Spontaneous Regression of Possible Transcatheter Aortic Valve Thrombosis Without Additional Anticoagulant: Two-Year Follow-Up.

Spontaneous Regression of Possible Transcatheter Aortic Valve Thrombosis Without Additional Anticoagulant: Two-Year Follow-Up. J Invasive Cardiol. 2017 May;29(5):E64 Authors: Yanagisawa R, Hayashida K, Jinzaki M, Fukuda K Abstract An 84-year-old man with symptomatic severe aortic stenosis received transcatheter aortic valve implantation (TAVI). Dual-antiplatelet therapy was continued for 6 months post TAVI, and aspirin alone was used thereafter. Four-dimensional multidetector computed tomography revealed a new hypoattenuated leaflet thickening (HALT) with reduced leaflet motion at 1 year, considered to indicate leaflet thrombosis. At the 2-year follow-up, leaflet mobility had improved, with spontaneous regression of HALT. This is the first report of confirmed spontaneous regression of possible transcatheter heart valve thrombosis and recovery of leaflet mobility without the need for additional anticoagulant.
