Patients who have experienced myocardial infarction followed by a left ventricle aneurysm may be left with a dilated left ventricle that results in impaired systolic function. Restoring the left ventricle to its normal shape and function can be achieved via endoventricular patch plasty (EVCPP), also called the Dor procedure. Here, a Dacron patch is affixed with a circular suture to correct the aneurysm and exclude scarred areas so as to restore the ventricle’s elliptical appearance and increase its ability to pump blood out. This 20-minute procedure is usually the final part of an up-to-four hour operation called a coronary artery bypass graft. A hospital stay of just over one week may be required following the combined procedure.
