Clinicopathological evaluation in the surgical treatment for ischemic heart disease.
Discrepancy in coronary stenosis between angiogram and pathological specimen was moderately found. It is of a problem what is meaning by a significant narrowing. Coronary capacity per heart weight markedly reduced in multi-vessel disease and revealed an intimate relationship to sudded death and cardiac failure. Much of sclerosis in the arterial wall was relatively severe in spite of patency in lumen of the terminal artery. Intramuscular arterioles were intact even when severe extramuscular coronary atherosclerosis was seen. Well-developed collaterals were seen in much of multi-vessel disease. Muscle prevervation was relatively good even in the advanced sclerosis. It is reasonable to make an attempt on a newly construction of a vessel to introduce into preserved arteriola with well-developed collateral, and preserved myocardium.
