Multiple thrombosis caused by arrhythmogenic right ventricular cardiomyopathy

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Cardiac Surgery

Background:

• Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic heart muscle disease.
• Intracardiac thrombosis is a serious complication, often associated with conditions causing blood stasis or endothelial dysfunction.

Observation:

• A 68-year-old male presented with multichamber intracardiac thrombosis.
• Enhanced computed tomography (CT) identified thrombosis in the right atrial appendage, right ventricular outlet tract, and left atrial appendage.
• A localized aneurysm of an enlarged right ventricle was also noted.

Findings:

• The patient was diagnosed with arrhythmogenic right ventricular cardiomyopathy.
• Multichamber intracardiac thrombosis was confirmed as a rare manifestation.
• The enlarged right ventricle with localized aneurysm likely contributed to thrombus formation.

Implications:

• This case highlights the importance of advanced imaging in diagnosing complex cardiac pathologies.
• Understanding the association between ARVC and extensive thrombosis can improve patient management strategies.
• Surgical intervention, including thrombectomy and valve repair, can be effective in managing such rare presentations.
