Aortic Stenosis Clinical Trial
Official title:
Comparison of Sutureless Vs. Standard Biological Prostheses for Surgical Aortic Valve Replacement: a Randomised Multicenter Study (Madrid, Spain)
Multicenter randomised study which aims to compare sutureless Vs. standard bio- prostheses
(1:1) among patients undergoing surgical aortic valve replacement in terms of:
- 6 -month hemodynamic performance.
- 6 month clinical outcomes including all cause mortality, stroke, myocardial infarction,
valve reoperation and major/life threatening bleeding
- Cost effectiveness
This study is aimed to compare clinical and hemodynamic performance of conventional sutured
stented bio-prostheses among patients undergoing a surgical aortic valve replacement. The
prostheses are not pre specified to be provided by a specific manufacturer, so that any bio
prosthesis but transcatheter and scentless aortic valves can be implanted.
The estimated sample size is 350 patients. They will be randomised 1:1 to any of the two arms
of the study (standard Vs. sutureless prostheses). The randomisation will be stratified
according to the need for a concomitant coronary artery bypass grafting procedure.
Six hospitals in Madrid (Spain) will take part in the study. The period of recruitment will
start as soon as June 2019 and is supposed to finish by June 2020 or earlier.
The main outcomes of the study will be measured 6 months after the aortic valve implantation
