Further study details as provided by Boston Children’s Hospital:

Primary Outcome Measures:
  • Total fluoroscopy time [ Time Frame: During the Ablation procedure ]

Secondary Outcome Measures:
  • Total Radiation Exposure [ Time Frame: During Ablation Procedure ]

Estimated Enrollment: 75
Study Start Date: January 2009
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
Control Patients - Undergo ablation procedures with radiation/fluoroscopy only
Experimental: 2
Study Group Patients - Undergo ablation procedures using intracardiac echocardiography and 3D navigational system in addition to radiation.
Device: Intracardiac echocardiography and 3D navigational system
Patients assigned to the intervention group will receive both intracardiac echocardiography as well as a 3D navigational system in addition to fluoroscopy during their ablation procedure.
