Clinical Impact of Interlesion Distance on Acute Pulmonary Vein Isolation Success in Patients With Paroxysmal Atrial Fibrillation

Keika Oyama, Yoshihisa Naruse, Yuki Arakawa, Shuhei Kobayashi et autres

Background: Achieving pulmonary vein isolation (PVI) through contiguous lesions is important for durable PVI treatment of atrial fibrillation (AF). We hypothesized that the flexible-tip TactiFlex catheter, with its enhanced stability, would allow for successful acute PVI even with an extended interlesion distance …

Comparison of Spatio‐Temporal Dispersion Electrogram Ablation and Low Voltage Zone Ablation in Patients With Persistent Atrial Fibrillation

Yutaro Kaneko, Yoshihisa Naruse, Yuki Tokonami, Kazuki Ito et autres

BACKGROUND: Pulmonary vein isolation (PVI) alone was less effective for patients with persistent atrial fibrillation (AF) compared to those with paroxysmal AF. Although the TAILORED AF trial demonstrated the efficacy of spatio-temporal dispersion electrogram (STDE) ablation as additional treatment for PVI, comparisons …

Improvement in the severity of sleep disordered breathing three months after pulmonary vein isolation in patients with persistent atrial fibrillation

Y Naruse, Taro Narumi, Y Tokonami, K Ito et autres

Abstract Introduction Sleep-disordered breathing (SDB) is common in patients with atrial fibrillation (AF), and its treatment reduces AF recurrence after pulmonary vein isolation (PVI). However, research examining the impact of sinus rhythm restoration through PVI on SDB is limited. We previously reported …

Comparison of the area of spatiotemporal dispersion electrograms obtained before and after pulmonary vein isolation in patients with persistent atrial fibrillation

Y Naruse, T Tamura, Y Takazawa, Y Tokonami et autres

Abstract Background Recently, the TAILORED AF trial reported that catheter ablation targeting spatiotemporal dispersion electrograms (STDEs), in addition to pulmonary vein isolation (PVI), was associated with a decreased risk of atrial fibrillation (AF) recurrence after the ablation compared to the conventional approach …

Efficacy and Safety of Catheter Ablation in Very Elderly Patients With Atrial Fibrillation: Short‐ To Mid‐Term Outcomes From a Multicenter Study

Takumi Tamura, Yoshihisa Naruse, Taro Narumi, Yuki Tokonami et autres

ABSTRACT Background Catheter ablation has become a cornerstone of atrial fibrillation (AF) treatment. The prevalence of AF increases with age. However, research on catheter ablation in very elderly patients (age ≥ 80 years) is limited. This study aimed to assess the efficacy …

Association between sinus rhythm restoration and sleep-disordered breathing at three months after pulmonary vein isolation for persistent atrial fibrillation

Taro Narumi, Yoshihisa Naruse, Yuki Tokonami, Kazuki Ito et autres

BACKGROUND: Sleep-Disordered Breathing (SDB) is common in patients with Atrial Fibrillation (AF), and its treatment reduces AF recurrence after Pulmonary Vein Isolation (PVI). However, the mid-term impact of sinus rhythm restoration on SDB remains unclear. METHODS AND RESULTS: The authors retrospectively analyzed …

Technical Tips and Efficacy of Leadless Pacemaker Implantation in a Patient With Isolated Persistent Left Superior Vena Cava

Yuki Tokonami, Makoto Sano, Taro Narumi, Yoshihisa Naruse et autres

Isolated persistent left superior vena cava (PLSVC) provides limited access during transvenous pacemaker implantation. We present a case of implantation of a leadless pacemaker for atrioventricular block with isolated PLSVC. A leadless pacemaker is an alternative strategy to a transvenous pacemaker; however, …

Clinical feasibility of high‐power short‐duration strategy at the sites adjacent to the esophagus during laser balloon‐based pulmonary vein isolation

Haruta Kato, Yoshihisa Naruse, Yutaro Kaneko, Taro Narumi et autres

Abstract Background Laser balloon‐based pulmonary vein isolation is an established therapeutic option for atrial fibrillation. However, elevated esophageal temperature is sometimes problematic and increases the risk of collateral esophageal damage. This study aimed to evaluate the efficacy and safety of different power …

Successful implantation of a cardiac resynchronization therapy device assisted with Impella in a patient with severe decompensated heart failure

Kyoko Unno, Makoto Sano, Yutaro Kaneko, Tomoaki Sakakibara et autres

Cardiac resynchronization therapy (CRT) is a cornerstone of heart failure with reduced left ventricular (LV) ejection fraction and a wide QRS duration. Implantation of a CRT device is usually scheduled in the compensated phase of heart failure. We report a case of …
