Catheter ablation procedure involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein. The catheters are then advanced towards the heart. The catheters have electrodes at the tips that can measure the electrical signals from the heart.
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]
Loyola Medicine, also known as Loyola University Health System, is a quaternary-care system with a 61-acre (25 ha) main medical center campus in the western suburbs of Chicago, in the U.S. state of Illinois. The medical center campus is located in Maywood, 13 miles (21 km) west of the Chicago Loop and 8 miles (13 km) east of Oak Brook.
Once the catheter is in and all preparations are complete elsewhere in the lab, the EP study begins. The X-ray machine will give the doctor a live view of the heart and the position of the electrodes. He will guide the (steerable) electrodes to the correct position inside the heart.
Once a catheter is in place, it can be used to perform a number of procedures including angioplasty, PCI (percutaneous coronary intervention) angiography, transcatheter aortic valve replacement, balloon septostomy, and an electrophysiology study or catheter ablation.
By changing the diagnostic catheter to a guiding catheter, physicians can also pass a variety of instruments through the catheter and into the artery to a lesion site. The most commonly used are 0.014-inch-diameter (0.36 mm) guide wires and the balloon dilation catheters. [citation needed]
Fairfield Medical Center recently introduced pulsed field ablation (PFA) therapy for the treatment of atrial fibrillation (afib).
Cryoablation is used in two types of intervention for the treatment of arrhythmias: (1) catheter-based procedures and (2) surgical operations. A catheter is a very thin tube that is inserted into a vein in the patient’s leg and threaded to the heart where it delivers energy to treat the patient’s arrhythmia.
