Preservation of Myocardial Perfusion and Function by Keeping Hypertrophied Heart Empty and Beating for Valve Surgery: An In Vivo MR Study of Pig Hearts

Figure 2

LV wall hypertrophy originated from aorta banding. (a-b) LV of aorta banding animals had thicker wall in comparison with sham operation animals. (c-d) LV end-diastolic and end-systolic wall thicknesses were substantially greater in aorta banding animals than in sham operation animals. The approximately eight-week banding period was sufficient to induce LV wall hypertrophy. versus sham operation. versus 28 or 58 days.
