[Coronary embolism disclosing thrombosis on a Medtronic-Hall aortic valve prosthesis in aortic position].
A 32 year-old-man admitted to hospital on the third day of myocardial infarction, three months after aortic valve replacement with a mechanical Medtronic-Hall prosthesis. The embolic character of the disease was evident on coronary angiography which showed a large thrombus in the left main coronary artery. The thrombosis of the valve prosthesis was not detected by non-invasive investigations but at aortography, confirmed at surgery. Thrombolysis with rt-PA did not dissolve the clot and reoperation was necessary (valve replacement with aorto-coronary bypass grafting).
