Thoracoscopic Radiofrequency Fragmentation of the Left Atrium as a Bridge to Decision Before Heart Transplant.

Objectives: Atrial fibrillation and congestive heart failure can provoke and aggravate each other. Often the boundaries between those diseases are ambiguous, and successful diagnosis is initially elusive. However, the last stage of congestive heart failure can lead the patient to heart transplant.

The Technology of Homogeneous Scar Tissue Creating as a Result of Ablation of the Atrial Wall with a Radiofrequency Bipolar Clamp: an Experimental and Clinical Study.

Introduction: The objective of this study was to develop a radiofrequency ablation technique to create a homogeneous scar tissue in the atrial myocardium.

Methods: In the double-blinded morphological stage of the study, the left atrial appendage was used as an anatomical model to investigate the efficacy of one experimental and two conventional techniques to create ablation lines. Then, these lines were studied by morphologists.
