Whether a mapping algorithm "Ripple-mapping" is able to rapidly identify the areas of long-duration multicomponent electrograms which constitute the targets for ablation for an automated s...
This study is an observational study without any hypothesis testing. It intended to observe the clinical application of electrophysiological mapping and catheter ablation of atrial tachyca...
Radiofrequency catheter ablation is effective in the treatment of patients with paroxysmal atrial fibrillation. In order to reduce the recurrence rate after catheter ablation, we propose t...
Objective: The purpose of this study is to compare the efficacy and safety of complex fractionated atrial electrocardiograms (CFAEs) guided ablation to pulmonary vein isolation based ablat...
In this clinical investigation, the safety and feasibility of the novel EnSite™ HD Grid Catheter mapping system for advanced high-density three-dimensional mapping will be studied in pat...
We present a case of redo atrial fibrillation (AF) ablation for pulmonary vein reconnection. In mapping of posterior wall of left upper pulmonary vein (LUPV) with HD grid, a new and unique multipolar ...
Catheter ablation is an effective therapeutic strategy for atrial tachycardia (AT). However, it is clinically difficult to map a difficult-to-induce or nonsustained AT for distinguishing between AT an...
Catheter ablation (CA) is a well-established therapeutic option for patients with recurrent symptomatic atrial fibrillation (AF). Data on gender-related differences are limited with regard to baseline...
Catheter ablation is considered as the mainstay treatment for patients with symptomatic atrial fibrillation (AF). We aimed to determine the predictors of 30-day readmission after catheter ablation for...
The right atrial appendage (RAA) is a rare site of focal atrial tachycardia (AT). Sometimes, catheter ablation cannot successfully be accomplished at this location due to the difficulty in reaching th...
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.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
A hindrance to the passage of fluids through a CATHETER.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
Infections resulting from the use of catheters. Proper aseptic technique, site of catheter placement, material composition, and virulence of the organism are all factors that can influence possible infection.
