Coagulation and Complications of Left Ventricular Assist Device Therapy

Abstract

Implantation of left ventricular assist devices (LVADs) is becoming more common with the advancement of mechanical circulatory support technology and the continued insufficient number of organ donors available for heart transplantation. Modern LVADs provide a mechanically induced, nonpulsatile, continuous blood flow that drastically alters the hemodynamic and coagulation profile of patients using these devices. In addition to the risk of bleeding and thrombotic events, LVAD support can also lead to arrhythmias and infection. Although LVAD therapy can prolong life, the majority of patients will experience an adverse event following implantation and many of these complications can result in emergency department visits. By understanding the pathophysiology and management of LVAD complications, emergency nurses will be able to provide prompt and quality care for this unique patient population.

“…Također, važnosti praćenja nalaza koagulacije (PV/INR), antikoagulatnoj terapiji, praćenje balansa tekućine, aktivnostima u svakodnevnom životu. 2 Zdravstvena njega bolesnika sa LVAD-om predstavlja izazov. Savjetodavna uloga medicinske sestre, individualni pristup te senzilibitet za potencijalne probleme čini nas sponom između cjelokupnog medicinskog tima i pacijenta i njegove obitelji.…”

“…Another unavoidable issue is the unceasing necessity of anticoagulant therapy (avoiding ischemic events) as well as regular coagulation and volume monitoring. 2 Patients healthcare, after implantation of a cardiac assist device, is nowadays still a challenging venture. The advisory role of the nurse an individual approach and sensibility for noticing and preventing potential risks makes the nurse a link between the entire medical team, the patient and his family.…”
