Acute myocardial infartion due to thrombosis in coronary artery aneurysm managed by covered stent: a case report

Coronary artery aneurysm is an uncommon disease, Aneurysm when the diameter of dilatation increases more than 50% of the diameter of reference artery (normal segment). The cause can be artherosclerosis, congenital, inflammatory, connective tissue disease or Kawasaki disease. Most aneurysms detect incidentally or when complicacated. The coronary aneurysm can cause dangerous complications such as myocardial infartion, arrhythmias, compression of surrounding structures, rupture or sudden death. Medical treatment only for small, asymptomatic. Surgical treatment is basic but recently percutaneous intervention emerges by using covered stenting which is increasingly popular and has many advantages if anatomy of aneurysm is suitable. Clinical case: The clinical case we encountered was admitted to the hospital due to chest pain, low blood pressure and was diagnosed with posterior inferior myocardial infarction. Percutaneous coronary angiography showed posterior lateral branch (PLV) occlusion of the right coronary artery on the background of a coronary artery aneurysm. The patient was treated with coronary revascularization thrombectomy and successfully treated the aneurysm with covered stent placement at Hanoi Heart Hospital.
