(A) Doppler graded (table) pulmonary regurgitation before (Pre) and one day after (Post) balloon dilatation of the pulmonary valve and at intermediate (ITFU) and late (LTFU) term follow up. There is a gradual but significant increase (p < 0.05 to p < 0.001) in the incidence of pulmonary regurgitation. (B) Nature of interventricular septal motion. There is a significant increase (p < 0.05) in the incidence of flat septal motion at LTFU. None of the patients had paradoxical septal motion.
