- a Echo data were available for all patients. F, females; RA, right atrium; RAP, right atrium pressure; RVP, right ventricle pressure. A patent foramen ovalis (PFO) was considered to be present when described in the echo referral or in the surgical report In 17 out of 18 patients with TOF and PFO, a right to left shunt was present. In the latter the shunt across the PFO was bidirectional. Five patients with VSD had a left to right shunt across the PFO.
- bThe right atrium was described as “enlarged” by the surgeon in all 46 patients. Echocardiographic data are reported in the table.
- cPreoperative cardiac catheterization was performed in 12 (52.1%) patients with TOF, 3 (30.0%) patients with VSD and 5 (38.5%) patients with ASD. In ASD patients, cardiac catheterization was always performed in concomitance with an attempt at percutaneous closure of the defect.
