Article Description:

This is a retrospective case-control study of the use of non-invasive ventilation during left atrial appendage occlusion (LAAO).

Summary:

  • During LAAO, transoesophageal echocardiography (TEE) is required in all patients to guide the transseptal puncture and to have a full view of the LAA.
  • Percutaneous LAAO is frequently performed in old, frail patients with several comorbidities which increase the risks of complications of general anesthesia.
  • The possibility of undergoing LAAO under procedural sedation is attractive.
  • The authors compared 11 patients undergoing LAAO under sedation with assisted spontaneous ventilation using the Janus Mask, a device designed for endoscopic procedures, with 11 patients underwent LAAO received general anaesthesia. 
  • Patients in the Janus Mask group showed increased PaCO2 which led to a transient pH decrease 45 min after the beginning of the procedural sedation
  • No differences in the intraoperative haemodynamic parameters, oxygenation and discharge criteria were noted.
  • Surgeons and anaesthesiologists showed comparable satisfaction with both techniques of anaesthesia.
  • Three cases in the Janus mask group developed transient intraoperative apnoea which were treated with reduction of sedation without further apparent complications.
  • This preliminary study demonstrated the feasibility and safety of the procedural sedation with assisted spontaneous ventilation using the Janus Mask as an alternative to general anaesthesia during the LAAO procedures.
