Left ventricular assist device (LVAD) has emerged as an effective surgical therapy for end-stage heart failure. In an attempt to reduce invasiveness and avoid difficult sternal re-entries, alternative surgical approaches have been adopted. In particular, when the thoracic aorta is severely diseased or difficult to expose, subclavian arteries could serve as site for outflow graft anastomosis. However, major concerns regarding the utilization of subclavian arteries are the small caliber of these vessels that could lead to inadequate LVAD flow, arm complications related to excessive blood flow, and possible outflow graft compression. In the present case series, we describe an innovative technique for LVAD implantation, in which the left subclavian artery was employed as an outflow graft anastomosis site, and the left ventricular apex was approached through a mini-thoracotomy. Technical issues were considered to prevent possible complications: the adequacy of left subclavian artery diameter, the banding of the artery distal to the anastomosis site to limit left arm overflow, and the outflow graft covering with a reinforced vascular graft to avoid any external compression. During follow-up, the technique reported was found to be effective in ensuring good LVAD function and flow, and no complications related to the procedure were reported.
