disclosure
Disclosure
  • Unfortunately none

Aortic Regurgitation
  • Causes
      • Biscuspid AV
      • Infective endocarditis
      • Senile degenerative disease
      • Collagen vascular disease
      • VSD
      • Subaorticstenosis
      • Aortic root dilatation
      • Aortic dissection
  • Must know if etiology is valvular or aortic disease
  • Often associated with MV abnormality also
pathophysiology
Pathophysiology
  • Acute
      • Abrupt increase in LVEDP with noncompliant LV and high EF and nL LV size
      • Dyspnea &/or pulmonary edema
  • Chronic
      • Excess volume stretches & elongates myocardial fibers which increases wall stress and causes hypertrophy
      • During exercise the volume of AI decreased b/c increased HR causes shortened diastolic period and decreased SVR
clinical syndrome
Clinical Syndrome
  • Dyspnea
  • Widened pulse pressure >100mmHg with DBP <60mmHg
  • Uncomfortable awareness of heart & neck vessels
  • Diastolic thrill at the base of the heart
  • High pitch diastolic, decresendo murmur best @ LSB
  • de Musset sign
  • Quincke sign
  • Marfan characteristics
  • IE stigmata
  • Corrigan pulse
  • Duroziez murmur
  • Austin Flint murmur
evaluation
Evaluation
  • ECG not necessarily unless LVH with chronic AI
  • CXR can hide may hide the proximal portion in the cardiac silhouette
  • TTE
  • TEE
  • MRI
  • Aortography
acute ai treatment
Acute AI Treatment
  • Surgery!

Dr. Brad Wolf- cardiothoracic surgery

chronic ai treatment
Chronic AI Treatment
  • Long standing overload causes progressive fibrosis and myocyte degeneration with subsequent LV dysfunction
  • Regular follow-up with echo q6- 12 months
  • Dental hygiene and IE prophylaxis
  • LV dysfunction usually develops before symptoms
  • Surgery
