Cardiac Ablation Procedures

Advanced catheter ablation for AF, SVT, VT and ectopic beats

What is catheter ablation?

Catheter ablation is a minimally invasive procedure used to treat heart rhythm disorders. Thin flexible catheters are passed into the heart via the veins, allowing the source of the arrhythmia to be precisely mapped and treated with energy — most commonly radiofrequency, cryotherapy or pulsed-field energy.

Restore normal rhythm

Eliminate or significantly reduce arrhythmia episodes.

Reduce medication

Many patients are able to stop or reduce antiarrhythmic medications.

Day-case procedure

Most patients are discharged the same day or after one night.

High success rates

Particularly high success rates for SVT and typical atrial flutter.

Procedure overview

Pre-procedure assessment and detailed consent

Sedation or general anaesthesia depending on procedure

Catheters inserted via the femoral vein under local anaesthetic

Electrical mapping of the heart with advanced 3D systems

Targeted ablation of abnormal tissue

Recovery in the day-case unit or overnight stay

Recovery

Most patients return home within 24 hours. Light activity is recommended for 1–2 weeks, with a return to normal activity shortly after. A follow-up review is arranged at 6–12 weeks.

Success rates & risks

Success rates depend on the arrhythmia treated. SVT and typical flutter ablation are typically >95% successful. AF ablation success rates range 70–85% depending on AF type — sometimes requiring more than one procedure.

Risks

•Vascular complications at the access site

•Bleeding or bruising

•Cardiac perforation (rare)

•Stroke (very rare, mitigated by anticoagulation)

•Need for repeat procedure in a minority of patients

Dr Creta will discuss the specific risks and benefits relevant to your case during your consultation.

Ablation procedures performed

AF Ablation

Pulmonary vein isolation for paroxysmal and persistent atrial fibrillation, using contemporary technologies including pulsed-field ablation.

SVT Ablation

Curative treatment for AVNRT, AVRT and atrial tachycardia — success rates typically above 95%.

VT Ablation

Ablation for ventricular tachycardia in patients with and without structural heart disease.

Ectopy Ablation

For symptomatic, frequent or high-burden ventricular ectopic beats.
