Abstract
Methods and system for atrial fibrillation ablations utilizing cardiac mapping based on medical image(s). The methods and system also adapted for any balloon based catheters including cryoballoon catheter, laser balloon catheter, or “hot balloon” catheter, as well as circular catheters. The methods and system includes overlaying of two or more images on top of each other (where the images are of various types or modalities) and aligning the images, where the transparency between the images can be adjusted for navigating and optimal placement of the balloon based catheters or circular catheters. The images include 3-dimensional (3D) volume rendered computed tomography (CT) or Magnetic Resonance (MR) in segments, where the segments represents anatomical structures in separate digital files, which can be selectively turned ON or OFF. The method and system may also comprise the ability to monitor esophageal temperature, and act on pre-determined levels.
