Coronary angioplasty (PTCA: percutaneous transluminal coronary angioplasty) is a procedure that opens up narrowed or blocked coronary arteries using a balloon. Often a metal tube (stent) is fitted as well. Coronary angioplasty can be used to treat angina pectoris and heart attacks. The Swiss Atlas of Healthcare contains analyses on the frequency of coronary angioplasties in total and separate analyses on inpatient and outpatient settings.
