Medium-Term Outcomes of Kawashima and Completion Fontan Palliation in Single-Ventricle Heart Disease With Heterotaxy and Interrupted Inferior Vena Cava

The KP and subsequent Fontan completion results in acceptable medium-term survival, and remains the approach of choice for single-ventricle heart disease with interrupted inferior vena cava. The KP has to be undertaken with expectation for somewhat lower early Spo2 relative to standard Fontan patients, but in anticipation that Spo2 is likely to rise gradually with time.
