Objective: To analyze immediate and midterm results of percutaneous mitral valvotomy (PMV) in patients ≤ 18 year, a single centre experience of Sohag university hospital. Methods: Between May 2010 and May 2012, 64 procedures of Inoue technique mitral valvotomy were performed on 64 patients. The mean age was 15.8 ± 2.2 years;75% were females. Results: Success was obtained in 96.8% of patients. Immediate complications were severe mitral regurgitation (3.1%), cardiac tamponade (1.6%) and embolic stroke in (1.6%). Late follow-up was obtained in 93.7% of the patients (at 6 and 24 months). Restenosis developed in 3 patients. Most of the patients had no symptoms at discharge but most of them had NYHA class I to II at 6 months to 2 years follow up. No patients died. Patients who operated early with MVA around 1.4 had best outcome. Conclusion: PMV represents a safe therapeutic option in young patients with mitral valve stenosis. In these patients, recurrence of symptoms and restenosis occurs at an earlier stage than in elderly. Earlier intervention carries better outcome and decreases restenosis rate.
