What is emergency coronary artery bridging?

Recently, the Department of Cardiothoracic Surgery of our hospital successfully performed emergency coronary artery bridging for a patient with acute myocardial infarction. The patient, Mr. Yao, who had three vessels bridged and suffered from severe diabetes before the surgery, has recovered successfully and will be discharged from the hospital in the next few days. Mr. Yao is 62 years old this year, after retirement has been living in Shenyang, Liaoning Province, late last month with his partner rushed to Ningbo, to visit his daughter-in-law is about to give birth to a child, the afternoon of December 26, Mr. Yao sudden anterior region of the heart tearing pain, and sweating profusely. In the evening, his family saw that his condition had not improved, and rushed him to the nearby Third Municipal Hospital, where he was diagnosed with “acute extensive anterior wall myocardial infarction” by ECG and other tests. The Department of Cardiology of the Third Municipal Hospital immediately gave him a coronary angiogram, which showed that the main blood vessels supplying the heart – the proximal part of the anterior descending branch – was 100%. The Department of Cardiology of the Third Hospital immediately performed a coronary angiogram, which showed that the main blood vessels supplying the heart – the proximal anterior descending branch was 100% occluded, the beginning of the retrograde branch was 99% narrowed and the beginning of the diagonal branch was 99% narrowed. The patient’s condition was very critical, so the hospital contacted our general duty and Director Zhao Guofang of Cardiothoracic Surgery Department, hoping that the patient would be transferred to our hospital for surgical treatment. Zhao Guofang, who was just lying down and ready to take a rest, rushed to the hospital immediately after hearing the condition and informed the operating room and anesthesiology department to prepare for the emergency surgery. At 12 o’clock that night, Mr. Yao, who had just finished coronary angiography in the Third Hospital, was transferred to our hospital. At that time, Mr. Yao’s condition was already very critical, with persistent chest pain, and his blood pressure was maintained by epinephrine and other drugs. Afterwards, anesthesiologist Hu Xukai, who was resting at home, and related personnel of the surgical team, such as Dong Caijun, Xu Peijun, Hu Yiqi, and Hong Feiyan, also rushed to the hospital from home. The patient was then admitted to the operating room. Implementing anesthesia, opening the chest to obtain the internal mammary artery, cutting the thigh to obtain the saphenous vein, establishing extracorporeal circulation, protecting the myocardium, and implementing coronary artery bridging ……, the surgery started at 2:00 a.m. and continued until dawn. Under the magnifying glass, Dr. Zhao Guofang smoothly put one internal mammary artery and two saphenous veins, bridging the diseased coronary arteries in the patient. At 6:50, the patient’s heart resumed beating, then, anesthesiologist Hu Xukai immediately gave the bedside transesophageal cardiac ultrasound examination, and saw that the patient’s heart contracted vigorously, blood pressure and cardiac output gradually rose, and all vital signs returned to normal. …… After more than 10 days of postoperative close monitoring and careful care of ICU nurses, Mr. Yao has successfully recovered, chest pain disappeared, and all indexes and indicators have been changed. After more than 10 days of close monitoring and careful care by ICU nurses, Mr. Yao has successfully recovered, his chest pain has disappeared, and he is satisfied with all the indicators, and he can be discharged from the hospital recently. Coronary heart disease is a kind of heart disease in which the coronary arteries supplying the heart are narrowed or blocked on the basis of atherosclerosis, leading to myocardial ischemia or infarction. The main manifestation is angina attack, the pain is mostly located in the chest, occasionally can also be manifested as pharyngeal, jaw and epigastric pain, early only in the labor of the symptoms, with the progression of the disease, myocardial ischemia to a certain degree, the symptoms will also appear at rest. The most serious is acute occlusion of the coronary artery lumen, and the patient can have myocardial infarction. In order to obtain a good long-term therapeutic effect, severe or multiple vascular lesions require surgical coronary artery bridging. Former U.S. President Clinton, former Russian President Boris Yeltsin, etc. have done this surgery. According to Dr. Zhao Guofang, at present, simple coronary artery bridging surgery, surgical mortality has been reduced to less than 1%, but the acute infarction patients with emergency coronary artery bridging surgery, its surgical mortality has been high, even in overseas developed countries, the surgical mortality rate is still 15 ~ 30%. Therefore, performing emergency coronary artery bridging in such patients is undoubtedly a challenge for surgeons. In a patient like Mr. Yao, one of the three blood vessels supplying the left ventricle is acutely occluded, and the other two are 99% stenotic. If any of these two vessels were to become completely occluded again, Mr. Yao would surely die. At this point, Mr. Yao was like a person who was about to fall off a cliff, his life was on the line, the only way to survive was to perform coronary artery bridging surgery immediately. Mr. Yao was suffering from severe diabetes, which undoubtedly increased the complexity and danger of the surgery. Fortunately, the surgery was performed in time, and Mr. Yao was able to survive. “The success of this surgery is a milestone in the development of cardiothoracic surgery in our hospital.” Dr. Zhao Guofang said.
