BackgroundAcute dissection of the aorta during myocardial infarction is exceptional. In such cases, fibrinolysis can be fatal.Case ReportsA 63-year-old woman with a history of hypertension was referred to our intensive care unit with the diagnosis of early stage inferior myocardial infarction. Thrombolysis was instituted and the patient rapidly developed cardiovascular collapse with global heart failure. Coronarography was attempted to revascularize the occluded coronary artery but the coronary arteries could not be catheterized. An aortography was performed and gave the diagnosis of De Bakey type I dissection of the aorta. The patient died from cardiac arrest after a phase of low cardiac output.DiscussionThis case illustrates how myocardial infarction can complicate or mask acute dissection of the aorta. It also raises the question of transthoracic echocardiography prior to institution of fibrinolysis.
