Abstract:

Objective: The use of a valved Sano at the time of stage I palliation has been reported previously, but its impact on clinical outcomes needs to be further elucidated. We assessed the impact of the valved Sano compared to the non-valved Sano following stage I palliation in HLHS patients.
Methods: We retrospectively reviewed 25 consecutive HLHS neonates who underwent a valved Sano (VS) stage I operation using a femoral venous homograft and 25 consecutive HLHS neonates who underwent a standard non-valved Sano (NVS) between 2014 and 2022. Primary outcomes were ventricular function, tricuspid regurgitation, end-organ function, Sano and pulmonary artery (PA) reintervention, and survival at post-operative, discharge, interstage, and pre-Glenn time points.
Results: Perioperative characteristics and outcomes are summarized in Figure 1A. VS had a significantly lower peak lactate level (p=0.049), lactate 24 hours after peaking (p=0.02), time to diuresis (p=0.04), time to enteral feeds (p=0.02), and time to extubation (trend, p=0.08). No significant differences in mortality were seen during the hospital stay and interstage period (Fig 1A-C). The VS group had fewer patients requiring ECMO, experiencing cardiac arrest, and undergoing Sano and PA reinterventions prior to discharge following the Norwood operation (Fig 1A&B). The VS group trended towards fewer PA reinterventions overall (1 vs 7; p=0.116). Despite having worse ventricular function at baseline, the VS group showed significant improvement from the immediate post-operative period to discharge (Fig 1D arrow; p< 0.001). From preoperative to pre-Glenn time points, ventricular function within the VS was sustained, whereas ventricular function in the NVS group was significantly reduced by the time of pre-Glenn (Fig 1D; P<0.002). Pre-Glenn echocardiograms showed competent conduit valves in majority of the VS patients (n=16; 64%).
Conclusions: The VS is, or tends to be, associated with 1) improved multi-organ recovery and stability postoperatively, as demonstrated by lower lactate levels, time to diuresis, time to enteral feeds, and time to extubation; 2) increased hemodynamic stability, as exhibited by fewer patients needing ECMO or experiencing cardiac arrest postoperatively; 3) fewer PA reinterventions until stage II; and 4) augmented ventricular function recovery during stage I hospital stay. Assessment of mid- and long-term outcomes is warranted to evaluate the impact of valved Sano after stages II and III.
