Coarctation of the Aorta Lesson #698
The patient was sitting leaning forward during auscultation.
Description
This lesson presents coarctation of the aorta, a congenital abnormality. S1 is normal, and the S2 sound is intensified. A diamond-shaped murmur spans most of systole while a high-pitched decrescendo murmur occurs in the first half of diastole.
In the cardiac anatomy video, observe a constriction in the descending aorta, which is responsible for the systolic murmur. There is regurgitant blood flowing from the aorta into the left ventricle producing the diastolic murmur. The left ventricle wall thickness is increased due to aortic pressure elevation caused by the aortic coarctation.

Coarctation of the Aorta
Play the cardiac movie and observe 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.
