Three-Dimensional Echocardiographic Assessment Before and After Percutaneous Transvenous Mitral Commissurotomy in Patients with Rheumatic Mitral Stenosis

摘要

Background and aim of the study: Real-time three-dimensional transthoracic echocardiography (RT3DE) is a relatively recent imaging technique that provides excellent image quality of the mitral valve. It has been suggested that this new echocardiographic modality, which allows a precise cross-section of the mitral orifice at the tips of the leaflets with correct plane orientation, may provide a more accurate assessment of rheumatic mitral stenosis (MS) than two-dimensional echocardiography (2DE), before and after percutaneous transvenous mitral commissurotomy (PTMC).Methods: A total of 50 patients with symptomatic mitral stenosis who underwent PTMC was evaluated prospectively. Patients in all age groups, with evidence of severe MS admitted to the authors' institution, in whom PTMC was feasible were included.Results: A good valve opening was observed in 45 patients (90%).
