Bronchial Thermoplasty: A Decade of Experience: State of the Art

Abstract

Bronchial thermoplasty (BT) delivers targeted radiofrequency energy to bronchial airway walls and results in the partial ablation of the airway smooth muscle that is responsible for bronchoconstriction. It is approved for the treatment of severe persistent asthma. Multiple, large clinical trials including a recent "real-world" study demonstrate significant improvements in asthma-related quality of life, reduction in asthma exacerbations, emergency department visits, and hospitalizations after BT that is sustained out to 5 years. In this article, we review the state of the art of BT treatment in severe persistent asthma and share a decade of BT research and clinical experience. We share our personal experience and introduce the three "I"s (identification, implementation, and intense follow-up) that we believe promote successful patient outcomes and help build a successful BT program.
