Right ventricular outflow tract (RVOT) obstruction is among the commonest congenital heart defects in the grown-up, and pulmonary stenosis is the dominant subtype. We described our successful novel surgical technique of totally robotic antegrade RVOT repair in two cases of pulmonary stenosis with concomitant repair of atrial septal defect using da Vinci SI Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA USA) with excellent surgical outcome. We conclude that robotic antegrade repair of the valvular and subvalvular subset of RVOT obstruction is feasible in adults.
