Abstract:
Two cases with severe pectus excavatum and symptomatic atrial fibrillation (AF) underwent radiofrequency catheter ablation (RFCA). Their chest X-ray and computed tomography (CT) findings revealed lateral displacement and clockwise rotation of their hearts, and severe right atrial and mild right ventricular compression against the sternum, but no left atrium compression against the spinal column. The procedure was therefore carefully performed under guidance with CT, intra-cardiac echography, atriography, and a three-dimensions mapping system. Finally, the AF was successfully treated by RFCA without any complications. These findings underscore the importance of understanding cases of abnormal anatomy and carefully designing a strategy before performing any procedure.
