Autonomic dysfunction and aortic stenosis can cause syncope. Patients with aortic stenosis experiencing syncope may also have autonomic dysfunction, a combination that requires careful consideration for effective treatment.

Area of Science:

  • Cardiology
  • Neurology

Background:

  • Autonomic dysfunction and aortic stenosis share symptoms like syncope.
  • Both conditions often manifest later in life and are idiopathic.

Observation:

  • Three of 36 patients referred for autonomic dysfunction had a history of aortic valve replacement for stenosis.
  • Presenting symptoms of fatigue, light-headedness, and syncope were initially attributed solely to aortic stenosis.

Findings:

  • Concomitant autonomic dysfunction may significantly contribute to symptoms in patients with aortic stenosis unresponsive to surgery.
  • The combination of aortic stenosis and autonomic dysfunction presents a dangerous interplay affecting cardiac output and venous return.

Implications:

  • Consider autonomic dysfunction in aortic stenosis patients with syncope to address dual pathophysiologies.
