3 Fig 2 Overall survival after correction of severe aortic valve regurgitation stratified by preoperative left ventricular ejection fraction greater than or less than 60%.

4 Fig 3 Mean left ventricular ejection fraction (EF) before (Pre) and after correction of aortic valve regurgitation. Pink bars indicate the EF at each postoperative time point. Blue bars indicate the preoperative EF for the same patients whose postoperative EF data is available at that time point for purpose of paired comparison. ∗Statistically significant change in EF in the paired data.
