From Hip to Heart: Cobalt-induced Cardiomyopathy Requiring Cardiac Transplantation
We describe a case of cobalt-induced cardiomyopathy that progressed to end stage heart failure requiring orthotopic heart transplantation. A 67 year old woman with history of bilateral cobalt-chromium hip replacements presented with dyspnea of 3 weeks duration. She was tachycardic and hypotensive, with elevated NT- proBNP. Electrocardiogram demonstrated sinus tachycardia, low voltage and right bundle branch block. Transthoracic echocardiogram revealed left ventricular ejection fraction of 20-25% with global hypokinesis and a moderate circumferential pericardial effusion.
