Figure 1: Main pulmonary artery opened longitudinally up to the annulus and incision extended across the annulus. The length of the monocusp measured as distance from the apex of the RVOT incision to the pulmonary annulus level and the width at the free edge was equal to the circumference of the native annulus. TV = Tricuspid valve; RV = Right ventricle; PA = Pulmonary artery
