Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A controlled un-randomized trial where the inflammatory response in 18 patients admitted for TAVI procedure is compared to the inflammatory response in 18 patients admitted for conventional surgical valve replacement. Clinical outcomes are recorded and compared between the Groups. As a secondary endpoint, the inflammatory response was also compared between the patients receiving either transfemoral or trans aortal TAVI.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

18 patients admitted successively for conventional surgical aortic valve replacement and 18 patients admitted for transcatheter aortic valve implantation (TAVI) (9 transfemoral and 9 transaortic) are included.

A plasma sample is obtained at defined timepoints before, during and after surgery. At each time points the following biomarkers are analyzed:Concentrations of the complement activation products C3bc and the terminal C5b-9 complement complex (TCC), the neutrophil release product myeloperoxidase (MPO), the cytokines IL-6, eotaxin, MCP-1 and MIP-1β (12). As marker of a myocardial cellular injury troponin T levels will be analyzed. The following clinical outcomes will also be monitored: Death (in hospital, 30 day and one year), blood transfusion, stroke, myocardial infarction.

A dedicated registry will be established at the hospital according to the hospital's standard for storage of patient data. The registry will be deleted after completion of the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transarterial aortic valve implantation

Patients that are treated by trans arterial valve implantation (TAVI)

Group Type EXPERIMENTAL

Transarterial aortic valve implantation - TAVI

Intervention Type PROCEDURE

After insertion of a guidewire, either through the femoral artery or through the ascending aorta, the aortic ostium is dilated by a balloon and the valve is introduced through a catheter and expanded in the ostium.

Surgical aortic valve replacement

Patients that are treated by surgical aortic valve replacement (SAVR)

Group Type ACTIVE_COMPARATOR

Surgical aortic valve replacement - SAVR

Intervention Type PROCEDURE

The patient is operated through a sternotomy and coupled to a heart lung machine. The aorta is opened and the native valve excised. Then a biological artificial heart valve is sutured in place.
