Laboratory studies for AR may also include the following:

  • Complete blood count (CBC)

  • Prothrombin time (PT)/activated partial thromboplastin time (aPTT)

  • Type and screen

  • Electrolytes

  • VDRL

  • Lactate dehydrogenase

Early surgical intervention is recommended in cases of AR caused by infective endocarditis, and emergent intervention is warranted in cases caused by aortic dissection.
