Atrial Fibrillation Ablation

Atrial Fibrillation Ablation represents a cutting-edge treatment strategy for an irregular and often rapid heart rate condition known as Atrial Fibrillation (AFib). The procedure utilises heat or cold energy to generate small scars in the left upper chamber of the heart, effectively disrupting the errant electrical signals and restoring a regular heartbeat.

This procedure becomes a vital treatment choice when medications or other therapies fail to manage the condition effectively or to avoid taking powerful and toxic anti-arrhythmic medications. In some cases, it may even be the initial line of treatment for certain patients. Atrial Fibrillation Ablation is typically performed using slender, flexible tubes, known as catheters, which are inserted through the veins leading to the heart.

Seeking the right medical expertise is crucial for such intricate procedures to avoid stroke and heart failure. Dr Karthigesan brings to the table a rich blend of experience and skill in performing Atrial Fibrillation Ablations, backed by an unwavering commitment to patient-centred care. Trust in his expertise to guide you on your journey towards heart health and rhythmical living.

To accurately diagnose AFib or rule out other conditions presenting similar symptoms, Dr Karthigesan may recommend several tests. These diagnostic procedures may encompass:

• Electrocardiogram (ECG)/Holter monitoring
• ELR monitoring
• Transthoracic or transesophageal echocardiogram
• Cardiac CT
• Blood tests (to test thyroid levels, for instance)
• Coronary angiography

• During the Atrial Fibrillation Ablation procedure, specialised wires, also known as electrical catheters, are placed in the heart through a groin vein and occasionally via a neck vein. More than one catheter may be required.
• In the case of RF Ablation, the sensors at the tip of the catheter apply heat energy. In the case of Cryoballoon Ablation, the balloon will deliver cold energy. Either of these is then used by the doctor to create small scars around the heart to neutralise abnormal electric signals.
• Scarring is achieved through a process of small burns or freezes. In the burning process, a technique called radiofrequency energy is employed, using heat to scar the tissue. Conversely, the freezing process involves a method known as cryoablation.
• This scarring process serves to prevent the heart from transmitting the irregular electrical signals responsible for atrial fibrillation.
• RF Ablation typically takes an average of three to four hours to complete. Cryoballoon Ablation takes around two hours to complete. In cases of recurrent atrial fibrillation, further ablation procedures may be necessary.
