Material and methods
All patients registered in the database who had valve replacement operations between 1986 and 1995, incorporating the 1996 harvest, were considered for inclusion in the study. Patient records that had obviously conflicting information or insufficient information were excluded from the study. The resultant population contained clinical information on 86,580 patients. The definition of each risk factor was consistent with the published guidelines in the STS National Cardiac Surgery Database
Patient characteristics
The patient populations grouped by subset model and the respective early mortality rates are given in Table 1. The total database encompassed 86,580 patients and the overall mortality was 7.5%. There were 26,317 patients with isolated aortic valve replacement (AVR) and 13,936 patients with isolated mitral valve replacement (MVR), with respective operative mortality rates of 4.3% and 6.4%. There were 3,840 patients with multiple valve replacement and the early or operative mortality rate was
Comment
The STS National Cardiac Surgery Database contains information from many institutions, both nonacademic and academic centers, on cardiac valve replacement operations in 86,580 patients during a 10-year period. The database provides a benchmark for quality assurance, because institutions can enter their patient population data and obtain direct risk-adjusted comparisons of their results with the national standard.
The patient population that had valve replacement operations has evolved during the
