Left ventricular assist device inflow cannula implantation: Why a "Step sideways" technique can be helpful.

ABSTRACT

Preservation of right ventricle vascularization that is dependent on left coronary network collateral development is essential during left ventricular assist device implantation to avoid postoperative right heart failure. Our technique was performed on a patient who underwent implantation as a bridge to transplantation; the technique is characterized by providing a moderate lateral and inferior displacement of the inflow cannula position, which achieves both the objectives of respecting the apical course of a left anterior descending coronary artery supplying an occluded right coronary and of maintaining a sufficient orientation degree toward the plane of the mitral valve for correct left ventricular unloading.
