Cardiac catheterization
Cardiac catheterization (heart cath) is an invasive procedure threading a catheter from the arm, groin, or neck to the heart to measure pressures, image coronary arteries, and deliver treatments like angioplasty; over 1 million are done yearly in the US, and its pioneers won the 1956 Nobel Prize.
Coronary catheterization
Coronary catheterization (cardiac catheterization with coronary angiography) threads catheters from the radial or femoral artery to the heart to image coronary blockages and enable PCI; major complication rate 1.70%, radial access now preferred in ACS.
