Overview

Novel PTCA survey data suggest practice variations; leaves open need for standardized appropriateness criteria.

Key Points

  • Evaluate procedural performance, appropriateness, and complication rates of percutaneous transluminal coronary angioplasty across representative European cardiac catheterization centers.
  • Audited 250 randomly selected coronary intervention cases from 25 centers across Germany, France, the United Kingdom, Belgium, and Italy performed in the first half of 1997.
  • Stratified centers by procedural volume (<300, 300–1000, and >1000 interventions per year), sampling 10 consecutive cases per center for detailed documentation review.
  • Target interventions addressed 325 stenoses in 250 cases, utilizing balloon-only angioplasty in 41% and intracoronary stenting in 54%.
  • Operators achieved procedural success in 92% of cases, while major in-hospital complications (death, emergency bypass surgery, or myocardial infarction) occurred in 4.8%.

P
Population
750 patients undergoing percutaneous transluminal coronary angioplasty across 25 centers in 5 European countries in 1997, with 250 cases analyzed for procedural outcomes.
E
Exposure
Percutaneous transluminal coronary angioplasty (PTCA), including balloon-only angioplasty (41%), stent implantation (54%), and other new devices (3%).
O
Outcome
Procedural success and major complications (composite of myocardial infarction, emergency bypass surgery, or death)safety

An audit of European PTCA practice in 1997 demonstrated a high procedural success rate (92%) and an acceptably low major complication rate (4.8%), indicating appropriate use and performance of the procedure.

Willibald Maier (1999) conducted a case-control in Coronary artery disease requiring PTCA (n=750). Percutaneous transluminal coronary angioplasty (PTCA) was evaluated on Successful procedure. An audit of randomly selected PTCA procedures across 5 European countries demonstrated a procedural success rate of 92% and a major complication rate of 4.8%.
