Cavernous hemangioma of the right atrium: presumptive diagnosis by coronary angiography

Area of Science:

• Cardiovascular Imaging
• Interventional Cardiology
• Cardiac Pathology

Background:

• Vascular tumors of the heart are uncommon, presenting diagnostic challenges.
• Right atrial tumors require detailed vascular supply assessment for accurate characterization.

Purpose of the Study:

• To describe the angiographic features of a unique vascular tumor located in the right atrium.
• To illustrate the complex vascular supply of this specific cardiac tumor.

Main Methods:

• Case report detailing a patient with a right atrial vascular tumor.
• Angiography was utilized to visualize tumor vascularity and feeding arteries.
• Contrast material retention was assessed during imaging.

Main Results:

• The vascular tumor was supplied by vessels originating from both the right and left coronary arteries.
• Angiography demonstrated significantly dilated blood spaces within the tumor.
• Persistent contrast material retention was observed in these spaces, indicating abnormal vascularity.

Conclusions:

• This case highlights an unusual vascular tumor of the right atrium with a dual coronary artery supply.
• Angiographic findings underscore the importance of comprehensive vascular assessment in cardiac tumors.
• The persistent contrast retention suggests specific hemodynamic properties of the tumor's vasculature.
