Referred for investigation of a murmur. ECG, chest radiograph and BP are normal. This second-degree murmur sounds and appears on the phono- and spectrograms as a physiological ejection sound. The murmur was best heard in the right second ic and left third ic, i.e. the aortic area. Echocardiography showed a bicuspid normally opening aortic valve. The flow of the ascending aorta was normal, laminar. This finding has no haemodynamic significance; however, even mild aortic valve anomalies may involve the risk of endocarditis. All physiological sounds heard clearly in the aortic area should therefore be checked with echocardiography. Age 9.7 years. Area of auscultation: left third ic (LIC3).
