Myocardial infarction with left ventricular wall tumor

After left ventricular myocardial infarction, the myocardium of the ventricular wall was necrotic. In about 10 to 38% of cases, the necrotic myocardium is gradually replaced by fibrous scar tissue, forming a wall tumor. The thin ventricular wall of the lesion area bulges outward, and loses its ability to move or exhibits abnormal movement when the heart contracts. As early as 1881, the evolution of coronary artery obstruction, myocardial infarction, myocardial fibrosis, and left ventricular wall tumor was fully understood. The clinical diagnosis of left ventricular ventricular aneurysm has progressed rapidly since the 1960s. In 1955 Likoff and Bailey underwent closed resection of the ventricular aneurysm. In 1958, Cooley's first ventricular aneurysm was successfully performed under extracorporeal circulation.
