Physicians & Hospitals Partnering for Excellence in Cardiac Care

The Maine Heart Center is a nonprofit provider network throughout southern and central Maine dedicated to:

  • Optimizing quality performance and data exchange
  • Delivering affordable and value-based care
  • Enhancing patient and provider engagement

Convenient access to high quality care

We actively partner with MaineHealth Cardiovascular Service Line (CVSL) and MaineHealth ACO (MHACO) to support cardiovascular program development and clinical care improvements for our patients and MHC member hospitals. The Maine Heart Center was formed with a vision of developing a network where, through a collaborative effort involving hospitals, cardiologists, surgeons, anesthesiologists, and consulting specialists, cardiac services are provided at a high standard of quality and on a cost-effective basis. The services are bundled and offered to payers through a packaged price methodology.

Our Network of Services

The Maine Heart Center is a network of hospitals and doctors who share knowledge, programs and guidelines to promote medical advancements that improve patient lives.
