Resumo

Gastrointestinal bleeding (GIB), a highly morbid adverse event of continuous-flow left ventricular assist systems (CF-LVASs), is thought to occur due to low-pulsatile blood flow in such circulatory systems and is a principal hemocompatibility-related adverse outcome.1,2 The reasons for development of GIB are multifactorial and relate to the unique circulatory stress, pro-angiogenic factor expression, and the iatrogenic environment with the use of anti-coagulant and anti-platelet therapy. High shear stress imposed on circulating blood elements leads to loss of high-molecular-weight von Willebrand factor (vWF) multimers producing an acquired von Willebrand syndrome.
