Course 9: Fontan Conversion and Maze Procedure

Course Directors: Jeffrey P. Jacobs, St Petersburg, FL, and Constantine Mavroudis, Orlando, FL


This hands-on wet lab will familiarize the clinician with the different types of arrhythmias that patients with congenital heart disease—specifically, single ventricle physiology—may experience. The course will cover the mechanisms of action, surgical ablation, and therapeutic pacemaker strategies.

Attendees will use porcine hearts to examine the landmarks used for intraoperative electrophysiologic mapping, applying cryoablation lesions, and lead placement strategies for pacemaker implantation. Actual cryoablation probes with freezing capabilities will be available to give attendees the experience necessary to perform this operation in humans.

Learning Objectives
Upon completion of this activity, participants should be able to: 

  • Explain the principles and mechanisms of various atrial arrhythmias
  • Review the clinical characteristics of therapeutic arrhythmia surgery
  • Demonstrate the application of cryoablation lesions on the heart
  • Identify the various atrial to pulmonary artery Fontan connections and learn how to manage the various confounding anatomic challenges that complicate Fontan conversion surgery
