This symptomless girl in good condition has a haemodynamically insignificant pulmonary stenosis. On echocardiography the flow gradient is 17-22 mmHg. On auscultation a second-degree coarse, low frequency pansystolic murmur is heard. Phonogram shows the diamond shape that matches stenosis murmur. In spectrogram he maximum frequencies are in the range of 400 Hz. Flow velocity is highest in the beginning of systole, and the highest frequencies also occur in early systole and the frequency contour is descending. The findings resemble ASD the main difference being that P2 is quieter than normal. Because the stenosis is mild, P2 can, however, be heard. Age 9.5 years. Area of auscultation: left second ic (LIC2).
