Atypical Presentation of Acute Mitral Regurgitation Secondary to Papillary Muscle Rupture.

Acute mitral regurgitation (MR) is a life-threatening condition presenting with severe decompensated heart failure due to sudden retrograde blood flow into the left atrium. The causes are broadly classified into ischemic and non-ischemic. Rapid and accurate diagnosis of acute MR and its potential causes is essential. This case uniquely highlights an atypical presentation of severe MR secondary to papillary muscle rupture without a known, identifiable cause. Therefore, suspicion of acute MR should be high if clinical symptoms are present, even without known risk factors, due to the high morbidity and mortality associated with delayed management.

Use of plasmapheresis in managing the diagnostic dilemma of symptomatic hypertriglyceridemia.

We present a case study of a 29-year-old male who presented with abdominal pain typical for pancreatitis. Detailed history and investigations revealed that the cause of abdominal pain was secondary to the raised triglyceride levels. It was difficult to distinguish whether he had hypertriglyceridemia-induced abdominal pain or acute pancreatitis, given that he had only a mildly raised lipase and a normal contrast computed tomography scan of the pancreas. The abdominal pain resolved with the fall in the triglyceride levels following plasmapheresis. Plasmapheresis is an underevaluated modality of the treatment of hypertriglyceridemia due to its cost and availability.
