Unremitting embolus from cardiac myxoma at circumflex artery trifurcation

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Pathology

Background:

• Embolisation of coronary arteries by cardiac myxoma is a rare event.
• The natural history of myxomatous emboli within the coronary arteries following myocardial infarction is not well-understood.
• Understanding embolus behavior is crucial for determining optimal surgical intervention strategies.

Observation:

• A case of embolisation to the circumflex artery trifurcation from a left atrial myxoma is presented.
• Coronary angiography was performed 6 months post-myocardial infarction to assess the embolus's course.
• The myxomatous embolus was observed to be unremitting in its presence.

Findings:

• The myxomatous embolus within the coronary artery did not spontaneously resorb or significantly change its morphology over 6 months.
• This observation contrasts with previous case reports suggesting potential resorption or arterial wall integration.
• The embolus persisted without evidence of degradation or significant alteration.

Implications:

• The unremitting nature of myxomatous emboli suggests that surgical or interventional removal may be necessary.
• This finding impacts the management strategy for patients with cardiac myxoma and coronary artery embolism.
• Further studies are warranted to elucidate the long-term fate of coronary myxomatous emboli.
