The Role of Shunt in The Norwood Procedure

Abstract

Introduction: In this study we observed that the effect of post-Norwood 3.5 mm modified BTS (mBTS) and 5 mm right ventricle to pulmonary (Sano modification) shunt models on clinical outcomes.

Patients and Methods: Fifty-four patients who were operated in our hospital between 2011 and 2020 years, were included in our study and this is a retrospective, observational, single-center case series study.

Results: The effect of shunt type on mortality was statistically significant, and the rate of death was lower in patients who used SANO type shunts (p< 0.05). The effect of vasoactive inotropic score (VISC score) on early mortality was significant, and VISC score was higher in the group with exitus (p< 0.05).

Conclusion: Although Sano shunt seems more preferred in Norwood, the experience of the surgeon and the center’s experience may have led to variation in results at hypoplastic left heart syndrome. Nevertheless, it will be clinically important for studies to evaluate the long-term results between the two shunt types.
