"Transmural" versus "subendocardial" myocardial infarction: an electrocardiographic myth.
In 1980, Pipberger and Lopez (1) published an excellent review entitled" 'Silent' Subendocardial Infarcts: Fact or Fiction." They noted that the attempt to distinguish transmural from subendocardial infarcts on the basis of presence or absence of Q waves was not justified by any clinical, pathologic or experimental data. The authors observed that this common misconception arose from a single fl...
متن کاملDissociation between epicardial and transmural function during acute myocardial ischemia.
The relationship between epicardial and transmural function (measured with sonomicrometers) was examined in 13 anesthetized open-chest dogs. Systolic wall thickening was used as a standard of integrated transmural function to compare with epicardial function measured as segment shortening parallel to surface fibers. Three levels of coronary inflow restriction were produced by using decrements i...

متن کاملLeft Ventricular Subendocardial Ischemia
Severe valvar aortic stenosis (VAS) and supravalvar aortic stenosis (SVAS) each may cause left ventricular (LV) subendocardial ischemia and infarction, even with patent coronary arteries. LV ischemia in VAS has been related to reduced coronary perfusion relative to raised metabolic requirements, whereas this mechanism of ischemia has not been widely accepted in SVAS because coronary perfusion p...
