ABSTRACT:
A method for treatment of atrial fibrillation includes utilizing mathematical analysis, e.g., logistic regression, on a collection of variables selected from the group including effective refractory period, wavelength, tissue area, tissue weight, maximum tissue width, minimum tissue width, and average tissue width to design a set of lesions that would make an atria fibrillation-proof. Preferably, the most preferred variables are tissue area, effective refractory period, and conduction velocity. This is preferably an electrophysiologically-customized procedure that is preferably minimally invasive, which could include transvenous or port access, either off or on bypass to create the set of lesions that render an atria fibrillation-proof based on the mathematical analysis of selected variables. Long linear lesions are created from a variety of energy sources as well as surgical techniques. Preferably, there are fixation and marking mechanisms utilized.
