Fig. 1 Schema of an experimental animal during data collection. A pneumatic occluder and a transit-time flow probe (AFM) were placed around the inferior vena cava (IVC) and ascending aorta (Ao), respectively. A 7F pigtail 12-pole multielectrode conductance catheter (CC) was inserted from the carotid artery into the left ventricle (LV). An echo probe (ECHO) was inserted through a subxiphoid incision into the retroperitoneal space. S, Sternum; D, diaphragm; VCO, vena cava occluder.

Fig. 2 Long-axis echocardiograms of a sheep immediately before myocardial infarction (MI) (top), 10 weeks after infarction (before aneurysm plication) (second row), immediately after aneurysm plication (third row), and 6 weeks after aneurysm plication (bottom). In each case, end-diastole is on the left and end-systole is on the right. In all frames the left ventricle (LV) is oriented so that the inferior apex is up and the aortic valve is down and to the left. The aneurysm (second row) and aneurysm plication (third row) are marked with arrows. RV, Right ventricle.
