Abstract | OBJECTIVE: METHODS: Between July 2009 and February 2011, six patients with TGAs, VSD, and severe PAH (mean age 39.8 ± 47.4 months, median 21, range 8-132 months), weighing 10.7 ± 9.2 kg (median 8.6, range 4.3-29 kg), underwent ASO with VSD closure using our simple technique of UVP. Mean pulmonary artery systolic pressure before the operation was 106 ± 12.7 mm Hg (median 107.5, range 95-126 mm Hg) and pulmonary vascular resistance was 9.5 ± 4.22 units (median 9.5, range 6.6-17.1 Wood units). RESULTS: There were no deaths. All patients had a postoperative systemic arterial saturation of more than 95%, although there were frequent episodes of systemic desaturation due to right-to-left shunt across the valved VSD patch (as seen on transesophageal and transthoracic echocardiograms). Mean follow-up was 10 ± 7.6 months (median 7.5, range 1-22 months). At most recent follow-up, all patients had systemic arterial saturation of more than 95% and no right-to-left shunt through the VSD patch. In one patient, the follow-up cardiac catheterization showed a fall in pulmonary artery systolic pressure to 49 mm Hg. CONCLUSION:
Arterial switch operation with UVP VSD closure is feasible with acceptable early results. It avoids complications of palliative atrial switch ( arrhythmia and baffle obstruction) and partially or completely open VSD.
