I am honored to be part of Cardiovascular Services at MaineHealth — an integrated network of hospitals, health care providers and specialists — built with patients’ needs at the very center. Our service line combines medical and surgical services (both inpatient and ambulatory care), along with research and education, under unified clinical and administrative leadership. Our intent is to highlight our strong performance as evidenced by the data presented clearly and transparently on the following pages. Our 2020 report highlights many of our treatment offerings and leading technologies in use across MaineHealth.

For example, MaineHealth aims to help people with heart failure have the best possible clinical outcomes and quality of life. To achieve this, our organizations and partners implemented a variety of evidence-based treatments across the MaineHealth system to provide care as close to home as possible. This approach helps patients better manage heart failure symptoms. As a result, they need to be hospitalized less often. Care settings include patients’ private homes, nursing care facilities, medical care offices, emergency departments and hospitals. Treatment options include evidence-based clinical pathways, supporting clinical decision tools, providing patients with clear and consistent plans of care and specialized care for patients with advanced disease.

To enable a more seamless transition across the care continuum, Cardiovascular Services activated our shared electronic health record, Epic’s Cupid application, in February 2020. The success of this complex implementation is the result of outstanding teamwork, project management and leadership across our hospitals and physician practices.

I invite you to collaborate and partner with us as we continue to strive to improve cardiovascular care, quality and patient access, while delivering the best health outcomes.

People with congenital heart disease need care throughout their lives. From infancy through adulthood, people with congenital heart issues are best served by specially trained clinicians who understand their complex and unique needs. Our program offers a full range of inpatient and outpatient clinical services — from diagnosis to surgical repair. 

We care for pediatric and adult patients with all forms of congenital heart conditions and pulmonary hypertension issues. In 2019, MaineHealth launched a new program for adult patients with any form of congenital heart condition. This includes those with newly diagnosed congenital heart defects, as well as those with complex congenital heart disease who may have received care since childhood and now may require transition to adult medical services such as family planning, genetic counseling and ongoing cardiology care.
