BACKGROUND After a transient ischemic episode, the subendocardial region is more severely injured than outer subepicardial layers and may regain a proportionately greater degree of mechanical function in the longitudinal direction. We sought to explore left ventricular (LV) transmural mechanics in patients with ST-segment elevation myocardial infarction(More)
Echocardiographic strain waveforms are highly variable, so their interpretation is experience-dependent and subjective. We tested whether an artificial neural network (ANN) can distinguish between strain waveforms obtained at baseline and during experimentally induced acute ischemia. An open-chest model of coronary occlusion and acute ischemia was used in(More)
Intravenous contrast agents are clinically useful for objective assessment of left ventricular (LV) regional and global function in patients with sub-optimal echocardiography images. Recent concerns over the safety of second generation microbubble contrast agents have now been largely abated with the emergence of robust clinical data supporting its safety(More)
