Indications, Safety, and Warnings
The Cardioblate CryoFlex Surgical Ablation System
Indications for Use
The Cardioblate® CryoFlex™ Surgical Ablation System is intended for minimally invasive cardiac surgical procedures, including the treatment of cardiac arrhythmias. The Cardioblate CryoFlex 7cm, 10cm, and 10-S probes plus the Cardioblate CryoFlex Clamp and Cardioblate CryoFlex Surgical Ablation Console freeze target tissue and block the electrical conduction pathways by creating an inflammatory response and cryonecrosis.
Contraindications
The Cardioblate CryoFlex Surgical Ablation Probe is not designed for use inside a beating heart.
Adverse Events or Complications
Potential adverse events with this device are similar to other cardiac surgery procedures and may include the following:
- Bleeding
- Re-operation
- Extension of extracorporeal bypass
- Heart rhythm disturbances (atrial and/or ventricular)
- Effusion
- Pericarditis
- Cardiac tamponade
- Pleural effusion
- Mediastinitis
- Conduction disturbances (SA/AV node)
- Acute ischemic myocardial event
- Thrombus formation
- Low cardiac output
- Stroke
- Renal, gastrointestinal, or respiratory complications
- Sepsis
- Adjacent structural damage
- Death
Avoid contact between the cryoablation probe and the phrenic nerve to avoid injury. Perioperative heart rhythm disturbances (atrial and/or ventricular)
Cryoablation involving coronary vessels has been associated with subsequent clinically significant arterial stenosis. It is unknown whether Cryoablation with the Cardioblate CryoFlex Surgical Ablation Probe will have such an effect, but as in all such procedures, care should be taken to minimize unnecessary contact with coronary vessels during cryoablation.
