Although mitral valve repair for mitral regurgitation is gaining in popularity, there are little comparative data with mitral valve replacement. Thus, Thourani and colleagues performed a case-controlled observational study of the Emory University Hospitals surgical database, matching 625 patients undergoing mitral valve repair with 625 undergoing mitral valve replacement from 1984 to 1997.

The Task Force on Valvular Regurgitation of the American Society of Echocardiography, in conjunction with the ACC, AHA, and ESC, has published recommendations for evaluating the severity of native valvular regurgitation by echocardiography. Unfortunately, the task force did not come up with a simple foolproof system.

Since patients with low gradient aortic stenosis are at higher risk for surgical replacement, more information concerning whom to select for surgery is desirable. Monin and colleagues from 6 centers in France studied 136 symptomatic patients with aortic valve area < 1.0 cm2, low cardiac index and a mean aortic pressure gradient < 40 mm Hg.
