JUAREZ RODRIGUEZ, Mariano et al. Balloon pulmonary valvuloplasty: 15-years experience at the Centro Médico Nacional "Siglo XXI", IMSS. Arch. Cardiol. Méx. [online]. 2003, vol.73, n.3, pp.190-196. ISSN 1665-1731.

Objective: To evaluate 15 years of experience with balloon pulmonary valvuloplasty in a single third level health care center. Material and methods: Hundred-fifty patients underwent the procedure, 73 (48%) men and 77 (52%) women, mean age 10.5 ± 11.3 years. Results: The initial systolic gradient decreased from 86 ± 35 to 21.67 ± 12.20 mm Hg, p < 0.001, whereas the initial right ventricular systolic pressure decreased from 106 ± 34-8 to 53 ± 27 mm Hg, p < 0.0001. At the end of the follow-up, 48 ± 44 months, the systolic gradient was 13.43 ± 8.73 mm Hg, p < 0.001. Major complications occurred in 9 (6.4%) patients. Immediate technical success was achieved in 111 (74%) patients and failure in 39 (26%). At the end of the follow-up period, successful outcomes were achieved in 104 (89.6%); in contrast, failures were present in 12 (10.4%) patients, p < 0.001. Death occurred in 2 (1.33%) patients. The predictors for failure were age < 1.5 ± 1-33 years (p < 0.004), dysplastic valve (p < 0.001), high initial systolic gradient (p < 0.002), and high initial systolic right ventricular pressure (p < 0.0001). Conclusion: Balloon pulmonary valvuloplasty is an effective, safe, and first choice treatment for congenital pulmonary valve stenosis. (Arch Cardiol Mex 2003; 73:190-196).
