The cardiac pigtail catheter

Area of Science:

• Cardiovascular medicine
• Medical device technology
• Interventional cardiology

Background:

• Accurate contrast medium delivery is crucial for cardiac imaging and interventions.
• Existing catheters may pose risks of intramyocardial injection or unstable positioning.

Purpose of the Study:

• To describe a novel curved catheter with a pigtail tip.
• To evaluate its efficacy in contrast medium delivery to cardiac structures and great vessels.
• To assess its safety and ease of placement in various cardiac locations.

Main Methods:

• Description of a newly designed curved catheter with a pigtail tip.
• Evaluation of catheter performance in delivering contrast medium retrogradely to the left ventricle, aorta, and pulmonary arteries.
• Assessment of catheter positioning in the right ventricular apex.

Main Results:

• The pigtail catheter enables stable and rapid contrast medium delivery.
• The catheter self-positions in an ectopic free position in the left ventricle when used retrogradely.
• The catheter can be safely advanced into the right ventricular apex without risk of intramyocardial injection.

Conclusions:

• This pigtail catheter design facilitates precise and secure contrast delivery.
• The catheter's properties enhance procedural safety by minimizing risks associated with placement.
• It represents an advancement in cardiac catheterization tools for improved diagnostic and interventional outcomes.
