A technique for cardioplegic infusion and left heart venting during coronary artery bypass grafting
B Schneider, VR Conti and M Kurusz
A method for administering cardioplegia and venting the left heart that
utilizes a single cannula in the aortic root and minimizes the risk of air
entering the left heart is presented. This technique permits precise
control of flow and pressure of the cardioplegic solution. Left heart
decompression is accomplished by siphon drainage with controlled negative
pressure. This method effectively vents the left heart while preventing
aspiration of air around the cannula insertion site or retrograde through
an opened coronary artery with a nonocclusive proximal lesion during the
construction of the distal anastomoses.
