Coronary artery aneurysm (CAA) is a relatively rare disease that may cause
angina, myocardial infarction, sudden death due to thrombosis, embolisation
, or rupture. This report describes the case of a man aged 65 years old who
had an anterior myocardial infarction due to left anterior descending arte
ry (LAD) aneurysm. We attempted early percutaneous transluminal coronary an
gioplasty (PTCA) for treatment of acute myocardial infarction, but were not
successful. He was then treated with intracoronary streptokinase. Serial c
oronary angiographies showed recanalisation and aneurysm on the LAD. The pa
tient was operated on with coronary bypass surgery, and treated with an ora
l anticoagulant, nitrate, and blocker. He was well after one year of follow
-up.
