Aortic stenosis is the narrowing of the outflow tract of the left ventricle due to calcification of the aortic valve.
Anesthetic implications
Preoperative optimization
Asymptomatic aortic stenosis may be initially detected on physical exam. Peripheral pulses may be weak and late (sometimes called pulsus parvus et tardus). A loud systolic crescendo-decrescendo murmur may also be present, which is best heard at the right upper sternal border at the 2nd intercostal space. This murmur may also radiate to the carotid arteries.
Patients with suspected aortic stenosis should undergo Transthoracic echocardiogram to confirm the diagnosis and evaluate the severity of the disease. For severe disease, valve replacement therapy should be considered prior to proceeding with elective surgery.
