Background:
The use of the radial approach for diagnostic cardiac catheterization and percutaneous coronary interventions varies among different interventional cardiology centers in the world. We describe the trends in the use of this approach over the past 14 years at a tertiary hospital.
Methods:
Consecutive coronary procedures performed from 1999 to 2013 at a single center, in patients aged ≥ 35 years were identified. Age, gender, resource provider (Public or Private Healthcare System) and the complexity of the procedure (diagnostic or therapeutic) were retrospectively analyzed.
Results:
103,253 procedures were included. The Brazilian Public Healthcare Service (SUS - Sistema Único de Saúde) was the resource provider in 77% of the cases. Mean age of patients was 62.2 ± 11.3 years and 58% were male. The radial approach was used in 6,402 (6.2%) procedures, showing a significant rise over time, which was more evident when analyzed comparatively for the six timepoints of service experience: 0.2%; 0.6%; 3.1%; 2.1%; 6.9%, and 24.4% respectively (p < 0.01). Even larger percentages of radial approach were observed when only the procedures performed by the SUS and diagnostic cardiac catheterizations were taken into account. There were also changes in the profile of vascular access, even though smaller, in the Private Healthcare System.
Conclusions:
We demonstrated progressive changes in the profile of the use of access routes for diagnostic cardiac catheterization and percutaneous coronary interventions at a large center over time. These data are consistent with the global trend and are significantly robust, especially when the last sextile is analyzed.
