Primary aldosteronism: making sense of partial data sets from failed adrenal venous sampling-suppression of adrenal aldosterone production can be used in clinical decision making

The cortisol-corrected adrenal vein/inferior vena cava aldosterone index with a cutoff value of ≤0.5 performed well in identifying patients with contralateral unilateral disease. AV/IVC index of ≥5.5 cannot be used to reliably diagnose ipsilateral unilateral disease because 18% of patients undergoing adrenalectomy based on this cutoff would have bilateral disease.
