Novel Workflow for Conversion of Catheter-Based ... - ScienceDirect
2021年1月1日 · A recent clinical trial has demonstrated that noninvasive radioablation (NIRA) has the potential to reduce recurrent ventricular tachycardia (VT) that is refractory to drugs and standard catheter ablation.
VT ablation based on CT imaging substrate visualization
2023年12月19日 · Subsequent analyses revealed that patients with ischemic cardiomyopathies appeared to derive a significant benefit from inHEART-assisted VT ablation procedures, with a higher rate of successful ablation (p = 0.05). Our findings indicate that inHEART-guided ablation is associated with reduced VT recurrence compared to conventional procedures.
Substrate mapping vs. tachycardia mapping using CARTO
2006年11月1日 · Aims For ablation of ventricular tachycardia (VT) in patients after myocardial infarction, a three-dimensional mapping system is often used. We report on our overall success rate of VT ablation using CARTO in 47 patients, with a subgroup analysis comparing VT mapping with the results of mapping that had to be performed during sinus rhythm or ...
Imaging to Facilitate Ventricular Tachycardia Ablation:
Catheter ablation is a well-established and effective strategy for the management of ventricular tachycardia (VT). However, the identification and characterization of arrhythmogenic substrates for targeted ablation remain challenging.
Ventricular tachycardia ablation guided or aided by scar ...
2022年4月14日 · The aim of the VOYAGE (Ventricular tachycardia ablatiOn and mYocardial scAr chracterization with maGnetic rEsonance) trial (ClinicalTrials.gov NCT04694079) is to test, in terms of efficacy, safety and efficiency, a tailored approach to VT ablation. The study will compare current standard of care with a tailored approach for VA radiofrequency ...
Ablation of Reentry-Vulnerable-Zones Determined by Left …
The primary mechanism of scar-related ventricular tachycardia (VT) is reentry caused by dispersion of activation and repolarization. 1–5 In hemodynamically stable tachycardias, an activation map can identify critical sites of the reentrant circuit that can then be targeted with ablation. 6 However, this is rarely accomplished as the majority ...
Substrate mapping with the CARTO 3 three-dimensional
To avoid acute obstruction of the left or right coronary artery, it is necessary to use coronary angiography or intracardiac ultrasound to monitor the position of the ablation catheter during...
(PDF) VT ablation based on CT imaging substrate ... - ResearchGate
2023年12月19日 · Background: Catheter ablation reduces ventricular tachycardia (VT) recurrence and implantable cardioverter defibrillator shocks in patients with VT and ischemic cardiomyopathy. The most...
Novel Workflow for Conversion of Catheter-Based ... - ScienceDirect
2021年1月1日 · Cardiac radioablation is a novel treatment option for therapy-refractory ventricular tachycardia (VT) ineligible for catheter ablation. Three-dimensional clinical target volume (CTV) definition is a key step, and this complex interdisciplinary procedure includes VT-substrate identification based on electroanatomical mapping (EAM) and its ...
Emergent Ablation for Ventricular Tachycardia: Predictors of …
Fifty consecutive patients hospitalized emergently for VT with structural heart disease who underwent catheter ablation were prospectively followed up for outcomes and complications. Of the 50 patients (mean age 67.6 ± 12.8 years), 86.0% were male, 62.0% had ischemic cardiomyopathy, and their median left ventricular ejection fraction was 28.5%.
