Coronary angiography Review of 1500 consecutive cases
British Heart Journal
|November 1, 1976
Summary
Coronary angiography outcomes improved significantly, with mortality dropping from 1% to 0.2% in 1500 cases. This advancement highlights the safety of experienced operators and meticulous technique in cardiac investigations.
Area of Science:
- Cardiology
- Medical Procedures
Background:
- Coronary angiography is a critical diagnostic tool in cardiology.
- Assessing the safety and efficacy of angiography procedures is essential for patient outcomes.
Purpose of the Study:
- To evaluate the safety and mortality rates of coronary angiography over time.
- To identify factors contributing to improved outcomes in cardiac catheterization.
Main Methods:
- Review of 1500 consecutive coronary angiograms performed at Harefield Hospital since 1970.
- Analysis of mortality data comparing the first 500 cases with the subsequent 1000 cases.
Main Results:
- Mortality decreased from 5 deaths (1%) in the first 500 cases to 2 deaths (0.2%) in the last 1000 cases.
- The reduction in mortality is attributed to enhanced operator training and meticulous procedural attention.
Conclusions:
- Coronary angiography, when performed by experienced investigators using the Fudkin's method, is a safe diagnostic procedure.
- New units should only commence coronary angiography services under the guidance of fully experienced personnel due to inherent risks.
