Early reversible cardiomyopathy post parathyroidectomy: A case report

We report a case of a 13-year-old girl presenting with symptoms that were suggestive of cardiomyopathy on the 12th postoperative day following the removal of a “giant” parathyroid adenoma using Focused Parathyroidectomy (PTX) with Intraoperative Parathormone monitoring. The patient had developed facial puffiness and body edema. An echocardiographic examination revealed moderate mitral regurgitation and dilated left atrium and left ventricular ejection fraction of 30%. Treatment was focused to reduce volume overload. One-month follow-up revealed that the patient was healthy and had no cardiac symptoms on the subsequent 3-month follow-up. Postoperative early transient reversible cardiomyopathy post PTX is very rare and to the best of our knowledge, only five cases have been reported so far. Our patient’s case is unique in that it highlights the risk of Hungry Bone Syndrome, early transient reversible cardiomyopathy, in an otherwise healthy child. It is important to elaborate on this complication to diagnose and treat this condition adequately.
