Abbott Northwestern Hospital

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 surgical and medical breakthroughs. The Midwest Adult Congenital Cardiac (MACC) Center, a collaboration between Minneapolis Heart Institute® at Abbott Northwestern Hospital, Children’s Heart Clinic (CHC) and Children’s Hospitals and Clinics of Minnesota (CHCM), was created to treat these adult and adolescent survivors.

The MACC Center utilizes an integrated team approach when treating each patient because we believe patient care must individualized and continuous. We do this by staffing physicians who specialize in treating adult congenital heart disease (CHD). Our team of physicians and state-of-the-art technology provides unmatched quality of care and expertise in the full spectrum of CHD. When choosing Midwest Adult Congenital Cardiac Center, you will receive coordinated care using the most technologically advanced diagnostic and therapeutic treatments available, provided by specialists who truly care.

The MACC Center team of cardiovascular specialists and clinicians offer a full range of cardiology services for treating adult congenital heart disease, including:

  • a multi-disciplinary team of physicians and clinicians who evaluate patients’ entire well-being,
  • outreach and education for adults as they transition from adolescence to adulthood and
  • participation in research to identify best practices for adult patients with congenital heart disease.

Convenient, coordinated care

The Midwest Adult Congenital Cardiac (MACC) Center, a collaboration between Minneapolis Heart Institute® at Abbott Northwestern Hospital, Children’s Heart Clinic and Children’s Hospitals and Clinics of Minnesota, 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.


At the Minneapolis Heart Institute®, 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 the cardiac CT and cardiac MRI at the Minneapolis Heart Institute® represents an important aspect of the collaborative effort to care for adult CHD patients. The advanced imaging technology at MHI 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 management 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 throughout the state for patients with implantable devices.

Cardiac catherization/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 cardiac 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 or 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.

My story: Matt Bowman

Matt Bowman

On August 10th, 2006 I experienced an episode of severe chest pain and difficulty breathing while running during a high school soccer captain’s practice; I was 17 years old at the time. I was transported by ambulance to a local hospital and over the next day and a half, I underwent numerous heart tests, including an EKG, ECHO, and an exercise stress test. The results of these tests did not reveal any abnormality with my heart and I felt confident that the doctors had checked me quite thoroughly. I regained confidence and tried my best to put the incident behind me.

Fast forward two years later and I experienced another episode on August 20th, 2008, but this one was much more serious. I collapsed on the soccer field during a pre-season scrimmage at Augsburg College. I regained consciousness after a couple minutes and was immediately transported to North Memorial Hospital. Over the next few days, I went through more heart tests and was seen by a cardiologist who referred me to the Minneapolis Heart Institute (as I was now an adult). After having a CT angiogram, a fairly new diagnostic technology, the doctors were able to identify the problem. I was diagnosed with an anomalous left main coronary artery. Although this was a rare congenital heart defect, it is the second most common cause of death in young athletes. It is also quite rare to survive this type of incident, with as many as 8 out of 10 people not surviving. I am extremely grateful for the Minneapolis Heart Institute having the technology available to detect this type of heart defect, and for the physician’s ability and expertise in finding the problem.

After the diagnosis, I underwent open-heart surgery (reimplantation of my left main coronary artery). The surgery went exceptionally well and, fortunately, I do not need follow-up care, other than the few check-ups and tests a few months after my surgery. The Minneapolis Heart Institute was literally able to save my life and correct a problem which most certainly considerably shortened my lifespan. I will never forget my experience at the Children’s Heart Clinic and the Minneapolis Heart Institute and the expert care I received.
