Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Microwave ablation is a form of thermal ablation used in interventional radiology to treat cancer. MWA uses electromagnetic waves in the microwave energy spectrum (300 MHz to 300 GHz) to produce tissue-heating effects.
It is important for patients not to eat or drink for up to 12 hours before the procedure. This is to prevent vomiting, which can result in aspiration, and also cause severe bleeding from the insertion site of the catheter. Failure to follow this simple preparation may result in dangerous consequences.
Alcohol septal ablation (ASA) is a minimally invasive heart procedure to treat hypertrophic cardiomyopathy (HCM). [1]It is a percutaneous, minimally invasive procedure performed by an interventional cardiologist to relieve symptoms and improve functional status in eligible patients with severely symptomatic HCM who meet strict clinical, anatomic and physiologic selection criteria.
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
