Mitral valve replacement The choice of which valve type to use depends upon the patient's age, medical condition, preferences with medication, and lifestyle. New Developments (2014 -2017): Transcatheter mitral valve replacement or TMVR involves human heart mitral valve replacement without recourse to open-heart surgery. TMVR treats mitral valve stenosis and/or mitral valve regurgitation leading to mitral insufficiency. TMVR, initially developed by the company Tendyne (a subsidiary of Jean Boulle Medtech Ltd) for open-heart high risk patients is expected to replace traditional mitral valve replacement surgery in the longer term. The Tendyne mitral valve is placed inside a beating heart via a transcatheter at
Mitral valve repair left atrium or lungs when the ventricle contracts (squeezes) to push blood out to the body. It has two flaps, or leaflets, known as cusps. The techniques of mitral valve repair include inserting a cloth-covered ring around the valve to bring the leaflets into contact with each other (annuloplasty), removal of redundant/loose segments of the leaflets (quadrangular resection), and re-suspension of the leaflets with artificial (Gore-Tex) cords. Procedures on the mitral valve usually require a median sternotomy, but advances in non-invasive methods (such as keyhole surgery) allow surgery without a sternotomy (and resulting pain and scar). Minimally invasive mitral valve
