text: <unk><unk>  can be performed if the anatomy cannot be evaluated on echocardiography.  Although echocardiography is the imaging modality of choice,<unk><unk>  allows confirms the diagnosis and permits collection of additional anatomical and hemodynamic data, including the location and magnitude of right-to-left shunting, the level and severity of right ventricular outflow obstruction, the anatomical features of the right ventricular outflow tract as well as the main pulmonary artery and its branches.  Repair of residual defects following a repair of Tetralogy (leaking VSD, or residual pulmonic narrowing) can also be undertaken percutaneously in experienced centers.
