    Abstract:
    Surgical correction of ostium secundum atrial septal defects may be performed, in most cases, without cardiac catheterization, on the ground of clinical and two-dimensional echocardiographic (2D echo) findings. Consequently it's useful to identify the reliability of 2D echo and the indications for angiography in these patients (pts). One hundred forty-five patients operated in "A. De Gasperis" Division of Cardiac Surgery in Milan from January 1982 to December 1986 are reviewed. Patients with ostium primum atrial septal defects or subjected to cardiac catheterization and angiography in other institutions are excluded. Altogether two-dimensional echocardiography was performed in 131 pts, cardiac catheterization in 78. Sixty-four pts were studied with both 2D echo and angiography. In 35 pts (with only 2D echo examination) radionuclide angiocardiography was performed. The results of the different techniques were compared with intra-operative findings, defining sensitivity and specificity in relation to detection of the site of the defect and of the pulmonary venous return. There were no statistically significative differences between echo 2D and cardiac catheterization (Figs. 1 and 2). Two-dimensional echocardiography confirms its cost effective and psychological advantages, especially in younger patients. Hemodynamic and angiographic assessment should be performed as follows: 1) when associated anomalies are suspected; 2) in cases of non-satisfying quality of the 2D echo examination; 3) when diagnostic incoherence between clinical and instrumental data is present; 4) in patients with pulmonary hypertension.
