Abstract

Introduction:

Right ventricular outflow tract stenting has emerged as a key palliative intervention for infants with tetralogy of Fallot who are not suitable candidates for complete repair. Although the Blalock-Taussig shunt remains the standard palliative approach for tetralogy of Fallot patients over one year of age, the potential of right ventricular outflow tract stenting in this older age group has not been widely explored. In this study, we present our experience with right ventricular outflow tract stenting in children beyond one year of age.

Methods and Results:

In this study, a total of 52 patients of tetralogy of Fallot who underwent palliative stenting of the right ventricular outflow tract from 2018 to 2022 were enrolled. Out of the 52 patients, 38 children were more than 1 year of age with a mean age of 4.82 ± 3.5 (1.5–13 years) and mean weight of 13.10 ± 7.0 (5.6–34) kgs. Most common indication was presence of unfavourable anatomy in 27 (71%) followed by presence of refractory spells in 14 (36.8%) patients. Stent embolisation was seen in one patient, while two patients developed features of pulmonary oedema and needed prolonged ventilatory support. There was no mortality seen in this study group.

Conclusion:

Our study has shown that right ventricular outflow tract stenting in children even beyond one year of age is technically feasible, with good immediate outcomes, especially in those who present with any complication, thus reducing the perioperative morbidity and mortality.
