Adrenal venous sampling (AVS) is regarded as the gold-standard for the study of lateralisation of primary aldosteronism (PA) after its biochemical diagnosis. After catheterisation of both adrenal veins, confirmed by ratio of cortisol concentration in each adrenal vein and peripheral vein (selectivity index (SI)), lateralization is accepted if aldosterone/cortisol (A/C) ratio between both adrenal veins is over 3–4 (lateralization index (LI)), particularly if non-dominant v...
