This is an example of coarctation of the aorta, a congenital abnormality.This first heart sound is normal. The second heart sound is intensified.There is diamond shaped murmur occupying most of systole and a high-pitched decrescendo murmur in the first half of diastole.In the anatomy tab you can see a constriction in the descending aorta which is responsible for the systolic murmur.There is regurgitant flow from the aorta into the left ventricle which causes the diastolic murmur.The left ventricle wall thickness is increased due to aortic pressure elevation caused by the aortic coarctation. The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis. Listening Tips A summary of the key aspects of this heart or lung sound. Systole: Diamond-shaped murmur, possible early systolic ejection sounds.S2: Increased intensity. Diastole: High pitched, decrescendo, early murmur. Auscultation Method The recommended patient position is sitting leaning forward For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is aortic Relevant Courses If you wish to review a complete mobile concerning Coarctation of the Aorta Auscultation Reference and related heart sounds, the modules(s) listed below may be useful. Each lesson includes text that explains the auscultatory sound and its clinical significance. The lesson also includes an audio track for playback. A waveform provides a great way to visualize the sounds. Finally, we also include an animation video. For heart sounds, the video illustrates heart muscle and valve movements along with blood flow. For lung sounds, the primary source of the sounds can be seen. Each module also includes a quiz.
