Trends in cardiac catheterization laboratories in the United States.
The Society for Cardiac Angiography and Interventions has periodically published a Directory of Cardiac Catheterization Laboratories in the United States. All known catheterization laboratories are surveyed and certain operational characteristics are queried. These surveys, in 1983, 1987, 1993, 1995 and 1998, have demonstrated a 2.5 fold increase in cardiac catheterization laboratories since 1983, corresponding increases in numbers of physicians that perform procedures, and in the numbers of procedures performed, reflecting advances in cardiovascular medicine and technology. These surveys have also documented the evolution of interventional techniques, and a shift away from film based imaging, to digitally based methods. These data provide a substrate for consideration of national cardiovascular objectives and planning of future resource allocation by cardiovascular physicians and their colleagues.
