About this trial
The purpose of this study is to demonstrate the safety and effectiveness of the Cardioblate iRF and CryoFlex hand held devices for the treatment of non-paroxysmal atrial fibrillation (AF).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
History of non-paroxysmal AF (persistent or longstanding persistent)
Concomitant indication for non-emergent open-heart surgery, eg,
Coronary artery bypass grafting
Valve repair or replacement
Disqualifiers
Wolff-Parkinson-White syndrome
New York Heart Association (NYHA) Class = IV
Left Ventricular Ejection Fraction ≤ 30%
Need for emergent cardiac surgery (ie, cardiogenic shock) or redo open heart surgery
Trial design
Single group
Treatments tested in this trial
Surgical Ablation
Procedure/SurgeryIn addition to the concomitant surgery, subjects are required to have amputation or closure (with sutures or ligation) of the left atrial appendage.The Cox Maze IV lesion set is required to be performed.
Cardioblate and Cryoflex hand held devices
DeviceThe Cardioblate hand held devices consist of the Cardioblate iRF and Cryoflex surgical ablation devices.
