What to Expect Before, During, and After PVC Ablation

1. What to Expect Before, During, and After PVC Ablation Premature Ventricular Contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). While occasional PVCs are often harmless, frequent or symptomatic PVCs can disrupt normal heart function and may require treatment. One of the most effective solutions for patients with persistent or troublesome PVCs is PVC ablation, a minimally invasive cardiac procedure aimed at eliminating the source of these abnormal electrical impulses. If you’ve been advised to consider PVC ablation, you might be wondering what the procedure involves and how to prepare. This article will walk you through what to expect before, during, and after PVC ablation, so you can feel more informed and confident in your care. Before PVC Ablation: Preparing for the Procedure 1. Initial Consultation and Evaluation Before the procedure is scheduled, your cardiologist or electrophysiologist will conduct a thorough evaluation. This may include an electrocardiogram (ECG), Holter monitor, echocardiogram, cardiac MRI, or a stress test to understand the nature and frequency of your PVCs. These tests help determine if you’re a suitable candidate for ablation and to pinpoint the location of the PVCs. 2. Medication Review and Instructions Leading up to the procedure, your doctor may instruct you to stop certain medications, particularly anti- arrhythmic drugs, a few days in advance. This ensures that the PVCs are not suppressed during the ablation, allowing the medical team to accurately detect and target them.

2. 3. Fasting and Hospital Admission You’ll likely be asked not to eat or drink anything for 6–8 hours before the procedure. You should also arrange transportation, as you won’t be able to drive yourself home afterward. Most patients are admitted to the hospital either on the morning of the procedure or the night before. During PVC Ablation: What Happens in the Procedure Room 1. Arrival and Setup Upon arrival, you’ll be prepped in a special procedure room called an electrophysiology (EP) lab. You’ll be hooked up to monitors that track your heart rhythm, oxygen level, and blood pressure. An IV line will be inserted for medications and fluids. 2. Sedation or Anesthesia While some ablations are done under conscious sedation, others may require general anesthesia, depending on your specific case and the hospital protocol. You’ll be made comfortable and pain-free during the procedure. 3. Catheter Insertion and Mapping The electrophysiologist will insert thin, flexible tubes called catheters into a vein—usually in the groin— and guide them to the heart using X-ray imaging. These catheters are equipped with electrodes that help map the electrical activity of the heart. Using this data, the physician identifies the exact spot in the ventricle where the PVCs are originating. This process is known as electroanatomic mapping, and it allows for precise localization of the problematic tissue. 4. Ablation Process Once the source of the PVCs is located, the physician applies radiofrequency energy (or sometimes cryo- energy) through the catheter tip to destroy the small area of heart tissue causing the abnormal beats. This ablation disrupts the errant electrical signals, effectively stopping the PVCs. The whole procedure typically lasts between 2 to 4 hours. In some complex cases, it might take longer. After PVC Ablation: Recovery and What Comes Next 1. Immediate Post-Procedure Care After the ablation is complete, the catheters are removed, and pressure is applied to the insertion site to prevent bleeding. You’ll be moved to a recovery area, where nurses will monitor your heart rhythm, vital signs, and groin site for a few hours. You may feel slightly drowsy or groggy from the sedation. Minor discomfort, bruising, or soreness at the catheter site is common but usually short-lived.

3. 2. Hospital Stay and Discharge Most patients go home the same day or after an overnight stay. Your care team will give you specific instructions about activity levels, medications, and follow-up appointments. You’ll be advised to avoid strenuous activity and heavy lifting for several days. 3. Resuming Normal Activities Most people can return to their normal routine within a week, although recovery time varies. You may be advised to avoid driving for a short period and to monitor for any signs of complications, such as chest pain, swelling, or bleeding at the catheter site. 4. Follow-Up and Monitoring Your cardiologist will schedule follow-up appointments to assess the success of the procedure. Sometimes, you may be asked to wear a Holter monitor again to evaluate your heart’s rhythm post- ablation. It’s normal to experience occasional PVCs during the healing period, but if the ablation was successful, you should notice a significant reduction in symptoms over time. If PVCs persist or recur, a second ablation might be considered in rare cases. Is PVC Ablation Effective? For patients with frequent or symptomatic PVCs, especially when other treatments fail, PVC ablation has a high success rate. Studies show that ablation can eliminate or significantly reduce PVCs in 80–90% of cases. The risk of complications is low, especially when the procedure is performed by an experienced electrophysiologist. Trusting the Right Experts Choosing the right facility and specialists plays a crucial role in the success of your PVC ablation. The Heart ae is known for offering expert electrophysiology services in the UAE, using advanced technology and a patient-centered approach to treat complex arrhythmias like PVCs.

4. Final Thoughts PVC ablation is a safe and effective solution for individuals dealing with bothersome or frequent premature ventricular contractions. Understanding what to expect before, during, and after the procedure can ease anxiety and prepare you for a smoother experience. By working closely with a skilled electrophysiologist, following your care instructions, and attending your follow-ups, you’ll be on a promising path toward better heart health and a symptom-free life.
