Who Should Attend?

• Cardiac electrophysiologists
• Cardiac surgeons
• Pediatric electrophysiologists
• Other cardiologists
• Physician assistants
• Nurse practitioners
• Registered nurses
• Members of industry

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

• Use the surface ECG to identify potential sites of VT origin, and plan optimal mapping strategies prior to the procedure
• Understand the differences between and limitations of transvenous and percutaneous transpericardial approaches to epicardial mapping of outflow tract VT
• Use 3-D echo to construct anatomic mapping templates and guide ablation of outflow tract VT

Patient Medical History
The patient is a 37-year-old woman with frequent PVCs noted on routine examination several months ago. She complained of progressive generalized fatigue and an irregular pulse. She had no history of dizziness, syncope or sustained palpitations. A 24-hour Holter Monitor demonstrated frequent uniform PVCs comprising 23% of all QRS complexes. A 12-lead electrocardiogram documented a LBBB - right inferior axis QRS configuration with a broad R wave in V1 and V2 most compatible with an origin in the left ventricular outflow tract or pulmonary artery. An echocardiogram demonstrated global left ventricular hypokinesis with an ejection fraction of 40%. A coronary angiogram performed one month ago was unremarkable. Treatment with beta blockers resulted in no change in symptoms, ventricular function, or the frequency of ectopic beats. She was considered to have a possible tachycardia mediated myopathy, and was referred for catheter ablation.

This program is part of the Heart Rhythm Society's SCA 360° Initiative.
