Preoperative management for tricuspid regurgitation in hypoplastic left heart syndrome

Background:  Tricuspid regurgitation (TR) is an important finding in hypoplastic left heart syndrome (HLHS). The aim of the present study was to investigate changes in the degree of TR after the preoperative management of HLHS with mechanical ventilation, and whether the improvement of TR under preoperative management would affect the short‐term prognosis of Norwood operation.
