Heart Failure
What is Heart Failure?
If you have been diagnosed with heart failure (HF) it means your heart is not pumping enough blood to meet the body’s needs.1 Heart failure is a common condition. It currently affects 7 million people in the United States and more than 10 million people in the European Union.2,3
When heart failure occurs fluid starts to build up in the heart. This increases pressure in the upper chamber of the heart - or left atrium. If not treated fluid can then build up in the lungs -making it hard to breathe and can eventually lead to hospital visits.
Common Symptoms for Patients with Heart Failure
Shortness of breath during activity or even at rest
Shortness of breath when lying flat (may need extra pillows)
Feeling very tired (fatigue)
Rapid weight gain (from fluid buildup)
Swelling in the legs or feet
Heart Failure with Reduced Ejection Fraction (HFrEF):
Heart Failure with reduced Ejection Fraction (HFrEF) is one of two main types of heart failure. About half of all heart failure patients have HFrEF.5 Patients with HFrEF may have been told their heart's pumping function is reduced - described as pumping strength (or ejection fraction) of 40% or less.
Treatments for HFrEF
Medication is the cornerstone of treatment for HFrEF6. Patients are often prescribed multiple medical therapies depending on their symptoms and ability to tolerate the medications. Beyond medication other treatments may include lifestyle changes and medical devices such as implantable pacemakers or defibrillators. Even when taking these conventional treatments, some patients may still experience symptoms, and hospitalizations due to heart failure.4
New Technology Brings New Hope
For patients with HFrEF*, who still experience symptoms or hospitalizations even with conventional treatments, the V-Wave Ventura Interatrial Shunt may be an option. The V-Wave Ventura Interatrial Shunt is a small, device that stays in the heart permanently. It creates a pathway (opening) to let a small amount of blood flow from the left atrium to the right atrium. It is designed to lower pressure on the left side of the heart. This may reduce fluid backup into the lungs and help patients out of the hospital.7
If you have questions about your symptoms or which treatments may be right for you, talk with your cardiologist or heart failure care team.
