No
This case report demonstrates that multiple monomorphic ventricular tachycardias can arise from a left ventricular false tendon and be successfully treated with catheter ablation under ICE guidance.
False tendon ablation may be considered for refractory multiple-morphology idiopathic VT; extends reported endocavitary substrates.
Catheter ablation has curative potential in patients with idiopathic ventricular tachycardia (VT). Different endocavitary structures, such as papillary muscles, moderator band, and false tendon, have been described as the substrate for idiopathic VT.1–4 Although single-morphology VT arising from a false tendon is a well-known entity, multiple monomorphic VTs requiring ablation of a false tendon have not been reported. We report the case of a patient with multiple monomorphic VTs induced in the electrophysiology (EP) laboratory, which were successfully ablated from the left ventricular false tendon under intracardiac echocardiographic (ICE) guidance.

Saggu et al. (2015) conducted a case report in Multiple monomorphic ventricular tachycardias (n=1). Catheter ablation of the left ventricular false tendon under ICE guidance was evaluated on Freedom from VT recurrence. Catheter ablation of the left ventricular false tendon under intracardiac echocardiographic guidance successfully eliminated multiple monomorphic ventricular tachycardias with no recurrence at 13 months.
