Comparative Study
[Superior results of ketone body ratio in pulsatile normothermic cardiopulmonary bypass; comparison with non-pulsatile cardiopulmonary bypass].
Sixteen patients undergoing aortocoronary bypass surgery under normothermic cardiopulmonary bypass were divided into 2 groups according to the either addition or none of pulsatility induced by intra-aortic balloon pumping (IABP). In those patients, hepatic blood flow was measured 3 times before, during and after cardiopulmonary bypass. Additionally, arterial and hepatic ketone body ratios [(AKBR) and (HKBR)], and hepatic venous saturation (ShvO2) were measured throughout and after the surgery. ⋯ Pulsatile normothermic cardiopulmonary bypass induced by IABP provides better liver perfusion and results in a better hepatic metabolism than non-pulsatile cardiopulmonary bypass.

An association between bicuspid aortic valve disease and ascending aortic aneurysma has long been recognized. Root replacement with a composite valve graft for such disease is a well-established technique. ⋯ Angiographic studies after surgery showed no residual aortic regurgitation (AR) and no deformity of aorta. This technique is an acceptable option for an aortic disease and ascending aneurysma in elderly patients.
