-Did he have a LIMA graft? Was it patent?

-The most prominent, and pertinent, echcardiographic finding is the severe hypokinesis of the inferior wall. This finding with the clinical presentation and the inferior ischemic changes on the EKG raises suspicion of the possibility of issues with the SVG graft to RCA (? new lesion vs. in-stent restenosis of the ostial stent).

Also, there is a mobile mass seen in RA which is probably a Chiari network or other benign finding.

Next steps: Cath (if creatinine is permissible) and TEE if you need to further delineate the RA mass.
