This is a simulation of Aortic Stenosis - Moderate and Regurgitation - Mild taken at the second right intercostal space.  S1 is normal.  S2A is single and accentuated.  An aortic ejection click is heard. A diamond-shaped systolic murmur is present. A mild, high-pitched, blowing, decrescendo diastolic murmur is present.  The EKG shows an increased R-wave amplitude, which is evidence of LVH. 
Look at the cardiac animation. It shows left ventricular hypertrophy and a thickened, mobile aortic valve.  Note the Doppler-plumes, which represent systolic turbulent flow across a stenotic aortic valve and diastolic regurgitant turbulent flow into the left ventricle.
