Clinical Value of Left Atrial Appendage Flow for Prediction of Successful Catheter Ablation for Persistent Atrial Fibrillation

2014-07-23 21:08:46 | BioPortfolio

Summary

The purpose of this study was to determine whether left atrial appendage flow velocity, as determined using trans esophageal echocardiography (TEE), predicts the outcome after catheter ablation of persistent Atrial fibrillation( pAF).

Description

40 PAF patients underwent 3D mapping and ablation. A stepwise approach including circumferential pulmonary vein (PV) isolation, continuous complex-fractionated electrogram (CFE) ablation and linear ablation was performed by the same operator. The procedural end point was termination of persistent AF by catheter ablation, either by conversion directly to sinus rhythm or to atrial tachycardia. Left atrial appendage (LAA) peak flow velocities were measured with transesophageal echography and averaged within each RR interval of 10 consecutive cardiac cycles.

Medical and Biotech [MESH] Definitions

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).

Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.

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)

Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)

A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.
