Images in cardiovascular medicine. Esophageal diverticulum illustrated by barium swallow during left atrial catheter ablation for atrial fibrillation.

Left atrial radiofrequency catheter ablation guided by a 3-dimensional electroanatomic mapping system (CARTO, Biosense-Webster, Diamond Bar, Calif) was performed in a 67-year-old woman with paroxysmal atrial fibrillation. To avoid delivery of radiofrequency energy near the esophagus, the patient was asked to swallow 5 cm of barium paste (E-Z-EM, Lake Success, NY) before conscious sedation, as d...

Anatomical Basis for the Mobility of the Esophagus: Implications for Catheter Ablation of Atrial Fibrillation

We present autopsy data from a patient that illustrates the anatomical factors that allow the esophagus to be a mobile structure, especially with respect to the posterior left atrial wall.

Left Atrial Anatomy Relevant to Catheter Ablation

The rapid development of interventional procedures for the treatment of arrhythmias in humans, especially the use of catheter ablation techniques, has renewed interest in cardiac anatomy. Although the substrates of atrial fibrillation (AF), its initiation and maintenance, remain to be fully elucidated, catheter ablation in the left atrium (LA) has become a common therapeutic option for patients...

Impending rupture of the left atrium after impaction of left atrial ablation catheter.

A 60-year-old male presented with chronic atrial fibrillation. A trans-femoral catheter ablation was planned. The catheter was impacted in the left atrial wall (Fig. 1). Consequently, the procedure was interrupted before achieving resynchronisation. Catheter withdrawal was only possible after median sternotomy and closed manipulation of the catheter to release it.

Evaluation of the Pulmonary Veins and Left Atrial Volume using Multidetector Computed Tomography in Patients Undergoing Catheter Ablation for Atrial Fibrillation

Catheter ablation is an evolving treatment option in patients with atrial fibrillation. Contrast enhanced electrocardiogram-gated multi-detector computed tomography (MDCT) has rapidly evolved over the past few years into an important tool in the diagnosis of coronary atherosclerosis. There is increasing recognition that MDCT is a useful tool to evaluate non-coronary structures, such as cardiac ...

Optimal Transseptal Puncture Location for Robot-Assisted Left Atrial Catheter Ablation

BACKGROUND The preferred method of treatment for atrial fibrillation (AF) is by catheter ablation, in which a catheter is guided into the left atrium through a transseptal puncture. However, the transseptal puncture constrains the catheter, thereby limiting its manoeuvrability and increasing the difficulty in reaching various locations in the left atrium. In this paper, we address the problem o...
