Arterial Cannulation Considerations
The surgical procedure and strategy will dictate the arterial
cannulation technique required. The options for cannula-
tion site include ascending aorta, femoral artery, and axil-
lary artery and are outlined in Table 1. The ascending aorta
is commonly used for procedures that include an upper- or
lower-hemisternotomy—for example, aortic or mitral
valve procedures. The aorta can also be cannulated directly
via the thoracotomy incision.

The femoral artery is often used for procedures that uti-
lize a right anterolateral minithoracotomy incision: for
example, the mitral valve, atrial septal defect, or tricuspid
valve repair procedures. Recently an increased risk of neu-
rological complications has been reported with the use of
femoral retrograde perfusion versus central antegrade per-
fusion.
36
However, others have advocated for the screening
of patients at risk for aortoiliac atherosclerosis with con-
trast-enhanced multidetector CT, with avoidance of femo-
ral cannulation in patients with grade IV/V atheroma.
37
In patients who already have preoperative coronary
angiography, our current strategy is to obtain multidetector
CT angiography of the chest, abdomen, and pelvis in all
patients older than 65 years of age or those having a sig-
nificant history of smoking, hypertension, or peripheral
arterial disease. Our evolving strategy is to obtain preop-
erative ECG-gated cardiac CT angiography coupled with a
