Understanding AFib and When You Should Seek Intervention

Atrial fibrillation, or AFib, is a common heart rhythm disorder affecting millions of people worldwide. It occurs when the heart's upper chambers — known as the atria — beat irregularly, disrupting the normal flow of blood. This irregularity can increase the risk of blood clots, stroke and heart failure.

The Bayhealth Heart & Vascular Institute is focusing on raising awareness about AFib and the treatments available, including the advanced Left Atrial Appendage Occlusion (LAAO) procedure.

What is AFib?

AFib is a condition where the heart's rhythm becomes erratic and fast, often causing a feeling of palpitations, dizziness or shortness of breath. The disorganized electrical signals in the atria lead to a rapid and irregular heartbeat, which can compromise the heart’s ability to pump blood effectively.

Causes and Symptoms of AFib

Several factors can contribute to the development of AFib. These include high blood pressure, heart disease, diabetes, excessive alcohol consumption, undiagnosed sleep apnea and even stress. Genetics may also play a role in a person’s risk of developing AFib.

Common symptoms of AFib include a racing heartbeat, fatigue, shortness of breath, dizziness or chest pain. However, some individuals with AFib may not experience any symptoms at all, making it important to monitor your heart health regularly.

If you notice symptoms such as palpitations, dizziness or unexplained fatigue, it’s important to consult a healthcare provider. Early diagnosis and management can help reduce the risk of complications, including stroke.

The Benefits of LAAO Devices

In some cases, lifestyle changes or medication are enough to manage AFib. However, when these approaches are not effective, surgical intervention may be necessary. One of the most advanced treatments for AFib is the LAAO procedure, also commonly referred to as the Watchman or Amulet procedure. This procedure involves closing off the left atrial appendage, the area of the heart most associated with blood clots in AFib patients. By reducing the risk of stroke, LAAO helps improve the quality of life for those with persistent or high-risk AFib.

Bayhealth offers a variety of LAAO devices. These are minimally invasive and offer patients a safer, long-term alternative to blood thinners. They are FDA-approved for use in AFib patients who are not candidates for long-term blood thinners due to factors such as lifestyle, noncompliance, or other medical reasons.

Devices, such as Watchman or Amulet, are implanted through a small catheter, reducing recovery time and minimizing the risks associated with traditional surgery. Patients who receive these devices typically experience fewer complications related to stroke and improved peace of mind.

Bayhealth Cardiologist Manjeet Singh, DO, FACC, emphasizes the importance of choosing the right treatment for each patient. "The Watchman and Amulet devices offer our patients a proven, minimally invasive solution that significantly reduces the risk of stroke associated with AFib," said Dr. Singh. "For patients who cannot tolerate blood thinners, these devices can be life changing."

For those struggling with AFib, Bayhealth Heart & Vascular Institute offers comprehensive care, from diagnosis to advanced intervention. If you think you may be at risk for AFib or are experiencing symptoms, don’t wait to get checked. Timely intervention can improve your heart health and overall well-being.
