Two-Staged Transcatheter Aortic Valve Replacement in Severely Calcified Sinotubular Junction

Key Result

A two-staged inflation method for transcatheter aortic valve replacement anchors the valve and minimizes sinotubular junction stress to improve safety in anatomically complex patients.

Key Points

• The aim is to evaluate a two-staged inflation technique for transcatheter aortic valve replacement in patients with severe calcification.
• Introduced a staged inflation approach to anchor the valve
• Focused on minimizing stress on the sinotubular junction
• Applied the method in anatomically complex cases
• The new method is simple and reproducible
• Improved safety by reducing STJ stress
• Potentially beneficial for patients with complex anatomies
