(b) Angiography is required only to assess the coronary arteries. (c) Patients with severe aortic stenosis can be asymptomatic. (d) Echocardiography measures the maximum pressure difference, which is higher than the peak-to-peak gradient that can be measured at the same time as angiography.
2. Important factors in the intraoperative care of the patient with aortic stenosis include:
(a) True; (b) True; (c) True; (d) False; (e) False
(a–c) The important factors are avoiding hypotension, reduced systemic vascular resistance and tachycardia as these all predispose to myocardial ischaemia. (d,e) The anaesthetic technique itself is unimportant as long as the above principles are adhered to.
