Abstract

|
Three-dimensional (3D) mapping systems are useful tools for the diagnosis and treatment of atypical arrhythmias following open heart surgery. In this case, a patient experienced incessant tachycardia after aortic valve surgery. Two-dimensional fluoroscopy-guided catheter ablation and intensive antiarrhythmic pharmacological treatment, in addition to a permanent pacemaker, failed to control the tachycardia. A 3D mapping system revealed that the mechanism of the tachycardia involved macroreentry around the right atriotomy scar, and the tachycardia circuit was blocked by 3D-guided catheter ablation.
