Dedicated radial ventriculography pigtail catheter.

Area of Science:

• Cardiology
• Medical Device Design
• Interventional Radiology

Background:

• Traditional cardiac ventriculography often utilizes femoral arterial access.
• Radial and upper arm arterial access present unique anatomical challenges for catheter manipulation.
• Existing catheters may not optimally address the diverse anatomical variations encountered in patients.

Purpose of the Study:

• To introduce a new dedicated cardiac ventriculography catheter system.
• To design catheter configurations specifically for radial and upper arm arterial access.
• To improve catheter performance, ease of use, and patient outcomes during ventriculography.

Main Methods:

• Development of two distinct catheter configurations: "short" and "long" versions.
• Design focused on facilitating retrograde aortic valve crossing and adapting to various anatomies.
• Evaluation of catheter suitability for different patient body types and ascending aortic orientations.

Main Results:

• The "short" catheter is optimized for horizontal aortas, obese patients, and small ventricles.
• The "long" catheter is suited for vertical aortas, thin patients, and larger ventricles.
• The new design demonstrated stable performance during contrast injection, achieving comparable opacification to traditional catheters.

Conclusions:

• The new dedicated radial ventriculography catheter offers tailored configurations for diverse patient anatomies.
• This design facilitates faster, simpler left ventricular insertion, potentially reducing procedure time and radiation exposure.
• The catheter provides stable performance and effective opacification, representing an advancement in radial access cardiac procedures.
