Aortic Stenosis. The aortic stenosis murmur is diamond-shaped and systolic and radiates along the aortic outflow tract. The peaking of the murmur moves toward S2 as the valve area narrows. Classically, the aortic stenosis murmur is heard best at the right upper sternal border (where it is harsh and noisy).diopathic Hypertrophic Subaortic Stenosis. Subaortic stenosis is a harsh, diamond-shaped, mid-systolic murmur heard best at the left sternal border. Maneuvers that change the murmur include the fact that it becomes louder during a PVC, softer on the beat following PVC, softer with squatting, and louder with standing.
