Video-Assisted Thoracoscopic Pulmonary Vein Isolation Versus Percutaneous Catheter Ablation in Atrial Fibrillation Trial (VATCAT)

July 6, 2016 updated by: B. Oude Velthuis, Medisch Spectrum Twente

Recent studies demonstrated that radiofrequency isolation of the pulmonary veins (PVI) and surgically video assisted thorascopic pulmonary vein isolation (VATS-PVI) are acceptable or even superior alternatives to antiarrhythmic drug therapy in patients with symptomatically paroxysmal atrial fibrillation (AF). However, data comparing effectiveness in both interventions are limited.

The investigators want to compare the effectiveness of PVI and VATS-PVI. Secondary objectives are to compare the duration of hospitalization, quality of Life, cost and to compare the satisfaction of the patients.

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Percutaneous therapy
For catheter ablation, we used irrigated 4mm RF-ablation catheters, at a maximum power of 30-35Watt, an irrigation rate of 20 mL/min. PV isolation was performed by wide circumferential ablation, encircling all ipsilateral PVs.
Active Comparator: VATS therapy
A bilateral video-assisted thoracoscopic (VATS) pulmonary vein isolation and left atrial appendage (LAA) excision is performed under general anaesthesia and double-lumen endotracheal ventilation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recurrence of AF
Time Frame: one year
The percentage of patients without a recurrence of AF, without antiarrhythmic drugs (AADs), within a follow-up period of at least 12 months after a stabilisation period of 90 days after the initial procedure. An episode of AF is defined as an episode of at least 30 seconds duration.
one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment impact
Time Frame: one year
Secondary objectives include the duration and cost of hospitalization, discomfort during admission, assessment and experienced AF burden during follow-up of procedural impact on the patient and time to recurrence after intervention. A complication register will also be kept.
