Abstract: 

Background: With attention to association of right atrial pressure to renal venous hypertension , we try to review renal function indices changing due to congenital heart disease as base of right atrial pressure and cyanosis condition.
Methods: Forty five children without preexisting renal disease, diagnosed as pulmonary hypertension due to congenital heart disease with or without cyanosis entered to this study, their renal function indices besides to their right atrial pressure measured by angiographic documents .The effects of right atrial pressure and cyanosis on renal function indices evaluated by appropriate statistical methods.
Results: Right atrial pressure is not a common problem but it is more frequent in cyanotic than acyanotic patients. In addition significant proteinuria occurs in cyanotic patients with high right atrial pressure (above 5 mmHg). There is not any difference between renal function as glomerular filtration rate or creatinine in either groups of cyantic or acyanotic with a high or normal right atrial pressure.
Conclusion: In cyanotic congenital heart disease patients who have pulmonary hypertension measuring of right atrial pressure seems essential; in high risk group including those with high right atrial pressure and cyanosis, significant proteinuria may happen in up to 30% of cases independent of age or gender.
