Data are presented as mean ± standard deviation (SD). *P < 0.05 was considered statistically significant. PFO: patent foramen ovale; LA: left atrial anteroposterior diameter; LVEDV: left ventricular end-diastolic volume; LVESV: left ventricular end-systolic volume; IVS: interventricular septal thickness; LVPW: left ventricular posterior wall thickness; LVEF: left ventricular ejection fraction; PAPs: pulmonary artery systolic pressure; ASA: atrial septal aneurysm.
