Three-Dimensional Image of a Baffle Leak in a Patient with a Mustard Operation

Mini-Abstract Baffle leaks are one type of complication following the Mustard operation for transposition of the great arteries. In this case, a 27-year-old male status post-Mustard operation scheduled for a pacemaker placement was noted to have a positive agitated saline contrast study via transesophageal echocardiography. The baffle leak could not be well defined despite extensive two-dimensional imaging. With three-dimensional imaging, the superior and posterior located baffle leak was clearly imaged. Three-dimensional echocardiography allows unparalleled imaging in identifying the location of baffle leaks in patients with complex intracardiac procedures such as the Mustard operation.
