Mitral valve repair artificial mitral valve has an elevated risk of stroke. Patients with mechanical heart valves who use warfarin for anticoagulation have to be on long-term anticoagulation therapy. This means they must go to the clinic and have a lab blood draw done, typically once a month but more frequently if the level needs to be closely monitored until it is in the therapeutic range. The therapeutic range for most adults with a mechanical valve is an INR of 2.5–3.5. Finally, artificial tissue valves will wear out – on average lasting between 10 and 15 years, requiring further surgery at an advanced
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
