Radiation-Free Guidance for Transseptal Left Atrial Catheterization
Researchers at Children's National Hospital have developed a novel vascular sheath that contains electrodes that allow for visual access to the heart, particularly transseptal left atrial and/or ventricle access, without the use of fluoroscopy.
The American Academy of Pediatrics and American Radiologic Association have challenged the medical community to limit radiation exposure in medical imaging procedures, particularly in vulnerable populations such as children. Cardiac ablation to cure arrhythmias has become the treatment method of choice, and researchers at Children’s National have developed a new transseptal needle and guiding sheath system that allows the cardiac ablationist to safely manipulate catheters and needles into the left atrium and/or left ventricle under magnetic guidance and without fluoroscopy. Fluoro-less transseptal access could be obtained using echocardiographic techniques, but the system developed at Children’s National provides for a fluoro-free workflow that is much safer because it visualizes all apparatus components.
- Adult and pediatric populations
- Transseptal left atrial and/or ventricle access to cure arrhythmias
Stage of Development
- Prototypes of the system have been developed and tested in an in vitro bath, providing proof of concept. We are hoping to partner with a company to allow us to move to the next step of animal testing.
