Two cases with isolated and complex cardiac defects together with inferior vena cava anomaly

Systemic venous anomalies are rare congenital anomalies.Although they appear in different symptoms, they areusually asymptomatic and they can be detected incidentallyduring investigation of other congenital heart anomalies.The knowledge of this kind of anomalies before cardiacangiography and open heart surgery is important toprevent time loss and unexpected complications. Echocardiographytransabdominal view is used and angiographyis performed for confirmation. We report two casesin which absent suprarenal inferior vena cava with venaazygos continuity was present. One is isolated and one ispresent with cardiac atrioventricular septal defect
