Coronary and atrial compression by a giant cardiac hemangioma

Area of Science:

• Cardiology
• Oncology
• Pathology

Background:

• Heart hemangiomas are rare benign tumors.
• They are typically asymptomatic but can cause complications if they grow.
• Early detection and intervention are crucial for managing cardiac tumors.

Observation:

• A 57-year-old male presented with an asymptomatic round, echo-dense mass in the left atrium.
• Magnetic resonance imaging (MRI) localized the mass to the atrioventricular groove within the pericardial space.
• Computed tomography (CT) revealed compression of the left main coronary artery and left pulmonary veins.

Findings:

• Surgical removal of the mass was performed.
• Histopathological diagnosis confirmed the tumor as a hemangioma.
• The patient's asymptomatic presentation contrasted with the critical vascular compression observed.

Implications:

• This case highlights the importance of investigating cardiac masses, even in asymptomatic individuals.
• Prompt surgical intervention can prevent life-threatening complications from cardiac hemangiomas.
• Understanding the potential for rapid growth and vascular compromise is key in managing these rare tumors.
