“Due to the high operative risk because of single ventricle that was right ventricle, sever enlargement of ventricle, systolic dysfunction, low ejection fraction, and atrioventricular”
The corrected sentence appears below:
“Due to the high operative risk with his single right ventricle, severe ventricular enlargement, systolic dysfunction, low ejection fraction, and atrioventricular”
A correction has been made to the Brief case presentation section. The sentence previously stated:
“After procedure SPO2 increased to 70–75% under room air. The patient was admitted to ICU where cardioversion was needed for atrial flutter for 1 day. Due to the previous history of thrombosis, the patient was prescribed rivaroxaban with 2.5 mg dosage twice a day. The patient was discharged with an oxygen saturation of 80% and was prescribed daily aspirin and rivaroxaban. The shunt patency was closely evaluated with ultrasound assessment and is confirmed at 4 months of follow-up, by echocardiography 1 month after discharge, thereafter 3 months later.”
The corrected sentence appears below:
“After the procedure, the SPO2 increased to 70–75% under room air. The patient was admitted to ICU where cardioversion was needed for atrial flutter for 1 day. Due to the previous history of thrombosis, the patient was prescribed rivaroxaban with 2.5 mg dosage twice a day. The patient was discharged with an oxygen saturation of 80% and was prescribed daily aspirin and rivaroxaban. The shunt patency was closely evaluated with ultrasound assessment and confirmed on ultrasound at 1- and 3-months Post-intervention.”
A correction has been made to the Discussion, subsection “Stent implantation for shunt stenosis or occlusion,” subsection “Overview of shunt stenosis or occlusion.” This sentence previously stated:
“Longer stent length, smaller stent diameter, age at the time of surgery, and early discontinuation of anticoagulation medication are also other risk factors for shunt patency”
The corrected sentence appears below:
“Longer stent length, smaller stent diameter, age at the time of surgery, and early discontinuation of anticoagulation medication are also other risk factors for compromising the shunt patency”
A correction has been made to the Discussion, subsection “Stent implantation for shunt stenosis or occlusion,” subsection “Stent implantation for shunt stenosis or occlusion.” The sentence previously stated:
“For the first time in, Zahn et al. successfully exerted angioplasty and stent implantation in an occluded modified BTS in a neonate who underwent a stage 1 Norwood surgery for hypoplastic left heart syndrome and subsequently developed severe cyanosis and hemodynamic instability due to shunt thrombosis (45). In further studies in, stent implantation in occluded central APS was performed in neonates and infants with good results (46, 47). For the first time in, Bader et al. reported transfemoral stenting for alleviation of shunt obstruction in 4 female patients with complex cyanotic heart disease”
The corrected sentence appears below:
“For the first time in 1997, Zahn et al. successfully exerted angioplasty and stent implantation in an occluded modified BTS in a neonate who underwent a stage 1 Norwood surgery for hypoplastic left heart syndrome and subsequently developed severe cyanosis and hemodynamic instability due to shunt thrombosis (45). In further studies, stent implantation in occluded central APS was performed in neonates and infants with good results (46, 47). For the first time in 1999, Bader et al. reported transfemoral stenting for alleviation of shunt obstruction in 4 female patients with complex cyanotic CHD.”
A correction has been made to the Discussion, subsection “Stent implantation for shunt stenosis or occlusion,” subsection “Other treatments of shunt stenosis or occlusion and their challenges,” paragraph one. This sentence previously stated:
“However, several complications and adverse effects such as bleeding and failure of fibrinolytic therapy can occur and thus indicating reoperation. Moreover, fibrinolytic is associated with a higher risk of bleeding in cases of early post-operative shunt thrombosis and is thereby contraindicated in those patients”
The corrected sentence appears below:
“However, several complications and adverse effects such as bleeding and failure of fibrinolytic therapy can occur and thus indicating reoperation. Moreover, fibrinolytic therapy is associated with a higher risk of bleeding in cases of early post-operative shunt thrombosis and is thereby contraindicated in those patients”

A correction has been made to the Discussion, subsection “Follow-up of patients after stent implantation,” subsection “Pediatric patients (<18 years),” paragraph one. This sentence previously stated:
“The follow-up length after stent insertion in failed SPSs reported in the literatures varied from months to years (31, 34, 52). Most studies reported followed of patients within 3–6 months after procedure by measuring oxygen saturation (53, 66, 78, 96), and by catheterization (45), or echocardiography (98) or angiography (66) to evaluate the shunt patency.”
The corrected sentence appears below:
“The follow-up length after stent insertion in failed SPSs reported in the literature varied from months to years (33, 36, 58). Most studies reported on followed of patients within 3–6 months after procedure by measuring oxygen saturation (53, 66, 78, 96), and by catheterization (45), or echocardiography (99) or angiography (66) to evaluate the shunt patency.”
