1 Right anterior minithoracotomy for aortic valve replacement: 10-year experience of a single center 
Mattia Glauber, MD, Daniyar Gilmanov, MD, Pier Andrea Farneti, MD, Enkel Kallushi, MD, Antonio Miceli, MD, Francesca Chiaramonti, MD, Michele Murzi, MD, Marco Solinas, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 150, Issue 3, Pages e2 (September 2015) DOI: /j.jtcvs Copyright © 2015 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Proportion of aortic valve replacement cases performed via RAMT over time, year by year (numbers above the bars indicate % of the total number of isolated aortic valve replacement operations). Sternotomy approach (green bar) includes both full and partial sternotomy. Cases involving RAMT (blue bar) indicate that since 2011, the overall number of AVR cases has increased, owing to the RAMT component. RAMT, Right anterior minithoracotomy.

4 Figure 3 Comparison of survival by Kaplan-Meier between sutured and sutureless cohort. Green line and green numbers refer to sutureless prostheses; blue line and blue numbers refer to sutured prostheses. Shorter follow-up in the sutureless group, with information lacking over 24 months, is evident by “block” shape of green line.

5 Figure 4 Follow-up survival by Cox multivariable proportional hazards regression model at mean of covariates, stratified by the type of aortic valve prosthesis (hazard ratio 1.02; 95% CI: ; P = .97). Shorter follow-up in the sutureless group, with information lacking over 24 months, is evident by “block” shape of green line.
