Brief Summary

This study will evaluate a new imaging technology, called optical coherence tomography (OCT) to examine the asthmatic airways before and after bronchial thermoplasty, which is a new treatment option for severe asthmatic patients. The aim of this study is to learn more about how airways respond to this new treatment. In the future the investigators hope OCT will aid clinicians in the initial assessment, management and long-term follow up of patients receiving bronchial thermoplasty.
