Catheter ablation may be recommended for a recurrent or persistent arrhythmia resulting in symptoms or other dysfunction. Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [1] Pulmonary vein isolation by transcatheter ablation can restore sinus ...
Radiofrequency ablation is a minimally invasive procedure used in the treatment of varicose veins. It is an alternative to the traditional stripping operation. Under ultrasound guidance, a radiofrequency catheter is inserted into the abnormal vein and the vessel treated with radio-energy, resulting in closure of the involved vein.
The main symptom of AVNRT is the sudden development of rapid regular palpitations. [1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system.

Pulmonary vein isolation ablation technology has used thermal methods (radiofrequency ablation or, less often, cryoablation) to destroy pulmonary vein cells. [5] As with thermal methods of ablation, in pulsed field ablation, a thin, flexible tube ( catheter ) is inserted into a blood vessel in the groin and threaded up into the heart to ablate ...
An access site that will allow catheters to be passed to the heart via an artery or vein is shaved and cleaned, usually in the groin. The blood vessels used to reach the heart (the femoral or subclavian veins , and sometimes the femoral artery ) are punctured before a guidewire and plastic sheath are inserted into the vessel using the Seldinger ...

Significant complications of the operation include bleeding, heart problems (heart attack, arrhythmias), stroke, infections (often pneumonia) and injury to the kidneys. Three coronary artery bypass grafts, a pedicled LITA to LAD and two saphenous vein grafts – one to the right coronary artery system and one to the obtuse marginal system.
Delayed ejaculation can also be caused by desensitization of the penis. Dr. Jesse Mills , director of the UCLA Men’s Health Clinic, tells Yahoo Life that, like all other parts of our bodies ...
