Who needs a heart transplant?

Heart transplantation is the third most common organ transplantation operation in the United States (the first and second are corneal transplantation and renal transplantation respectively), and more than 65,438+0,500 patients in the United States receive heart transplantation every year. A healthy heart comes from the brain death of organ donors. The removed heart is kept in a special salt solution. After general anesthesia, the doctor made an incision between the patient's chest and sternum. When the blood supply to the heart is interrupted, the patient's blood is transported to the cardiopulmonary bypass device through the artificial pipeline to temporarily replace the patient's cardiopulmonary function and maintain the normal oxidation and circulation of the patient's blood. During the operation, the patient's heart was removed and the donor's heart was sutured back to the patient's chest. Heart transplantation can prolong the life of patients with severe heart disease. About 80% patients can survive for 2 years after operation. Like other organ transplants, the biggest problem of heart transplantation is transplant rejection. If the transplant rejection is controlled, the survival time of patients can reach 10 years or more. Patients need to take immunosuppressants irregularly after operation. When the patient feels better, he can carry out appropriate daily activities under the guidance of a doctor. But avoid strenuous physical labor. Heart transplantation is suitable for heart failure caused by the following factors: 1 Coronary atherosclerotic heart disease. Primary cardiomyopathy III. Congestive heart failure caused by heart valve disease. Heart transplantation is prohibited in patients with severe congenital heart disease complicated with the following diseases: 1. Kidney, lung and liver diseases. Insulin-dependent diabetes 3. Schematic diagram of heart transplantation for other life-threatening diseases.
