Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]
, 2002 Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Catheter ablation and arrhythmia.
Nihon Naika Gakkai Zasshi, 1993 直流通電カテーテルアブレーションは,焼灼力は強いが,衝撃波発生等による重篤な合併症があり,普及しなかった.最近安全性の高い高周波通電法が開発され,薬物抵抗性の頻脈性不整脈に対し,広く臨床応用されるようになった.難治性の頻脈性心房細動,組動では主にHis束を焼灼して房室ブロックを作成し,ぺースメーカーを植え込む.房室結節回期頻拍に対しては,二重経路のうちのslow pathwayを選択的に焼灼し,房室ブロックの合併なく頻脈を完治させる. WPW症候群では,房室副伝導路を選択的に焼灼し,完全離断しうる.右室流出路起源等の特発性心室頻拍においても,その発生源を焼灼して完治させる.高周波通電法は安全性が高く,合併症はまれである.しかし深達度が浅いため,心筋梗塞や心筋症に伴う心室頻拍に対する有効性が低く ...

Role of Catheter Ablation in Arrhythmogenic Right Ventricular Dysplasia [PDF]
, 2005 Arrhythmogenic right ventricular dysplasia/cardiomyopathy is a disorder characterized by frequent ventricular tachycardia originating from the right ventricle and fibro-fatty replacement of right ventricular myocardium. Though the disorder was originally

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]
, 2019 BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Short and Intermediate Term Outcomes of the Convergent Procedure: Initial Experience in a Tertiary Referral Center [PDF]
, 2020 PURPOSE: The Convergent procedure is a hybrid, multidisciplinary treatment for symptomatic atrial fibrillation (AF) consisting of minimally invasive surgical epicardial ablation and percutaneous/catheter endocardial ablation.

Molecular Oncology, EarlyView.Combining melting curve analysis enhances the multiplexing capability of digital PCR. Here, we developed a 14‐plex assay to simultaneously measure single nucleotide mutations and amplifications of KRAS and GNAS, which are common driver genes in pancreatic cancer precursors. This assay accurately quantified variant allele frequencies in clinical samples
