Margins around the defect
Data are presented as mean ± standard deviation or as number (percentage) of patients. ASD = atrial septal defect. SVC = superior vena cava. AV = atrioven- tricular valve. IVC = inferior vena cava. LA = left Atrium. A-P = anterior-poste- rior. MV = mitral valve. LVEDD = left ventricular end diastolic dimension. LVSF = left ventricle shortening fraction. TV = tricuspid valve; RV = right ventricle.
device-related parameters, hemodynamic parame- ters, and procedure-related details.
The patients in group II were signi cantly younger, lighter and shorter than those in group I: (4.5 years SD 3.9 vs. 6.9 years SD 3.9; p = 0.009), (15.1 kg SD 8.06 vs. 21.9 kg SD 11.8; p = 0.013), (96.9 cm SD 16.8 vs. 114.6 cm SD 20.04; p < 0.001).
Defect (ASD), atrial septum and adjacent structures
The ratio of ASD size (mm) in relation to the patient weight (kg) and length (cm) was signi cantly larger in group II patients: (0.93 SD 0.37 vs. 0.64 SD 0.28; p < 0.001), (0.13 SD 0.04 vs. 0.1 SD 0.03; p = 0.014), re- spectively. Incidence of all non-numerical variables was higher in group II but these di erences did not reach statistical signi cance.
