Single Radial Access Simultaneous Left Ventricular and Ascending Aortic Pressure for the Evaluation of Aortic...

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Medical Devices

Background:

• Accurate hemodynamic assessment is crucial for managing aortic stenosis, especially in equivocal echocardiogram cases.
• Cardiac catheterization with simultaneous pressure tracings is the gold standard for evaluating aortic stenosis severity.
• Current methods may involve multiple access sites or femoral access, posing potential risks and inconveniences.

Purpose of the Study:

• To describe the first-in-man application of a novel single radial access
• double-barrel
• technique for evaluating aortic stenosis.
• To demonstrate the feasibility and accuracy of this minimally invasive approach.
• To offer an alternative to traditional methods, potentially reducing complications and improving patient comfort.

Main Methods:

• A 7-Fr Glidesheath Slender hydrophilic-coated introducer sheath was placed in the right radial artery.
• Two 4-Fr pigtail catheters were advanced through the single sheath: one into the left ventricle and one into the ascending aorta.
• Simultaneous pressure tracings were obtained for hemodynamic assessment.

Main Results:

• The single radial access "double-barrel" technique was successfully implemented in a human subject.
• Accurate simultaneous left ventricular and ascending aortic pressure tracings were obtained.
• The procedure demonstrated the potential for precise hemodynamic evaluation of aortic stenosis severity.

Conclusions:

• The single radial access "double-barrel" technique is a simple and effective method for evaluating aortic stenosis.
• This technique provides accurate hemodynamic assessment, comparable to the gold standard.
• It offers a valuable alternative to multiple access sites or femoral access, potentially improving patient outcomes.
