The utility of live three-dimensional echocardiography in the surgical treatment of bilateral coronary fistulas.

In patients with coronary and pulmonary arterial fistulas, the drainage sites may be difficult to identify if there are multiple connections by standard 2D echocardiography techniques. However, real time 3D TEE was used intraoperatively in our case to facilitate site identification, the number of fistulous connections, and documentation of the fistula ligation.
