Cardiac large blood vessels are mainly divided into tumor ventricular wall tumor or aortic aneurysm expansion, the symptoms are relatively mild, can be cured by surgery, if the tumor is relatively large, the anatomical location is more complex may not be able to cure. 1. Ventricular wall tumor: it is mainly a complication after myocardial infarction, usually after large myocardial infarction, myocardial cells are degenerated and necrotic and are replaced by fibrous connective tissue, which is a pathological change. Clinically, there will be chest tightness, chest pain, dyspnea, shortness of breath and other discomforts, which can be treated by surgical resection, the tumor is relatively small, and the symptoms are relatively mild, it can be clinically cured, if the tumor is relatively large, and there are serious arrhythmia, cardiac insufficiency, or those who can’t tolerate the surgery, it can’t be cured by surgery. 2. Aortic aneurysm dilatation: usually leads to aortic diameter larger than half of the normal diameter, preferably below the level of renal artery, usually due to atherosclerosis, trauma and other factors, and can be treated by surgical resection. If the condition is mild, timely diagnosis and early standardized treatment can achieve cure. If the aortic aneurysm is large and the anatomical conditions of the aneurysm are complex, it cannot be cured by surgery. When the above symptoms appear, it is recommended to go to the hospital in time for consultation and early standardized treatment.
