Ablation or Surgery for Atrial Fibrillation (AF) Treatment

2014-07-24 09:17:59 | BioPortfolio


The purpose of this study is to compare 2 invasive strategies for Atrial Fibrillation treatment, Endocardial catheter ablation isolation of the Pulmonary veins versus minimally invasive thoracoscopic surgical epicardial isolation. Both strategies are in use for several years now, and have been reported as a successful strategy with success rates of 60-90%. However, it is not known which technique is preferable in a given patient population in terms of efficacy to cure AF, safety, or patient discomfort. Therefore, in the present trial a randomized study is proposed to provide more insight into the relative merits of both techniques


Atrial Fibrillation is the most common cardiac arrhythmia, affecting millions of people around the world. It is a large burden on health care resources and may even lead to a shorter life expectancy. Drug treatment has been found insufficient and sometimes even hazardous to the pt. Traditionally, there was only one invasive approach available, being MAZE 3 procedure by means of full open chest cardiac surgery. This was a very invasive approach, limited to only a few skilled surgeons, with insufficient options to treat large pt volume.

With the discovery that AF often is initiated and maintained by electrical instability inside and around the Pulmonary Veins, catheter ablation is now a widely accepted early invasive strategy to cure AF. Success rates of 60% to 90% have been reported, depending on technique employed and the type of AF (Resp, chronic versus paroxysmal)

Medical and Biotech [MESH] Definitions

Removal of tissue by vaporization, abrasion, or destruction. Methods used include heating tissue by hot liquids or microwave thermal heating, freezing (CRYOABLATION), chemical ablation, and photoablation with LASERS.

Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.

Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).

A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)

Diminution or cessation of secretion of one or more hormones from the anterior pituitary gland (including LH; FOLLICLE STIMULATING HORMONE; SOMATOTROPIN; and CORTICOTROPIN). This may result from surgical or radiation ablation, non-secretory PITUITARY NEOPLASMS, metastatic tumors, infarction, PITUITARY APOPLEXY, infiltrative or granulomatous processes, and other conditions.
