Brief Summary:

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

Condition or disease Intervention/treatment Phase
Heart Valve Prosthesis Aortic Stenosis Hemodynamics Device: Sutureless aortic bioprosthesis Device: Conventional stented sutured aortic prosthesis Not Applicable

Detailed Description:

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

Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Comparison of Sutureless Vs. Standard Biological Prostheses for Surgical Aortic Valve Replacement: a Randomised Multicenter Study (Madrid, Spain)
Actual Study Start Date : June 2, 2019
Estimated Primary Completion Date : May 30, 2020
Estimated Study Completion Date : May 30, 2020

Arm Intervention/treatment
Experimental: Sutureless Aortic Valve Prosthesis
Patients receiving sutureless aortic valve prostheses
Device: Sutureless aortic bioprosthesis
Patients will receive a sutureless aortic bioprosthesis

Active Comparator: Conventional Aortic Valve Prosthesis
Patients receiving conventional biological aortic prostheses
Device: Conventional stented sutured aortic prosthesis
Patients will receive a stented sutured aortic prosthesis

Primary Outcome Measures :
  1. Differences in mid term trans prosthetic gradients [ Time Frame: 6 month ]
    The differences in mid term trans prosthetic gradients measured by trans thoracic echocardiogram 6 months after the procedure

Secondary Outcome Measures :
  1. Survival from Combined major adverse cardiovascular event [ Time Frame: 6 month ]
    Comparison of survival free from a combined event including: all cause mortality, major stroke (mRS>1), Myocardial Infarction (according to VARC-II criteria), Valve re operation of any case, major or life-threatening bleeding (VARC 2 definition)

  2. Differences in quality if life according to the KCCQ12 questionnaire [ Time Frame: 6 month ]
    Quality of life will be compared between the two groups using the Kansas City Cardiomyopathy Questionnaire (KCCQ12). The response options of the items are Likert scales of 1 to 5, 6 or 7 points and the score has a theoretical range of 0 to 100, with 100 being the best
