk for target lesion failure at 2 years compared with DES-only PCI (hazard ratio, 0.2 [95% CI, 0.07-0.58]; P=0.003), mainly driven by less target lesion revascularization. CONCLUSIONS: A DCB-based treatment approach for left anterior descending revascularization allows a significantly reduced stent burden, thereby potentially limiting target lesion failure risk at midterm follow-up.

Rationale and design of the PARTHENOPE trial: A two-by-two factorial comparison of polymer-free vs biodegradable-polymer drug-eluting stents and personalized vs standard duration of dual antiplatelet therapy in all-comers undergoing PCI.

BACKGROUND: Over the past few decades, percutaneous coronary intervention (PCI) has undergone significant advancements as a result of the combination of device-based and drug-based therapies. These iterations have led to the development of polymer-free drug-eluting stents. However, there is a scarcity of data regarding their clinical performance. Furthermore, while various risk scores have been proposed to determine the optimal duration of dual antiplatelet therapy (DAPT), none of them have undergone prospective validation within the context of randomized trials. DESIGN: The PARTHENOPE trial is a phase IV, prospective, randomized, multicenter, investigator-initiated, assessor-blind study being conducted at 14 centers in Italy (NCT04135989). It includes 2,107 all-comers patients with minimal exclusion criteria, randomly assigned in a 2-by-2 design to receive either the Cre8 amphilimus-eluting stent or the SYNERGY everolimus-eluting stent, along with either a personalized or standard duration of DAPT. Personalized DAPT duration is determined by the DAPT score, which accounts for both bleeding and ischemic risks. Patients with a DAPT score <2 (indicating higher bleeding than ischemic risk) receive DAPT for 3 or 6 months for chronic or acute coronary syndrome, respectively, while patients with a DAPT score ≥2 (indicating higher ischemic than bleeding risk) receive DAPT for 24 months. Patients in the standard DAPT group receive DAPT for 12 months. The trial aims to establish the noninferiority between stents with respect to a device-oriented composite end point of cardiovascular death, target-vessel myocardial infarction, or clinically-driven target-lesion revascularization at 12 months after PCI. Additionally, the trial aims to demonstrate the superiority of personalized DAPT compared to a standard approach with respect to a net clinical composite of all-cause death, any myocardial infarction, stroke, urgent target-vessel revascularization, or type 2 to 5 bleeding according to the Bleeding Academic Research Consortium criteria at 24-months after PCI. SUMMARY: The PARTHENOPE trial is the largest randomized trial investigating the efficacy and safety of a polymer-free DES with a reservoir technology for drug-release and the first trial evaluating a personalized duration of DAPT based on the DAPT score. The study results will provide novel insights into the optimizing the use of drug-eluting stents and DAPT in patients undergoing PCI.

Transcatheter interventions for left-sided valvular heart disease complicated by cardiogenic shock: a consensus statement from the European Association of Percutaneous Cardiovascular Interventions (EAPCI) in collaboration with the Association for Acute Cardiovascular Care (ACVC) and the ESC Working Group on Cardiovascular Surgery.

Valvular heart disease (VHD) is one of the most frequent causes of heart failure (HF) and is associated with poor prognosis, particularly among patients with conservative management. The development and improvement of catheter-based VHD interventions have broadened the indications for transcatheter valve interventions from inoperable/high-risk patients to younger/lower-risk patients. Cardiogenic shock (CS) associated with severe VHD is a clinical condition with a very high risk of mortality for which surgical treatment is often deemed a prohibitive risk. Transcatheter valve interventions might be a promising alternative in this setting given that they are less invasive. However, supportive scientific evidence is scarce and often limited to small case series. Current guidelines on VHD do not contain specific recommendations on how to manage patients with both VHD and CS. The purpose of this clinical consensus statement, developed by a group of international experts invited by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) Scientific Documents and Initiatives Committee, is to perform a review of the available scientific evidence on the management of CS associated with left-sided VHD and to provide a rationale and practical approach for the application of transcatheter valve interventions in this specific clinical setting.

Long-term prognostic impact of subclinical myocardial dysfunction in patients recovered from COVID-19.

BACKGROUND: Cardiovascular sequelae may occur in patients recovered from coronavirus disease 2019 (COVID-19). Recent studies have detected a considerable incidence of subclinical myocardial dysfunction-assessed with speckle-tracking echocardiography-and of long-COVID symptoms in these patients. This study aimed to define the long-term prognostic role of subclinical myocardial dysfunction and long-COVID condition in patients recovered from COVID-19 pneumonia. METHODS: We prospectively followed up 110 patients hospitalized at our institution due to COVID-19 pneumonia in April 2020 and then recovered from SARS-CoV-2 infection. A 7-month clinical and echocardiographic evaluation was performed, followed by a 21-month clinical follow-up. The primary outcome was major adverse cardiovascular events (MACE), a composite of myocardial infarction, stroke, heart failure hospitalization, and all-cause mortality. RESULTS: A subclinical myocardial dysfunction-defined as an impairment of left ventricular global longitudinal strain (≥-18%)-was identified at a 7-month follow-up in 37 patients (34%), was associated with an increased risk of long-term MACE with a good discriminative power (area under the curve: .73) and resulted in a strong independent predictor of extended MACE in multivariate regression analyses. Long-COVID condition was not associated with a worse long-term prognosis, instead. CONCLUSIONS: In patients recovered from COVID-19 pneumonia, a subclinical myocardial dysfunction is present in one-third of the whole population at 7-month follow-up and is associated with a higher risk of MACE at long-term follow-up. Speckle-tracking echocardiography is a promising tool to optimize the risk-stratification in patients recovered from COVID-19 pneumonia, while the definition of a long-COVID condition has no prognostic relevance.

Stent Thrombosis and Restenosis with Contemporary Drug-Eluting Stents: Predictors and Current Evidence.

Iterations in stent technologies, advances in pharmacotherapy, and awareness of the implications of implantation techniques have markedly reduced the risk of stent failure, both in the form of stent thrombosis (ST) and in-stent restenosis (ISR). However, given the number of percutaneous coronary interventions (PCI) performed worldwide every year, ST and ISR, albeit occurring at a fairly low rate, represent a public health problem even with contemporary DES platforms. The understanding of mechanisms and risk factors for these two PCI complications has been of fundamental importance for the parallel evolution of stent technologies. Risk factors associated with ST and ISR are usually divided into patient-, lesion-, device- and procedure-related. A number of studies have shown how certain risk factors are related to early (1 month) versus late/very late ST (between 1 month and 1 year and >1 year, respectively). However, more research is required to conclusively show the role of time-dependence of risk factors also in the incidence of ISR (early [1 year] or late [>1 year]). A thorough risk assessment is required due to the complex etiology of ST and ISR. The most effective strategy to treat ST and ISR is still to prevent them; hence, it is crucial to identify patient-, lesion-, device- and procedure-related predictors.

The emerging role of sodium-glucose cotransporter 2 inhibitors in heart failure.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are a relatively novel drug class that most cardiologists are becoming familiar with. By contrasting glucose reabsorption in the proximal convoluted tubule of the nephron, SGLT2 inhibition results in glycosuria with improved glycemic control. Although originally introduced as anti-diabetic medications, the cardiovascular effects of SGLT2i have progressively emerged, leading them to become one of the four pillars for the treatment of heart failure with reduced ejection fraction (HFrEF) according to the 2021 guidelines from the European Society of Cardiology. Also, two recent randomized trials have demonstrated SGLT2i as the first compound with proven prognostic impact in heart failure with preserved ejection fraction (HFpEF), setting a milestone in the treatment for this condition. While the exact pathogenic mechanisms mediating the substantial reduction in cardiovascular death and heart failure (HF) hospitalizations are still controversial, there is growing clinical evidence on the efficacy and safety of SGLT2i in various subsets of patients with HF. As known, heart failure is a complex and heterogeneous clinical syndrome with a magnitude of phenotypes and a variety of underlying hemodynamic and physiological aspects which cannot be fully incorporated into the traditional left ventricular ejection fraction based classification adopted in clinical trials. The aim of this review is to provide an overview of the cardiovascular benefits and indications of SGLT2i across different HF patterns and to highlight current gaps in knowledge that should be addressed by future research.

P2Y12 Inhibitors Monotherapy in Patients Undergoing Complex vs Non-Complex Percutaneous Coronary Intervention: A Meta-Analysis of Randomized Trials.

BACKGROUND: Monotherapy with P2Y12 inhibitors (P2Y12i) is emerging as alternative strategy to dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). However, early withdrawal of aspirin as part of P2Y12i monotherapy regimens may pose concerns in high-risk patients, such as those undergoing complex PCI. Our aim was to evaluate the efficacy and safety of P2Y12i monotherapy after a short course of DAPT (1-3-month) compared with standard DAPT (≥12-month) according to PCI complexity. METHODS: We performed a meta-analysis of randomized trials using random effects models to combine hazard ratios (HRs) with 95% confidence intervals (CIs). Within-trial interactions were pooled to estimate heterogeneity between complex and noncomplex PCI strata. The study protocol was registered in the PROSPERO (CRD42021291027). RESULTS: We identified 5 trials including 31,627 patients, of whom 8,328 (26.3%) underwent complex PCI. P2Y12i monotherapy compared with standard DAPT was associated with a similar risk of all-cause death, stent thrombosis, and stroke, with no evidence for interaction between complex and noncomplex PCI. We found heterogeneity in the treatment effect of P2Y12i monotherapy vs standard DAPT with respect to myocardial infarction (P-interaction = 0.027). Compared with standard DAPT, P2Y12i monotherapy decreased the risk of myocardial infarction in complex PCI (HR 0.77, 95%CI 0.60-0.99, P = .042), but not in noncomplex PCI patients (HR 1.09, 95%CI 0.90-1.30, P = .382). The risk of major bleeding was significantly reduced by P2Y12i monotherapy with a consistent treatment effect (P-interaction = 0.699) in both complex and noncomplex PCI strata. CONCLUSIONS: Patients undergoing complex PCI may derive more benefit and less harm from P2Y12i monotherapy after early aspirin withdrawal compared with standard DAPT.

Antiplatelet Strategies Following PCI: A Review of Trials Informing Current and Future Therapies.

Dual antiplatelet therapy (DAPT) has been paramount in preventing thrombosis following percutaneous coronary intervention for nearly 3 decades. However, over the years, DAPT has seen significant changes in the agents utilized and duration of therapy as trials have raced to keep up with advancements made in stent technology and our understanding of bleeding and ischemic risk. Recently, there have been a number of trials demonstrating significant reductions in bleeding events with shorter DAPT durations, which are not yet reflected in practice guidelines. Further, there has been a shift toward more individualized antiplatelet regimens to meet patient-specific risk profiles. This review provides a comprehensive summary of the major trials that have informed current DAPT strategies, puts into context recent trials driving a shift toward more tailored antiplatelet regimens, and highlights gaps in knowledge that remain and the ongoing trials designed to address them.

Left Ventricular Thrombus Management After Acute Myocardial Infarction in Clinical Practice: Results from LEVITATION Survey and Narrative Review.

PURPOSE: Left ventricular thrombus (LVT) after ST-elevation myocardial infarction still presents diagnostic and therapeutic challenges. The LEVITATION survey was designed to take a picture of LVT management in current clinical practice. METHODS: The survey covered diagnostic, therapeutic, and prophylactic issues and was completed by 104 European cardiac centers. Most of them (59%) were university or tertiary centers. RESULTS: The survey showed anterior apical a-/dyskinesia, large MI, spontaneous echo-contrast, late presentation with delayed PCI, and TIMI flow 0-1 as the most important perceived risk factors for LVT formation. Serial ultrasound imaging is the most used tool to diagnose LVT (88% of the centers), with contrast-enhanced ultrasound and cardiac MR performed in case of poor apex visualization or spontaneous echo-contrast. One third (34%) of the centers uses prophylactic anticoagulation to prevent LVT formation. In the presence of LVT, low molecular weight heparin is the most used in-hospital therapy. At discharge, vitamin K antagonist and direct oral anticoagulants are used in 67 and 32% of the cases, respectively. Triple antithrombotic therapy with aspirin plus clopidogrel and VKA is the most used strategy at discharge (55%), whereas a single antiplatelet therapy is preferred only in the case of moderate-to-high risk of bleeding. To assess LVT total regression, half of the centers use contrast-enhanced ultrasound and/or cardiac-MR. The duration of anticoagulation is usually 3-6 months (55%), with long-term prolongation in case of LVT persistence or recurrence. CONCLUSION: The survey has depicted for the first time the current real-world management of this neglected topic and has highlighted several grey zones that are still present and not supported by evidence.

Distal vs Conventional Radial Access for Coronary Angiography and/or Intervention: A Meta-Analysis of Randomized Trials.

BACKGROUND: Emerging evidence from randomized clinical trials (RCTs) comparing distal radial access (DRA) with conventional radial access (RA) is available. OBJECTIVES: The aim of this study was to provide a quantitative appraisal of the effects of DRA) vs conventional RA for coronary angiography with or without intervention. METHODS: The PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for RCT comparing DRA vs conventional RA for coronary angiography and/or intervention. Data were pooled by meta-analysis using a random-effects model. The primary endpoint was radial artery occlusion (RAO) at the longest available follow-up. RESULTS: Fourteen studies enrolling 6,208 participants were included. Compared with conventional RA, DRA was associated with a significant lower risk of RAO, either detected at latest follow-up (risk ratio [RR]: 0.36; 95% CI: 0.23-0.56; P < 0.001; number needed to treat [NNT] = 30) or in-hospital (RR: 0.32; 95% CI: 0.19-0.53; P < 0.001; NNT = 28), as well as EASY (Early Discharge After Transradial Stenting of Coronary Arteries) ≥II hematoma (RR: 0.51; 95% CI: 0.27-0.96; P = 0.04; NNT = 107). By contrast, DRA was associated with a higher risk of access site crossover (RR: 3.08; 95% CI: 1.88-5.06; P < 0.001; NNT = 12), a longer time for radial puncture (standardized mean difference [SMD]: 3.56; 95% CI: 0.96-6.16; P < 0.001), a longer time for sheath insertion (SMD: 0.37; 95% CI: 0.16-0.58; P < 0.001), and a higher number of puncture attempts (SMD: 0.59, 95% CI: 0.48-0.69; P < 0.001). CONCLUSIONS: Compared with conventional RA, DRA is associated with lower risks of RAO and EASY ≥II hematoma but requires longer time for radial artery cannulation and sheath insertion, more puncture attempts, and a higher access site crossover.

Left atrial appendage closure with the II generation Ultraseal device: An international registry. The LIGATE study.

OBJECTIVES: To assess feasibility and safety of second-generation left atrial appendage closure (LAAC) Ultraseal device in patients with nonvalvular atrial fibrillation (NVAF). BACKGROUND: LAAC with first-generation Ultraseal device (Cardia, Eagan, Minnesota) has been shown to be a feasible therapeutic option in patients with NVAF. However, there is a paucity of data regarding the novel second-generation Ultraseal device. METHODS: All patients with NVAF undergoing second-generation Ultraseal device implantation between February 2018 and September 2020 were included in a multicenter international registry. Periprocedural and post-discharge events were collected through 6-month follow-up. Co-primary efficacy endpoints were device success and technical success while primary safety endpoint was in-hospital major adverse event (MAE) occurrence. RESULTS: A total of 52 patients were included: mean age 75 ± 8, 30.8% women, mean HAS-BLED 3 ± 1. The device was successfully implanted in all patients. Technical success was achieved in 50 patients (96.1%). In-hospital MAEs occurred in three patients (5.8%). The incidence of 6-month all-cause death and major bleeding was 11.6% and 2.1%, respectively. No strokes, transient ischemic attacks, systemic embolisms, or device embolization were reported after discharge. CONCLUSIONS: Second-generation Ultraseal device implantation was associated with high success rates and a low incidence of peri-procedural complications. Larger studies with longer follow-up are warranted to further evaluate the safety and the efficacy of this device, especially at long-term follow-up.
