Key result
Simple left heart assist device achieves ~68% weaning rate in refractory post-cardiotomy shock.
Why the study?
A simple left heart assist device was developed for patients with severe left ventricular dysfunction who could not be weaned from cardiopulmonary bypass after intracardiac surgery despite maximal therapy including IABC.
Does a simple left heart assist device improve survival and weaning from cardiopulmonary bypass in patients with severe left ventricular dysfunction?
Observational (n=19)

A simple left heart assist device can successfully rescue a subset of patients with severe LV dysfunction who cannot be weaned from cardiopulmonary bypass using conventional methods.
A simple left heart assist device (LHAD) has been developed and employed in nineteen patients with severe left ventricular dysfunction who could not be weaned from cardiopulmonary bypass following intracardiac surgery. It has been used when all other means of weaning, including maximum pharmacologic therapy and intra-aortic balloon counterpulsation (IABC), had failed. The device utilizes specially designed and constructed obturated cannulae in the left atrium and the ascending aorta, and an extracorporeal roller pump to partially bypass the left ventricle. With improved cardiac performance, the patient may be separated from the device without need for thoracic reentry. Of the nineteen patients having LHAD support (2-500 hours), thirteen were eventually weaned from the device and seven were discharged from the hospital. Five patients remain alive and well (18 to 50 months postoperatively).
