The very best is Dr. Andre Natale in Austin, Tx. formerly of The Cleveland Clinic. He was instrumental in creating the PVI (pulmonary vein isolation) ablation. He's just the best!
I had a left side ablation done 4 years ago. My electrophysiologist was Lawrence Rosenthal of UMASS in Worcester, MA,. Excellent physician, all business. Prefers procedure done under general anesthesia. It was a very positive experience.
