Percutaneous transluminal recanalization for an occluded modified Potts shunt

We performed percutaneous transluminal recanalization successfully for an occluded modified Potts shunt in a 35-year-old man with pulmonary atresia and ventricular septal defect. Percutaneous transluminal recanalization deserves to be considered for occluded shunts if the duration of obstruction is short.
