Crossover
= arterial access crossover from radial to femoral or vice versa, PCI =
percutaneous coronary intervention, GPIIbIIIa =
glycoprotein IIb/IIIa, IABP
= intra-aortic balloon pump.
Multivessel
disease = angiographic stenosis of at least 50% stenosis in at least two epicardial coronary arteries.
