Totally Endoscopic Ablation of Atrial Fibrillation

18:11 EDT 27th March 2015 | BioPortfolio


Primary Objective To evaluate the efficiency of totally endoscopic ablation of AF compared to rate control management of AF.

Secondary Objectives

Does totally endoscopic ablation:

- reduce atrial fibrillation symptoms?

- increase working capacity and improve quality of life?

- improve atrial function?

- reduce the risk for stroke?


This is a randomized open controlled single centre study that involves 60 patients (men and women) over the age of 50 years with longstanding persistent AF of more than one year duration and in the absence of other severe cardiopulmonary disease. One of the participating investigators informs the patient, both verbally and in writing, about the study and what participation in the study involves. The patient will be given time to ask questions and to consider study participation and can be enrolled in the study after signing and dating written Informed Consent. Study duration per patient is 12 months.

After inclusion, the patient will be divided into one of two groups, treatment group or control group, according to block wise randomization. The patient will be asked to complete two health related questionnaires SF 36 and SCL and a transthoracic echocardiography will be conducted together with an exercise test.

The patients will thereafter be assessed according to randomisation. Irrespective of group, the patients will be rescheduled for a visit within two months for totally endoscopic ablation and Reveal implantation or just Reveal implantation (control group). All patients will then be assessed during follow-ups after 1, 3, 6 and 12 months.

Medical and Biotech [MESH] Definitions

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)

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).

Control of bleeding performed through the channel of the endoscope. Techniques include use of lasers, heater probes, bipolar electrocoagulation, and local injection. Endoscopic hemostasis is commonly used to treat bleeding esophageal and gastrointestinal varices and ulcers.

Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.

An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.
