Abstract :
background: symptomatic recurrent mitral valve stenosis develops in some patients after percutaneous mitral valvuloplasty (pmv). this study assessed the immediate and early outcomes of redo pmv in patients with recurrent mitral valve stenosis after prior pmv.methods: fiftyfour patients (40 women and 14 men, mean age of 38±8.2 years) underwent a redo (second) pmv for symptomatic restenosis of mitral valve [with mitral valve area (mva) lt; 1.5 cm2]. redo pmv was performed at 5.8±1.2 years after the initial pmv.results: in this study, 48 hours after the procedure, there was a substantial increase in mva by 2dimensional echocardiography (ge, vivid 7) from 1.0±0.2 to 2.2±0.4 cm2 (p lt;0.001) and a decrease in mean left atrial pressure from 27 ± 5 to 15 ± 4 mmhg (p lt;0.001) and in mean transmitral valve gradient from 15±4 to 2±1 mmhg (p conclusion: redo pmv can be performed successfully in patients with recurrent mitral valve stenosis following previous percutaneous valvuloplasty.
