Introduction: This article summarizes the clinical practice guide (CPG) for the evaluation and management of patients with severe aortic stenosis in the Social Security of Peru (EsSalud). Objective: To provide clinical evidence-based recommendations for the evaluation and management of patients with severe aortic stenosis in the EsSalud. Methods: A local guideline development group (local GDG) was established, including medical specialists and methodologists. The local GDG formulated 7 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and, when it was considered pertinent, primary studies, were conducted in PubMed during 2018. The evidence to answer each of the posed clinical questions was selected. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the local GDG used the GRADE methodology to review the evidence and formulate the recommendations, points of good clinical practice, and the flowchart of evaluation and management. Finally, the CPG was approved with Resolution N.° 47 – IETSI – ESSALUD – 2018. Results: This CPG addressed 7 clinical questions regarding two issues: the initial evaluation and the management of severe aortic stenosis. Based on these questions, 9 recommendations (1 strong recommendation and 8 weak recommendations), 16 points of good clinical practice, and 1 flowchart were formulated. Conclusion: This article summarizes the methodology and evidence-based conclusions from the CPG for the evaluation and management of patients with severe aortic stenosis in the EsSalud.
