Brief Summary

The prognosis for heart failure patients is bleak for the advanced stages of the disease, with a reported 6-month mortality rate of almost 50% in patients treated with chronic inotropic therapy. As well as its very severe prognosis, heart failure is a costly disease. Heart transplantation remains the reference treatment for the terminal stage of the disease but although this is an effective therapy, it does engender ethical, social, economic and legal problems. It also requires irreproachable and costly logistics, immuno-suppressor treatment and a lifetime of follow-ups. In particular, the number of donors has been going down steadily for several years in most countries which offer a heart transplant programme and some patients cannot take advantage of being added to a waiting list for a graft (age, co-morbidities…). It is in this context that, alongside the medical treatments for cardiac insufficiency, other therapeutic strategies were developed, including resynchronization and long-term mechanical circulatory support. The progress made in resynchronization is at several levels: better understanding of the action mechanisms, the development and improvement of equipment specifically dedicated to resynchronization and prospective and randomized clinical trials which have scientifically validated this technique. Simultaneously, many studies were published evaluating long term support with mechanical circulatory support (MCS), excluding light devices, as a bridge to transplant or an alternative to a transplant. It is also recognized that mechanical circulatory support with a new generation of continuous flow assist device improved the quality of life and functional capacity, with a reduced risk of device failure and infrequent need for replacement. The "Achilles heel" of cardiac resynchronization remains the 20 to 40% of patients who respond barely or not at all. Among this population of patients, some are not candidates for a transplantation and long-term mechanical circulatory support by axial pump is an alternative to be considered. We elaborated an original randomized pilot study for these patients in order to evaluate their survival and their quality of life, to define if they should be proposed a left ventricular assist device (LVAD)or not.
