The first case in the southwest!From "artificial heart" to heart transplantation

On July 6, after a routine review after the operation, the patient Luo would soon be discharged. A month ago, he successfully undergone heart transplant surgery at Huaxi Hospital of Sichuan University.

The patient had a sudden cough with difficulty breathing a year ago and seemed to seek medical treatment everywhere. He went to the West China Hospital of Sichuan University several times after he was diagnosed with expandable cardiomyopathy and inductive heart failure. Cardiac ultrasound test found that the heart contraction function (hearthrine score) is only 9%, and the contraction function of the normal human body should be greater than 50%. 9%means that the left ventricle is almost shrinking, and the blood of the whole body is almost not pumped. high. And the patient accompanied by liver and renal insufficiency caused by heart failure, in the case of maximum internal medicine treatment, the heart function is still difficult to improve, and repeated heart failure.

Based on this, the patient accepted the assessment of the heart transplant and waited for the heart transplant in the hospital. However, due to the severe scarce of potential donors and the weight of the patient's weight close to 100kg, it is almost difficult to wait for the supplier of similar weight in a short time. However, the patient's own health is getting worse and there is risk of death at any time. Fortunately, the third -generation implanted magnetic liquid suspension ventricular auxiliary device (Heartcon) developed by Aerospace Thai Heart Technology Co., Ltd., which is affiliated to the China Institute of Foam Rocket Technology Co., Ltd., was approved by the State Drug Administration and entered clinical trials.

After comprehensive evaluation and multidisciplinary consultation, Director Anqi and Dr. Wang Yabo's team of cardiac vascular surgery in the heart of the heart of the cardiac vascular surgery identified the left ventricular auxiliary device implantation surgery treatment plan to improve the function of the patient's organs, reduce the risk of waiting for the heart transplant, and continue life to continue life. Essence

On December 2, 2021, the patient successfully resettled the "artificial heart", which was also the fifth "artificial heart" surgery completed by West China Hospital. The surgery retains the heart that the patient cannot shrink. At the same time, the auxiliary device is installed in this contracted heart, and the blood is transported to the whole body organ through the new ventricular auxiliary device. Patients feel good after surgery, and symptoms of dyspnea have improved significantly.

After learning how to use equipment, how to replace the dressing, how to take a bath, and passed the assessment, the patient was discharged from the "artificial heart". The "artificial heart" device is only 180g, and can be directly put into the pericardial bag, and the wires are very small. The controller and the battery are very small, consisting of two straps, carrying the patient like a vest, very light and small, which has a small impact on the patient's daily life.

However, it was difficult to adapt to the "artificial heart". In mid -April 2022, patients felt dizzy and disgusting after lunch, and the average pressure was at a high value. The medical team conducted remote antihypertensive treatment of patients. At the same time, the ECG was monitored and found that the patient was accompanied by severe ventricular arrhythmia, and immediately arranged green channels for admission. After the relevant examination, the patient was prompted to have the risk of potentially malignant arrhythmia. Heart transplantation became his last choice, and the waiting status of the heart transplantation was also improved to a medical emergency state.

On June 18, Luo finally waited for a suitable confession. Under the collaboration of medical teams such as surgery, anesthesia, ultrasound, and in vitro circulation, he successfully completed the heart transplant and evacuated the ventricular auxiliary device. The surgery lasted more than 6 hours. After overcoming a variety of problems such as severe adhesion in the chest, difficulty in tissue structure anatomy, and difficulty in postoperative hemostasis, the surgeon team evacuated the ventricular auxiliary device and removed the previous fatigue heart. The heart recovered in the patient's body. Within 24 hours after surgery, the patient pulled out the tracheal intubation and successfully awakened. On the third day of the postoperative surgery, transferred to the general ward of the specialist after transplantation, and entered the postoperative rehabilitation stage steadily.

The recovery of patients must be grateful for the rapid development of cutting -edge technology, but also for the selfless dedication of donors. The left ventricular auxiliary device implanted the treatment for the patient to win the valuable time waiting for transplantation. Heart transplantation surgery "changed his heart" for him, allowing him to "reborn" again to continue writing his life. The success of the two operations before and after marking the comprehensive progress in the treatment technology of the West China Hospital's refractory heart failure surgical therapy. Especially for patients with excessive weight, urgent organs, and secondary pulmonary hypertension that cannot complete heart transplantation in time, the application of the ventricular auxiliary device bridge heart transplantation can comprehensively improve the treatment effect of patients with heart failure.
