Mitral regurgitation is the most common heart valvular disease at present. In the past, mitral regurgitation was mainly treated by surgical mitral valve repair or replacement. However, with the progress of transcatheter interventional techniques and instruments in recent years, transcatheter mitral valve interventional therapy has gradually shown its advantages and benefited patients. The purpose of this article is to review the progress of transcatheter mitral valve intervention in this year, and to provide prospects for the future of transcatheter mitral valve treatment.
[Abstract]A 70-year-old woman who was admitted to the hospital for post-cardiac surgery panic attack for 4 months. Eight months ago, she was admitted to a local hospital with 7 years of post-activity panic, which worsened for 2 months, and underwent mitral valve replacement+aortic valve replacement+tricuspid valvuloplasty+modified maze procedure+left auriculotomy. Four months after the operation, mitral valve damage appeared, and transcatheter mitral valve replacement was performed in our hospital by apical approach. A case report on the treatment of this patient is presented.
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.
In recent years, transcatheter mitral valve replacement is a focused issue in the field of valve intervention, which brings hope to mitral regurgitation patients who are not suitable for surgical thoracotomy. This paper presents the case of echocardiography-guided transseptal mitral valve replacement with the HighLife system in an elderly female patient with severe mitral regurgitation who failed to respond to standard medical therapy. During the procedure, echocardiography was used to guide the wire looping, cinching, atrial septal puncture, ring closure, atrial septal balloon dilatation, prosthetic valve implantation and immediate postoperative evaluation. Echocardiography plays an important role in transseptal mitral valve replacement, which can help the procedural process and improve the safety of the procedure.
Mitral regurgitation is the most common cardiac valve disease, with high rates of morbidity and mortality. Transcatheter mitral valve replacement (TMVR) is used as a promising intervention in non-surgical patients and in those with unsuitable anatomy for transcatheter edge-to-edge repair. TMVR can also be performed for inoperable or high-risk patients with degenerated or failed bioporstheses or failed repairs, or in patients with severe annular calcifications. The complex anatomy of the mitral valves makes the design of transcatheter mitral valve prostheses extremely challenging, and increases the difficulty of TMVR procedure, thus could led to non-negligible complications including periprocedural and post-procedural long-term complications. This review aims to discuss the potential TMVR-complications and measures implemented to mitigate these complications, in order to improve the prognosis of TMVR patients.
