Coronary embolism following aortic and mitral valve replacement: successful management with abciximab and urokinase
1Internal Medicine Residency Program, University of Hawaii, Honolulu, USA.
Insights
Coronary embolism caused acute myocardial infarction in a patient with prosthetic heart valves. Treatment with angioplasty, urokinase, and abciximab successfully resolved the emboli.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Prosthetic heart valves, such as St. Jude aortic and mitral valve replacements, can be associated with embolic complications.
- Coronary embolism is a rare but serious cause of acute myocardial infarction.
Observation:
- A 63-year-old woman with St. Jude aortic and mitral valve replacements presented with acute myocardial infarction.
- Cardiac catheterization revealed a saddle embolus in the circumflex and ramus arteries and another embolus in a diagonal branch.
Findings:
- Angioplasty was performed for the occluding diagonal branch embolus.
- A combined regimen of intracoronary urokinase and intravenous abciximab achieved complete resolution of the coronary emboli.
Implications:
- This case highlights a successful treatment strategy for coronary embolism in patients with prosthetic heart valves.
- The findings suggest that a combination of interventional and pharmacological approaches can effectively manage this critical condition.
- Further research may explore optimal anticoagulation and thrombolytic strategies in this patient population.
Abstract:
We report a case of coronary embolism in a 63-year-old woman with St. Jude aortic and mitral valve replacements who presented with acute myocardial infarction. Urgent catheterization revealed a saddle embolus in the proximal part of the circumflex and ramus arteries and another embolus in a diagonal branch. After employing angioplasty for the totally occluding diagonal embolus, a combined regimen of intracoronary urokinase and intravenous abciximab was successful in achieving complete resolution of the emboli.
