Introduction
With the development of diagnostic methods, the incidence of some congenital anomalies is increasing. One of them is the anomalous pulmonary venous return (APVR). This congenital problem, first described by Winslow in 1739, is characterized by the drainage of all or part of the pulmonary veins into the systemic venous circulation or the right atrium (1). This anomaly, which creates a volume load in the right chambers due to the left-right shunt, is frequently detected together with other congenital heart anomalies, especially atrial septal defect (2). However, in this case, we will try to present the coexistence of iatrogenic, not congenital, ASD and PAPVR in an adult female patient with rheumatic mitral stenosis.
