Abstract:
Skeletal muscle ventricles (SMV) were constructed from canine latissimus dorsi muscle and chronically stimulated to pump fluid within a totally implantable mock circulation device. They were stimulated to contract at either 95/min (N = 7) or 54/min (N = 4). The preload was chronically maintained at 20 mmHg. After 1 month of continuous pumping the SMV were capable of generating a stroke work of 0.134 X 10(6) ergs and power output of 0.021 watts, representing 61% and 42% of the stroke work and power output of the native canine right ventricle, respectively.
