  • tissue
  • Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. (fpnotebook.com)
  • In this paper, the basics of cryothermal energy ablation are reviewed including its ability of creating homogenous lesion formation, minimal destruction to surrounding vasculature, preserved tissue integrity, and lower risk of thrombus formation. (hindawi.com)
  • The tip of the catheter is guided to the area of heart tissue that is causing the abnormal heart rhythm. (medmovie.com)
  • Then the catheter emits a pulse of painless radiofrequency energy that destroys the abnormal tissue and corrects the irregular heartbeat. (medmovie.com)
  • A widely used ablation technique that uses heat to create a larger lesion in the heart tissue more safely. (dukehealth.org)
  • Technique
  • New drugs and implantable devices (pacemakers and defibrillators) have been part of this process, but among the more dramatic developments has been the use of a heart catheterization technique called catheter ablation (CA). The heartbeat is the result of heart muscle cells transmitting an electrical signal from one cell to another. (ahajournals.org)
  • 2,3 Another technique that has been used to eliminate PAF has been left atrial ablation to encircle the PVs. (ahajournals.org)
  • Because no previous studies have directly compared the 2 ablation techniques, it has been unclear whether either technique has an advantage over the other. (ahajournals.org)
  • Medtronic
  • Some doctors in the study suggested the Medtronic catheter-ablation device could gain wide use in many of the 2.3 million Americans with A-fib. (wsj.com)
  • Medtronic hasn't announced pricing, but current catheter ablations involve insurance payments of about $25,000 to hospitals and about $2,000 to doctors. (wsj.com)
  • symptomatic
  • In some cases, it may be even appropriate to perform AF ablation as first-line therapy, particularly in selected symptomatic patients with heart failure and/or reduced left ventricular ejection fraction [ 2 ]. (hindawi.com)
  • P=0.007), and more patients in the ablation group were free from any AF (85% vs. 71%, P=0.004) and from symptomatic AF (93% vs. 84%, P=0.01). (bmj.com)
  • minimally
  • Catheter ablation provides a minimally invasive option when other approaches - such as regular checkups, lifestyle changes, brief external shocks ( cardioversion ) or medications - do not work. (umm.edu)
