An 82-year-old frail patient with severe aortic stenosis, heart failure, hypoxemia, and hiccups underwent transcatheter aortic valve implantation (TAVI) under sedation with dexmedetomidine, fentanyl, and ketamine. High-flow nasal oxygenation effectively prevented hiccups and associated body movements, and prevented upper airway obstruction and respiratory depression during the procedure. This therapy shows potential usefulness during cardiac catheterization under monitored anesthesia care in elderly frail patients with reduced cardiopulmonary function.
