Thank you for your query.
I can understand your concern. PAPVC stands for Partial Anomalous Pulmonary Venous Connection which is a congenital heart anomaly which may be associated with other cardiac and/or other organ anomalies. After a complete work up the correct line of management is decided. Cardiac surgery
may be required.
As mentioned earlier other organ anomalies may be present and you have enquired about kidney
problem which needs to be investigated and managed accordingly.
I hope I have answered your query to your satisfaction.
Wishing your son all the best.
