Changes in right ventricular function in neonates with hypoplastic left heart syndrome before and after the hybrid procedure.

Aims: Decreased right ventricular function via deformation analysis has been noted in patients with hypoplastic left heart syndrome (HLHS) after the Norwood procedure. No data exist in HLHS patients undergoing the hybrid procedure. The goal of this study was to evaluate right ventricular functional changes in HLHS patients undergoing the hybrid procedure under steady-state conditions.

Interstage echocardiographic changes in patients undergoing hybrid stage I palliation for hypoplastic left heart syndrome.

Objective: The hybrid procedure is an alternative for initial palliation for patients with hypoplastic left heart syndrome. No echocardiographic data exist for the interstage (IS) period. The goal of this study was to describe the echocardiographic changes during this period.
