Autor: Satoshi Hara, Shigeki Kusa, Yoshikazu Sato, Hiroaki Ohya, Naoyuki Miwa, Hidenori Hirano, Taiki Ishizawa, Tadanori Nakata, Junichi Doi, Hitoshi Hachiya

Publikováno v: Journal of Arrhythmia, Vol 40, Iss 3, Pp 448-454 (2024)

Abstract Background The concept of ablation index (AI) was introduced to evaluate radiofrequency (RF) ablation lesions. It is calculated from power, contact force (CF), and RF duration. However, other factors may also affect the quality of ablation l

Determinants of Pericoronary Adipose Tissue Attenuation on Computed Tomography Angiography in Coronary Artery Disease

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 9, Iss 15 (2020)

Background Recent studies have reported the association between pericoronary inflammation assessed by pericoronary adipose tissue attenuation (PCATA) on computed tomography angiography and worse outcomes in patients with coronary artery disease. We i

Features Suggesting Preferential Conduction in Pulmonary Artery Ventricular Arrhythmia for Identification of Successful Ablation Sites

Autor: Hirotaka Muramoto, Yoshito Iesaka, Atsushi Suzuki, Yasuaki Tsumagari, Satoshi Hara, Hitoshi Hachiya, Yoshikazu Sato, Naoyuki Miwa, Yasuteru Yamauchi, Hiroaki Ohya, Kazuya Yamao, Osamu Inaba, Koji Higuchi, Tetsuo Sasano, Shigeki Kusa

Publikováno v: International heart journal. 62(4)

Radiofrequency catheter ablation (RFCA) for pulmonary artery ventricular arrhythmia (PAVA) can be difficult because of the occasional existence of PAVA with preferential conduction.This study described the characteristics of PAVA that demonstrate pre
