The double-tap technique improves transcatheter aortic valve replacement (TAVR) by reducing pressure gradients and increasing valve diameter. This method enhances balloon-expandable transcatheter heart valve (THV) expansion, leading to better hemodynamic outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Transcatheter aortic valve replacement (TAVR) is a common procedure for aortic stenosis.
- Optimizing transcatheter heart valve (THV) expansion is crucial for successful TAVR outcomes.
- The double-tap technique, using the original delivery system balloon, has been proposed to improve THV expansion.
