Morishima Y, Chida K, Chiba H, Kumagai K
Ir J Med Sci . 2024 Oct; 193(6):2745-2751. PMID: 39367959
Background: Radio frequency catheter ablation (RFCA), a treatment for arrhythmia, requires a long fluoroscopy time that increases the radiation exposure dose to the physician, particularly to the lens of the...

J Arrhythm . 2024 Aug; 40(4):858-866. PMID: 39139889
Background: Blood pressure variability has been found to be a predictor of a stroke, heart failure, and ischemic heart disease that is independent of blood pressure control. This study used...

Pulm Circ . 2024 Apr; 14(2):e12377. PMID: 38681871
Chronic thromboembolic pulmonary hypertension (CTEPH) is a chronic disease that can rapidly deteriorate into circulatory collapse when complicated by comorbidities. We herein describe a case involving a 43-year-old woman with...

Minami K, Nakamura K, Maeno E, Iida K, Saito I, Masuyama T, et al.
J Clin Med . 2023 Mar; 12(5). PMID: 36902570
Background: Although pulmonary vein isolation (PVI) is an established procedure for atrial fibrillation (AF), non-PV foci play a crucial role in AF recurrence. Persistent left superior vena cava (PLSVC) has...

BMJ Open . 2023 Feb; 13(2):e068894. PMID: 36792334
Introduction: Data are lacking on the extent to which patients with non-valvular atrial fibrillation (AF) who are aged ≥80 years benefit from ablation treatment. The question pertains especially to patients'...

J Arrhythm . 2022 Feb; 38(1):86-96. PMID: 35222754
Background: This study aimed to evaluate the predictors of recurrence of atrial tachyarrhythmias by structural and functional mapping: voltage, dominant frequency (DF), and rotor mapping after a pulmonary vein isolation...
