    A 53-year-old woman presented with acute chest pain and signs of right heart compression due to a giant right coronary artery aneurysm.

  • 2

    The aneurysm measured approximately 15.6 cm and contained a significant amount of intraluminal thrombus, causing cardiac chamber compression.

  • 3

    Histopathology of the aneurysmal wall indicated non-atherosclerotic, non-inflammatory arterial wall degeneration with an unclear origin.

  • 4

    The patient underwent successful surgical resection of the aneurysm, thrombus evacuation, and bypass grafting using a saphenous vein.

  • 5

    Postoperative follow-up showed a significant decrease in central venous pressure and resolution of clinical symptoms.
