Is the success rate of mitral valve replacement high

summary

Only now we can see that the medical skills of big hospitals are more and more developed, but the heart surgery still worries many people. How much is the success rate of the surgery? Let's introduce the success rate of mitral valve replacement.

Is the success rate of mitral valve replacement high

First, mitral valve replacement is a kind of thoracic and cardiovascular surgery in which the original diseased or abnormal heart valve is replaced by a prosthetic valve, and its indication is mitral stenosis or mitral regurgitation. The chordae tendineae and papillary muscle attached to the anterior leaflet were cut off at the base of the bifurcation of papillary muscle. Pay attention not to damage the chordae tendineae and papillary muscle of the posterior leaflet.

Second, MVRP should be performed only in patients with larger left ventricular end diastolic diameter. In addition, the reserved subvalvular structure should be sutured and fixed to ensure that it does not affect the mechanical valve movement. The large opening of the tilting disc valve should face the ventricular septum to avoid the possible influence of the subvalvular structure on the opening and closing of the artificial valve.

Third: at present, warfarin use and INR clinical status after heart surgery prosthetic valve replacement are at a low level. Throughout the relevant articles and conference reports in recent years, the overall average INR level is below 2.5, the incidence of thrombosis is not higher than the international level, and the bleeding rate has decreased, so the "low anticoagulation" level seems to have become a "consensus" in the industry.

matters needing attention

In fact, according to the different conditions of each patient's body, the probability of success will change, but we still need to actively cooperate with the doctor's treatment, which can also improve the probability of success and reduce the risk in the operation process.
