Mechanical heart valves: are two leaflets better than one? YingXing Wu, MD, Rosario Gregorio, MD, Attilio Renzulli, MD, FECTS, Francesco Onorati, MD, Marisa De Feo, MD, Gary Grunkemeier, PhD, Maurizio Cotrufo, MD, FECTS The Journal of Thoracic and Cardiovascular Surgery Volume 127, Issue 4, Pages 1171-1179 (April 2004) DOI: 10.1016/j.jtcvs.2003.08.030

Figure 1 The use of L1 and L2 valves over time. The shaded area indicates the time period when the use of the 2 valve types overlapped. The Journal of Thoracic and Cardiovascular Surgery 2004 127, 1171-1179DOI: (10.1016/j.jtcvs.2003.08.030)

Figure 2 Actuarial overall survival after valve replacement for patients operated on from 1987 through 1995 (shaded area in Figure 1). Numbers above the horizontal axis indicate the number of patients at risk. The Journal of Thoracic and Cardiovascular Surgery 2004 127, 1171-1179DOI: (10.1016/j.jtcvs.2003.08.030)

Figure 3 Freedom from explantation after valve replacement for patients operated on from 1987 through 1995 (shaded area in Figure 1). Numbers above the horizontal axis indicate the number of patients at risk. The Journal of Thoracic and Cardiovascular Surgery 2004 127, 1171-1179DOI: (10.1016/j.jtcvs.2003.08.030)

Figure 4 Thromboembolism rates for L1 and L2 valves (all time frames). Circles indicate L1 valves, and paired semicircles indicate L2 valves. Dashed horizontal lines indicate weighted mean rates for each valve group. Two-letter valve-model abbreviations are specified in Table 1. Numbers at the bottom of the graph show the number of events (Events) and total late follow-up years (Pt-yrs) for each valve model. For statistical comparisons between L1 and L2 valves during the concurrent era only, see Table 6. For model abbreviations, see Table 1.
