A simple method of creating LVAD outflow tract aortic anastomosis.
نویسندگان
چکیده
Left ventricular assist device (LVAD) implantation is frequently complicated by intraoperative and postoperative bleeding, particularly at the aortic anastomosis site. Many modifications of the anastomosis have been attempted. We describe a simple method to anastomose the LVAD outflow tract to the ascending aorta with minimal bleeding and a short anastomosis time.

Left ventricular assist device outflow graft: alternative sites.
We describe three alternative approaches for the left ventricular assist device (LVAD) outflow graft during implantation of the LVAD. The supraceliac abdominal aorta, innominate artery and left axillary artery were employed as alternative sites for the LVAD outflow graft in the setting of a heavily calcified ascending aorta or a hostile chest wall and mediastinum. The first approach involved th...

Axial-flow ventricular assist devices (VADs) can be implanted either through a left thoracotomy with outflow-graft anastomosis to the descending thoracic aorta or through a midline sternotomy with anastomosis to the ascending aorta. Each method has advantages and disadvantages. Because these VADs produce nonpulsatile flow, their hemodynamic characteristics differ from those of pulsatile devices...

A 76-year-old man with severe degenerative aortic stenosis, coronary artery disease, and progressive congestive heart failure with severe systolic dysfunction underwent implantation of a Heartmate II left ventricular assist device (LVAD; Thoratec Corporation, Pleasanton, CA) after developing refractory cardiogenic shock. Because there was moderate aortic insufficiency (AI), the aortic valve was...
متن کاملHelical Flow Component of Left Ventricular Assist Devices (LVADs) Outflow Improves Aortic Hemodynamic States
BACKGROUND Although LVADs are confirmed to have strong effects on aortic hemodynamics, the precise mechanisms of the helical flow component of LVAD outflow are still unclear. MATERIAL AND METHODS To clarify these effects, 3 cases - normal case, flat flow case, and realistic flow case - were designed and studied by using the CFD approach. The normal case denoted the normal aorta without LVAD sup...
