Comparison of two different techniques for balloon sizing in percutaneous mitral balloon valvuloplasty: which is preferable?

摘要

Background: Percutaneous balloon mitral valvuloplasty (BMV) is an important option for the treatment of mitral valve stenosis. The crux of this process is choosing the appropriate Inoue balloon size. There are two methods to do this. One is an empirical formula based on the patient's height, and other is to choose according to the maximal inter-commissural distance of the mitral valve provided by echocardiography.
