The CTA revealed evidence of obstructed flow in the proximal portion of the main segment of the coronary carrying the LAD and RCA (Figure 3). The patient was taken back to the operating room for CA revision.
Computed tomography angiogram (CTA) and routine angiogram images obtained after the un-roofing procedure. (A) CTA showing the aorto-coronary flap with widely patent coronary arteries. (B) Angiogram showing the aorto-coronary flap with widely patent coronary arteries. Ao, Aorta; RCA, right coronary artery; LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery.

A follow-up CTA and coronary angiogram demonstrated adequate filling of the coronary arteries with an unobstructed flow (Figure 4).
