The first one is a patient from January, a 76-year-old male with severe aortic valve insufficiency with widening of the aortic root and ascending aorta, 5.5 cm in diameter, mild to moderate mitral and tricuspid valve insufficiency, and preoperative cardiac angiography suggesting coronary artery disease with severe lesions of the left main stem and three branches. Considering that the widening of the aortic root and ascending aorta was obvious, and the ascending aorta would widen faster in a few years if left untreated, the operation was chosen to replace the aortic root (Bentall’s procedure), mitral and tricuspid valve shaping, anterior descending internal mammary artery bypass, iatrogenic branch, diagonal branch, and posterior descending saphenous vein coronary artery bypass. The operation lasted 5.5 hours, and he recovered well after the operation and was discharged from the hospital. The second patient, also a male, 71 years old, had a coronary angiogram indicating severe lesions in the left main stem and three branches, a stent implanted in the anterior descending branch of the cardiology department, a history of old infarction, cardiac ultrasound indicating moderate to severe mitral valve insufficiency, severe aortic valve insufficiency, moderate tricuspid valve insufficiency, ascending aortic widening, 4.0 cm in diameter, LVDD 7.8 cm, LAD 6.5 cm, LVEF 30%, and severe pulmonary artery bypass. LVEF 30%, severe pulmonary hypertension, ECG in sinus rhythm, and old infarction. During surgery, the left anterior ventricular wall was found to be adherent to the pericardium, and the left anterior ventricular wall was thinned but no ventricular wall aneurysm had formed, so the mitral valve and aortic valve prosthetic bioprosthesis were replaced, tricuspid valve was formed, and ascending aorta was formed. The operation lasted for 6 hours, and the patient was treated with continuous hemofiltration for one day after the operation.
