N/A Percutaneous mitral balloon valvuloplasty (PMV) using the double-balloon technique was performed in 28 symptomatic patients with mitral stenosis who were candidates for mitral valve commissurotomy. There were 21 women and 7 men with a mean age 38±10 years (range 23 to 57). PMV in 28 patients with moderate to severe mitral stenosis (including 3 with a fluoroscopic calcified valve) resulted in an increase mitral valve area (0.9±0.2 to 2.2±0,7cm, p<0.0001) by Gorlin`s formula, and a decrease in mean diastolic mitral pressure gradient (16.8±5.7 to 6.1±3.9mmHg, p<0.0001), and mean left atrial pressure (23.6±6.7 to 11.7±5.8mmHg, p<0. 0001). And also cardiac output increased (4.8±1.0 to 5. 8±1.5L/min, p<0.005) and mean pulmonary artery pressure decreased (32±12 to 24±9mmHg, p<0.05). Mitral regurgitation developed or increased in severity after PMV in 15 (53.6%) patients, grade 3mitral regurgitation in 2 and no mitral regurgitation in 12 patients. Oxymetric studies performed immediately after PMV demonstrated a small left-to-right shunt (pulmonary-to-systemic blood flow ratios>1.5) through the interatrial communication in 4 patients. Follow up echocardiography showed improvement in mitral valve area by 2-D and Doppler pressure half-time (0.9±0.2 to 1.8±0.5 and 0.8±0.2 to 1.7±0.4 cm, p<0.0001), increase of mitral EF slope (13±7 to 37±17mm/ sec, p<0.0001) and decrease peak E mitral velocity (209±32 to 142±32cm/sec, p<0.0001). Transient cerebral embolic phenomenon just after PMV was observed in 1 patient and cerebral embolic infarction with hemorrhage requiring surgery developed in 1 patient. PMV using the double-balloon technique is safe and effective procedure to relieve mitral valve obstruction and could be an alternative to surgical mitral commissurotomy in selected patients with mitral stenosis.
