Redo percutaneous mitral valvuloplasty for mitral restenosis: a comparison with first procedure for de novo mitral stenosis.

Background: Percutaneous mitral valvuloplasty (PMV) has emerged as the procedure of choice in most patients with symptomatic mitral stenosis. However, very few reports have looked at redo PMV in patients with mitral restenosis.

Aim: In a retrospective study, we explored the immediate results of redo PMV compared to primary PMV.

Head-to-head comparison between redo percutaneous mitral valvuloplasty for mitral restenosis and percutaneous mitral valvuloplasty for de novo mitral stenosis.

Aims: In a retrospective study design, we explored the immediate results of redo-percutaneous mitral valvuloplasty in comparison with initial percutaneous mitral valvuloplasty.

Methods And Results: We included 30 consecutive patients with de-novo mitral stenosis (group A) and 40 consecutive patients with mitral restenosis after successful initial percutaneous mitral valvuloplasty (group B). Echocardiographic assessment of the mitral valve was performed in all patients by trans-thoracic echocardiography and transesophageal echocardiography excluded left atrial thrombosis.
