Cardiorenal syndrome is a disorder of the heart and kidneys in which acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in the other organ. It is well known that the main cause of mortality among patients with end-stage renal disease is due to cardiovascular events and a common complication in patients in acute heart failure is a decrease in renal function. However, when there are no signs and/or symptoms of chronic cardiovascular disease, cardiovascular causes in the etiology of chronic kidney disease is not the first differential considered. We present an 11 year-old girl patient, diagnosed with type 2-chronic cardiorenal syndrome who had previously been followed in another center with the diagnosis of chronic kidney disease for six months and referred to our hospital for kidney biopsy. We present this case to increase awareness of pediatrician and nephrologist about this syndrome.
