Brief Summary
One of the goals of an ablation procedure is to create scarring of cardiac tissue. Not all ablations result in scar tissue. Advances in technology have improved scarring but ideal parameters that resu...
Detailed Description
A critical step to improve atrial fibrillation (AF) ablation broadly is to minimize interoperator variability. VISITAG SURPOINT calculated a marker tag index value by combining contact force, power se...
