Background: Residual shunt after the closure of an inferior sinus venosus defect (ISVD) is a rare complication with a high rate of reintervention.
Case presentation: Here, we report a rare case of a patient with a recurrent defect identified 22 years after the closure of ISVD. The 25 × 10-mm defect was situated at the inferior vena cava–right atrial junction and was closed directly at 5 years of age. No residual shunt was detected, and when the patient reached 12 years of age, follow-up was discontinued. However, the residual atrial septal defect shunt was detected incidentally at 27 years of age. During the second surgery, the lower end of the original defect was opened and then closed using an expanded polytetrafluoroethylene patch.
Conclusions: In light of the high rate of reintervention for residual shunt after ISVD closure, patch closure appeared to be a better option to reduce the tension in the inferior–posterior border. Moreover patients with this profile should be followed up closely at least in their childhood, including assessment by echocardiography.
