Unusual presentation of RVOT aneurysm

Right ventricular outflow tract tachycardia is a type of monomorphic VT which originates from the outflow tract of the right ventricle or occasionally from the tricuspid annulus. It usually occurs in structurally normal heart but can also occur in patients with structural heart disease. A 45 year old male was referred to our hospital for EP study and RF ablation. Patient had multiple episodes of palpitations in the past 1 month and these were diagnosed as episode of ventricular tachycardia which were reverted each time with Direct Current Cardioversion in another hospital. Patient was diagnosed as case of RVOT VT, Double Chamber Right Ventricle, outlet VSD (restrictive) with RVOT aneurysm. He was managed conservatively and advised surgical repair.
