To the Editor: The study of long-term outcomes and costs of ventricular assist devices by Dr Hernandez and colleagues1 provided some interesting data, but because of the large amount of progress in this field over the past 2 years, it is of mostly historical value for comparisons with current outcomes with these devices. Also, the observations are too broad because of the inclusion of patients with multiple device indications, various devices used for diverse indications, and unknown indications for readmissions.
