Abstract:
Percutaneous mitral commissurotomy (PMC) remains essential in treating mitral stenosis (MS). Thanks to technological advancements and interventional cardiologists' progress, this procedure thrives with optimized equipment. However, patient selection remains a crucial factor in achieving successful outcomes. In practice, challenging situations arise where mitral dilation becomes the primary therapeutic solution, even in the absence of optimal conditions or in the presence of relative contraindications to this procedure. In these cases of complex mitral stenosis where dilation is challenging, the usual goals aiming for a significant improvement in mitral valve area after dilation are often far from being achieved.
