Case Discussion

Patient with STEMI due to a occlusion of the middle segment of the right coronary artery. As another finding, conventional angiography showed common ostium of both coronary arteries at the right coronary sinus and a "malignant" course has been suspected.

The prospective ECG-triggered CTA of the coronaries shows the common origin out of the right coronary sinus and the so called interarterial course of the LCA between the aortic root and the pulmonary trunk.

This anomaly is called a "malignant" course because it is associated with a higher risk of caridac ischemia and sudden cardiac death.

Coronary bypass surgery is planned.
