Objective: Adrenal venous sampling (AVS) is the gold standard method to assess lateralization of aldosterone secretion in patients with primary aldosteronism (PA). The selectivity index (SIcortisol, the adrenal to peripheral vein ratio of cortisol concentrations) determines correct catheter positioning during AVS. The lateralization index (LIcortisol, the aldosterone to cortisol ratios between adrenal veins) distinguishes unilateral aldosterone producing ...
