Making this feasible has been the arrival of automated contrast injectors which permit improvements in angiographic image resolution. <br \/>Typically, smaller catheters in use today are 5 Fr. Sheathless catheters promise to reduce the miniaturization envelope even further, since the catheter sheath typically adds 1-2 Fr in diameter. In such circumstances, some foresee a future with what are effectively equivalent to 3 Fr interventions based on a 4 or 5 Fr sheathless catheter.<\/p>\n<p><strong>Cardiologists divided over smaller catheters<\/strong><br \/>However, there is still doubt about the impact of smaller catheters on procedural efficiency and outcomes.
