Bicuspid aortic stenosis laboratory tests

Introduction

Overview

Overview

Laboratory tests such as lipid profile, BNP levels and blood studies help in assessing the progress and outcomes of bicuspid aortic stenosis.

Laboratory Tests

Laboratory Tests

  • As hypercholesterolemia is one of the risk factors that accelerates the stenotic process via calcification, serum cholesterol levels should be tested which could aid in recommending dietary modifications or medications.
  • Brain natriuretic peptide (BNP) may aid in assessing the cardiac function of patients with asymptomatic severe bicuspid aortic stenosis.[2]. Rising levels of BNP predicts the need for valve surgery in patients with asymptomatic severe aortic stenosis. It may also provide important prognostic information on postoperative outcomes.[3]
  • Complete blood count with peripheral smear may reveal hemolytic anemia with schistocytes secondary to mechanical trauma to RBCs from calcified bicuspid valves.
