Abstract

Introduction:

Modified Blalock-Taussig shunt (BT shunt) is a palliative operation used for cyanotic heart diseases with decreased pulmonary blood supply. The definitive management of tetralogy of Fallot (TOF) is total corrective surgery, but these patients can be palliated with BT shunt. In the modern world, the BT shunt is getting out of favour in patients with TOF. In this article, we will share our 5-year experience at our institute, which also shows a decreasing trend.

Patients and methods:

It is a retrospective study. Files of all the patients admitted in our department from January 2019 to December 2023 were reviewed. Age, weight, hospital stay, inotropic support duration, mechanical ventilation duration, and outcomes were studied.

Results:

From January 2019 to December 2023, 173 patients underwent BT shunt for TOF. The mean age was 31 months, and the mean weight was 9.3 kg. The overall mortality for BT shunt was 15% after BT shunt. Hypercyanotic spell not controlled by medical management was the most common indication for BT shunt in our setup. Most of the patients with hypercyanotic spells were also candidates for total correction but due to the emergency, BT shunt was performed.

Conclusion:

The role of BT shunt in patients with TOF is decreasing due to PDA/RVOT stenting, it is likely that the BT shunt in TOF will become a thing of the past in the future even in developing countries like ours.
