Three cases with the perforated aortic valve by infective endocarditis were examined by two-dimensional echocardiography and color flow mapping. In all the cases, the correct diagnosis of aortic valve perforation was difficult by two-dimensional echocardiography alone. However, recognition of the regurgitation signal from both the coaptation zone and perforative cusp by color flow mapping led to diagnosis of aortic valve perforation. In conclusion, color flow mapping combined with two-dimensional echocardiography is useful in the detection of aortic valve perforation.
