1 Mitral Valve Repair for Degenerative Disease: A 20-Year Experience
Mani A. Daneshmand, MD, Carmelo A. Milano, MD, J. Scott Rankin, MD, Emily F. Honeycutt, MBI, Madhav Swaminathan, MD, Linda K. Shaw, MS, Peter K. Smith, MD, Donald D. Glower, MD  The Annals of Thoracic Surgery  Volume 88, Issue 6, Pages (December 2009) DOI: /j.athoracsur Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Frequency per year of mitral valve repair versus mitral replacement for degenerative disease at Duke University from 1986 through 2006. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 (A) Unadjusted Kaplan-Meier survival curves. (B) Survival curves for groups 1 and 2, after Cox model statistical adjustment for differences in baseline characteristics.

4 Fig 3 Unadjusted Kaplan-Meier survival curves for patients older than and younger than 65 years of age, stratified by valve repair versus replacement. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2009 The Society of Thoracic Surgeons Terms and Conditions

5 Fig 4 Unadjusted (A) and adjusted (B) survival curves for repair versus mechanical valve replacement versus tissue valve replacement. No statistical comparison was performed because of concerns about the small sample size of tissue valves, but the trend is apparent.

6 Fig 5 Observed survival of propensity-matched quintiles during 15 years of follow-up. Quintile 5 has the greatest propensity for replacement (red), and 1 has the greatest propensity for repair (green). Late survival was better with repair in all quintiles (p = 0.046).
