GirardiMONDAYAfternoonOBJECTIVE: An increasing number of patients with previous sternotomy requireaortic valve replacement (AVR). We compared the outcomes of reoperative AVRafter previous sternotomy with primary AVR over time. Further, the effect of primaryoperation on reoperative AVR was investigated.METHODS: Between January 1996 and December 2007, 1603 patients undergoingelective AVR were entered prospectively into our clinical database. Patients weredivided into three eras: I: 1996–1999, II: 2000–2003, III: 2004–2000. A total of 191patients (12% [191/1603]) had previous sternotomy for CABG (n = 88), CABG withAVR (n = 16), AVR with or without other aortic procedure (n = 30) and other cardiacprocedures (n = 17). The mean age was 66.5 ± 13.1 years in reoperative AVR patientsand 65.5 ± 12.0 years in primary AVR patients.Outcome 1996–1999 2000–2003 2004–2007 P-valuePrimary AVR (n = 1412) 316 (22%) 554 (39%) 542 (38%)
