Devices and methods for treating degenerative, congestive heart disease and related dysfunction are described. Passive and active cardiac support structures mitigate changes in ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities. Cardiac efficiency is improved by providing reinforcement that restores or maintains an elliptical ventricular shape and mimics the position and positive inotropic effects of helical wound myofibrils to provide active contraction of the ventricle in synchrony with the metabolically required cardiac pace or output. In addition, the cardiac support structures compensate or provide therapeutic treatment for congestive heart failure and/or reverse the remodeling that produces an enlarged heart. The structures may be implanted in target heart regions using less invasive surgical techniques, such as those involving port access or small incisions into the thoracic cavity.
