Methods and system for atrial fibrillation ablations utilizing cardiac mapping based on medical image(s). The method 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) and aligning the images, where the transparency between the images can be adjusted as an aid for optimal placement of the balloon based catheters or circular catheters. 3D volumetricTags and markers are also placed on 3D images such as CT and MRI images which are indicative of where the tissue has been ablated. The method and system also comprises the ability to monitor esophageal temperature, and to activate alarms and/or energy delivery interrupt based on pre-determined esophageal temperature parameters.
