Percutaneous transvenous mitral commissurotomy for mitral stenosis patients with markedly severe mitral valve deformity: Immediate results and long-term clinical outcome

In conclusion, to evaluate the efficacy and safety of PTMC for mitral stenosis patients with markedly severe valve deformity, we performed PTMC in 17 patients with severe mitral stenosis assessed by echocardiography (echo score ≥12). This study demonstrates that PTMC can be performed safely and is clinically useful in treating the mitral stenosis patient with a markedly severe valve deformity.
