AbstractIntroductionPercutaneous balloon valvuloplasty is the primary treatment for critical pulmonary valve stenosis in neonates. Thus far, a few studies have reported long-term results of this technique in neonatal critical pulmonary valve stenosis.MethodsWe carried out a retrospective study of all consecutive newborns with critical pulmonary valve stenosis subjected to percutaneous balloon valvuloplasty at a single centre, between 1994 and 2014, to assess its immediate and long-term safety and efficacy.ResultsA total of 24 neonates presented with critical pulmonary valve stenosis. The mean diameter of the pulmonary annulus was 7 mm (±1.19); 33.3% had a dysplastic pulmonary valve, and 92% were started on prostaglandin E1 treatment. Percutaneous balloon valvuloplasty was performed at a mean age of 4.0±4.3 days using, on average, a balloon-to-pulmonary annulus ratio of 1.18 mm (with a range from 0.9 to 1.43). Immediate success was achieved in 22/24 patients (92%) with a reduction in the pulmonary transvalvular peak gradient (p<0.05) and in the right ventricle/systemic pressure ratio (p<0.05). There was one death (4%) 6 days after the procedure, and 29.2% of them had transient rhythm complications. For a mean follow-up time of 8.4 years, the re-intervention rate was 42.9%. In total, 14 re-interventions were performed in nine neonates, including surgery in six. Freedom from re-intervention was 50% at 8 years and 43% at 10 and 15 years.ConclusionThis series, to the best of our knowledge, has had the longest follow-up of neonates with critical pulmonary valve stenosis. Percutaneous balloon valvuloplasty is a safe and effective treatment, and in our study 75% of the patients were exclusively treated using this technique.
