Approximate Thermal Modeling of Radiofrequency Cardiac Ablation
… efficacy and safety of radiofrequency catheter ablation (RFCA) of cardiac tissue. The purpose of RFCA is to carefully heat selected locations in the heart. The resulting thermal injury creates lesions which prevent the generation or propagation of arrhythmias. The ability to predict the …

Segmentation and visualization for cardiac ablation procedures
… to improve planning and outcome evaluation of cardiac ablation procedures. Cardiac ablation is a common medical procedure that consists of burning cardiac tissue causing atrial fibrillation, or irregular contractions of the heart's atria. We first propose a method for the automatic delineation …

A Study of Radiofrequency Cardiac Ablation Using Analytical and Numerical Techniques
<p>Studies on radiofrequency (RF) ablation are often aimed at accurately predicting tissue temperature distributions by numerical solution of the bioheat equation. This thesis describes the development of an analytical solution to serve as a benchmark for subsequent numerical solutions. The …

Bioelectrical strategies for image-guided therapies
… novel localization methods for the guidance of cardiac ablation and other minimally-invasive therapies. The first method, the Inverse Solution Guidance Algorithm (ISGA), is for the non-invasive and rapid localization of the site of origin of an arrhythmia and an ablation catheter tip from …

CyberCardia: Patient-specific electrophysiological heart model for assisting left atrium arrhythmia ablation
… to hundreds of thousands deaths annually. Cardiac ablation is among the most successful treatment options, involving the use of radio frequency energy to kill diseased cells or create lesion lines that obstruct abnormal activation waves. During the procedure, catheters are inserted into the …

Radiofrequency ablation versus cryoablation in the treatment of atrioventricular nodal reentrant tachycardia
… cases per year in the United States. Catheter ablation of AV node tissue has become the first-line definitive treatment for AVNRT, owing to its high efficacy, tolerability, and safety. Two modalities of ablation, radiofrequency (RF) and cryoablation are commonly utilized in clinical practice …

Improvements in Pulse Parameter Selection for Electroporation-Based Therapies
… electroporation (IRE) is a non-thermal tissue ablation modality in which electrical pulses are used to generate targeted disruption of cellular membranes. Clinically, IRE is administered by inserting one or more needles within or around a region of interest, then applying a series of short, …

Investigation of Single-Cell and Blood-Brain Barrier Mechanics after Electroporation and in Primary Brain Cancers
… or where cell viability is undesirable (tumor ablation, cardiac ablation). Precise control of cell shape and orientation enabled by nanofiber scaffolds provides a convenient and expedient platform for investigating a wide variety of factors (morphological and experimental) on cell viability. …
