Task: Question Answering
Input (English): Context: The authors reported a 73-year-old alcoholic man with previously-unrecognized situs inversus totalis suffering from left upper quadrant pain. Acute myocardial infarction was diagnosed and coronary angioplasty was performed immediately. However, the massive bleeding from the previously-unfound hepatomas caused hypovolemic shock and fatal outcome. Situs inversus totalis is a rare congenital anomaly with a complete mirror image of the thoracic and abdominal organs. Although being considered a benign entity, it would disturb diagnosis-making of the visceral diseases owing to the altered anatomy. To our knowledge, the coexistence of the coronary artery disease and ruptured hepatomas in situs inversus totalis, as in our patient, is never described. Recognition of any situs anomalies in time is the key to avoid misdiagnosis, inappropriate managements, and unwanted consequences. 
 Question: What is situs inversus?
Output (English): situs inversus totalis is a rare congenital anomaly with a complete mirror image of the thoracic and abdominal organs.
