Patient Selection
Patients with HLHS who had undergone HP with one or more further
interventions on the atrial septum, prior to the second palliation, were
identified from the departmental database (HeartSuite). Patients with
atrioventricular and ventriculoarterial concordance with mitral and
aortic stenosis or atresia, with no significant ventricular septal
defects were included. Patients with other variants such as unbalanced
atrioventricular septal defects or double outlet right ventricle were
excluded. Patient demographics along with the date of procedures were
recorded. Further procedures and current status were recorded from the
same departmental database.
Echocardiograms were identified, reviewed and analysed on the Philips
Xcelera workstation. Time-points for analysis were:
- Within 24 hours of hybrid procedure
- Prior to atrial septal intervention
- Post atrial septal intervention
