This study shows that in univentricular physiology cerebral oxygen saturation correlates well with jugular venous oxygen saturation, arterial oxygen saturation, and arterial oxygen content. However, our findings suggest that in singe-ventricle physiology changes in cerebral oxygen saturation need to be interpreted in the context of changes in arterial oxygenation.

Patients with LMCD can undergo OPCAB grafting safely and effectively despite reduced LVEF. LMCD should no longer be seen as a contraindication to perform OPCAB grafting.

A new technique of myocardial protection was utilized in performing surgery for acute type-A dissection involving the aortic valve, requiring replacement of the root. Simultaneous antegrade and retrograde perfusion of the heart with normothermic blood at high flows allows for safe and precise surgery, without concerns for the period of aortic clamping, since ischemia is eliminated altogether.
