31 Segmental ablates only areas that have potentials, not the whole pulmonary vein opening(s). It is even more difficult to make continuous linear ablation lines around the Pulmonary Vein openings because the inside of the heart is not a continuously smooth surface. The LEFT ATRIAL CATHETER ABLATION procedure is faster, easier, requires less operator’s skill, and is more cost effective for doctors. It will probably become the procedure of choice for most A-Fib medical centers. But from a patient’s perspective it involves a lot of scarring of the heart by high wattage catheters. And 20% of patients have atrial flutter after the procedure because of all the gaps in the lesion lines, though most of this flutter eventually disappears as these gaps fill in with scar tissue. (As of January, 2010, many use the term “Catheter Ablation” of A-Fib to include all of the above different ablation techniques.) 50.

Another question for patients is whether it’s better to ablate A-Fib generating areas in the heart, or leave them intact but block these areas from propagating A-Fib signals into the rest of the heart.
