Percutaneous mitral valvotomy is a safe and effective treatment for symptomatic rheumatic mitral stenosis in children and adolescents, providing significant immediate hemodynamic improvement and sustained midterm symptom relief.
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.

Abdallah et al. (2015) conducted an observational in Mitral valve stenosis (n=64). Percutaneous mitral valvotomy was evaluated on Procedural success. Percutaneous mitral valvotomy achieved a 96.8% success rate in patients ≤ 18 years old, with low rates of immediate complications and restenosis during up to 24 months of follow-up.
