Training program of interventional pulmonology fellowships: USA.

Interventional pulmonary (IP) is an emerging subspecialty of pulmonary medicine which focuses on procedures of the airway, lung, and pleura. As the number of advance procedures increases with the growth of this field, additional formal training is required to offer the full complement of techniques. IP fellowship is a dedicated 12 months fellowship in the United States which occurs after pulmonary/critical care fellowship. There have been several recent milestones in this field which include validated exams based on didactic knowledge and structural organization of fellowship organizations.
