The training for and practice of percutaneous transluminal coronary angioplasty: results of two surveys.
In order to gain understanding of how percutaneous transluminal coronary angioplasty (PTCA) is taught and practiced in the United States, two questionnaires were devised to survey all adult cardiology training programs and all adult cardiac catheterization laboratories in this country. Of the 184 programs that responded to the training questionnaire, 102 (55%) teach PTCA, usually in the form of fellowship training and especially as a specialized year, and less commonly in the form of a preceptorship. Though many programs expose trainees to an adequate number of cases as defined by the program directors, at least 37% do not. Of 388 laboratories responding to the practice questionnaire, 74% perform PTCA. The total number of PTCA's in this country seems to be doubling yearly, but many laboratories do relatively few cases per year, and 79% of physicians doing PTCA do fewer than one case per week. Average laboratory success rate for PTCA is in the range of 80-85%. Though there is now a proliferation of PTCA training programs, 93% of those practicing angioplasty are self- or preceptor-trained, and have not learned the procedure as part of a fellowship.
