MethodWe retrospectively analyzed 92 consecutive MDCT studies done in 80 patients between January 2011 and June 2013; 70 (76%) studies were done before a first ablation procedure and 22 (24%) were done in patients who had undergone an ablation procedure. ResultsFindings were useful in 34% of the patients who underwent MDCT before the first ablation procedure and in 68% of the studies done after a procedure. The incidence of stroke associated with the ablation procedure was 3%, similar to the incidence recorded in our center before we started to use MDCT to evaluate the anatomy of the left atrium. All symptomatic patients had some pulmonary vein stenosis, and 80% had significant stenosis. Furthermore, the stenoses progressed very rapidly; treatment with balloon angioplasty was associated with early restenosis. Stenting was an alternative in cases of failed angioplasty. ConclusionIn the preprocedural evaluation and postprocedural follow-up of patients undergoing pulmonary vein isolation, MDCT is useful for guiding treatment and detecting complications. ER -
