The convergence zone method is currently used routinely to quantify valvular regurgitation, particularly mitral insufficiency, but also aortic and tricuspid regurgitation. It is quick to perform, requires relatively little training and remains valid in the presence of atrial fibrillation and in the association of regurgitation-stenosis. It relies on the measurement of output at the level of an isovelocity hemisphere and allows calculation of the regurgitant orifice surface (SOR) and the regurgitant volume per beat (VR). It is reserved for severe regurgitation corresponding to angiographic grade 4: SOR > 40 mm2 and VR > 60 ml for mitral insufficiency, SOR > 30 mm2 and VR > 60 ml for aortic insufficiency, and SOR > 40 mm2 and VR > 40 ml for tricuspid insufficiency.
