Left atrial appendage (LAA) closure is an interventional procedure increasingly used to prevent stroke in patients with permanent atrial fibrillation and contraindications to anticoagulation therapy. As this procedure requires a relatively immobile patient and performance of continuous and prolonged transesophageal echocardiography (TEE), it is usually performed under general anesthesia. In this case series, we describe the feasibility of prolonged TEE for percutaneous LAA closure using a new noninvasive ventilation device that can avoid the need for endotracheal intubation and general anesthesia. ⋯ Deep sedation with noninvasive ventilation may be a reasonable and safe alternative to general endotracheal anesthesia in patients requiring prolonged TEE for noninvasive cardiac procedures, including LAA closure.

Randomized Controlled Trial Comparative Study
A deliberately restricted laryngeal view with the GlideScope® video laryngoscope is associated with faster and easier tracheal intubation when compared with a full glottic view: a randomized clinical trial.
During video laryngoscopy (VL) with angulated or hyper-curved blades, it is sometimes difficult to complete tracheal intubation despite a full view of the larynx. When using indirect VL, it has been suggested that it may be preferable to obtain a deliberately restricted view of the larynx to facilitate passage of the endotracheal tube. We used the GlideScope® GVL video laryngoscope (GVL) to test whether deliberately obtaining a restricted view would result in faster and easier tracheal intubation than with a full view of the larynx. ⋯ Using the GVL with a deliberately restricted view of the larynx resulted in faster and easier tracheal intubation than with a full view and with no additional complications. Our study suggests that obtaining a full or Cormack-Lehane grade 1 view may not be desirable when using the GVL. This trial was registered at ClinicalTrials.gov: NCT02144207.
