MODIFIED ENDOVENTRICULAR CIRCULAR PLASTY (DOR PROCEDURE) IN A PATIENT
PRESENTING WITH ACUTE SHORT-TERM MEMORY LOSS
OVERVIEW A long-term complication of acute myocardial infarction (AMI)
is an aneurysm of the left ventricle (LV) resulting mostly in cardiac
failure, ventricular tachycardia (VT), and thromboembolic episodes.
Post-infarction LV aneurysm results in LV dilatation and abnormal
geometry leading to systolic and diastolic dysfunction. Sudden cardiac
death often results from VT after AMI. Conventional surgeries like
coronary artery bypass alone have been shown to have minimal benefits in
patients with cardiac failure. In a prospective 10-year follow-up study
on survival after myocardial revascularization for ischaemic
cardiomyopathy, Shah et al reported that coronary artery bypass grafting
(CABG) alone after ischaemic heart disease and low left ventricular
fraction results in relief of angina symptoms. This particular case was
quite interesting because of its unusual presentation and also the
progression of symptoms with the attendant deterioration of LV function.
