1 Serial Changes of Hemodynamic Performance With Medtronic Hall Valve in Aortic Position 
Yang Hyun Cho, MD, Dong Seop Jeong, MD, PhD, Pyo Won Park, MD, PhD, Kay-Hyun Park, MD, PhD, Kiick Sung, MD, PhD, Wook Sung Kim, MD, PhD, Young Tak Lee, MD, PhD  The Annals of Thoracic Surgery  Volume 91, Issue 2, Pages (February 2011) DOI: /j.athoracsur Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Histogram showing the frequency distribution of change in transprosthetic mean pressure gradient (ΔTMPG) increases during 5 years. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Serial changes in transprosthetic mean pressure gradient (TMPG) during follow-up for aortic valve replacement versus double valve replacement (A) and for 20-mm versus greater than 20-mm Medtronic Hall (MH) valves (B).

5 Fig 4 Kaplan-Meier survival curves and valve-related event-free survival curves. No significant survival difference was observed between the aortic valve replacement (AVR) and double valve replacement (DVR) groups (A). The survival of patients with a 20-mm Medtronic Hall (MH) valve in the aortic position was not significantly lower than that of patients with a larger valve (B). Valve-related event-free survival was significantly greater for patients who underwent aortic valve replacement than for those who underwent double valve replacement (C). Valve-related event-free survival was significantly lower for patients with a 20-mm Medtronic Hall valve than for those with a larger Medtronic Hall valve (D).
