OP-183 Experience with Three-Dimensional Transesophageal Echocardiography During Percutaneous Closure of Atrial Septal Defects

A and 0.364 accordingly). Pre-exercise, peak-exercise and postexercise BNP and troponin I values were similar across the groups (p>0.05 for all comparisons). Serum copeptin values for preexercise and peak-exercise were similar among all groups (p1⁄40.883 and 0.089). Postexercise copeptin value of the normal and equivocal groups were similar (p1⁄40.661 z1⁄4-0.438) while that of the ischemia group was significantly higher than both normal group (p<0.001 z1⁄4-4.612) and equivocal group (p<0.001 z1⁄4-4.440). Conclusions: Serum copeptin was found to be increasing significantly in case of ischemia on MPS. It may be used in differentitaion of equivocal results from false positive results. B S -OP-183
