Finite element analysis was used to estimate the ablation zone under a variety of voltage and pulse conditions. Cancer cells were cultured in vitro under two- and three-dimensional conditions to assess cell viability under different voltage and pulse conditions. Additionally, the expression of damage...
Abstract The term “Cardiac memory” (CM) refers to persistent changes in myocardial repolarization upon resumption of normal ventricular conduction sequence after a period of abnormal ventricular activation (such as ventricular arrhythmias, pacing, or transient conduction abnormalities) manifesting by the ...
Cardiac RT is an emerging treatment option for patients with refractory VT. The objective of this study was to define the structural, functional, and molecular effects of focused, single-fraction RT in the adult mammalian heart. Our findings suggest that radiation may be used therapeutically to mo...
To cure patients with symptomatic AF refractory or intolerant to antiarrhythmic drugs, PV isolation by intra-cardiac catheter ablation is recommended2. However, despite a high success rate, this intervention only benefits a small proportion of patients due to the sheer number of AF sufferers world...
LDTN stimulation could attenuate cardiac sympathetic remodeling and improve ventricular electrical remodeling, which may be mediated by suppressing the activated Wnt/β-catenin signaling pathway and then promoting the LSG neuronal apoptosis. Similar content being viewed by others Targeted ablation of the lef...

Acute success of radiofrequency cardiac ablation At the end of the procedures, all patients in both groups were free from inducible or spontaneous VT. The acute procedural endpoint was achieved in 100% cases. Induction of very fast VT (cycle length ≤200 ms) or VF, ventricular flutter, or ...
Cardiac mapping and ablation systems An electrode assembly for use in interventricular cardiac mapping includes one or more elongated splines each of which carries a plurality of spaced apart electrodes thereon. The body of each spline is formed of a plurality of alternatin... SD Edwards,TF Kordis...

Polymer electrodes: Crystallized films are suitable for cardiac interface Cardiomyocyte cells can be cultured and made to pulse on demand using transparent polymers with good stability. Conductive thin films formed from poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) have low impedance...
