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 stenosis left atrium correlates with the severity of the mitral stenosis. As the severity of the mitral stenosis increases, the pressure in the left atrium increases, and the mitral valve opens earlier in ventricular diastole. A mid-diastolic rumbling murmur with presystolic accentuation will be heard after the opening snap. The murmur is best heard at the apical region and is not radiated. Since it is a low-pitch sound, it is heard best with the bell of the stethoscope. Its duration increases with worsening disease. Rolling the patient toward left as well as isometric exercise will accentuate the murmur. A thrill might
