An overview of AV node ablation
AV node ablation is a medical procedure used to treat atrial fibrillation, an irregularly fast and disorganized heartbeat. The procedure involves the use of heat (radiofrequency) energy to destroy a small amount of tissue between the upper and lower chambers of the heart (AV node). This disrupts the electrical signaling connection that causes atrial fibrillation.
What is AV node ablation used for?
An AV node ablation is a treatment for atrial fibrillation, an irregularly fast and disorganized heartbeat. During the procedure, a small amount of tissue between the upper and lower chambers of the heart (AV node) is destroyed using heat (radiofrequency) energy. As a result, a permanent pacemaker is implanted to control the heart rhythm. AV node ablation is generally considered the last option because it requires the placement of a pacemaker.
How to prepare for AV node ablation?
Before an AV node ablation, your health care provider will order several tests to check your heart health. They will also provide instructions on how to prepare for the procedure and what to bring to the hospital. Patient preparations may include:
- Stopping certain medications: You may be instructed to stop taking certain medications before the procedure, such as blood thinners or antiplatelet drugs.
- Fasting: You may need to fast for a certain period before the procedure, typically overnight. This is to ensure that your stomach is empty, reducing the risk of complications during the procedure.
- Refraining from smoking: You may be asked to avoid smoking before and after the procedure, as smoking can increase the risk of complications.
- Showering with an antiseptic solution: You may be advised to shower with an antiseptic solution the day of the procedure to reduce the risk of infection.
- Bringing necessary items: Make sure to bring any necessary items, such as your ID, insurance card, and a list of your current medications. It is crucial to follow your health care provider's specific instructions regarding preparations, as they will be tailored to your individual needs and medical history.
How is AV node ablation conducted?
AV node ablation is a medical procedure to treat irregularly fast and disorganized heartbeats, such as atrial fibrillation. The test is performed in a hospital, and the doctor inserts a catheter through a blood vessel, usually in the groin, and into the heart. Sensors on the tip of the catheter apply heat (radiofrequency energy) to the heart tissue at the AV node and destroy the electrical signaling connection. Once the AV node is destroyed, a pacemaker is implanted to control the heart rhythm.
How are AV node ablation results reported?
After AV node ablation, your symptoms and quality of life will likely improve. You will also need a permanent pacemaker to control your heart rate, and may need to take blood thinners to reduce your risk of a stroke. Please consult with your healthcare provider for more detailed information about the results and reporting of your specific AV node ablation procedure.
Understanding the report
AV node ablation is a treatment for atrial fibrillation that uses heat energy to destroy a small amount of tissue between the upper and lower chambers of the heart. After the procedure, a permanent pacemaker is necessary for proper heart function. AV node ablation is generally considered the last option because it requires the placement of a pacemaker. Results after AV node ablation may improve symptoms and quality of life, but you will need to take blood thinners to reduce your risk of a stroke.
