Core Tip
Core tip: We report a case of successful radiofrequency catheter ablation of premature ventricular complexes associated with left ventricular false tendons. Intracardiac echocardiography with the CartoSoundTM system was used to demonstrate, for the first time, that the occurrence of ventricular premature complexes was associated with false tendons. No classical Purkinje potential and special potential were observed following interventricular septum attachment of false tendons, the local potential of the target region in this patient, and the ectopic excitability resulting in mechanical traction at the false tendon attachment site of the interventricular septum may be a possible mechanism for these premature ventricular complexes.
