Angiogram showed a critical LAD thrombotic stenosis. The patient went to cath and had a distal LAD 99% stenosis with thrombus and TIMI-2 flow. After many hours, the decided that it was appropriate to do an angiogram and they found a distal LAD occlusion which was opened and stented. Why bradycardia? It was stented.
