Abstract The aim of this prospective study is to assess preoperative diagnostic accuracy of echocardiography alone versus complementary cardiac catheterization and their impact on surgical management and outcomes in patients with Fallot’s tetralogy in a trial to adopt a policy for echo guided primary repair. In conclusion, our study suggests that echocardiography alone is an accurate non-invasive tool for preoperative diagnosis of uncomplicated patients with tetralogy of Fallot. It may even obviate the need for routine diagnostic catheterization. Furthermore, echocardiography may complement cardiac catheterization by reducing number of invasive procedures and aiding in the precatherization planning of injection sites by angiography for those with pulmonary atresia and collaterals. Aside from proper anatomical diagnosis, accurate delineation of coronary anatomy is feasible using echo as the sole preoperative diagnostic study in patients with TOF. Preoperative diagnostic cardiac catheterization for the purpose of addressing coronary anatomy is not necessary. |
