TRPV1-cardiac afferent ablation after completed myocardial infarction prevents arrhythmogenic remodeling

Kiyoshi Masuyama, Youmei Shen, Wei‐Hsin Chung, Abdullah Sarkar et autres

ABSTRACT Structured Abstract: Background Therapies to prevent ventricular arrhythmias after completed myocardial infarction (MI) remain limited. Although TRPV1 afferent ablation at acute MI improves cardiac remodeling, the effect of delayed subacute targeting remains unknown. Objective We investigated whether ablating cardiac TRPV1 afferents …

Residual Conduction across the Supero-Septal Ablation Line during Mitral-Isthmus Dependent Atrial Flutter

Takumi Yamada, Krittapoom Akrawinthawong, Yuichiro Miyazaki, Shumpei Mori

Mitral isthmus (MI)-dependent atrial flutter (AFL) often occurs after catheter ablation of atrial fibrillation.1 Linear ablation across the MI is the first line treatment for this AFL. However, achievement of conduction block at the MI is challenging because of residual epicardial connections. …

Successful ablation of Marshall Bundle–related perimitral atrial flutter using pulsed field ablation

Yae Min Park, Michael N. Jiang, Shumpei Mori, Justin H. Hayase

Perimitral atrial flutter (AFL) is one of the most challenging arrhythmias due to the complex anatomical characteristics of mitral isthmus and associated epicardial structures.1 Epicardial conduction through the Marshall bundle across the mitral isthmus remains a major barrier in achieving complete lesion …

Innervation of the Human Atrioventricular Node via the Inferior Pyramidal Space: Characterization Using Intersectional Strategies

Takanori Sato, Shumpei Mori, Peter Hanna, Joseph E. Hadaya et autres

BACKGROUND: The inferior pyramidal space (IPS), the epicardial adipose tissue extending from the inferior crux of the heart, contains the atrioventricular node (AVN) at its apex. However, innervation of the human AVN via the IPS remains unknown. METHODS: Seven whole-mount samples of …

Comparative performance of open thorax epicardial linear cryoprobe ablation versus focal tip radiofrequency catheter ablation in ventricular scar

Justin Hayase, Rami Aladham, Min Zhang, Gregory A. Fishbein et autres

BACKGROUND: Epicardial cryoablation is increasingly utilized in open surgical procedures for treatment of ventricular arrhythmias in patients with structural heart disease when percutaneous epicardial access cannot be obtained. There are limited data regarding the effects of cryoablation within ventricular scar tissue, particularly …

Aortic Valve Level as a Candidate Zone 4/5 Boundary Landmark in Endovascular Aortic Repair

Tatsuya Nishii, Hiroki Horinouchi, Akiyuki Kotoku, Shumpei Mori et autres

Abstract Background The zone 4/5 boundary has been described as the mid-descending aorta–T6 level, but this correspondence has uncertain anatomic support. Purpose To determine whether the aortic valve (AV) level approximates the descending aortic midpoint and to compare candidate boundaries relative to …

Transcatheter epicardial pacing of the human Bachmann’s bundle via the transverse sinus: Novel technique to expand transcatheter cardiac intervention

Yuichiro Miyazaki, Shumpei Mori, Mark Rimmer, Venkatakrishna N. Tholakanahalli

As atrial lead implantation in the right atrial appendage is technically straightforward, the right atrial appendage remains one of the common sites for atrial pacing. However, it induces interatrial conduction delay, resulting in interruption of the left atrial wave by the mitral …
