A multidisciplinary evaluation of ECMO patients done by intensivists, cardiologists, and surgeons may influence weaning and survival rate. Our approach seems to be a safe and reproducible strategy for avoiding left ventricle distension and fluid overload, and for detecting complications that negatively affect outcomes.
Left ventricular assist device thrombosis is a detrimental complication that, if not properly diagnosed and treated, can lead to low output syndrome and death. When ongoing thrombus formation is caused by inappropriate anticoagulation, timely identification is possible, and could perhaps be the key to successful treatment.
The aim of this study was to test the impact of donor and recipient characteristics on the development of primary graft failure (PGF) after heart transplantation (HT) by focusing on the donor's inotropic support. Heart donors and matched recipients data were prospectively collected. Univariate and multivariate analyses were used to determine independent predictors for PGF and peri-operative mortality. The donor's high inotrope requirement was defined as sustained need for dopamine exceeding 10 microg/kg/min and/or alpha agonists exceeding 0.06 microg/kg/min. PGF instead was defined as need for immediate post-HT mechanical circulatory support. Since 2006, we have performed 37 HTs. PGF occurred in six patients (16.2%). Although four patients (66.6%) were weaned off circulatory support, two of them (33.3%) died on mechanical assistance. Total in-hospital mortality was 10.8% (4/37). Upon multivariate analysis, pre-harvesting donor high inotrope dosage was the major determinant for PGF (P=0.03, OR=10.8). Given the organ shortage, many centers accepted marginal hearts assuming the donor's pre-harvest hemodynamic managing has a reduced impact on PGF development. As PGF remains the most lethal postoperative complication, the hazards should be carefully considered when using pre-harvesting high inotrope infusion rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
