Balloon Aortic Valvuloplasty Performed Without Heparin to Decrease Vascular and Bleeding Complications of the Procedure (HEPAVALV)

June 10, 2026 updated by: University Hospital, Montpellier
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.
