Previously there were strict criteria about who was eligible to receive it. The results of these large clinical trials are summarized in Table 1. At Cleveland Clinic's Respiratory Institute, bronchial thermoplasty is part of the comprehensive management and treatment of asthma patients provided by our Asthma Center. Performed as an outpatient procedure, bronchial thermoplasty uses a bronchoscopically-introduced catheter to deliver precisely-controlled thermal energy to the airways. While these definitions help categorize patients and identify this subpopulation, it is important to recognize that severe asthma is a heterogeneous condition with multiple subphenotypes. In addition, recent data has demonstrated the long-term safety of the procedure as well as sustained improvements in rates of asthma exacerbations, reduction in health care utilization, and improved quality of life. There is a small risk 3. The primary outcome of interest was an increase in the AQLQ score from baseline. Boston Scientific is dedicated to transforming lives through innovative medical solutions that improve the health of patients globally. This was followed with the AIR trial, the first large-scale, multicenter randomized controlled study of BT. This article has been cited by other articles in PMC. The most common adverse event of BT is a temporary worsening of respiratory-related symptoms. The Alair System consists of an RF controller and a single-use catheter. The catheter is introduced via the working channel of the flexible bronchoscope.

Top Boston Scientific does not provide medical advice, diagnosis or treatment. It also suggested that a variable response of the ASM to thermal energy could be seen with wider clinical use.

At Cleveland Clinic's Respiratory Institute, bronchial thermoplasty is part of the comprehensive management and treatment of asthma patients provided by our Asthma Center. Does bronchial thermoplasty have any side effects? To definitively answer these questions, the AIR-2 trial was performed using a multicenter, randomized, double-blind, sham-controlled design.

The distal tip contains an expandable four-electrode basket, which is serially deployed in the airways. At Cleveland Clinic's Respiratory Institute, bronchial thermoplasty is part of the comprehensive management and treatment of asthma patients provided by our Asthma Center. Asthma patients who received bronchial thermoplasty during clinical trials have demonstrated significant improvement in their asthma symptoms as well as a reduction in the number of severe asthma flare-ups and emergency department visits. Material not intended for use in France. There was a significant improvement in prebronchodilator FEV1 percentage predicted among BT subjects during the steroid stable phase Once an activation is delivered, the basket is collapsed and the catheter is withdrawn 5 mm to the next site of treatment. AIR-2 trial A common finding of both the AIR and RISA trials was a significant improvement in asthma symptoms and quality of life despite minimal, if any, improvements in pulmonary function. It sets out that the current evidence on the safety and efficacy of bronchial thermoplasty for severe asthma is adequate to support the use of this procedure provided that standard arrangements are in place for clinical governance, consent and audit. To definitively answer these questions, the AIR-2 trial was performed using a multicenter, randomized, double-blind, sham-controlled design. The catheter contains a four-electrode basket on the distal tip and is marked at 5 mm increments.

Of note, patients treated with sham bronchoscopy did have an increase in the AQLQ score when compared to their prerandomization baseline.
