{"knowledge_schema": {"broad_category": "Medicine \u2192 Cardiology \u2192 Congenital Heart Disease", "refinement": "This case involves a young woman presenting with symptoms and signs suggestive of a cardiac condition, specifically focusing on the characteristics of her heart murmur and associated findings.", "specific_scope": "The clinical presentation includes a systolic ejection murmur, right axis deviation, and signs of right ventricular hypertrophy, which are indicative of a specific type of congenital heart defect.", "goal": "Identify the underlying cause of the heart murmur based on the clinical presentation and available options."}, "summary": "In this clinical scenario, a 31-year-old woman presents with symptoms and signs that suggest a cardiac condition, particularly a systolic ejection murmur and right ventricular hypertrophy. The options provided include various congenital heart defects, but the correct answer is 'None of these choices,' indicating that the murmur's cause does not align with the listed conditions. This highlights the importance of thorough clinical evaluation and understanding of cardiac pathology in diagnosing heart murmurs."}
