Fig 1 Aortic cannulation using apical Berlin Heart cannula and a 8 mm Gore-Tex tube. Note the shorter side of the beveled cannula is oriented superiorly to prevent potential kinking.

Fig 2 (A) Atrial Berlin Heart cannula has a “basket,” which is placed deeply into the atrium and may predispose to clot formation. (B) Arterial Berlin Heart cannula used in the atrium, as we propose, does not offer a surface for potential clot formation.

Fig 3 Common atrium cannulation using an arterial Berlin Heart cannula and a purse string suture to flatten out the edges of the atrial tissue, preventing potential encroachment into the lumen of the cannula. Additional pledgeted interrupted sutures are then applied to secure cannula in place.
