BACKGROUND This study was designed to examine the bulk electrical properties of myocardium and their variation with the evolution of infarction after coronary occlusion. These properties may be useful in distinguishing between normal, ischemic, and infarcted tissue on the basis of electrophysiological parameters. METHODS AND RESULTS The electrical(More)
BACKGROUND Myocardium undergoes complex cellular and histochemical alterations after acute myocardial infarction. These structural changes directly affect the mechanical stiffness of infarcted and remote myocardia. Previous investigations of infarct stiffness have been limited to uniaxial testing, which does not provide a unique description of the tissue's(More)
This is the case of a patient who presented with congestive heart failure, which appeared to be on the basis of severe mitral regurgitation secondary to granulomatous infiltration of the papillary muscles. In addition, conduction system disease and generalized myocardial involvement were documented. The patient responded well to an aggressive course of(More)
Anteroapical left ventricular aneurysms were produced in 23 sheep by coronary arterial ligation. Plication of the aneurysm does not change stroke volume or cardiac output and does not significantly change left ventricular oxygen consumption from the preoperative value of 5.1 +/- 2.6 ml/100 gm per minute. Plication, however, does increase left ventricular(More)
