Ask Dr. Z

The left main coronary has normal takeoff from the left coronary cusp, has mild disease. The LAD is totally occluded. Left circumflex artery has a 70% very distal stenosis. The 2 obtuse marginal branches have 90% stenosis as well, and actually one of them is more like a left PDA. The RCA is a small nondominant vessel and has a 90% proximal stenosis. The left internal angiography demonstrated patent LIMA to LAD. Saphenous vein graft angiography demonstrated patent graft to the first obtuse marginal branch, and graft angiography demonstrated patent graft to the left PDA. Left ventriculography was performed with ejection fraction of 60%. Pullback from the left ventricle to the aorta did not reveal any severe stenosis.

My concernt is there is no mention of placement of catheter in bypass grafts.
