Systematic Characterization of High-Power Short-Duration Ablation: Insight From an Advanced Virtual Model
High-power short-duration (HPSD) recently emerged as a new approach to radiofrequency (RF) catheter ablation. However, basic and clinical data supporting its effectiveness and safety is still scarce
Tissue drives lesion: computational evidence of interspecies variability in cardiac radiofrequency ablation
Radiofrequency catheter ablation (RFCA) is widely used for the treatment of various types of cardiac arrhythmias. Typically, the efficacy and the safety of the ablation protocols used in the clinics are derived from tests ...
How does radiofrequency ablation efficacy depend on the stiffness of the cardiac tissue? Insights from a computational model
Objective. Radiofrequency catheter ablation (RFCA) is an effective treatment for the elimination of cardiac arrhythmias, however it is not exempt from complications that can risk the patients’ life. The efficacy of the ...
A least-squares implicit RBF-FD closest point method and applications to PDEs on moving surfaces
The closest point method (Ruuth and Merriman, J. Comput. Phys. 227(3):1943-1961, ) is an embedding method developed to solve a variety of partial differential equations (PDEs) on smooth surfaces, using a closest point ...
Effect of Tissue Elasticity in Cardiac Radiofrequency Catheter Ablation Models
Radiofrequency catheter ablation (RFCA) is an effective treatment for different types of cardiac arrhythmias. However, major complications can occur, including thrombus formation and steam pops. We present a full 3D ...
A computational model of open-irrigated radiofrequency catheter ablation accounting for mechanical properties of the cardiac tissue
Radiofrequency catheter ablation (RFCA) is an effective treatment for cardiac arrhythmias. Although generally safe, it is not completely exempt from the risk of complications. The great flexibility of computational models ...
An RBF-FD closest point method for solving PDEs on surfaces
Partial differential equations (PDEs) on surfaces appear in many applications throughout the natural and applied sciences. The classical closest point method (Ruuth and Merriman, J. Comput. Phys. 227(3):1943-1961, ...
