SUSTAINED MEAN AORTIC PRESSURE GRADIENT REDUCTION THREE YEARS AFTER TRANSCATHETER AORTIC VALVE REPLACEMENTS: RESULTS FROM THE MARSHFIELD AORTIC VALVE EXPERIENCE PILOT SUBSTUDY

Although prior studies showed mean aortic valve pressure gradient (mAoVpg) dramatically drops in patients with severe aortic stenosis following Transcatheter Aortic Valve Replacement (TAVR) with different valve types; it is not well known if this drop in mAoVpg is sustained through the years after
