Third-Generation Transcatheter Aortic Heart Valve with Reverse Parachute Sealing Cuff in Patients with Aortic Valve...

Area of Science:

• Cardiology
• Interventional Cardiology
• Biomedical Engineering

Background:

• The Navitor is a novel, third-generation, self-expanding transcatheter heart valve designed to reduce paravalvular regurgitation (PVR).
• Limited clinical data exists on the real-world application of the Navitor system due to its recent introduction.

Purpose of the Study:

• To evaluate the clinical, hemodynamic, and safety outcomes of the Navitor transcatheter heart valve in a consecutive, as-treated patient cohort.
• To assess the efficacy of the Navitor system in mitigating paravalvular regurgitation in a non-clinical trial setting.

Main Methods:

• A consecutive cohort of 60 non-clinical trial patients treated with the Navitor system was analyzed.
• Data collected included procedural success, patient demographics, safety events, and paravalvular regurgitation at 30 days post-procedure.

Main Results:

• All 60 patients underwent successful procedures with favorable outcomes at 30 days.
• No heart failure readmissions occurred; major vascular complications (1.7%) and new pacemaker implantation (7.14%) were low.
• Paravalvular regurgitation (PVR) was trivial or none in 75% of patients, with no cases of severe PVR.

Conclusions:

• The Navitor system showed favorable clinical, hemodynamic, and safety outcomes in this as-treated cohort.
• The results suggest the Navitor is a promising option for transcatheter aortic valve replacement, particularly in managing PVR.
