What are the sequelae of mitral valve replacement

summary

Most of the time, you know that surgery is risky, but you still have to have surgery, because if you don't have surgery, you may not have a chance to survive, so you can continue your life through surgery. Let's talk about the sequelae of mitral valve replacement.

What are the sequelae of mitral valve replacement

First, left ventricular rupture after mitral valve replacement is very rare and often fatal. When the left ventricular wall is weak, excessive resection or traction of the papillary muscle may cause left ventricular rupture. If there is acute or subacute myocardial infarction, especially in elderly patients, left ventricular rupture may also occur.

Second, the advanced surgical method of preserving the integrity of mitral subvalvular structure can reduce the incidence of complications of left ventricular rupture. The treatment for heart rupture includes immediate re establishment of cardiopulmonary bypass. After removal of the artificial valve, the perforation was repaired by suture of bovine pericardium and left ventricular intima, and then the artificial valve was implanted.

Third, if left ventricular rupture is found in the operating room after cardiopulmonary bypass, the prognosis is poor. What happens in the ICU is often fatal. Excessive removal of calcified lesions in the posterior mitral valve and annulus may lead to hematoma in the atrioventricular sulcus, atrioventricular separation or cardiac rupture. If the suture is too deep on the posterior annulus, the circumflex artery may be damaged.

matters needing attention

Although there are many sequelae of mitral valve replacement, as long as patients can be reasonably nursed, these sequelae can not occur. Therefore, patients do not need to be too anxious, because the more anxious they are, the more unfavourable they may be to the treatment of the disease. This is a point that every patient should be aware of.
