Indications
Cardiac ablation is recommended for individuals with specific types of abnormal heart rhythms (arrhythmias) that haven't responded well to medications or other treatments. Common indications include:
- Atrial Fibrillation (AFib): Atrial fibrillation is a rapid and irregular heartbeat originating in the heart's upper chambers (atria). Ablation may be considered to restore normal heart rhythm when medications are ineffective.
- Supraventricular Tachycardia (SVT): SVT refers to various rapid heart rhythms originating above the ventricles. Ablation can correct abnormal electrical pathways causing SVT.
- Ventricular Tachycardia (VT): Ventricular tachycardia is a rapid heartbeat originating in the heart's lower chambers (ventricles). Ablation may be used to treat certain types of VT.
- Atrioventricular Nodal Reentry Tachycardia (AVNRT): AVNRT is a common type of SVT that involves abnormal pathways within the heart's electrical system. Ablation can eliminate these pathways.
- Accessory Pathways: Some individuals have extra electrical pathways (accessory pathways) in the heart that can cause abnormal rhythms like Wolff-Parkinson-White syndrome. Ablation can remove these pathways.
- Ventricular Fibrillation Risk: In some cases, ablation may be considered to reduce the risk of ventricular fibrillation, a potentially life-threatening arrhythmia.
Steps involved in Cardiac Ablation
During a cardiac ablation procedure, several steps are taken to diagnose and treat abnormal heart rhythms, also known as arrhythmias. Here's an overview of what happens during a cardiac ablation:
- Patient Evaluation: Before the procedure, the patient's medical history, symptoms, and previous diagnostic tests (such as electrocardiograms and Holter monitoring) are reviewed to identify the specific arrhythmia.
- Anesthesia: Local anesthesia or mild sedation is administered to ensure the patient's comfort during the procedure.
- Catheter Insertion: Catheter (thin, flexible tube) is inserted through a blood vessel, typically in the groin area. It's threaded up to the heart under X-ray guidance.
- Mapping: Specialized mapping catheters with electrodes are used to record the heart's electrical activity and identify the precise location of abnormal electrical signals.
- Energy Application: Once the abnormal sites are located, the catheter's electrode emits energy (such as radiofrequency or cryotherapy) to create controlled scar tissue or lesions. This disrupts the faulty electrical pathways causing the arrhythmia.
- Monitoring and Testing: Throughout the procedure, the patient's heart rhythm is monitored to ensure that the ablation is successfully eliminating the abnormal signals.
- Verification: After each energy application, the medical team verifies whether the arrhythmia has been successfully corrected by observing changes in the heart's electrical patterns.
- Completion: Once the necessary ablations are performed and the heart's rhythm is restored to a more regular pattern, the catheters are removed.
- Recovery: After the procedure, the patient is closely monitored in a recovery area for a few hours to ensure stability. Most patients can go home on the same day.
- Follow-Up: Follow-up appointments are scheduled to monitor the patient's progress, assess the success of the procedure, and make any necessary adjustments to medications or further treatments.
Who will Treat for Cardiac Ablation Procedure
- Cardiac electrophysiologist:Cardiac ablation is a specialized procedure performed by a cardiac electrophysiologist. A cardiac electrophysiologist is a cardiologist who has undergone additional training and expertise in the field of electrophysiology, which focuses on the electrical activities of the heart and the diagnosis and treatment of arrhythmias. These highly trained medical professionals have extensive knowledge of the heart's electrical system, the various types of arrhythmias, and the techniques used in cardiac ablation procedures.
Preparing for Cardiac Ablation Surgery
Preparing for cardiac ablation surgery involves several important steps to ensure a safe and successful procedure. Here's a comprehensive guide on how to prepare:
