May signal higher perioperative bleeding risk in valvular disease; hypothesis-generating for platelet testing before valve surgery.
Do patients with valvular heart disease have greater high-shear platelet dysfunction compared to patients with coronary artery disease?
Patients with aortic or mitral valve disease exhibit significantly more frequent high-shear platelet dysfunction compared to those with coronary artery disease, which may increase the risk of intra-operative bleeding.
