Dukkipati S, Nakamura T, Nakajima I, Oates C, Narui R, Tanigawa S, et al.
Circ Arrhythm Electrophysiol
. 2022 Apr;
15(5):e010020.
PMID: 35476455
Background: Frequent premature ventricular contractions (PVCs) are often amenable to catheter ablation. However, a deep intramural focus may lead to failure due to inability of standard ablation techniques to penetrate...

Arch Med Sci
. 2020 Sep;
16(5):1022-1030.
PMID: 32863990
Introduction: Respiratory sinus arrhythmia (RSA) describes heart rate (HR) changes in synchrony with respiration. It is relevant for exercise capacity and mechanistically linked with the cardiac autonomic nervous system. After...

J Cardiovasc Electrophysiol
. 2020 Aug;
31(10):2645-2652.
PMID: 32748442
Introduction: Tailored catheter ablation of atrial tachycardias (ATs) is increasingly recommended as a potentially easy treatment strategy in the era of high-density mapping (HDM). As follow-up data are sparse, we...

JACC Clin Electrophysiol
. 2020 Jul;
6(7):760-769.
PMID: 32703556
Objectives: This study sought to identify midmyocardial arrhythmogenic substrates by examining the frequency content of unipolar endocardial surface electrograms, comparing sites with transmural scar versus sites with intramural excitable substrate...

J Cardiovasc Electrophysiol
. 2020 Feb;
31(5):1051-1061.
PMID: 32107811
Introduction: The aim of this study was to investigate electrophysiological findings in patients with arrhythmia recurrence undergoing a repeat ablation procedure using ultra-high-density (UHDx) mapping following an index procedure using...

Heart Rhythm
. 2019 Oct;
17(3):398-405.
PMID: 31604127
Background: Intramural substrate causing ventricular tachycardia can be targeted by radiofrequency (RF) infusion-needle catheter ablation. Objective: The purpose of the study was to assess fluid distribution within the myocardium after...

JACC Clin Electrophysiol
. 2019 Apr;
5(4):417-426.
PMID: 31000095
Objectives: This study sought to characterize primary left atrial tachycardia (LAT) mechanisms, electrical properties and substrate using high-density mapping. Background: Nonfocal LAT can be found in patients without prior substrate...

J Am Coll Cardiol
. 2019 Mar;
73(12):1413-1425.
PMID: 30922472
Background: Catheter ablation is effective for eliminating most drug-refractory ventricular arrhythmias (VA). However, a major reason for procedural failure is arrhythmia originating deep within the myocardium where it is inaccessible...

Heart Rhythm
. 2019 Feb;
16(7):1021-1027.
PMID: 30710740
Background: Catheter ablation for polymorphic ventricular tachycardia and ventricular fibrillation (PMVT/VF) may target triggering premature ventricular contractions (PVCs). Targeting ventricular scar has also been suggested, but data are limited. Objective:...

Circ Arrhythm Electrophysiol
. 2018 Nov;
11(11):e006714.
PMID: 30376734
Background: Percutaneous pericardial access for catheter ablation is associated with a bleeding risk. We sought to elucidate the relation of hemorrhagic and thromboembolic events associated with epicardial procedures to anticoagulation...
