Echocardiography is the preferred diagnostic tool in the evaluation of an<unk><unk><unk> . Out of the different types of echocardiographic modalities that can be used, transesophageal echocardiography can be used for all types of<unk><unk><unk> s.<unk> s have shown transesophageal echocardiography to be superior in diagnosing sinus venosus ASD compared to transthoracic echocardiography. Other modalities like transthoracic echocardiography can be used for identification of the secundum type of<unk><unk><unk> s. During imaging the entire<unk>  septum from the orifice of the superior vena cava to the orifice of the inferior vena cava should be visualized. This helps in<unk> ing sinus venosus<unk> s and large ostium secundum<unk> s that might extend up to that area. As an evaluative tool, echocardiograms can: locate the<unk> s, identify the direction of shunting, identify associated anomalies, evaluate<unk>  and ventricular enlargement. In general, an<unk><unk><unk>  patient will present symptomatic evidence of hemodynamic disruptions between the left and right atrium.
