                35.  What are the clinical features of aortic stenosis?
              Table 7: Clinical features of aortic stenosis
              History         •   Angina chest pain, exertional syncope, dyspnea
                              •   Slow rising pulse with reduced amplitude and
              Pulse            sustained contour, with or without carotid thrill
                               (anacrotic or pulsus parvus et tardus)
              Precordial      •   Usually undisplaced and heaving apical
              impulses         impulse
                              •   S1 is normal
                              •   Absent S2 or soft S2 with paradoxical splitting
                              •   S4 and S3 in late stages with left ventricular
              Heart sounds     dysfunction
                              •   Ejection click (high-pitched systolic sound
                               which helps to localize the pathology to the
                               valvular level; best heard at the cardiac apex)
                              •   High-pitched, harsh or rasping, late peaking,
                               mid-systolic murmur in the aortic area,
                               radiating to the carotids. The murmur is
              Murmur
                               preceded by ejection click
                              •   Presence of Gallavardin effect (especially in
                               elderly)












              Note: The murmur of aortic stenosis is best heard with the diaphragm
              of the stethoscope in the sitting up and leaning forward position, with
              the breath held in expiration
