University Hospital, Angers
  Purpose
RIP-VALVE is a randomized, single blinded study that will test the hypothesis that remote ischemic preconditioning initiated before surgery reduces post-operative myocardial damage in aortic valve surgery. Infarct size will be determined by 72 hours area under curve of troponin-I.

Condition Intervention
Aortic Valve Stenosis Procedure: Control Procedure: Remote ischemic preconditioning

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Remote Ischemic Preconditioning in Aortic Valve Surgery (RIP-Valve)

Primary Outcome Measures:
  • Infarct size [ Time Frame: 72 hours ]
    Infarct size as assessed by 72 hours area under curve serum troponin-I


Enrollment: 100
Study Start Date: July 2011
Study Completion Date: October 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Control Procedure: Control
Deflated blood pressure cuff placed on upper arm for 30min
Active Comparator: Remote ischemic preconditioning Procedure: Remote ischemic preconditioning
Blood pressure cuff placed on upper arm and inflated to 200 mmHg for 5 min and then deflated for 5 min. This cycle is initiated before aortic clamping and repeated 3 times in total

Detailed Description:
The hypothesis tested in this research proposal is that remote ischemic preconditioning initiated immediately before aortic valve surgery reduces myocardial damage related to surgery.
