Fig 1 Kaplan-Meier curves showing freedom from reoperation for valve explant during the first 2 years postoperatively (Postop). The Annals of Thoracic Surgery 2002 73, 785-792DOI: (10.1016/S0003-4975(01)03442-7)
Fig 2 Kaplan-Meier curves showing freedom from major paravalvular leak for patients having aortic valve replacement (A) and mitral valve replacement (B). (Postop = postoperative.) The Annals of Thoracic Surgery 2002 73, 785-792DOI: (10.1016/S0003-4975(01)03442-7)
Fig 3 Kaplan-Meier curves showing freedom from thromboembolism during the first 2 years postoperatively (Postop). The Annals of Thoracic Surgery 2002 73, 785-792DOI: (10.1016/S0003-4975(01)03442-7)
Fig 4 Linearized rates of thromboembolism (A) and stroke (B). Risks of thromboembolism were higher for patients in the Silzone group compared with the non-Silzone valve, but these differences were largely due to transient events because the risks of stroke were low.

Fig 5 Analysis of cumulative hazard of major paravalvular leak suggests a constant risk of 4.6% during the first 2 years after the operation. (CI = confidence interval; Postop = postoperative.) The Annals of Thoracic Surgery 2002 73, 785-792DOI: (10.1016/S0003-4975(01)03442-7)
