OBJECTIVE Although recent experience suggests that transmyocardial laser revascularisation (TMLR) relieves angina, its mechanism of action remains undefined. We examined its functional effects and analysed its morphological features in an animal model of acute ischaemia. METHODS A total of 15 pigs were randomised to ligation of left marginal arteries (infarction group, n = 5), to TMLR of the ...
Speckle-tracking echocardiography (STE) uses a two-dimensional echocardiographic image to estimate two orthogonal strain components. The aim of this study was to assess sensitivity of circumferential (S(circ)) and radial (S(rad)) strains to infarct-induced left ventricular (LV) remodeling and scarring of the LV in a rat. To assess the relationship among S(circ), S(rad), and scar size, two-dimen...
