Bronchial Thermoplasty is a procedure that involves the delivery of radiofrequency energy during bronchoscopy to airways in order to selectively ablate airway smooth muscles. Bronchial Thermoplasty was approved by the FDA in 2010 and remains the only device based non-pharmacological treatment approach for severe asthma. We appraise the trials leading to the approval of Bronchial Thermoplasty in light of the FDA approval process. Current international guidelines regarding use of Bronchial Thermoplasty and emering pharmacological options for severe asthma are reviewed.
