Integrated Percutaneous Atrial Septal Defect Occlusion and Pulmonary Balloon Valvuloplasty

Introduction: Atrial Septal Defect (ASD) is one of the most common congenital heart diseases during childhood. Today, ASD closure is done by occlutech device via cardiac catheterization. ASD repair with transcatheter technique has shown high closure rate. However, coexistence of severe pulmonary stenosis and large defect in atrial septum is rare. When these two problems coexist, the result is i...

Superior QRS axis in ventricular septal defect.

The relation between the superior orientation of the QRS axis and the anatomical site of the defect in the ventricular septum in patients with a ventricular septal defect was studied. Of 1031 patients with a ventricular septal defect, 64 (6.2%) had a superior axis on their electrocardiogram. In 59% of these patients the defect was in the inlet portion of the ventricular septum or affected this ...

Electrocardiogram of secumdum type atrial septal defect simulating endocardial cushion defect.

Three groups of patients are identified in the series of secumdum atrial septal defect with left axis deviation in an analysis of 910 patients of secundum atrial septal defect with or without other accompanying anomalies: 1) 12 patients with isolated ostium secumdum defect; 2) 5 patients with associated prolapse of posterior leaflet of the mitral valve; 3) 4 patients with associated hypertrophi...
