No other disclosures exist.Background: The Watchman FLX is a device upgrade of the Watchman 2.5 that incorporates several design enhancements intended to simplify left atrial appendage occlusion (LAAO) and improve procedural outcomes. This study compares peri-procedural results of LAAO with Watchman FLX (Boston Scientific, Marlborough, Massachusetts) in centers with varying degrees of experience with the Watchman 2.5 and Watchman FLX. Methods: Prospective, multicenter, “real-world” registry including consecutive patients undergoing LAAO with the Watchman FLX at 26 Spanish sites (FLX-SPA registry). Implanting centers were classified according to the center's prior experience with the Watchman 2.5. A further division of centers according to whether or not they had performed ≤ 10 or > 10Watchman FLX implants was prespecified at the beginning of the study. Procedural outcomes of institutions stratified according to their experience with the Watchman 2.5 and FLX devices were compared. Results: 359 patients [mean age 75.5 (SD8.1), CHA2DS2-VASc 4.4 (SD1.4), HAS-BLED 3.8(SD0.9)] were included. Global success rate was 98.6%, successful LAAO with the first selected device size was achieved in 95.5% patients and the device was implanted at first attempt in 78.6% cases. There were only 9(2.5%) major peri-procedural complications. No differences in efficacy or safety results according to the centeŕs previous experience with Watchman 2.5 and procedural volume with Watchman FLX existed. Conclusions: The Watchman FLX attains high procedural success rates with complete LAA sealing in unselected, real-world patients, along with a low incidence of peri-procedural complications, regardless of operatoŕs experience with its previous device iteration or the number of Watchman FLX devices implanted.Gerencia Regional Salud de CyL GRS 3031/A/19Boston Scientific CorporationEuropean Regional Development FundInstituto de Salud Carlos III PI19/0065

    Percutaneous left atrial appendage occlusion in the current practice

    Oral anticoagulation (OAC) is the standard of care for stroke prevention in atrial fibrillation, but it is associated with a substantial risk of bleeding complications and its effect depends on optimal patient ́s compliance. In patients with nonvalvular atrial fibrillation, the left atrial appendage is the source of thrombi that may cause stroke in up to 91% to 95% of cases. Thus, percutaneous left atrial appendage occlusion (LAAO) is being increasingly performed as an alternative to OAC for stroke prophylaxis in patients at increased bleeding risk. The current evidence supporting LAAO derives from 3 randomized controlled trials: 2 on Watchman device use in patients eligible for short‑term OAC and a more recent trial comparing LAAO with Amulet and Watchman device use versus long‑term OAC with direct oral anticoagulants (DOACs). In addition, numerous real‑life registries have reported favorable outcomes with Watchman, ACP, and Amulet devices in patients at higher bleeding risk and / or formal contraindications to short‑term OAC, employing less intensive antithrombotic regimens after LAAO. Furthermore, there has been growing evidence on newer devices with distinct features that might be of value to specific subgroups of patients. However, several issues remain unresolved including optimal patient and device selection, individual tailoring of postprocedural antithrombotic therapy, and management of periprocedural complications such as device‑related thrombus and residual peridevice leaks. Finally, the relative benefit of LAAO versus DOACs should be further assessed across the spectrum of patient candidacy for DOACs, over extended follow‑up periods. In this article, we review the body of evidence supporting LAAO with currently available devices

    BACKGROUND The real-world outcomes of the use of the BASILICA (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction) transcatheter technique in Europe have not been described. AIMS We sought to evaluate the procedural and one-year outcomes of BASILICA in patients at high risk for coronary artery obstruction (CAO) undergoing transcatheter aortic valve implantation (TAVI) in a multicentre European registry (EURO-BASILICA). METHODS Seventy-six patients undergoing BASILICA and TAVI at ten European centres were included. Eighty-five leaflets were identified as targets for BASILICA due to high risk for CAO. The updated Valve Academic Research Consortium 3 (VARC-3) definitions were used to determine prespecified endpoints of technical and procedural success and adverse events up to one year. RESULTS Treated aortic valves included native (5.3%), surgical bioprosthetic (92.1%) and transcatheter valves (2.6%). Double BASILICA (for both left and right coronary cusps) was performed in 11.8% of patients. Technical success with BASILICA was achieved in 97.7% and resulted in freedom from any target leaflet-related CAO in 90.6% with a low rate of complete CAO (2.4%). Target leaflet-related CAO occurred significantly more often in older and stentless bioprosthetic valves and with higher implantation levels of transcatheter heart valves. Procedural success was 88.2%, and freedom from VARC-3-defined early safety endpoints was 79.0%. One-year survival was 84.2%; 90.5% of patients were in New York Heart Association Functional Class I/II. CONCLUSIONS EURO-BASILICA is the first multicentre study evaluating the BASILICA technique in Europe. The technique appeared feasible and effective in preventing TAVI-induced CAO, and one-year clinical outcomes were favourable. The residual risk for CAO requires further study

    Background: Right ventricular (RV) to pulmonary circulation (PC) coupling can stratify prognosis in heart failure (HF). In this study, we assessed the prognostic role of the mean velocity of the pulmonary artery (mvPA) determined by cardiac magnetic resonance (CMR) in HF with preserved ejection fraction (HFpEF). Methods: Inclusion of 58 HFpEF outpatients that underwent CMR with measurement of RV–PC coupling parameters including mvPA between 2016 and 2019. The primary combined endpoint was a composite of HF readmissions and all-cause mortality. Results: Optimal cut-off value of mvPA calculated by receiver operating curve for the prediction of the primary endpoint was 9 cm/s. Over a median follow-up of 23 months (interquartile range: 24), 21 patients met the primary endpoint. The primary endpoint was more frequent in patients with mvPA ≤ 9 cm/s, as indicated by Kaplan–Meier survival curves; Log-Rank: 9.193, p = 0.02, regardless of RV dysfunction. On Cox multivariate analysis, mvPA ≤ 9 cm/s emerged as an independent prognostic predictor of the primary endpoint (HR: 4.11, 95% CI: 1.28–13.19, p = 0.017), together with left atrial area by CMR (HR: 1.08, 95% CI: 1.01–1.24, p = 0.034). Conclusions: In our HFpEF cohort, mvPA was associated with a higher rate of the primary endpoint, regardless of RV function, thus enabling identification of patients at higher risk of cardiovascular events before structural damage onset
