Indications for transcatheter mitral valve replacement based on mitral regurgitation-related research
Mitral regurgitation(MR)is the most common type of valvular heart disease.Mitral valve repair/replacement can improve the prognosis of patients with severe MR,but a large proportion of patients cannot tolerate surgical procedures due to comorbidities and surgical risks.Transcatheter mitral valve replacement(TMVR)is a kind of treatment for mitral valve disease in which an artificial valve is delivered to the mitral valve annulus through a catheter and released into place,with the advantages of no thorax opening,less trauma and high safety.Early clinical studies of TMVR have shown good results,but still face many challenges.Strict indications are effective measures to reduce surgical risks and postoperative complications.This article explores the relevant indications of TMVR by analyzing several studies at home and abroad.
