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.
