At the Mitral Valve Repair Center at Johns Hopkins Hospital, our team, led by James S. Gammie, M.D., excels in advanced valve operations, including mitral valve repairs. Dr. Gammie directs a high-volume program, with more than 300 mitral valve procedures performed annually, including multivalve operations.
Our collaborative approach ensures exceptional outcomes, with a repair rate exceeding 99% for degenerative mitral valve regurgitation and 89% across all mitral valve disease etiologies. Our safety record surpasses national averages, and long-term outcomes are among the world’s best.
The Johns Hopkins Hospital has received the Mitral Valve Repair Reference Center Recognition Award, which recognizes centers in the United States with a demonstrated record of superior clinical outcomes in degenerative mitral valve repair resulting from evidence-based guideline treatment. Johns Hopkins is one of fewer than 25 Mitral Valve Repair Reference Centers in the U.S. that have earned this distinction.
Skilled surgeons specializing in mitral valve repair can successfully fix 95-100% of degenerative valves, regardless of the cause. However, in the broader cardiac surgery field, only about 70% of valves are repaired. Barlow’s valves, which have more complex issues, need advanced techniques for repair.
Our team has expertise in all types of mitral valve disease and provides comprehensive repair and replacement for all patients.
What Is Mitral Valve Disease?
Mitral valve disease has two types: mitral valve regurgitation and mitral valve stenosis. Both conditions strain the heart and can lead to severe symptoms like arrhythmia, heart failure and permanent damage if not treated.
Mitral Valve Regurgitation
Mitral Valve Stenosis
Other Common Conditions That May Accompany Mitral Valve Disease
Atrial fibrillation: Atrial fibrillation (AFib) is a heart rhythm disorder marked by rapid and irregular electrical activity in the upper heart chambers, or atria. This irregular heartbeat can cause symptoms and increase the risk of complications like stroke and heart failure. Treatment involves medications and interventions to control heart rate and rhythm and reduce complications.
Tricuspid valve regurgitation: Tricuspid valve regurgitation occurs when the tricuspid valve fails to close properly, leading to the backflow of blood from the right ventricle into the right atrium during the heart’s contraction.
Medical team members at Johns Hopkins are also experts in treating these diseases.
