BACKGROUND: The etiology of mitral valvular disease has changed in the last 20 years, and new techniques for the diagnosis and repair of mitral valves have been advanced. A retrospective regional study was conducted to identify changes in patient and disease characteristics and in population-based rates for mitral valve repair and replacement in northern New England. METHODS: Data from 1648 patients were collected from 5 clinical centers in Maine, New Hampshire, and Vermont between January 1, 1990, and December 31, 1999. U.S. Census data were used to calculate population-based rates. RESULTS: Total mitral valve procedures increased 2.4 times, from 8.7 to 20.6 cases/100,000/year (p(trend) = 0.004). Primary procedures increased from 6.7 to 16.9 cases/100,000/year (p(trend) = 0.014). Primary mitral valve repair procedures increased 3.7 times, from 2.4 to 8.9 cases/100,000/year (p(trend) = 0.012), whereas mitral valve replacement increased only 1.9 times, from 4.3 to 8.0 cases/100,000/year (p(trend) = 0.016). Repeat mitral valve operations did not change significantly (p(trend) = 0.810). During this period, there was a significant increase of the percentage of octogenarians (p(trend) = 0.016) and of patients with ejection fractions <40% (p(trend) = 0.012). There was a decrease in the percentage of patients with mitral stenosis (p(trend) = 0.024). CONCLUSION: In an era of a change in the etiology of mitral valvular disease and new techniques for diagnosis and repair of mitral valvular disease, regional data demonstrate substantial increased rates of mitral repair and replacement and expanded indications of older age and poorer left ventricular function. |
