Term: Percutaneous Coronary Interventions (PCI) / Angioplasty

Glossary Definition

Last Updated: 2020-05-21


Percutaneous coronary interventions (PCI) include percutaneous transluminal coronary angioplasty (PTCA) procedures, commonly known as "angioplasty" or "balloon angioplasty". These procedures treat the narrowed coronary arteries of the heart often found in people with coronary heart disease. Angioplasty procedures use a balloon-tipped catheter to enlarge a narrowing in a coronary artery and, if necessary, a small lattice-shaped metal tube called a stent is inserted permanently into the artery to help hold it open so blood can flow through it more easily.

PCIs were identified using ICD-9-CM procedure codes 36.01, 36.02, 36.03, 36.05, 36.06, and 36.07 or CCI codes 1.IJ.50 and 1.IJ.57 in any procedure field in a hospital discharge abstract (inpatient or outpatient). NOTE: The ICD-9-CM codes listed here are a correction to the information originally published in the RHA Indicator Atlas 2009 report.

The definition is restricted to residents aged 40 and older.

PCI procedures were only performed at the two tertiary hospitals (Health Sciences Centre and St. Boniface General Hospital), so only hospital separations from these two hospitals were included in the analysis in order to eliminate the potential for double-counting of procedures.
