Surgical Treatment of Aortic Stenosis With a Next Generation Surgical Aortic Valve

Surgical Treatment of Aortic Stenosis With a Next Generation Surgical Aortic Valve

The purpose of this clinical investigation is to confirm that the safety and performance of the EDWARDS INTUITY Valve System.

This is a two-phase, non-randomized, prospective, single arm, multi-center clinical investigation. Each subject in Phase 1 and Phase 2 is consented for a period of 5 years. All subjects will be assessed for clinical follow-up at the following intervals: Discharge, 1 month, 3 months, 1 year and annually thereafter until 5 years of follow-up is achieved per subject.

Criteria:

Inclusion Criteria:

• Aortic stenosis or stenosis-insufficiency of aortic valve requiring a planned replacement as indicated in the preoperative evaluation;
• Scheduled to undergo planned aortic valve replacement with or without concomitant coronary bypass surgery, MAZE procedure, septal myectomy, pacemaker/ICD implant and or atrial appendage occlusion/removal.
• Signed and dated the informed consent form prior to investigation procedures;
• Geographically stable and agrees to attend Follow up assessments at the hospital of surgical services for a maximum of 5 years.
