The primary goal of this study is to improve our understanding of changes in skeletal muscle mass in the arms and the legs during a hospitalization for advanced HF. We plan to measure muscle thickness with an ultrasound machine in two locations on the body (the outer thigh and the upper arm muscle, of the dominant side) from the time a patient is first admitted to the ICU with HF as well as before and after any surgical HF therapies.

Heart failure is a harmful disease that is associated with high avoidable moribidity that can be treated with a cardiac resynchronization therapy device (CRT-D). Previous studies have shown links between CRT-D implants and reduced rates of morbidity in patients with heart failure with left bundle branch blockages (LBBB). However, there is limited amounts of evidence for the success of heart failure patients with non-LBBB. This prospective, multi-center study is looking at heart failure patients with non-LBBB that are implanted with CRT-D.
The purpose of this randomized study is to evaluate the safety and effectiveness of EVAHEART 2 Implantable Left Ventricular Assist System (EVA2 LVAS) by demonstrating non-inferiority to HeartMate 3 when used for the treatment of advanced, refractory, New York Heart Association Class IV heart failure.
