At PromiseCare Medical Group in Hemet, California, patients with supraventricular tachycardia (SVT) have access to a minimally invasive treatment option that targets the root cause of the condition: SVT ablation.
According to data from our medical group, this procedure boasts a high success rate of 90-95% in improving the quality of life for individuals with SVT.
Our cardiologists use radiofrequency energy or cryoablation to create scars in the heart tissue that disrupt the abnormal electrical signals, restoring a normal heart rhythm.
As patients consider this treatment, it’s essential to understand what to expect, from preparation to results, and the benefits that await them under our experienced medical team.
Overview
Managing supraventricular tachycardia (SVT), a type of abnormal heart rhythm, can be complex.
An SVT ablation procedure is a potential solution targeting irregular heart rhythms’ root cause. This procedure uses radiofrequency energy or cryoablation to create small scars in the heart tissue, effectively blocking the faulty electrical signals that trigger SVT episodes.
The procedure typically lasts 3 to 6 hours and is performed in a hospital setting, often requiring an overnight stay for recovery.
Success rates are between 90% and 95%, and the rapid heartbeat recurrence rate following the procedure is relatively low.
SVT ablation is a viable option for those seeking to regain control over their heart rhythms and improve their overall quality of life, especially when medication is ineffective or causes undesirable side effects.
Types
To effectively target the underlying cause of supraventricular tachycardia, one must comprehend the various types of arrhythmias eligible for SVT ablation. Rapid heartbeats can stem from different forms of tachycardia, such as atrial flutter and atrial tachycardia. These arrhythmias arise in the heart’s upper chambers, accelerating pumping.
SVT ablation can effectively treat specific forms of SVT, such as atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT), including Wolff-Parkinson-White syndrome.
During SVT ablation, a catheter is inserted into the heart, emitting energy to disrupt the abnormal electrical signals causing tachycardia. Methods such as cryoablation, which uses extreme cold, and radiofrequency energy, which applies heat, can be employed.
Ablation can also provide a long-term solution for children at high risk of heart-related complications from SVT. While SVT ablation doesn’t directly target atrial fibrillation, it can treat underlying conditions that may lead to this more complex arrhythmia.
Why it’s done
Supraventricular tachycardia is a condition in which the heart’s electrical system malfunctions, causing a rapid and erratic heartbeat. When this happens, the heart’s rhythm becomes disrupted, leading to breathlessness and disorientation.
In such cases, a procedure called SVT ablation may be recommended to restore the heart’s normal electrical function. This procedure treats conditions that cause fast, erratic heartbeats, such as atrial flutter, atrial tachycardia, and Wolff-Parkinson-White syndrome.
If medications have failed or are causing more harm than good, ablation can be a viable treatment option. The goal of the procedure is to target and eliminate the abnormal heart cells that disrupt standard electrical signals, effectively interrupting the short circuits responsible for the irregular heart rhythm.
Eliminating these rogue cells restores the heart’s natural rhythm, freeing the individual from the symptoms of SVT. Success rates for SVT ablation range from 90% to 95%, making it a promising solution for heart rhythm problems that don’t respond to medication.
Who it’s for
Someone struggling with the unpredictable rhythms of supraventricular tachycardia may wonder if SVT ablation is the right solution. The racing heartbeat and crushing fatigue that can strike at any moment, disrupting life and leaving one feeling helpless, are likely familiar experiences. If medications haven’t provided relief or have resulted in unbearable side effects, contemplating SVT ablation is a reasonable next step.
This procedure targets the faulty electrical signals that trigger fast heartbeats and is used to treat conditions like atrial flutter, atrial tachycardia, AVNRT, and AVRT, including Wolff-Parkinson-White syndrome.
Parents may worry about their child’s risk of heart-related complications from SVT; ablation can be a lifesaver in these cases. Ultimately, SVT ablation is for anyone whose quality of life has been significantly impacted by recurrent symptoms and for whom other treatment options have failed.
Risks
Medical procedures almost always involve risk, and SVT ablation is no different. When contemplating the benefits of this procedure, it’s essential to consider the potential risks and complications. Although the likelihood of serious complications like stroke, heart attack, or death is under 1%, recognizing these possibilities is vital.
Additional side effects, such as bleeding or infection, can occur at the catheter insertion site, potentially necessitating further medical care. Furthermore, there is a chance of SVT recurrence, reported in 2% to 11% of patients, varying based on individual factors and the procedure’s success.
In rare cases, the procedure may damage the heart’s conduction system, necessitating a pacemaker, a likelihood of less than 1%. Furthermore, there’s a small risk of puncturing the heart or damaging surrounding organs, which may require surgical intervention.
It’s essential to carefully weigh these risks against the benefits of SVT ablation, ensuring an informed decision about heart health. One can better navigate this procedure and its outcomes by understanding the potential risks and complications.
How you prepare
Preparation for SVT ablation starts 24 hours before the procedure. Dietary guidelines include specific food and drink restrictions. Additionally, fasting for 6 to 8 hours before the procedure is required to maintain a clear stomach for anesthesia.
It’s crucial, as anesthesia is administered to ensure comfort during the procedure, and a catheter is inserted.
All medications must be disclosed in the days before the procedure, as some may need to be paused to avoid complications. Any underlying health conditions or concerns should also be discussed to guarantee a safe and effective ablation process.
Jewelry should be left at home, and transportation should be arranged after the procedure, as sedation may be used.
What you can expect
SVT ablation is a 3 to 6 hour procedure performed in a hospital. Its goal is to restore the heart’s normal rhythm. Sedation is administered to keep the patient calm and relaxed throughout the procedure.
The procedure involves the following steps:
- Insertion of the catheter: A small incision is made in the groin, and the catheter is guided to the heart.
- Mapping the heart’s electrical activity: The catheter records the heart’s electrical signals, pinpointing the source of the tachycardia.
- Applying radiofrequency energy: The catheter applies radiofrequency energy to destroy the abnormal heart cells.
- Monitoring and recovery: The medical team monitors the heart’s activity to ensure the procedure is successful and the patient begins the recovery period.
After the procedure, the patient typically stays overnight in the hospital. The medical team closely monitors the heart rhythm to ensure the SVT ablation successfully restores the heart’s normal rhythm.
Results
SVT ablation typically yields impressive results, with most patients experiencing a significant improvement in their quality of life. Success rates range from 90% to 95% in eliminating symptoms, allowing patients to return to normal activities soon after recovery.
The recurrence of supraventricular tachycardia after SVT ablation is relatively low, occurring in approximately 2% to 11% of patients; this indicates a generally favorable long-term outcome, with most patients enjoying a life free from the burden of SVT symptoms.
However, follow-up care is vital, as some patients may require repeat procedures if symptoms return post-ablation. While the procedure is highly effective, there are potential side effects, including bleeding, infection, and, in rare cases, the need for a pacemaker due to conduction system damage.
Despite these risks, the long-term prognosis is generally favorable with successful ablation. Successful ablation allows patients to regain control of their lives and enjoy a better quality of life. Understanding the potential outcomes can help inform treatment decisions and lead to a life free from SVT symptoms.
