Background: Subtyping of primary aldosteronism (PA) using imaging and adrenal vein sampling (AVS) can yield discordant results. Varying interpretation criteria in determining AVS lateralization may affect discordance rates.Methods: We identified 337 consecutive patients with PA who underwent AVS at a quaternary care centre between August 2006 and February 2018. Patient demographics, laboratory results, diagnostic imaging, AVS results, and pathology were ...

Background: Negative imaging in the work-up for unilateral (surgical) primary aldosteronism (PA) presents a diagnostic dilemma. Clinicians may assume bilateral disease and treat medically or may proceed to adrenal vein sampling (AVS) to try to localize a unilateral source of aldosterone secretion. However, AVS is not without cost, risk, and limited access. We describe AVS results among imaging-negative PA patients.Methods: We identified 96 patients with ...
