Surgeons have contributed studies of the pathophysiology and treatment of arrhythmias in experimental animals and patients during thoracotomy. This research has involved epicardial1 and endocardial2 pacemakers and implantable cardioverter–defibrillators (ICDs).3 Surgeons helped to define the mechanisms and ablation methods for supraventricular arrhythmias (including Wolff-Parkinson-White syndrome… View more

Heart Failure
Author(s): John M Miller , Anil V Yadav Added: 3 years ago
In the nearly 30 years since Wellens et al. categorized most of the currently used electrocardiographic (ECG) criteria for distinguishing supraventricular tachycardia (SVT) with aberrant interventricular conduction from ventricular tachycardia (VT),1 there have been relatively infrequent and largely incremental enhancements to the art and science of making this distinction. In most published… View more

The Biology of Cryotherapy Cryotherapy is the use of cooling and freezing in living tissue to affect cellular function and activity. To produce cryotherapeutic temperatures, heat energy is removed from the tissue, rather than 'injecting cold energy into the tissue. Multiple factors influence the effectiveness of catheter-based cryotherapy. Chief among these are tip contact (to remove heat from… View more

Electrophysiology & Arrhythmia

For many cardiac arrhythmias, catheter cryoablation is now a safe and effective alternative to RF ablation. Freezor┬«, a 7F cryocatheter, has been in clinical use in Europe, Canada and the US for several years. In that time, it has established a record of safety and effectiveness in the treatment of arrhythmias, particularly in peri-nodal procedures. With its demonstrated safety profile -… View more
