Аудіо 00052. Artificial stenosis of the pulmonary artery (banding)

Example of a fifth-degree systolic murmur. This child has a complicated heart defect that cannot be corrected at one time but requires several palliative operations. Pulmonary circulation pressure was elevated earlier, and to prevent irreversible pulmonary vascular damage an artificial stenosis (banding) of the pulmonary artery was performed. In the phonogram the murmur is louder than S1 and S2 and the configuration is diamond-shaped. Tight stenosis is also the cause of the high frequency murmur that extends to over 1000 Hz. Age 0.4 years. Area of auscultation: left second ic (LIC2).
