Impact of Patient-Prosthesis-Mismatch on Coronary Flow Reserve
NCT00310947 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 48
Last updated 2006-04-05
Summary
Complete normalization of CFR following AVR for aortic stenosis was observed only for stentless valves. Besides the superior hemodynamic performance this might explain the excellent long term results of this valve design.
