Introduction: Primary aldosteronism (PA) is a common yet underdiagnosed cause of secondary hypertension, associated with increased cardiovascular and renal morbidity. Early detection and subtype-directed management significantly improve outcomes. However, adherence to recommended diagnostic pathways in real-world practice remains variable. Case: We conducted a retrospective audit of patients diagnosed with PA in a Malaysian tertiary centre from January 2018 to December 2025. Data collected included demographics, clinical presentation, biochemical parameters, diagnostic workup (aldosterone-renin ratio [ARR], confirmatory testing, adrenal imaging, and adrenal venous sampling [AVS]), treatment modality, and outcomes. Audit standards were based on established international guidelines. A total of 14 patients were included, with equal gender distribution. The cohort comprised 57% Malay and 43% Chinese. Most patients presented with hypertension (mean ~170/100 mmHg), and hypokalemia was present in approximately 70% of the patients. ARR and adrenal imaging were performed in all patients (100%), while confirmatory testing was conducted in 85% of the patients. However, AVS utilization remained limited (50%). Contributing factors included failed cannulation, technical challenges in overweight patients, preference for medical therapy, refusal of surgery, and limited access to AVS services. The majority had unilateral adrenal adenoma (~75%). Treatment was divided between surgical (55%) and medical (45%) approaches. Post-treatment, hypokalemia resolved in 90% of patients, with a significant reduction in antihypertensive burden and complete hypertension resolution in approximately 35% of the patients. Quality of life improved in most patients. Conclusion This audit demonstrates good adherence to initial screening and imaging in PA but highlights suboptimal utilization of AVS. Barriers to AVS utilization are multifactorial, encompassing technical, patient-related, and system level limitations. Addressing these barriers is essential to optimize subtype-directed management and improve longterm cardiovascular outcomes in patients with PA. Despite this, clinical outcomes were favorable. Strengthening adherence to diagnostic pathways, particularly subtype confirmation, may further improve patient outcomes.
