Primary aldosteronism PA is a common cause of secondary hypertension, and its diagnosis and treatment pose significant challenges. This research investigates adrenal venous sampling AVS, which is considered the best method to distinguish between different types of PA. The study aims to address clinical, technical, and methodological questions about AVS and to understand how AVS-guided management influences long-term health and biochemical results to improve patient care. Participants with PA will undergo adrenal venous sampling through either the antecubital or femoral vein to identify whether aldosterone overproduction is unilateral or bilateral. This observational study evaluates the AVS procedure itself and its clinical outcomes, refining protocols and standardizing practices to optimize treatment decisions and patient prognosis. Throughout the study, researchers will monitor major cardiovascular events one year after AVS. They will also assess procedure success rates, complications, medication changes, blood pressure, heart and kidney function, and clinical outcomes over multiple years. The follow-up includes assessments at 1, 3, 6, 12, 18 months, and up to 10 years, enabling comprehensive evaluation of long-term effects and safety.
