Valve Science Center
Heart valve disease is a preventable public health crisis. Our world-class research and education center is leading the way to providing life-saving solutions for you.
Solving a public health crisis.
More than 5 million Americans are diagnosed with heart valve disease every year, which can cause heart attacks, arrhythmia, congestive heart failure and other heart disease — significantly impacting quality of life and even leading to death. The good news is that most valve disease can be successfully treated in patients of all ages.
Our Valve Science Center leads the industry in minimally invasive, non-surgical valve repair and replacement. We are improving outcomes for patients with heart valve disease.
Under the leadership of Dr. Paul Sorajja, MHIF’s Valve Science Center is a national leader in the transcatheter treatment of aortic and mitral valve disease. MHIF is integrated with a high-quality, high-volume cardiovascular care center at Abbott Northwestern Hospital (ANW), which allows us to study and offer cutting-edge treatment to a large number of patients with valve disease.
Dan was involved in a cardiovascular research study at the Minneapolis Heart Institute Foundation, when he was surprised to learn he had valve disease. Listen to Dan’s story, and hear from his physician, Dr. Mario Gössl, and MHIF CEO, Kristine Fortman, PhD, about valve disease and how research has led to less invasive treatments.

On Feb. 20, 195 people attended our educational event, The Mechanics of a Healthy Heart, at Minnesota Valley Country Club to learn more about heart valve disease and the latest treatments from our renowned physician researcher partners at Minneapolis Heart Institute®.
MHIF established the Valve Science Center to improve outcomes for patients with heart valve disease. The center will allow researchers to:
• Study and gain insight into the barriers to care for under-treated populations of heart valve disease patients.
• Design, develop and implement novel guideline-based patient care pathways.
• Expand the delivery of high-quality, state-of-the-art care for heart valve patients.
• Educate the public on the needs of this patient population and opportunities for improvement in care.

Through these apps, physicians access data and clinical insights to determine the technology options based on their individual patient needs, including guidance and insights on the implant procedure. Notably, the apps are free to download and are updated every year to provide up-to-date guidance.
