    L’orientation vers un service adaptĂ© d’un patient admis aux Urgences pour douleur thoracique, motif frĂ©quent et potentiellement grave, est parfois difficile. L’objectif principal de cette Ă©tude Ă©tait de dĂ©terminer quels Ă©taient les facteurs prĂ©dictifs prĂ©coces d’hospitalisation en Cardiologie. MatĂ©riel et mĂ©thodes : Cette Ă©tude prospective, unicentrique, observationnelle a Ă©tĂ© rĂ©alisĂ©e aux Urgences mĂ©dicales du CHU Charles Nicolle de Rouen du 7 octobre au 7 novembre 2013. Les caractĂ©ristiques cliniques et biologiques initiales de tous les patients consĂ©cutifs ayant consultĂ© aux Urgences durant cette pĂ©riode pour une douleur thoracique ont Ă©tĂ© analysĂ©es ainsi que lors de l’évolution hospitaliĂšre. Un suivi clinique tĂ©lĂ©phonique Ă  1 mois a Ă©tĂ© rĂ©alisĂ©. RĂ©sultats : 3402 patients ont consultĂ© aux Urgences durant la pĂ©riode d’inclusion, dont 380 pour une douleur thoracique (11%). La prĂ©sence de facteurs de risque cardiovasculaire (HTA, Surpoids), les caractĂšres typiques de la douleur thoracique (mĂ©dio-thoracique, rĂ©trosternale, constrictive), la prĂ©sence d’anomalies Ă  l’ECG et la prise en charge initiale par le SAMU Ă©taient dĂ©terminants dans l’orientation des patients. Les facteurs cliniques les plus prĂ©dictifs d’une hospitalisation en Cardiologie, en analyse multivariĂ©e, ont Ă©tĂ© inclus dans un score clinique qui pourrait permettre Ă  l’avenir d’aider Ă  une orientation prĂ©coce vers un service de Cardiologie des patients consultant pour une douleur thoracique. Le suivi a mis en Ă©vidence un faible taux d’évĂ©nements parmi les patients pris en charge et aucun dĂ©cĂšs n’a Ă©tĂ© constatĂ© Ă  1 mois chez les patients non hospitalisĂ©s. Conclusion : Les arguments cliniques prĂ©coces Ă©taient dĂ©terminants dans l’orientation d’un patient admis aux Urgences pour douleur thoracique. Un score clinique rapidement utilisable, prĂ©dictif d’hospitalisation en Cardiologie a ainsi pu ĂȘtre Ă©tabli et devra ĂȘtre validĂ© dans le futur. Le suivi Ă  1 mois confirmait la bonne prise en charge initiale des patients aux Urgences avec une absence d’évĂ©nements graves mais mettait en avant un dĂ©ficit de suivi mĂ©dical et de complĂ©ments d’investigation probablement du fait d’un problĂšme de dĂ©mographie mĂ©dicale

    Background The interrelationships between left atrial appendage (LAA) dimensions and device following implantation are unknown. We aimed to analyze the impact of Watchman device implantation on LAA dimensions following its percutaneous closure and potential predictors of remodeling. Methods and Results All consecutive LAA closure procedures performed at 2 centers between November 2017 and December 2020 were included in the WATCH‐DUAL (Watchman 2.5 Versus Watchman FLX in a Dual‐Center Left Atrial Appendage Closure Cohort) registry. This study included patients who had pre‐ and postintervention computed tomography scan analysis. The LAA and device dimensions were measured in a centralized core lab by 3‐dimensional computed tomography scan reconstruction methods, focusing on the device landing zone. This analysis included 104 patients (age, 76.0 [range, 72.0–83.0] years; 72% men; 53% Watchman FLX; 47% Watchman 2.5). The baseline characteristics were comparable between Watchman 2.5 and Watchman FLX groups, except for the higher use of oversizing in the latter group. The median delay for computed tomography control was 49 (range, 43–64) days. The landing zone area (median, 446 [range, 363–523] versus 290 [222–366] mm2; P<0.001) and minimal diameter (median, 23.0 [range, 20.7–24.8] versus 16.7 [14.7–19.4] mm; P<0.001) significantly increased after implantation. The absolute (median, 157 [range, 98–220] versus 85 [18–148] mm2, P<0.001) and relative (median, 50% [range, 32%–79%] versus 26% [4%–50%]; P<0.001) increases in landing zone area were more pronounced in patients with oversized device. Baseline LAA dimensions were smaller, landing zone eccentricity larger, and oversized device more frequent in patients with significant overexpansion compared with the others. Conclusions LAA dimensions increased at the site of the Watchman prosthesis after implantation, suggesting a local positive remodeling after the procedure. This phenomenon was more pronounced in the case of oversized devices

    AIMS No studies have compared Watchman 2.5 (W2.5) with Watchman FLX (FLX) devices to date. We aimed at comparing the FLX with W2.5 devices with respect to clinical outcomes, left atrial appendage (LAA) sealing properties and device-related thrombus (DRT). METHODS AND RESULTS All consecutive left atrial appendage closure (LAAC) procedures performed at two European centres between November 2017 and February 2021 were included. Procedure-related complications and net adverse cardiovascular events (NACE) at 6 months after LAAC were recorded. At 45-day computed tomography (CT) follow-up, intra- (IDL) and peri- (PDL) device leak, residual patent neck area (RPNA), and DRT were assessed by a Corelab. Out of 144 LAAC consecutive procedures, 71 and 73 interventions were performed using W2.5 and FLX devices, respectively. There were no differences in terms of procedure-related complications (4.2% vs. 2.7%, P = 0.626). At 45-day CT, the FLX was associated with lower frequency of IDL [21.3% vs. 40.0%; P = 0.032; odds ratio (OR): 0.375; 95% confidence interval (CI): 0.160-0.876; P = 0.024], similar rate of PDL (29.5% vs. 42.0%; P = 0.170), and smaller RPNA [6 (0-36) vs. 40 (6-115) mm2; P = 0.001; OR: 0.240; 95% CI: 0.100-0.577; P = 0.001] compared with the W2.5 group. At 45 days, rate of DRT as detected by CT and/or transoesophageal echocardiography (TOE), was higher with W2.5 (6.0% vs. 0%, P = 0.045). At 6-month follow-up, NACE did not differ between groups. CONCLUSIONS In this cohort of consecutive LAACs, FLX as compared to W2.5, was associated with similar procedure-related complications and 6-month NACE, but with improved LAA neck coverage, and lower IDL and DRT
