PAINE #PANCE Pearl – Cardiovascular



82-year-old male, with a history of HTN, HLD, and CAD, presents to your clinic with a six-month history of dyspnea on exertion.  He states he is unable to walk as far as he used when exercising, and when he over exerts himself, he reports having some mild chest pain and feeling lightheaded.  This resolves with rest and he denies any syncope with these events.

EKG


 

This patient has aortic stenosis.  The suggestive parts of the H&P are:


  1. What is the next step in the management of this patient?
    1. Transthoracic echocardiography
  2. After the next step, what important variables must you specifically assess?
    1. Valvular anatomy and size
      1. Aortic valve surface area
    2. Valve hemodynamics
      1. Transvavular aortic velocity
      2. Mean transvalvular pressure
    3. LV size and ejection fraction
    4. Pulmonary artery pressure
    5. Other concomitant conditions

 

These variables will help with staging the severity of the stenosis, as well as determine need for operative intervention.
