Noninvasive electrocardiographic imaging for cardiac electrophysiology and arrhythmia. , Tokuda M, Sobieszczyk P, Eisenhauer AC, et al. One of the major challenges is the definition of the endpoint following ablation. Three different balloon-based technologies have been used to ablate PV ostia; cryoablation, high intensity ultrasound and laser.2 These ablation systems are designed to either ablate the entire ostium of the pulmonary vein or certain arcs of the pulmonary vein circumference.2 Initially there were reports of limited success with balloon-based techniques due to their inability to ablate non-PV sites and technical challenges associated with isolation of the right inferior pulmonary vein. Long flexible tubes (catheters) are threaded through blood vessels to the heart. Which Arrhythmias Can Be Treated With Ablation? Where views/opinions are expressed, they are those of the author(s) and not of Radcliffe Medical Media.
