ALVA, Carlos et al. Congenital Percutaneous Aortic Valvuloplasty in 70 Subjects with Congenital Aortic Stenosis: Mid-Term Results. Gac. Méd. Méx [online]. 2004, vol.140, n.3, pp.269-272. ISSN 2696-1288.

Objective: To evaluate mid-term results with Percutaneous aortic valvulopasty (PAV). Material and Methods: Records of 70 patients treated with percutaneous aortic valvuloplasty with at least 6 months follow-up were reviewed. Results: The 70 patients with PA Vaged 3 months to 36years, mean 10.5 ± 10.6 years, 40) 63%) were male and 26 (37%) female. Initial systolic peak gradient decreased from 84 ± 20 to 31 ± 16 mmHg (p < 0.05), while the reduction percentage ranged from 25 to 100%, mean 60 ± 22. Balloon/aortic annulus index was 0.9 ±0.17. Ten (14.1 %) patients developed aortic insufficiency after PA V. Follow-up ranged from 6 to 168 months, mean ± 48 months. At end of follow-up, 21 patients (30%) were considered failed cases and 49 (70%) patients had a successful outcome. Conclusions: This study showed a series with the longest follow-up in latin America with PA V. New prospective and multicentric studies are needed in this region.
