Adjustment of the surgical plan in repair of congenital heart disease: the power of cross-sectional imaging and three-dimensional visualization.

The purpose of this article is to study the importance of cross-sectional imaging in preoperative evaluation and surgical planning. Echocardiography is the modality of choice to diagnose cardiac diseases. However, in some cases, the data obtained from echocardiogram are insufficient or the image quality is poor. In these cases, additional modalities are being used to provide further information that can aid in guiding medical management of or surgical planning for the patient. Cross-sectional imaging has become widely available in many institutions. These imaging techniques, especially with three-dimensional reconstructions, provide realistic images that have imperative diagnostic values. Moreover, the possibility of sophisticated image-processing techniques provides important hemodynamic characteristics via less invasive methods. In this article, we present three cases in which additional cross-sectional imaging seemed to be a crucial step prior to surgical planning.
