Background: To assess immediate and intermediate outcomes of percutaneous balloon pulmonary valvuloplasty (BPV) in children and adults. Materials and Methods: This retrospective, single-center study included patients who had undergone balloon valvuloplasty for the treatment of moderate to severe pulmonary stenosis at a tertiary care center in India between May 2011 and July 2018. Clinical profile, echocardiographic details, procedural details, complications, short term, and intermediate results were assessed. Results: A total of 43 patients were assessed. The mean age of the study population was 13.87 ± 11.71 years. Of them, 21 (48.8%) patients were men and 30 (69.8%) patients were children/adolescents. Single-balloon technique was used in all the cases. Balloon/annulus ratio was 1.28 ± 0.04. Immediate procedural success (Group 1) and partial procedural success (Group 2) were achieved in 26 (60.5%) and 17 (39.5%) patients, respectively. The right ventricular systolic pressure reduced from 117.70 ± 31.77 mmHg to 53.56 ± 13.29 mmHg postprocedure (P < 0.001). Peak-to-peak transvalvular gradient reduced from 102.81 ± 31.66 mmHg to 35.56 ± 12.47 mmHg postprocedure (P < 0.001). Intermediate follow-up was conducted for 2.61 ± 0.75 years (range: 2–4 years). At intermediate follow-up, peak-to-peak instantaneous gradient was 27.21 ± 5.80 mmHg. Restenosis, moderate, and severe pulmonary regurgitation were reported in 2 (7.1%), 4 (14.3%), and 2 (7.1%) patients, respectively. Conclusion: Percutaneous BPV is a safe and efficacious procedure for the treatment of moderate to severe pulmonary valve stenosis in children and adults. The procedure had excellent immediate and intermediate follow-up results.
