Timing and characteristics of carotid microembolic signals during pentaspline pulsed field ablation

Mitsuru Takami, Kimitake Imamura, Hidehiro Iwai, Mitsuhiko Shoda et autres

BACKGROUND: Although pulsed field ablation (PFA) is generally considered safe, the mechanisms underlying both symptomatic and silent embolic events remain unclear. OBJECTIVES: This study aimed to investigate the timing, number, size, and characteristics of microembolic signals (MESs) during each step of the …

Predictors of Sinus Rhythm Maintenance After Catheter Ablation in Atrial Fibrillation Patients With Significant Atrial Functional Mitral Regurgitation

Mitsuhiko Shoda, Mitsuru Takami, Kimitake Imamura, Kenichi Tani et autres

Background: Atrial functional mitral regurgitation (FMR) results from left atrial enlargement and dysfunction, typically observed in patients with atrial fibrillation (AF). Predictors of sinus rhythm maintenance after catheter ablation in atrial FMR patients are not well understood. Methods and Results: We retrospectively …

Indication of Implantable Cardioverter Defibrillators for Ventricular Arrhythmias in Coronary Spastic Angina

Kenichi Tani, Mitsuru Takami, Kimitake Imamura, Hideya Suehiro et autres

BACKGROUND: Coronary spastic angina (CSA) sometimes complicates ventricular arrhythmias (VAs) leading to sudden death. The appropriate secondary prevention strategy remains to be discussed. Recently, the relationship between J waves and VAs in CSA has been reported. OBJECTIVES: We aimed to investigate the …

Identification of causative organisms using enrichment cultures for cardiac implantable electronic device infections

Mitsuru Takami, Goh Ohji, Kenichiro Onuma, Kimitake Imamura et autres

BACKGROUND: Approximately 7% to 29% of cardiac implantable electrical device (CIED) infection patients have unknown causative organisms using normal culture methods. An "enrichment culture" is an effective technique for identifying slow-growing, low-abundance, and fastidious microorganisms. OBJECTIVE: This study aimed to explore the …

Conduction characteristics in the left atrium of patients with perimitral atrial tachycardia post–pulmonary vein isolation

Mitsuru Takami, Ryudo Fujiwara, Atsushi Suzuki, Kunihiko Kiuchi et autres

Background: The electrical conduction properties of the left atrium (LA) in patients with perimitral atrial tachycardia (PMAT) after pulmonary vein isolation (PVI) are not completely understood. Objectives: The purpose of this study was to investigate the characteristics of the segmental conduction velocity …

Left atrial single-cell transcriptomics reveals amphiregulin as a surrogate marker for atrial fibrillation

Yuya Suzuki, Takuo Emoto, Shunsuke Sato, Takeshi Yoshida et autres

Atrial fibrillation (AF) is strongly associated with strokes, heart failure, and increased mortality. This study aims to identify the monocyte–macrophage heterogeneity and interactions of these cells with non-immune cells, and to identify functional biomarkers in patients with AF. Therefore, we assess the …
