Area of Science:

  • Cardiac Electrophysiology
  • Minimally Invasive Cardiac Surgery

Background:

  • Atrial fibrillation necessitates effective substrate modification.
  • The Cox maze IV procedure is a standard surgical treatment for atrial fibrillation.
  • Creating a complete box lesion is crucial for procedural success.

Purpose of the Study:

  • To describe a novel maneuver for creating the box lesion in the Cox maze IV procedure.
  • To detail the use of a single radiofrequency clamp for this maneuver.

Main Methods:

  • A single radiofrequency clamp is utilized.
  • The clamp engages the right pulmonary veins.
  • The clamp is advanced under the superior vena cava through the transverse sinus to encompass the left pulmonary veins and atrial roof.

Main Results:

  • The described maneuver facilitates the creation of the box lesion.
  • Desirable transmurality of the created lesion is consistently achieved.
  • This technique simplifies the box lesion creation process.

Conclusions:

  • This single-clamp maneuver is an effective method for achieving the box lesion in Cox maze IV procedures.
  • The technique ensures lesion transmurality, potentially improving outcomes for atrial fibrillation patients.
