Abstract | Full Text

A 55 year-old woman was admitted to the CCU ward of our university hospital due to typical chest pain. The patient received supportive care and was transferred to the operating room for an emergency repair of the ventricular septal defect (VSD) and myocardial revascularization. The surgical team was notified regarding the tolerance to cooling detected by the temperature monitoring and also, the congestion of eye and blanching of forehead. After a few maneuvers, the cannula was repositioned. In a few seconds, the forehead was cooled, while the airlocking episodes were lifted completely and the blanching and chemosis in the face and eyes all resolved. The septal defect was approached through the left ventricle; a 15 in 20 mm foramen, due to the ischemic rupture of the superior portion of the anteroseptal wall, was repaired with a patch of hemoshield. The incision over the LV was then repaired with 2 parallel bands of felt. The patient was operated on and transferred to the intensive care unit.
