Usefulness of electroanatomical mapping during transseptal endocardial left ventricular lead implantation [PDF]

, 2015
AimFailure rate to implant left ventricular (LV) lead transvenously is 4-8% in cardiac resynchronization therapy (CRT) patients. Epicardial lead placement is an alternative method and if not applicable case reports and small series showed the ...

Electrophysiological Features of Atrial Flutter in Cardiac Sarcoidosis: A Report of Two Cases

Indian Pacing and Electrophysiology Journal, 2012
We report two cases of systemic sarcoidosis with atrial flutter as the clinical manifestation. In one patient, who had symptoms of shorter duration, the arrhythmia was no longer inducible after a course of glucocorticoid therapy.

Effect of Epicardial Fat on Electroanatomical Mapping and Epicardial Catheter Ablation [PDF]

, 2009
ObjectivesThe purpose of this study was to correlate 3-dimensional distribution of epicardial fat on computed tomography (CT) with electroanatomical (EA) voltage maps obtained during percutaneous epicardial mapping in order to determine the fat thickness

Direct Comparison of Adjacent Endocardial and Epicardial Electrograms: Implications for Substrate Mapping [PDF]

, 2014
Background: Analysis of unipolar voltage maps has been used to detect epicardial scar, but data to define optimal parameters to identify scar remote from the recording site is limited.

Catheter-based intramyocardial delivery (NavX) of adenovirus achieves safe and accurate gene transfer in pigs. [PDF]

PLoS ONE, 2013
BACKGROUND: Hepatocyte growth factor (HGF) is one of the major angiogenic factors being studied for the treatment of ischemic heart diseases. Our previous study demonstrated adenovirus-HGF was effective in myocardial ischemia models.

Efficacy of Electroanatomical Mapping for Radiofrequency Ablation of Right-sided Accessory Pathways

Journal of Arrhythmia, 2005
Introduction: Due to the difficulty in performing detailed mapping around the tricuspid annulus and the high occurrence of mechanical trauma during the procedure, the outcome of right-sided accessory pathway (AP) ablation still has a relatively high ...

3-Dimensional Electroanatomic Mapping During MitraClip Procedure

JACC: Cardiovascular Interventions, 2020
Transesophageal echocardiography (TEE) is mandatory to achieve percutaneous mitral valve repair using the MitraClip system (Abbott Vascular, Santa Clara, California). However, a clear image cannot always be obtained via TEE in certain patients, particularly those with cardiac anomalies ...
