“…Published and unpublished data confirm that outlet structure fractures have occurred often with fatal outcomes in 633 (0.7%) of the 86,000 Björk-Shiley convexoconcave prosthetic heart valves implanted (35). Fractures continue to occur at a rate of 0.1% per year, so that risk of valve replacement now typically exceeds risk of sudden death associated with valve failure.…”

A comprehensive review of articles on cardiovascular surgery in major general and cardiovascular journals published in 2005 identified a large number that were scientifically sound and broadly relevant. The scientific quality of the 43 articles chosen as most likely to affect the future practice of cardiovascular specialists made it difficult to identify a single work as the "outstanding cardiovascular surgical article of 2005." However, the "most valuable topic award" clearly goes to four articles that distill down and validate multivariable model information into bedside risk prediction tools that quantitate:• The natural history of patients with prior coronary artery bypass grafting (CABG) using coronary angiography. • Operative mortality and five-year survival in patients with low ejection fraction (EF) using five clinical variables. • Major infection after CABG using preoperative variables with or without intraoperative variables. • Operative risk for aortic and mitral valve surgery using clinical information.Careful use of these scores to adjust estimates for differences in outcomes in care environments that develop (and care providers who apply) the predictive tool will infuse quantitative thinking into physician deliberation and provide patients with information describing personalized risks and benefits to inform their deliberations about an operation.

“…The BSCC disc was constrained within the device by inlet and outlet struts. The inlet strut was integral with the prosthesis flange, but the outlet strut was welded to it (see Figure 1 in the original article 1 ). There were a limited number of flange sizes; the 31-and 33-mm label sizes used 29-mm flanges.…”

“…The court correctly recognized that reoperations should be confined to patients at greatest risk of OSF. 1 Medical decision making is impeded by the lack of an accurate test predictive of future OSF and the lack of patient-level, detailed clinical data that together may more accurately identify those most vulnerable to OSF. Even if better models were available than that presented in Table 6 1 , how should they be used?…”

“…The BScc valve was implanted from 1979 onward and voluntarily removed from the market by Shiley Laboratories in 1986 (Camp et al 1997;Omar et al 2001b). By that time an estimated 86,000 BScc valves were implanted worldwide (van Gorp 2003), with approximately 22,000 recipients still alive by 2005 (Blot et al 2005).…”

“…However, the underreporting of OSF events is estimated to be approximately 10% to 25 %, as the symptoms of a death caused by OSF of an aortic BScc valve are similar to those of arrhythmogenic death (Kallewaard et al 1998;Omar et al 2001a;Omar et al 2001b;Blot et al 2005).…”
