Echocardiographic evaluation of the morphology and function of the right ventricle in Eisenmenger's syndrome and idiopathic pulmonary hypertension.
The aim of this study was to investigate the reasons for better prognosis in adults with Eisenmenger's syndrome than those suffering from idiopathic pulmonary hypertension. Our hypothesis was that right ventricular function is better preserved in the former case than in the latter. ⋯ Right ventricular function was better preserved among subjects with Eisenmenger's syndrome than those with idiopathic pulmonary hypertension in a study in which the two groups were matched for age and sex.

Transcatheter closure of fossa ovalis atrial septal defect: a single institutional experience.
Transcatheter closure of the fossa ovalis atrial septal defect with adequate rims has become the procedure of choice in recent times. We report our experience with 439 patients who were selected for percutaneous device closure and 430 of whom underwent transcatheter closure of fossa ovalis atrial septal defects from May 1997 to May 2006. Device closure was not attempted in the remaining nine patients after initial evaluation due to high right atrial pressure following balloon occlusion (n=1 not parallel, high pulmonary vascular resistance (n=1), significant coronary artery disease (n=1), or the fact that the atrial septal defect was unsuitable for device closure (n=6). ⋯ The immediate success rate of device closure was 96.9%. All but one patient with multiple defects had no residual shunt at follow-up. On three months' to nine years' follow-up, the device remained stable, with no significant residual shunt and no history of thrombus formation on transthoracic echocardiography.
