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 @entity1 with de-novo @entity4794 (group A) and 40 consecutive @entity1 with @entity339 after successful initial percutaneous mitral valvuloplasty (group B). Echocardiographic assessment of the mitral valve was performed in all @entity1 by trans-thoracic echocardiography and transesophageal echocardiography excluded @entity715 . Percutaneous mitral valvuloplasty was performed by the antegrade trans-septal approach using either the standard Inoue technique or the multi-track technique. @entity1 assessment by trans-thoracic echocardiography was repeated 48 hours following the procedure. Procedural success was defined as a 50% or more increase of mitral valve area with a final mitral valve area > or = 1.5 cm2, without major complications. Procedural success was achieved in 28 (93.3%) @entity1 in group A and in 37 (92.5%) @entity1 in group B (p > 0.05). The two groups were similar concerning the final mitral valve area, gain of mitral valve area, mean pressure gradient across the mitral valve and complication rate (p > 0.05 for all). The final mitral valve area correlated negatively with the initial mitral valve score in both group A and B. CONCLUSION: Redo-percutaneous mitral valvuloplasty for @entity339 achieves comparable immediate results to initial percutaneous mitral valvuloplasty.
