Background : The hemodynamic energies which are generated by a pulsatile pump were delivered differently by an ECMO circuit component. We evaluated the hemodynamic energies amount which were delivered to both carotid arteries in a patient specific 3D printed mock circuit according to aortic cannula geometries.
Methods : We made a patient specific aortic model based on an aortic stenosis patient CT images with 3D printed mold and silicone. This hollow silicone aorta model was connected to the Donovan type mock system and a pulsatile pump. We inserted 3 different aortic cannula in the aorta silicone model. 24 Fr and 35㎝ length straight tip cannula (EZ GlideTM Aortic Cannula, Edwards lifesciencesTM, Germany), 24Fr and 37.6㎝ length curved tip cannula (EZ GlideTM Aortic Cannula, Edwards lifesciencesTM, Germany), and 24Fr and 20㎝ length straight tip cannula (Aortic Perfusion Cannula, Edwards lifesciencesTM, Germany) were used. We measured hemodynamic energy on both carotid arteries of the aorta model.
Results : Every component of hemodynamic energy on both carotid arteries were different according to cannula geometries (Table 1).
Conclusion : The hemodynamic energies amount which were delivered to both carotid arteries were affected by the cannula tip shape or length of the aortic cannula even though the cannula size were same as 24 Fr.
