Successful Pulsed Field Ablation for Paroxysmal Atrial Fibrillation in a Patient with Type 1 von Willebrand Disease under Perioperative Recombinant Human von Willebrand Factor Supplementation

Motoki Endo, Atsuhiko Yagishita, Kazuma Iimura, Aika Iijima et autres

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and a major risk factor for stroke and heart failure. 1 Catheter ablation with pulmonary vein isolation (PVI) is an established rhythm-control strategy for drug-refractory paroxysmal AF. 2 Pulsed field ablation (PFA), …

Prospective Clinical Outcomes of Cardiac Stereotactic Body Radiotherapy for Refractory Ventricular Tachycardia ― Insights From Dose Distribution in Survivors ―

S. Kabuki, Mari Amino, Etsuo Kunieda, Toshihisa Kuroki et autres

BACKGROUND: Clinical outcome determinants in cardiac stereotactic body radiotherapy (cardiac-SBRT)/stereotactic arrhythmia radioablation (STAR), a minimally invasive therapy for refractory ventricular tachycardia (VT), remain unclear. We report the final analysis of Japan's first prospective study following a previously published interim report. METHODS AND …

Delayed-Onset Life-Threatening Takotsubo Cardiomyopathy Following Pulsed-Field Ablation

Kazuma Iimura, Atsuhiko Yagishita, Aika Iijima, Mari Amino et autres

BACKGROUND: Pulsed-field ablation (PFA) is a novel nonthermal modality for atrial fibrillation ablation. Takotsubo cardiomyopathy (TTC) is associated with autonomic dysregulation, but its relationship with PFA remains unclear. CASE SUMMARY: A 62-year-old man underwent redo PFA including pulmonary vein, posterior wall, and …

Open‐Window Mapping for Accessory Pathway Ablation: Influence of Catheter Design on Mapping Performance

Kazuma Iimura, Atsuhiko Yagishita, Aika Iijima, Mari Amino et autres

ABSTRACT Background Open‐window mapping (OWM) using the extended early‐meets‐late (EEML) algorithm is widely used for accessory pathway (AP) localization. However, the impact of catheter design on mapping performance and procedural outcomes remains unclear. Methods We retrospectively analyzed 43 consecutive patients undergoing OWM‐guided …

Ventricular fibrillation immediately after pulsed field energy delivery in persistent atrial fibrillation

Kazuma Iimura, Atsuhiko Yagishita, Aika Iijima, Mari Amino et autres

Pulsed field ablation (PFA) has rapidly gained adoption as a novel energy modality for catheter ablation of atrial fibrillation (AF), owing to its myocardial selectivity and favorable safety profile compared with conventional thermal ablation techniques (1). By inducing irreversible electroporation, PFA enables …

Assessment of incomplete lesions using 3-dimensional mapping following pentaspline pulsed field ablation for atrial fibrillation

Atsuhiko Yagishita, Kazuma Iimura, Aika Iijima, Mari Amino et autres

Background Pulsed field ablation (PFA) is a novel non-thermal modality for pulmonary vein isolation (PVI) in atrial fibrillation (AF). However, the completeness of lesion formation following PFA using a penta-spline catheter remains insufficiently studied. Objective To evaluate the utility of three-dimensional (3D) …

Reversal of complete left bundle branch block preceding functional recovery in nonischemic dilated cardiomyopathy treated with contemporary guideline-directed medical therapy

Atsuhiko Yagishita, Kazuma Iimura, Aika Iijima, Mari Amino et autres

Complete left bundle branch block (CLBBB) in patients with non-ischemic dilated cardiomyopathy (DCM) is associated with ventricular dyssynchrony, impaired systolic function, and poor prognosis. Current guidelines recommend cardiac resynchronization therapy (CRT) for symptomatic patients with left ventricular ejection fraction (LVEF) ≤35% and …
