This study is testing a device called a Coronary Sinus Reducer in patients with a specific type of heart failure where the heart's pumping strength is preserved, but tiny blood vessels in the heart aren't working well. Researchers want to see if implanting this device can improve blood flow to the heart muscle and reduce symptoms like shortness of breath and chest discomfort.
Some people have heart failure even though their heart's main pumping chamber works normally, but their tiny blood vessels don't deliver enough oxygen-rich blood. This treatment is being studied to see if it can help these patients feel better and reduce their symptoms when other treatments haven't fully worked.

As a participant, you would undergo the procedure to have the Coronary Sinus Reducer device implanted in your heart. After implantation, you'll have follow-up visits where doctors use imaging tests (including heart scans called cardiac magnetic resonance) to measure whether the device is improving blood flow to your heart muscle and reducing your symptoms.
