The patient receiving treatment is Mr. Mei, a 68-year-old retired cadre in this city. He has a history of coronary heart disease and angina pectoris for more than 20 years. He has had acute myocardial infarction three times, and many hospitals have been told that surgery is no longer possible. The patient suffered from paroxysmal ventricular tachycardia in recent two years and came to Changhai Hospital for treatment at the end of last year. Coronary angiography showed that the right coronary artery was completely occluded, the left main coronary artery was occluded 80%, and the left anterior descending branch was occluded 100%, so it was impossible to do medical intervention. Angiography also showed that he had a huge left ventricular aneurysm and his heart function was very poor. Professor Zhang Baoren, director of cardiothoracic surgery in this hospital, carefully studied the patient's condition, and after careful consideration, decided to operate on the patient.
On February 8, last year, under the guidance of the professor, Professor Zou and Dr. Chen performed three coronary artery bypass operations between the left internal mammary artery and the great saphenous vein, and removed the huge left ventricular aneurysm. This complicated operation lasted more than 4 hours and finally succeeded.
