An 18 months old boy with TOF benefited from a BTS. Deep cyanosis reappeared 48 hours later and continuous flow profile of the shunt could not be identified by Doppler echocardiography. At catheterization, angiogram confirmed complete shunt occlusion. The shunt was recanalized using a coronary guide wire and a 4mm diameter balloon. The SpO2 improved and repeated Doppler echocardiography showed the patency of the shunt during follow-up. Four days later, he developed a severe febrile pneumopathy due to RSV and died 2 days later. The shunt patency was documented 2 hours before death.
