Abstract

We describe pitfalls of a hitherto undetected patent foramen ovale during the conduct of an off-bypass coronary revascularization. Manipulation of the heart resulted in right-to-left shunt and severe desaturation requiring institution of cardiopulmonary bypass to close the patent foramen ovale and complete the revascularization.
