Introduction

•Aortic valve repair using a pericardial patch has become an attractive alternative to aortic valve replacement
•Commercially, there are several pericardial patches available, which are prepared differently
•Little clinical evidence exists in determining which pericardial patch would be optimal at aortic valve repair
•Some data suggest that the use of a pericardial patch in aortic valve repair is associated with increased repair failure and this may be related to properties of the patch material

 

Study Aim

•This study sought to determine which commercially available pericardial patch would be best suited for aortic valve repair

 

Objective

•We compared three commercially available bovine pericardial patches, namely CardioCel® tissue-engineered patch, St-Jude MedicalTM Patch, and Periguard® Repair Patch, in order to determine the ideal pericardial patch for aortic valve repair

 

Conclusion: Among all three pericardial patches compared in this study, CardioCel®demonstrates the closest profile to that of the native aortic valve leaflet, rendering it best suited for aortic valve repair.
