A 22-year-old male undergoing aortic valve replacement was found to have the left coronary ostium arising from the noncoronary cusp area in close proximity to the annulus. He could not be weaned off cardiopulmonary bypass after the operation, even after removal of a Teflon pledget thought to obstruct the left coronary ostium. He underwent bypass grafting to the left coronary system and was then easily weaned off cardiopulmonary bypass.
