Area of Science:

  • Cardiovascular medicine
  • Medical devices
  • Interventional cardiology

Background:

  • Traditional manual contrast injection in coronary angiography involves complex stopcock-manifold systems and syringe manipulation.
  • These manual methods can be cumbersome and may limit injection precision and control.

Purpose of the Study:

  • To introduce and evaluate a novel mechanical contrast injector with an automated manifold for coronary angiography.
  • To assess the usability, image quality, and procedural efficiency of the new system.

Main Methods:

  • The study evaluated the ACIST Injection System, comprising a software-controlled syringe injector, automated manifold, hand controller, and touchscreen panel.
  • The system was tested in 50 patients undergoing diagnostic coronary angiography (n=37) or coronary interventions (n=13).

Main Results:

  • The ACIST system was easy to use across all cases.
  • It provided excellent image quality, even with multiple catheters and during stent positioning with 6Fr guides.
  • The system facilitated precision injections and expedited ventriculography.

Conclusions:

  • The mechanical contrast injector offers a user-friendly and effective alternative to manual methods.
  • It enables precise, operator-controlled injections, leading to superb coronary image quality and improved procedural efficiency.
  • The system is suitable for both diagnostic coronary angiography and interventional procedures.
