title: Left ventricular assist device patient selection: do risk scores help?
abstract: Mechanical circulatory support (MCS) and left ventricular assist device (LVAD) implantation is becoming increasingly utilized in the advanced heart failure (HF) population. Until further developments are made in this continually evolving field, the need for appropriate patient selection is fueled by our knowledge that the less sick do better. Due to the evolution of MCS technology, and the importance of patient selection to outcomes, risk scores and classification schemes have been developed to provide a structure for medical decision making. As clinical experience grows, technology improves, and further favorable clinical characteristics are identified, it is incumbent upon the HF community to continually hone these instruments. The magnitude of such tools cannot be understated when it comes to aiding in the informed consent and shared-decision making process for patients, families, and the healthcare team. Many risk models that have attempted to address which groups of patients will be successful focus on short term mortality and not long term survival or quality of life. The benefits and pitfalls of these models and their potential implications for patient selection and MCS therapy will be reviewed here.
