Abstract

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. Abstract : During left ventricular assist device implantation, right ventricle vascularization safeguard becomes capital to avoid postoperative right heart failure. The "Step sideways" technique represents a middle‐way between the apical and the diaphragmatic insertion of the inflow cannula, since it consists of a moderate lateral and inferior relocation of the sewing ring, allowing both the respect of a left anterior descending coronary artery supplying an occluded right coronary and the maintenance of a sufficient mitral coaxiality for correct left ventricular unloading.
