Comparison of one-catheter strategy versus conventional two-catheter strategy on the volume of radiological contrast and diagnostic coronary catheterization performance by transradial access: A systematic review and meta-analysis of randomized clinical trials.

Background: One-catheter strategy, based in multipurpose catheters, allows exploring both coronary arteries with a single catheter. This strategy could simplify coronary catheterization and reduce the volume of contrast administration, by reducing radial spasm. To date, observational studies showed greater benefits regarding contrast consumption and catheterization performance than controlled trials.

Impact of One-Catheter Strategy with TIG I Catheter on Coronary Catheterization Performance and Economic Costs.

Background: Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access.

Objective: The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs.
