Insights
A mechanical heart valve thrombosis caused a myocardial infarction in a 32-year-old man. Despite treatment, reoperation was needed for valve replacement and bypass grafting.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Biomedical Engineering
Background:
- Mechanical heart valves, such as the Medtronic-Hall prosthesis, are used to treat valvular heart disease.
- Thrombosis of mechanical heart valves can lead to serious complications, including myocardial infarction.
- Early detection and management of mechanical heart valve thrombosis are crucial for patient outcomes.
Abstract:
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).
