|---|
Although minimally invasive cardiac surgery is being more popular in these days, how we treat the unpredictable intraoperative complication is very important. We report a successful case of minimally invasive aortic valve replacement complicated with an intraoperative acute aortic dissection. We coped with this complication by replacing the ascending aorta with a mini-incision under deep hypothermic circulatory arrest with retrograde cerebral perfusion. Expanding the sternotomy was not done simply because this was felt that it would not provide any additional required exposure for treatment of the dissection. We need to keep in mind that the possibility of having unpredictable complication like this case during minimally invasive surgery.
