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.
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.
Ablation therapy is a catheter based ablation of lesions in the heart (with radiofrequency energy, cryotherapy (destructive freezing), microwave, or ultrasound energy) to cure or control arrhythmias (see radiofrequency ablation). Ablation is usually performed during the same procedure as the electrophysiology study during which arrhythmias are ...
Symplicity HTN-1 [3] looked at outcomes in 153 patients that underwent catheter-based renal denervation. Three-year follow-up data have demonstrated an average blood pressure reduction of -33/-19mm Hg. Symplicity HTN-2 was a randomized, [2] controlled trial that compared 54 control patients with 52 patients who underwent catheter-based renal ...
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy.Cryotherapy can be used in many ways, including whole body exposure for therapeutic health benefits or may be used locally to treat a variety of tissue lesions.
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).
The devices are implanted without open heart surgery. The valve delivery system is inserted in the body, the valve is positioned and then implanted inside the diseased aortic valve, and then the delivery system is removed. The catheter-based delivery system can be inserted into the body from one of several sites. [14]
A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein . A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.
