What are the main findings? Response: The MOMENTUM 3 trial is the largest study of LVAD therapy in Advanced Heart Failure with over 1000 randomized patients followed to at least 2 years. This trial tested a novel fully magnetically levitated LVAD, the HeartMate 3 pump against a mechanical bearing containing LVAD, the HeartMate II pump in patients suffering from advanced heart failure (85% of whom were on continuous intravenous Inotropic therapy or IABP device at the time of randomization). While LVADs have improved survival for such patients, the morbidity has remained excessive due to serious complication as a result of problems with hemocompatibility. The principal concerns revolve around complications of pump thrombosis requiring surgical replacement, strokes and bleeding events, especially gastrointestinal bleeding. The trial has previously reported two interim analyses which suggested signals for superiority on pump replacement and even a decrease in ischemic stroke. This final full report concludes convincingly that all three domains of hemocompatibility related adverse events are reduced with the novel LVAD with near elimination of pump thrombosis, halving of strokes of any kind and any severity and a marked decrease in bleeding complications.
