Effect of Fat Deposition on the Performance in RF Ablation
IntroductionThe outcomes of catheter ablation of scar-mediated ventricular tachycardia (VT) remain far from perfect. The presence of fat as a component of the ...
[EN] Background and objectives: To study temperature distribution and lesion size during two repeated radiofrequency (RF) pulses applied at the same point in the context of RF cardiac ablation (RFCA). Methods: An in-silico ...

[EN] Introduction: The use of ultra-short RF pulses could achieve greater lesion depth immediately after the application of the pulse due to thermal latency.
Methods and results: A computer model of irrigated-catheter RF ...
