Aims Transoesophageal echocardiography (TEE) may require patient sedation, eventually leading to respiratory depression, a risky condition in severe cardiac disease. Non-invasive ventilation (NIV) has been applied during diagnostic manoeuvres, but its use during TEE has not been reported. We describe NIV-aided continuous TEE monitoring under sedation in the supine position in three consecutive orthopnoeic patients with severe aortic valve stenosis: two of them underwent percutaneous aortic valve implantation, and one underwent aortic valvuloplasty. Methods and results The TEE probe was passed through a hole performed with a surgical cutter in an NIV face-mask. Pulsoximetry, heart rate, arterial blood pressure, respiratory rate, arterial blood gases, patients' comfort, and patient's sedation were monitored throughout the procedure. Percutaneous aortic valve implantation procedures lasted almost 2 h, while the valvuloplasty procedure lasted 70 min. Non-invasive ventilation and continuous TEE were performed throughout the procedures without technical problems or respiratory or haemodynamic complications, and all patients felt always comfortable. Conclusion Non-invasive ventilation through a modified face-mask allowed to perform continuous TEE examination and to avoid tracheal intubation and general anaesthesia in three high-risk patients undergoing beating heart treatment of aortic valve stenosis.
