progressive myocardial ventricular dilation, eccentric ventricular hypertrophy, and distortion of left ventricular geometry that persist in the noninfarcted myocardium after a myocardial infarction has healed. It is associated with impaired functional capacity, congestive heart failure, and premature death. Angiotensin-converting enzyme inhibitors can limit the ventricular dilation.
ventricular remodelingLeft ventricular diameter reduction Cardiovascular surgery An operative technique for CHF, which consists of excising the flabbiest portion of the dilated ventricle followed by side-to-side anastomosis; VR ↑ the pumping efficiency of the remaining tissue. See Transmyocardial revascularization.
Reshaping of heart muscle in response to injuries such as myocardial infarction, overload (hypertension), or valvular heart disease such as aortic stenosis or mitral regurgitation. Cardiac hypertrophy, fibrosis, and myocyte death are all potential consequences.
