Article Synopsis
- The study examines the outcomes of mitral transcatheter edge-to-edge repair (TEER) performed during off-hours (before 7:30 am, after 5:30 pm, or on weekends/holidays) to see how they compare to procedures done during regular hours.
- The analysis included 1,177 procedures, with 117 (9.9%) occurring off-hours; off-hours procedures were often urgent and involved higher-risk patients, yet technical success was high in both groups.
- Although baseline MR severity and functional class improved for both groups, off-hours patients experienced higher rates of deaths and heart failure hospitalizations, with no procedural timing linked to outcomes in matched comparisons, suggesting experienced interventionalists can conduct these procedures safely regardless
Background: Prognostically meaningful tricuspid regurgitation (TR) is not well-defined in the mitral transcatheter edge-to-edge repair arena. We aimed to explore the prevalence, correlates, and consequences of TR grades and postprocedural trends in this setting.
Methods And Results: A single-center registry of isolated, first-time interventions was retrospectively assessed for pre-, intra-, and postprocedural aspects up to 1 year, of them the primary composite outcome of all-cause deaths or heart failure (HF) hospitalizations, all according to TR severity at baseline and at 1 month following mitral transcatheter edge-to-edge repair.
Background: Research on the role of transcatheter heart valve (THV) deformation and calcium distribution in patients with bicuspid aortic valves (BAVs) undergoing transcatheter aortic valve replacement (TAVR) remains limited.
Objectives: The aim of this study was to evaluate the impact of THV deformation on clinical outcomes in individuals with BAVs undergoing TAVR and the influence of calcium on these outcomes.
Methods: In total, 229 consecutive patients with BAVs who underwent TAVR with balloon-expandable valves and had computed tomography (CT) performed 30 days post-TAVR were analyzed.
Background: The number of successfully recanalized total occlusions affects hemodynamic improvement after balloon pulmonary angioplasty (BPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). We aimed to clarify the current efficacy, patency, and success rate of BPA for total occlusions.
Methods: Between April 2016 and August 2021, 178 BPAs were performed in 100 patients with CTEPH and total occlusions.
Comparison between cryoballoon and hot balloon ablation in patients with paroxysmal atrial fibrillation.

Purpose: Pulmonary vein (PV) isolation using balloon ablation was developed as a technique for patients with paroxysmal atrial fibrillation (PAF). While most studies examined cryoballoon ablation (CBA), there have also been many reports on hot balloon ablation (HBA). We aimed to evaluate the clinical characteristics and outcomes between HBA and CBA.

The ratio of oxHDL to apolipoprotein A-I (oxHDL/apoAI) is a possible marker of dysfunctional HDL. The aim of this study was to evaluate the association between oxHDL/apoAI and coronary plaque characteristics that increase the likelihood of cardiovascular events as determined by coronary computed tomography (CT) angiography.

Recent Findings: Recent advances in coronary CTA have allowed identification of high-risk coronary features in acute coronary syndrome and measurement of changes in the coronary plaque burden with good reproducibility. Statin therapy may delay plaque progression and change some plaque features.
