Comparative StudyRequirement for renal replacement therapy in patients undergoing cardiac surgery.
Despite refinements in perioperative patient management renal insufficiency requiring renal replacement therapy (RRT) is still a common complication after cardiac surgical procedures associated with impaired patient outcome and increased costs. ⋯ Identifying perioperative risk factors associated with postoperative RRT will help to reduce the incidence of this complication. Avoiding cardiopulmonary bypass seem to be beneficial with regard to the prevalence of postoperative RRT.

Case ReportsClinical surgical experience of congenital submitral left ventricular aneurysm.
Submitral left ventricular aneurysm is a rare cardiac pathology, occurring almost exclusively in black African patients. Two cases treated in our institute are reported in the present report. One is a 10-year-old boy with submitral aneurysm and mitral regurgitation, who underwent mitral valve repair and exclusion of the aneurysm with a left atrial approach. ⋯ The aneurysm was excluded by a Dacron patch from outside the left ventricle in addition to cryoablation on the endocardium of the aneurysm. Both patients recovered well after the operation. The present report presents two cases of this rare disease with different surgical approaches.

Comparative StudyChanges in regional cerebral blood flow under hypothermic selective cerebral perfusion.
Currently the most frequently used perfusion technique during aortic arch surgery to prevent cerebral damage is hypothermic selective cerebral perfusion (SCP). Changes in cerebral blood flow (CBF) are known to occur during these procedures. We investigated regional changes of CBF under conditions of SCP in a porcine model. ⋯ SCP improves CBF in all regions of the brain. Our study characterizes the brain specific hierarchy of blood flow during SCP and total body perfusion. These dynamics are highly relevant for clinical strategies of perfusion.
