Background Patients with LVAD require continuous monitoring and care, and since Implanting Centers (ICs) are more experienced in managing LVAD patients than other healthcare facilities, the distance between patient residency and IC could negatively affect the outcomes. Methods Data of patients discharged after receiving an LVAD implantation between 2010 and 2021 collected from the MIRAMACS database were retrospectively analyzed. The population was divided into two groups: A (n = 175) and B (n = 141), according to the distance between patient residency and IC <= or >90 miles. The primary endpoint was freedom from Adverse Events (AEs), a composite outcome composed of death, cerebrovascular accident, hospital admission because of GI bleeding, infection, pump thrombosis, and right ventricular failure. Secondary endpoints were incidences of mortality and complications. All patients were followed-up regularly, according to participating center protocols. Results Baseline clinical characteristics and indications for LVAD did not differ between the two groups. The mean duration of support was 25.5 +/- 21 months for Group A and 25.7 +/- 20 months for Group B (p = 0.79). At 3 years, freedom from AEs was similar between Group A and Group B (p = 0.36), and there were no differences in rates of mortality and LVAD-related complications. Conclusions Distance from the IC does not represent a barrier to successful outcomes as long as regular and continuous follow-up is provided.

Abstract
Background Patients with LVAD require continuous monitoring and care, and since Implanting Centers (ICs) are more experienced in managing LVAD patients than other healthcare facilities, the distance between patient residency and IC could negatively affect the outcomes. Methods Data of patients discharged after receiving an LVAD implantation between 2010 and 2021 collected from the MIRAMACS database were retrospectively analyzed. The population was divided into two groups: A (n = 175) and B (n = 141), according to the distance between patient residency and IC <= or >90 miles. The primary endpoint was freedom from Adverse Events (AEs), a composite outcome composed of death, cerebrovascular accident, hospital admission because of GI bleeding, infection, pump thrombosis, and right ventricular failure. Secondary endpoints were incidences of mortality and complications. All patients were followed-up regularly, according to participating center protocols. Results Baseline clinical characteristics and indications for LVAD did not differ between the two groups. The mean duration of support was 25.5 +/- 21 months for Group A and 25.7 +/- 20 months for Group B (p = 0.79). At 3 years, freedom from AEs was similar between Group A and Group B (p = 0.36), and there were no differences in rates of mortality and LVAD-related complications. Conclusions Distance from the IC does not represent a barrier to successful outcomes as long as regular and continuous follow-up is provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
