Right coronary artery with multiple giant aneurysms fistulizing into left ventricle

Coronary computed tomography angiography (CCTA) was performed to further identify the abnormality, which revealed the enlargement of the opening in approximately 3cm and diffusely dilated of RCA. The distribution of RCA could be showed graphically by the volume rendering technique (VRT) (Fig 3), which was travelling tortuously into the LV. A saccular aneurysm was found in size of about 12cm × 12cm and located in its proximal portion (Fig 4). Another giant fusiform aneurysm could be found next to the fistula. The fistula was about 2cm in diameter. Right atrium and ventricle were crushed obviously. Pericardial effusion was observed. The LCA was normal.
