Key result
Von Willebrand factor multimer profile analysis evaluates heart valve disease severity, predicts clinical events, and serves as an accurate marker of surgical and transcatheter intervention quality.
Why the study?
Despite an established relationship between VWF multimer profiles and heart valve diseases, an evidence-based framework is needed to guide its clinical implementation and define research priorities.

“The close relation of these VWF defects with blood flow abnormalities and their correction after aortic valve replacement is now well established, and in AS VWF, it has been proposed to monitor transcatheter aortic valve implantation procedures.”
“When Edward Heyde, a general practitioner, described the syndrome of gastrointestinal bleeding in the presence of aortic stenosis that bears his name, there is no way he could have known that his observations would open doors for a procedure that was completely inconceivable at the time of his writing.”
May support VWF multimer profiling to refine heart valve disease risk assessment; leaves open prospective validation before clinical adoption.
For decades, numerous observations have shown an intimate relationship between von Willebrand factor (VWF) multimer profile and heart valve diseases (HVD). The current knowledge of the unique biophysical properties of VWF helps us to understand the longstanding observations concerning the bleeding complications in patients with severe HVD. Not only does the analysis of the VWF multimer profile provide an excellent evaluation of HVD severity, it is also a strong predictor of clinical events. Also of importance, VWF responds within minutes to any significant change in hemodynamic valve status, making it an accurate marker of the quality of surgical and transcatheter therapeutic interventions. The authors provide in this review a practical, comprehensive, and evidence-based framework of the concept of VWF as a biomarker in HVD, advocating for its implementation into the clinical decision-making process besides usual clinical and imaging evaluation. They also delineate critical knowledge gaps and research priorities to definitely validate this concept.

Belle et al. (2019) conducted a review in Heart valve disease. von Willebrand factor (VWF) multimer profile was evaluated. Von Willebrand factor multimer profile analysis evaluates heart valve disease severity, predicts clinical events, and serves as an accurate marker of surgical and transcatheter intervention quality.
