VT Ablation in Los Angeles
A detailed mapping and ablation procedure for ventricular tachycardia, guided by an electrophysiologist who stays with you through every decision and every follow-up.
Why people choose VT ablation
Repeated ICD shocks or pacing
Episodes of very fast heartbeat
Near-fainting or dizzy spells
Medicines with hard side effects
When VT keeps returning despite medicine or an ICD, ablation may reduce how often episodes happen.
Your physician guides every VT decision with you
VT care involves careful choices about medicine, devices and ablation. The electrophysiologist who explains those choices is the one who performs your procedure and reviews your device and rhythm afterward.
- Fellowship-trained in cardiac electrophysiology
- Coordination with your cardiologist and heart failure team
- Device and rhythm follow-up with the same physician
How VT ablation works
Planning and imaging
We review ECGs, device recordings and heart imaging to plan where VT may start.
Building a detailed map
Catheters map the heart muscle, often finding scarred areas that let VT circuits form.
Targeted ablation
Energy is applied to the channels and spots that keep the fast rhythm going.
Hospital recovery and follow-up
You are monitored closely in hospital, then reviewed by the same physician afterward.
VT ablation may be a good fit if
- VT returns despite rhythm medicines
- Your ICD has treated repeated episodes
- You have VT from a single focused spot
Other options we’ll discuss
Understanding VT ablation
What ventricular tachycardia is
Ventricular tachycardia (VT) is a fast rhythm that starts in the heart’s lower chambers, the ventricles. At very fast rates the heart has less time to fill, so it pumps less blood with each beat.
Short runs may cause few symptoms. Longer episodes can cause dizziness, chest discomfort or fainting, and some forms can lead to cardiac arrest. Call 911 if a fast heartbeat comes with fainting, chest pain or severe shortness of breath.
VT with and without heart disease
In many people, VT is linked to scar in the heart muscle. That scar may come from an earlier heart attack or from a cardiomyopathy. Electrical signals can travel through narrow channels in and around the scar, forming a loop that drives the fast rhythm.
Your physician may also look for problems that can make VT more likely, such as low potassium or magnesium, thyroid issues, reduced blood flow to the heart or worsening heart failure. Treating these can be an important part of the plan alongside any procedure.
Other people have VT in a heart that is otherwise structurally normal. This idiopathic VT often comes from one small spot, such as the outflow area where blood leaves the heart. It behaves differently and is usually approached in a more focused way.
How ablation fits with an ICD
Many people with scar-related VT already have an ICD. The ICD watches for dangerous rhythms and treats them, but it does not stop them from starting.
Ablation aims to make episodes less frequent, which may mean fewer device treatments and fewer shocks. For most people with scar-related VT, ablation is added to the ICD rather than replacing it.
Preparing for a VT ablation
Planning is a large part of VT care. Before the procedure your physician may order a cardiac MRI or CT scan to show where scar sits in the heart muscle. Your ICD recordings are also reviewed, because the shape and speed of past episodes help point to their source.
You may need blood tests, a review of your heart failure medicines and instructions about blood thinners and rhythm medicines. Talk to your physician before changing any medicine. Because VT ablation usually involves a hospital stay, plan for a family member or friend to help you at home for the first several days.
We also keep your general cardiologist informed, so everyone caring for your heart is working from the same plan.
What happens during the procedure
VT ablation is often a longer, more involved procedure than other ablations. It is usually done under general anesthesia or deep sedation. Catheters reach the heart through blood vessels in the leg, and sometimes the left ventricle is reached by crossing from the right side of the heart.
Your electrophysiologist builds a detailed 3D map of the heart muscle. Depending on your rhythm, mapping may be done during VT or in normal rhythm by looking for scar and abnormal signals. In some cases the circuit lies on the outer surface of the heart and needs a different approach. Your physician will explain if this applies to you.
Recovery
Most people stay in hospital for at least one night, and sometimes longer, with continuous heart monitoring. Your device may be checked and adjusted before you leave.
At home, expect tiredness for a week or more. Your physician will tell you when you can drive and return to activity, and will review your rhythm medicines and device recordings at follow-up. Talk to your physician before changing any medicine.
Risks
VT ablation carries more risk than many other ablations, partly because many patients already have a weakened heart. Possible complications include bleeding, damage to the heart or blood vessels, stroke and worsening heart failure. Your physician will weigh these against the risks of ongoing VT and talk them through with you and your family.
Questions about VT ablation
Will I still need my ICD after VT ablation?
Most people with scar-related VT keep their ICD after ablation. The ICD remains a safety net in case a dangerous rhythm returns. Your physician will explain how ablation and the device work together in your case.
How long is the hospital stay?
Many people stay one night or a few nights, depending on their heart function and how the procedure went. People with idiopathic VT and a structurally normal heart may sometimes go home sooner. Your care team will plan this with you.
Can VT come back after ablation?
Yes, VT can return, especially when it is related to scar, and some people need more than one procedure. Even so, ablation may reduce how often episodes happen. Ongoing device and rhythm checks help catch any recurrence early.
Is VT ablation an emergency procedure?
Sometimes it is done urgently for frequent episodes that are hard to control, often called an electrical storm. More often it is planned ahead after a careful review of your history. If you have repeated shocks or feel unwell, call 911.
Who decides whether I need VT ablation?
You decide together with your electrophysiologist, often with input from your general cardiologist or heart failure team. The decision depends on your type of VT, your heart function and how well other treatments are working. Our questions to ask your electrophysiologist guide can help you prepare.
