- 1. In assessing the severity of aortic stenosis:
- The pressure gradient across the valve is the most accurate method.
- Angiography is not always required.
- Exercise tolerance is a good measure of severity.
- The pressure gradient measured at angiography will be higher than that found on the echocardiogram.
- The pressure gradient severity tends to be over estimated in pregnancy.
- 2. Important factors in the intraoperative care of the patient with aortic stenosis include:
- Avoiding hypotension.
- Maintaining systemic vascular resistance.
- Avoiding tachycardias.
- Never using regional anaesthesia.
- Avoiding intubation.
- 3. When considering the aetiology of aortic stenosis:
- Aortic sclerosis is a benign variant.
- Stenosis is common without calcification.
- Bicuspid valves are more common in younger patients.
- Rheumatic disease is a common cause of isolated aortic stenosis.
- Bicuspid valves are best seen on echo in diastole.
- 4. The continuity equation:
- Contains the cross-sectional
