The Midwest Adult Congenital Cardiac (MACC) Center
90 percent of children born with heart defects are now expected to live to adulthood and beyond. Thanks to advances in surgical and medical care, most people born with serious congenital heart defects are now surviving into adulthood.  The number of adults with congenital heart disease is increasing at a rate of 5% per year, and it is estimated that adults with congenital heart disease now outnumber children.  Unfortunately, many adults with congenital heart disease perceive their condition as “fixed” after surgical repair, believing they require no further follow-up care. This perception can potentially result in long-term health consequences.

To address the needs of adult congenital heart disease patients, Children’s Hospitals and Clinics of Minnesota has joined Children’s Heart Clinic and Minneapolis Heart Institute® to form the Midwest Adult Congenital Cardiac (MACC) Center. At the MACC Center, patients will experience a smooth, uninterrupted transition of healthcare from pediatric specialists to a medical team capable of providing comprehensive cardiac care, helping these individuals to live longer, healthier lives. Our medical professionals address important issues including:
 • Personalized education related to the individual’s specific condition
 • Potential interventions/surgeries needed in the future
 • Endocarditis prophylaxis
 • Heart-healthy diets
 • Exercise options
 • Emotional support
 • Appropriate family planning based on the individual’s unique physiology
 • Genetic counseling and high risk pregnancy care

With the MACC Center’s combination of specialized care providers, associated hospitals, and the ability to share advanced technologies, we are able offer a full range of outpatient and inpatient care including clinic appointments, advanced cardiac imaging, cardiac catheterizations, EP studies, surgical repair, coordinated high risk obstetric care for women with adult congenital heart disease and more.

Convenient, coordinated care

The Midwest Adult Congenital Cardiac (MACC) Center, a collaboration between Children's Hospitals and Clinics of Minnesota (CHCM), Children's Heart Clinic (CHC) and Minneapolis Heart Institute® at Abbott Northwestern Hospital, offers a patient-centered approach to health and healing. Our convenient locations and specialized staff allow us to provide the care and services you need, when you need it.



The MACC Center's Transition Clinic helps adolescent patients move from pediatric to adult-focused health care. We make the process easy for the patient and family by providing personalized guidance and follow-up. The partnering institutions of the MACC Center strive to provide the best care for each individual as they move from childhood to adulthood.


Advanced imaging technology is combined with the expertise of a pediatric cardiologist to help physicians plan treatment for adult patients with congenital heart defects.

Access to a cardiac CT and cardiac MRI represents an important aspect of the collaborative effort to care for adult CHD patients. The advanced imaging technology allows for substantially lower radiation exposure and eliminates the need for intubation of patients.

The MACC Center also performs echocardiograms and exercise testing to help diagnose and treat ACHD patients.

Heart Rhythm

The MACC Center is staffed by physicians who have subspecialty training in managment of heart rhythms. The heart rhythm specialists will determine the best care plan and have access to the latest technology to provide successful and safe ablations. They also provide medical management for patients with complex arrhythmias, and the program offers monitoring and follow-up services througout the state for patients with implantable devices.

Cardiac Catheterization/Interventional

The cardiovascular catheterization laboratory offers a variety of leading interventional treatments. Interventional cardiac catheterization is a non-surgical procedure that is increasingly used in diagnosing and treating congenital heart disease.

While non-invasive imaging tests, such as echocardiograms, cardiac MRIs and cardia CTs are effective diagnostic tools, further testing may be required in order to better understand the problem. Cardiac catheterization allows the cardiologist to analyze the heart from within the structure itself. The catheter (a long, thin, flexible tube) is inserted into a blood vessel, usually through the groin or upper arm, where it is then guided to the heart. Once in the heart, the catheter can provide diagnostic information and deliver treatment devices.

Cardiovascular Surgery

Some congenital heart diseases require no treatment, while others can be repaired of improved with surgery. The nationally recognized team specializes in the diagnosis and surgical treatment of heart disease and offers the full spectrum of congenital heart disease services and treatments.

Heart Failure

Heart failure is one of the fastest growing health problems in the United States, with people of all ages experiencing its life-changing effects. In many cases, the right treatment can slow the progression of the disease and help those with heart failure live longer, more satisfying lives.

MACC Center brings together a team that specializes in heart failure and understands how to manage it. Our team works closely with each patient, the patient's primary care doctor and the patient's family. This coordinated approach focuses on the individual needs of each patient and family and helps them live with heart failure more comfortably and easily.

Pulmonary Hypertension

The Pulmonary Hypertension Program provides comprehensive assessment and management for all types of pulmonary hypertension. Our specialized team provides 24-hour care for outpatient and urgent inpatient support. This dedicated team of professionals is committed to providing exceptional care and in-depth assistance for all aspects of this unique disease process.

Treatment options range from FDA-approved oral, inhaled, injectable and continuous IV therapies to involvement in research protocols from the latest clinical trials.

The state-of-the-art imaging available at Children's can help diagnose your child's condition and define the best possible course of treatment. At Children's, you'll find:

A specialty in pediatric cardiac imaging.

Imaging expert and pediatric cardiologist, Kelly Gleason Han, MD, is one of a handful of cardiologists in the U.S. with a specialty in cardiac imaging, which involved a two-year, advanced imaging fellowship at Boston Children's Hospital/Harvard Medical School.

Pediatric-trained radiologists.

Children's radiologists work in concert with cardiologists and cardiothoracic surgeons to provide procedures. The high level of team training and experience means that children who receive MRIs and CT scans at Children's typically receive lower doses of radiation.

Cardiac catheterization procedures.

In some cases, it may be possible to diagnose and treat your child at the same time through procedures performed in Children's pediatric cardiac catheterization lab, the only one of its kind in the upper Midwest.

A special focus on preventing discomfort.

Team members at Children's focus proactively on preventing the discomfort or anxiety that can occur with some tests. This may involve sedation (for example, through Children's award-winning nitrous oxide program, the use of imagery and pain control techniques taught by child life specialists, or other services provided through the integrative medicine department.

Diagnostic and less invasive services include:
