A 50-year-old man presented with flu-like symptoms, breathlessness and palpitations. He was in atrial fibrillation on admission and a subsequent transthoracic echocardiogram revealed severe left ventricular impairment. A working diagnosis of viral cardiomyopathy was made and he was commenced on anticoagulation, an angiotensin converting enzyme inhibitor and digoxin.
A week into his admission, he complained of severe right flank pain and developed acute renal failure. Magnetic resonance imaging (MRI) of his abdomen showed evidence of haemorrhagic infarcts in his right kidney and also a splenic infarct suggesting embolic phenomenon (fig 1A,B). His left kidney was noted to be shrunken. A transoesophageal echocardiogram showed left atrial appendage thrombus (fig 1C) which could not be seen on the initial transthoracic study.
