To assess if the non use of heparin sodium during balloon aortic valvuloplasty reduces serious complications due to the procedure, by decreasing the rate of vascular and hemorrhagic complications without increasing the rate of ischeamic events.

Condition Intervention Phase
Aortic Stenosis, Non-rheumatic
Drug: Heparin
Drug: NaCl
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study

Further study details as provided by University Hospital, Montpellier:

Primary Outcome Measures:
  • Number of serious complication : vascular, hemorrhagic or ischaemic complication [ Time Frame: Up to10 days after the valvuloplasty (D1-D10 after the intervention) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of any non serious complication directly associated with the procedure (vascular, hemorrhagic or ischaemic complication) [ Time Frame: up to30 days after the valvuloplasty (until D30 after intervention) ] [ Designated as safety issue: No ]
    Non serious complication is complication directly associated with the valvuloplasty which could be vascular complications medically treated (compression), BARC 2 hemorrhage, general procedure complications

  • number of a serious complication : vascular, hemorrhagic or ischaemic complication [ Time Frame: up to 30 days after valvuloplasty ] [ Designated as safety issue: No ]
