Complex cardiac vascular malformation: Natures own CABG.

True cardiac arteriovenous malformations are rare anomalies that may be acquired or congenital in origin. These anomalies are well demonstrated by Multi Detector Computed Tomography (MDCT) with much higher clarity and anatomic detail than invasive angiography. We report a case of large complex cardiac vascular malformation in 55 year old male involving feeders from systemic (internal mammary artery, right inferior phrenic artery), coronary (left anterior descending), and pulmonary arterial and venous systems using a 64 slice MDCT scanner.
