Anomalous coronary anatomy is demonstrated, with both the right and left coronary arteries arising from a large common trunk off the right coronary cusp.
Right coronary artery is large, with minor proximal tortuosity prior to otherwise a normal course along the right AV groove. Moderately large posterolateral branch. Moderate PDA to the apex. Minor calcific plaque at the proximal RCA and proximal PDA. Minor non-calcified plaque at the distal RCA prior to its bifurcation. None of these are stenosing (<50%)
The left coronary artery does not have an acute angle take off, but has an acute angle turn soon after its origin, where it takes an anomalous course between the pulmonary outflow tract and aortic root. After giving rise to some septal branches, it courses posterior to the anterior interventricular groove, gives off a moderate size branch that courses along the interventricular groove LAD before bifurcating an anterior branch that gives rise to 2 large diagonal branches, and a posterior branch that becomes the circumflex after giving off another large diagonal branch. The circumflex after giving off the OM1 becomes very small.
Non stenosing (<50%) mixed plaque at the distal LCA prior to its terminal bifurcation. Non calcific nonstenosing plaque at the proximal circumflex. Minor calcific plaque at the circumflex just prior to OM1.
Tiny arterial branch arises from the left cusp with a short course between the left atrial appendage and right pulmonary outflow tract.
Heavy calcification of the aortic valve, possibly bicuspid. The LV wall appears thickened.
Anomalous coronary anatomy with a right coronary cusp common trunk origin of the RCA and LCA, with LCA having a malignant inter-arterial course between the pulmonary outflow tract and aortic root.
