Abstract
There has been an intense and competitive quest to manufacture bioartificial heart muscle in the last decade. Numerous biocompatible scaffolds and scaffold-free systems, enriched with various cell types, have been used to fabricate 3D grafts for myocardial repair. In spite of the impressive achievements in the myocardial tissue-engineering field, many issues remain to be addressed before clinical application of this strategy becomes feasible. This is largely due to the uniqueness of the heart s structure and function. This review provides a survey upon the reported strategies, and indicates caveats and perspectives in the field of myocardial tissue engineering.
