Chylothorax and chylopericardium following mitral and tricuspid valve repairs and radiofrequency maze procedure.

Surgical radiofrequency Maze procedure is a well-developed technology with an established safety profile. Clinical complications, albeit rare, have been described secondary to usage of unipolar radiofrequency devices. Bipolar radiofrequency devices have virtually eliminated the complications associated with unipolar devices, thereby combining safety with efficacy. We report a case of chylopericardial tamponade and chylothorax following radiofrequency Maze procedure using a bipolar device.
