[Cardiac assistance using transformed striated skeletal muscle: cardiomyoplasty]

The biomechanical potential of transformed skeletal muscle used for cardiocirculatory assistance is the keystone of this surgical concept. This underscores the necessity to modulate type II to type I transformation to premise the muscle bulk, shortening velocity, and, therefore, power. It is only if an efficient autologous engine is available that optimal surgical configuration (i.e. aortomyoplasty) will provide active cardiocirculatory support.
