Objective: Societal guidelines recommend vitamin K antagonists (VKAs) for atrial fibrillation patients with recent biological valve implantation, but the safety and efficacy of direct oral anticoagulants (DOACs) in this setting remain uncertain, especially in the early postoperative period. This substudy of the Left Atrial Appendage Occlusion Study (LAAOS) III trial aimed to compare thromboembolic and bleeding outcomes in patients discharged on VKAs versus DOACs after bioprosthesis implantation or mitral valve repair.
Methods: A total of 2,645 patients were included, with 461 discharged on DOACs and 2184 on VKAs.

Objectives: This study explores the impact of lower baseline aortic valve (AV) mean gradients on the clinical outcomes of patients with low-gradient aortic stenosis (LG AS) post-transcatheter aortic valve replacement (TAVR). Additionally, the study aims to understand the predictors of a lower baseline AV mean gradient (MG).
Background: Reduced left ventricular ejection fraction (LVEF) and low-flow states are known to correlate with worse clinical outcomes.

Left atrial appendage (LAA) closure has emerged as a critical therapeutic option for stroke prevention in patients with atrial fibrillation who are unsuitable for long-term oral anticoagulation. Multimodality imaging plays a pivotal role throughout the LAA closure process, from pre-procedural planning to long-term follow-up. This review focuses on the complementary roles of cardiac computed tomography (CCT) and transesophageal echocardiography (TEE), outlining their respective strengths and limitations in various phases of LAA management, while also discussing the roles of intracardiac echocardiography (ICE) and fluoroscopy.

We report the first use of the EnSite X system for intraoperative electrophysiological mapping during a robotic hybrid ablation (ROK-AF procedure) for long-standing persistent atrial fibrillation. Epicardial ablation targets were identified, and post-ablation electrical silencing was validated. Unlike conventional systems, its orientation-independent omnipolar technology provides directional activation vectors, high-resolution electrograms, and peak frequency analysis, thereby enhancing substrate characterisation.
