Background Although accurate modeling of the thermal performance of irrigated-tip
electrodes in radiofrequency cardiac ablation requires the solution of a triple coupled …

Objective. Thermal cellular injury follows complex dynamics and subcellular processes can
heal the inflicted damage if insufficient heat is administered during the procedure. This work …

Abstract Since 1985, radiofrequency (RF) technology has grown to become the predominant
energy source for performing cardiac ablations of various atrial and ventricular arrhythmias …

Radiofrequency ablation is a minimally invasive treatment for cardiac arrhythmias. During
the procedure, the catheter is placed at the arrhythmogenic site to deliver electric current …

Background HeartLander is a tethered robot walker that utilizes suction to adhere to the
beating heart. HeartLander can be used for minimally invasive administration of cardiac …

Pulmonary vein isolation (PVI) is a cornerstone in catheter ablation of atrial fibrillation (AF).
Creation of transmural and contiguous radiofrequency (RF) lesions is necessary to achieve …

Radiofrequency ablation is a typical treatment for severe cases of cardiac arrhythmias. A
catheter, inserted from the patient's groin, delivers current at frequencies of 450–500 kHz to …
