Using fluoroscopy, the cardiologist inserts catheters into one or both sides of the heart and measures pressures and cardiac output. The cardiologist also may obtain blood specimens for oxygen saturation testing. By injecting contrast media, the cardiologist can further define cardiac structures, including the coronary arteries, and assess cardiac wall motion. Depending on the facility and the patients condition, cardiac catheterization may be performed as either an inpatient or an outpatient procedure.

Indications for cardiac catheterization include definitive or suspected myocardial ischemia, syncope, valvular heart disease, and acute myocardial infarction (MI). It also may be indicated after an MI, coronary artery bypass graft sur...
