This study is looking for volunteers who are having the Heart Mate 3 (HM3) Left Ventricular Assist Device (LVAD) implanted for treatment of heart failure. The study will collect medical information and patient experiences who have received treatment with the HM3. The traditional method to implant the HM3 is an incision in the middle of the chest through the breastbone (also called the sternum). This study will collect data if you have the Heartmate 3 implanted using a less invasive approach. Study participants will attend 8 visits over the course of 6 months.
