A case of cor triatriatum with end-stage renal disease: Successful management of open heart surgery under hemodialysis, subsequent renal transplantation and pregnancy

A female patient who had open heart surgery for cor triatriatum under hemodialysis, subsequent kidney transplantation and pregnancy is reported. We performed hemodialysis on the patient before, during and after heart surgery to control renal failure. Two years after heart surgery, she received a kidney graft from her mother. The kidney graft showed good function. She was treated with azathioprine and prednisone. Three years after renal transplantation she delivered a healthy male infant by elective Caesarean section at 37 weeks' gestation. Mother and infant did well following delivery. There was lack of hypertension, proteinuria, signs of graft rejection, and recurrence of heart failure during pregnancy. She showed serum creatinine level < 2 mg/dl, a prednisone of < 2 mg/kg/day. Elective Caesarean section has improved hydronephrosis due to the compression of the fetus. The aforementioned good criteria contributed to the successful pregnancy of the renal transplant patient in our experience. We believe early surgical intervention overcomes complicated heart disease even with endstage renal disease, and it gives a chance to receive renal transplantation and have a healthy child. To our knowledge, this is the first report that has described the successful management of open heart surgery under hemodialysis, subsequent renal transplantation and pregnancy in a female patient with chronic renal failure.
