Retrospective analysis of the psychologic effects of mechanical circulatory support.

There is an increasing need to evaluate the psychologic impact of circulatory support because of the growing use of mechanical assist devices. Twenty-seven people, 12 survivors of mechanical circulatory assistance and 15 family members, were surveyed; nonsurvivors' families were not surveyed. The 12 survivors (ages 18 to 66 years; mean, 43 years) had been supported with Pierce-Donachy ventricular assist devices (nine patients) and the Novacor left ventricular assist system (one patient). One patient received a centrifugal pump, and one was supported with extracorporeal membrane oxygenation (ECMO). Duration of support ranged from 8 hours to 90 days (mean, 23 days). Ten people surveyed were spouses of these patients, and five were parents of children who had been supported with ECMO. Three patients were supported longer than 3 weeks, and four patients were awake and ambulatory during support. Financial worries were not a concern for 80% of the parents but were a concern for 80% of the spouses. Eighteen percent of the patients believed they were treated as an experiment, whereas 40% of their spouses thought they were. None of the parents thought their child was treated as an experiment. Sixty-seven percent of the patients stated that they have returned to a normal life-style, and 75% feel they have a brighter outlook on life. Six patients have returned to work, two are retired, two are disabled, and two have physical capabilities to work but choose not to. Eighty-nine percent of all those surveyed would recommend an assist device to someone who needed one. Although these procedures are often associated with severe medical and psychologic complications, 74% of the patients would agree to a second implant.
