BACKGROUND Drug therapy is mostly employed in the management of supraventricular tachycardias (SVTs). However, radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of SVTs. The current study is aimed at sharing our experience of 320 patients who presented with SVTs, and were treated with radiofrequency catheter ablation. METHODS This descriptive stu...

Pulmonary vein ablation with a single-tip catheter remains long and complex. We describe a typical case of a novel efficient technique with a decapolar ring catheter utilizing alternating unipolar/bipolar radiofrequency energy. Voltage analysis and electrical mapping demonstrate the potential for antrum ablation and pulmonary vein isolation.

Catheter ablation of atrial fibrillation is difficult when the left atrium is compressed by the vertebra. The heart may shift forward, and compression of the left atrium may be relieved in the left lateral decubitus position. Therefore, catheter ablation could be performed in the left lateral decubitus position even in such cases.

Pulmonary vein stenosis, which is one of the rare complications of radiofrequency catheter ablation for atrial fibrillation, has various symptoms. Here, we report a rare case of massive hemoptysis due to pulmonary vein stenosis following radiofrequency catheter ablation, which was successfully managed with pneumonectomy.
