Angiographic and pathologic evidence of hemorrhage into the myocardium after coronary reperfusion
Insights
Reperfusion therapy for myocardial infarction can cause severe myocardial hemorrhage. Angiographic contrast extravasation indicates hemorrhage, requiring attention to prevent further bleeding.
Area of Science:
- Cardiology
- Interventional Cardiology
- Pathology
Background:
- Reperfusion therapy is crucial for evolving myocardial infarction.
- Myocardial hemorrhage is a potential adverse effect of reperfusion.
- Early identification of hemorrhage is vital for patient outcomes.
Observation:
- A case report of an 83-year-old man undergoing reperfusion therapy.
- Angiographic evidence showed contrast medium extravasation from the right coronary artery.
- This extravasation occurred into the inferoposterior left ventricular wall.
Findings:
- Autopsy confirmed severe, transmural hemorrhage in the inferoposterior left ventricular wall.
- Contrast extravasation on angiography is a direct sign of myocardial hemorrhage.
- This finding is associated with the production of hemorrhage during coronary reperfusion.
Implications:
- Angiographic contrast extravasation is a critical sign of myocardial hemorrhage.
- Clinicians must recognize this sign during coronary reperfusion therapy.
- Prompt identification can help prevent further hemorrhage and improve patient management.
Abstract:
Severe myocardial hemorrhage can occur as a potential adverse effect of reperfusion therapy in evolving myocardial infarction. This report describes a 83-year-old man, who showed angiographic evidence of extravasation of contrast medium from the reperfused right coronary artery into the inferoposterior left ventricular wall. At autopsy, severe hemorrhage was transmurally observed in the inferoposterior wall of the left ventricle. The finding of extravasation is a useful angiographic sign of the production of hemorrhage during coronary reperfusion therapy, and great attention should be focused to the existence of this sign to prevent further hemorrhage.
