Quantitative grading of mitral regurgitation, based on the effective regurgitant orifice of the valve and the regurgitated volume of blood, is a powerful predictor of the clinical outcome of medical management in asymptomatic patients. Patients with an effective regurgitant orifice of 40 mm2 or more should be considered for surgical repair.
The prognostic power of this quantitative classification superseded that of all other semiquantitative indexes, say the authors of the new study. They accurately determined the rates of death from any cause, death from cardiac causes, and cardiac events with the use of medical management based …
