Comparison Between Three Types of Stented Pericardial Aortic Valves

Comparison of Short and Mid-term Hemodynamic Performance Between Three Types of Stented Pericardial Aortic Valves

This study suggests for the first time a comparison of the hemodynamic performance of the two most implanted aortic bioprosthesis in France with the new aortic bioprosthesis available since September 2010 at the University Hospital of Clermont Ferrand.

According to the French database Society for Thoracic and Cardiovascular Surgery, 11,621 patients underwent aortic valve replacement in 2007. Over 77% of biologic prosthetic valves were used. Among these biologic valves, those in pericardium are mainly used in all French cardiac surgery centers.

Since March 2010, a new pericardial aortic valve has obtained a CE mark, allowing cardiac surgery centers in Europe to implement it in humans.

Hemodynamic performance of different biologic valves has never been measured. This study suggests for the first time a comparison of the hemodynamic performance of the two most implanted aortic bioprosthesis in France with the new aortic bioprosthesis available since September 2010 at the University Hospital of Clermont Ferrand.

Inclusion Criteria:

• Patients aged between 18 and 85 years who need aortic valve replacement (no endocarditis) With Bioprosthesis, with or without myocardial revascularization, with or without tricuspid valve repair surgery

Exclusion Criteria:

• no endocarditis
