# A Novel Use of a Not So “EZ-Blocker” For Lung Isolation During a Direct Transaortic Transcatheter Aortic Valve Replacement

## TL;DR

This paper describes a novel use of an endobronchial blocker for lung isolation during a complex heart valve procedure.

## Contribution

The paper introduces a new application of the 'EZ-blocker' for lung isolation in a challenging surgical setting.

## Key findings

- A direct transaortic transcatheter aortic valve replacement required lung isolation.
- The 'EZ-blocker' was used in a novel way to achieve adequate lung isolation.
- The approach maintained patient safety while overcoming spatial constraints.

## Abstract

Alternate access transcatheter aortic valve replacement presents unique challenges for anesthesiologists, including the possible need for lung isolation while working with space constraints around the patient's airway. Troubleshooting lung isolation in these cases can be challenging, requiring quick thinking and adaptability while maintaining patient safety. We present a case of direct transaortic transcatheter aortic valve replacement with an endobronchial blocker ("EZ-blocker") used for lung isolation that required a novel use of the "EZ-blocker" to achieve adequate lung isolation.
