This case report describes a modification in the technique of atrial septal device closure in a patient with atrial septal defect (ASD) with associated atrial septum aneurysm and significant left-to-right shunt through multiple perforations. Graded balloon dilatation of the aneurysm was performed in this patient, as a preamble to successful deployment of a single large Amplatzer atrial septal o...

INTERATRIAL SEPTAL DISORDERS, WHICH INCLUDE: atrial septal defect, patent foramen ovale and atrial septal aneurysm, are frequent congenital anomalies found in adult patients. Early detection of these anomalies is important to prevent their hemodynamic and/or thromboembolic consequences. The aims of this study were: to assess the association between impulse conduction disorders and anomalies of ...

In a series of more than 3500 pregnancies referred for fetal echocardiography, 29 cases of atrioventricular septal defect were detected in the fetus. There was a chromosomal anomaly in 14 of these cases, left atrial isomerism in 12, and right atrial isomerism in two. Complete heart block was found in 11 of the cases with left atrial isomerism. Many associated cardiac abnormalities were found, p...

Twelve adult patients with ostium primum atrial septal defects (incomplete endocardial cushion defect) who underwent surgical repair of their lesions were evaluated in the late postoperative period. All had closure of the low-lying atrial septal defect, with suturing of the mitral valve cleft in 11 patients. Although the patients benefited symptomatically from the surgery, all had residual card...

Five cases of atrial septal defect are reported, each of which was associated with a cleft in the anterior or posterior (or both) leaflet of the mitral valve. Only 3 had a characteristic murmur of mitral regurgitation, and 2 of these patients were thought to have a partial endocardial cushion defect. In two patients, the discovery of the mitral valve cleft came only at the time of operation, wh...
