Usefulness of peak frequency in Electrograms for elimination of left atrial Posterior Wall residual potentials via Epicardial connections.

Left atrial posterior wall (LAPW) residual potentials via epicardial connections during LAPW isolation are often low-frequency continuous potentials. Accurate annotation of these residual potentials by three-dimensional electroanatomical mapping systems is challenging and can be misleading. Herein, we present a case of successful LAPW isolation using peak frequency analysis.

Association Between Direct Oral Anticoagulant Score and Bleeding Events in Patients With Atrial Fibrillation Following Transcatheter Aortic Valve Replacement: A Retrospective Multicenter Cohort Study.

Background: The Direct Oral Anticoagulant (DOAC) Score can predict bleeding risk in patients with atrial fibrillation taking DOACs; however, it lacks external validation. Therefore, this study aimed to assess the association between the DOAC Score and bleeding events in patients with atrial fibrillation who underwent transcatheter aortic valve replacement.

Methods And Results: This retrospective multicenter cohort study included patients with atrial fibrillation who underwent transcatheter aortic valve replacement, as registered in a Japanese multicenter registry.

Clinical Impact of Baseline Frailty Status and Residual Mitral Regurgitation After Transcatheter Edge-to-Edge Repair: Insights From the OCEAN-Mitral Registry.

Background: The Clinical Frailty Scale (CFS) is a useful frailty marker for predicting clinical outcomes in patients undergoing invasive therapy. However, the clinical impact of CFS after transcatheter edge-to-edge repair in patients with mitral regurgitation (MR) remains unclear. This study aimed to elucidate the association between the baseline frail status defined by the CFS and clinical outcomes with or without postprocedural MR ≥2+ (post-MR ≥2+) after transcatheter edge-to-edge repair.

One-Year Outcomes and Their Relationship to Residual Mitral Regurgitation After Transcatheter Edge-to-Edge Repair With MitraClip Device: Insights From the OCEAN-Mitral Registry.

Background Limited data are available about clinical outcomes and residual mitral regurgitation (MR) after transcatheter edge-to-edge repair in the large Asian-Pacific cohort. Methods and Results From the Optimized Catheter Valvular Intervention (OCEAN-Mitral) registry, a total of 2150 patients (primary cause of 34.6%) undergoing transcatheter edge-to-edge repair were analyzed and classified into 3 groups according to the residual MR severity at discharge: MR 0+/1+, 2+, and 3+/4+.

Influence of Sex on Relationship Between Total Anatomical and Physiologic Disease Burdens and Their Prognostic Implications in Patients With Coronary Artery Disease.

Background Total atherosclerosis disease burden is associated with clinical outcomes in patients with coronary artery disease. However, the influence of sex on the relationship between total anatomical and physiologic disease burdens and their prognostic implications have not been well defined. Methods and Results A total of 1136 patients who underwent fractional flow reserve (FFR) measurement in all 3 major coronary arteries were included in this study.
