Presentation
LAD vein graft occlusion suspected on coronary cath.
Patient Data
Cardiac morphology: there is a patch along a thinned left ventricular apex at the site of a prior myocardial infarct. Perfusion defect adjacent anterior septum.
Native coronaries: normal origins, right dominant. The left main artery is severely narrowed or occluded. The left anterior descending, left circumflex, and right coronary artery all have large amounts of calcified and noncalcified plaque, with areas of severe stenosis and/or occlusion.
Bypass grafts: three venous grafts are present. Patent right coronary artery graft to the posterior descending artery. Patent graft to the mid-circumflex coronary artery. Left anterior descending graft arising from the right side of the ascending aorta, occluded proximally.
Case Discussion
The two most commonly used coronary artery bypass grafts are saphenous vein and internal mammary artery grafts. Internal mammary grafts are less likely to occlude than venous grafts. In this case, the venous left anterior descending graft was occluded.
