2024年4月16日 · Mitral valve repair and mitral valve replacement are types of heart surgery to fix or replace a leaky or narrowed mitral valve. The mitral valve is one of four heart valves that control blood flow in the heart. It's located between the upper and lower left heart chambers.

Mitral valve regurgitation is the most common type of heart valve disease. In this condition, the valve between the left heart chambers doesn't close fully. Blood leaks backward across the valve. If the leakage is severe, not enough blood moves through the heart or to the rest of the body.

Mitral valve replacement is a heart surgery to give you a new mitral valve when your current one can’t be repaired. Your new valve will be either mechanical or biological. This surgery can relieve symptoms of mitral valve disease and prevent further damage to your heart.

Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [1] Causes of mitral valve disease include infection, calcification and inherited collagen disease.

Transcatheter mitral valve replacement (TMVR) is a procedure to replace a heart valve. TMVR implants a manufactured valve or one made from biological heart tissue. The human-made valve then does the work of the faulty mitral valve. It’s a less invasive option than open-heart surgery to correct mitral valve stenosis or regurgitation.

TMVR is a minimally invasive structural heart disease treatment to replace a damaged mitral valve without open-heart surgery. A flexible, hollow tube (catheter) is inserted through a blood vessel to reach the heart and replace the mitral valve. There are two types of TMVR techniques:

1998年11月3日 · Mitral valve replacement (MVR) is an accepted surgical procedure for patients with severe MS who are not candidates for surgical commissurotomy or percutaneous mitral valvotomy. The risk of MVR is dependent on multiple factors, including functional status, age, LV function, cardiac output, concomitant medical problems, and concomitant CAD.

2017年12月27日 · TMVR transcatheter mitral valve replacement is a treatment for mitral valve stenosis (tight mitral valve) or mitral valve regurgitation (leaky mitral valve) or a mix of the two. TMVR transcatheter mitral valve replacement was developed initially as a method of replacing the mitral valve in patients considered too high risk for surgery but will ...

2017年4月28日 · Transcatheter mitral valve replacement (MVR) has recently emerged as an exciting new frontier in the field of cardiac structural interventions. Although transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with symptomatic severe calcific aortic stenosis, the experience with transcatheter MVR remains ...

Numbers of multiple valve surgery are 28% of all valve surgery performed. Combined MVR and AVR is performed most often (12.5%) among multiple valve operations followed by MVR and tricuspid valve repair. Rheumatic is the most common pathology (74%) in multiple valve surgery.
