Leaflet Hypomobility After Transcatheter Aortic Valve Replacement: Thrombosis or Mechanical Factors? A Possible Pathophysiological Pattern.

Transcatheter heart valve replacement is an emerging technology in the treatment of valvular disease. During recent years, the opportunity to replace a heart valve via percutaneous access or via a miniinvasive access without the use of cardiopulmonary bypass has revolutionized the approach to this pathology. The different designs of transcatheter valves have also altered the spectrum of possible complications, with the unexpected occurrence of leaflet hypomobility after valve deployment. Here, the pathophysiological pattern of this complication is categorized, and an analysis provided of recently reported clinical evidences.
