Cardioplegia Considerations
The EndoClamp catheter can be utilized to facilitate endo-
vascular aortic cross-clamping, antegrade cardioplegia
delivery, aortic root venting, and aortic root pressure mon-
itoring during mitral valve or right-heart procedures.

The
EndoClamp is advanced through the EndoArterial Return
cannula, up the descending aorta and into the ascending
aorta under TEE guidance. The EndoClamp incorporates a
balloon that is inflated with saline via a separate lumen to
occlude the aorta. Once the balloon is occlusive, antegrade
cardioplegia is delivered through a separate lumen to arrest
the heart. Strict attention must be given to the aortic root
pressure, balloon pressure, right radial pressure, and TEE
to confirm appropriate placement of the balloon and effec-
tive cardioplegia delivery.
The ProPlege sinus catheter and EndoVent pulmonary
artery (PA) catheters are also available from Edwards to
facilitate retrograde cardioplegia delivery and PA venting.
These cannulas are also part of the ThruPort procedure and
are inserted percutaneously via the RIJ vein.
The most common strategy for cardioplegia delivery in
minimally invasive procedures is via direct cannulation of
the aorta, with a long 7-Fr (14 Ga) cardioplegia needle (Sorin
