2. ECG 30 min after presentation at the tertiary cardiac hospital
revealing normal ST segment and sinus rhythm.
A decision was made to proceed with invasive coronary intervention due
to the nature of the pain and ECG changes. The result revealed normal
blood flow in the coronary arteries. However, a sac was observed behind
the ascending aorta, aortic arch, and descending aorta, compressing the
coronary arteries, mainly the right coronary artery (RCA), resulting in
inferior STEMI (Figure 3)
