Between January 2004 and December 2005, out of 14 patients with decompensated heart failure who were treated with an INCOR left ventricular assist device (Berlin Heart AG, Berlin, Germany), 10 patients were kept on a long-term regime of low molecular weight heparin (LMWH) and antiplatelet therapy. The treatment objective was bridge-to-transplantation. All patients received LMWH in therapeutic doses according to body weight, in combination with daily aspirin 160 mg, clopidogrel 75 mg, and three times dipyridamole 75 mg. Effectiveness of the low molecular weight regime was monitored through measurement of antifactor Xa activity (base and peak levels). Antiplatelet therapy was monitored through weekly platelet function tests. Within this group of 10 patients, six patients successfully received transplants and four patients died, the latest death after 405 days of INCOR support. Causes of death were sepsis, intestinal hemorrhage, acute right ventricular failure, and one major stroke. Long-term management of INCOR assist devices using a combination of LMWH and antiplatelet therapy is feasible. This treatment strategy can serve as an alternative to oral anticoagulants.
