Acute kidney injury (AKI) complicates recovery from cardiac surgery in up to 30% of patients, injures and impairs the function of the brain, lungs, and gut, and places patients at a 5-fold increased risk of death during hospitalization.

Norepinephrine is often used to maintain the mean pressure during open heart surgery but it is said that it could constrict cerebral arteries, reducing cerebral blood flow. Is it true? The authors explored the association of Norepi doses and rSO2 measured using near-infrared spectroscopy.

This retrospective study evaluated the relationship between the timing betweenLHC and CABG and its effect on renal function in a cohort of 2371 patients at a single center. Findings included:

Not only an authoritative 16 year retrospective report on 957 planned aortic aneurysm surgeries from Cleveland Clinic, but a stimulating critique ( pages 771-774) with Tyrone David who was the invited discussant of the manuscript at its presentation at the AATS last April.

Data from a large multicenter registry were evaluated to determine whether there is a sex difference in susceptibility to acute kidney injury after CBP related to nadir hematocrit levels. Based on a 21% hematocrit threshold, 9.5% of men and 31.9% of women were affected. Rates of AKI were similar between the sexes. There was a strong interaction be

In this recently published clinical study investigators from Columbia University, New York Presbyterian Hospital evaluated the safety of Del Nido cardioplegia in high-risk CABG surgery after AMI.

Deep hypothermia and cardioplegic myocardial arrest, with or without selective cerebral perfusion, is traditionally performed during aortic arch reconstruction. In this video, the authors describe a technique for selective cerebral perfusion combined with controlled coronary perfusion for hypoplastic aortic arch repair.

Hemodilution on CPB is a hotly debated topic.

Provocative study that analyzes lower body perfusion in a porcine model during cardiopulmonary bypass with an actuated IABP in place to effect pulsatile perfusion. Parameters of distal perfusion including measurement of pressures and microsphere perfusion indicate that flow distal to the balloon pump may be impaired.

This video illustrates the technique used to repair an aortic dissection with a tear involving the aortic root contiguous with the right coronary artery (RCA). In addition to the dissection repair, an aortic root replacement and a jump graft to the RCA are performed.
