Traumatic intracardiac communication: detection by color flow mapping.

A previously healthy 20-year-old man underwent emergency surgery for repair of a right ventricular free wall laceration that was the result of a knife wound. A systolic murmur was first heard 1 month later, and two-dimensional echocardiography and color flow mapping demonstrated a communication between the left and right ventricle in the region of the membranous septum. The visualized turbulent flow was consistent with a ventriculoseptal defect but also appeared to extend posteriorly into the left atrium in a direct line with the septal communication. At cardiac catheterization the calculated left-to-right shunt was 1.2:1.
