Clinical information and cardiac pathology data extracted from charts and autopsy reports are displayed. Quantification of airway-related microscopic pathology was done by reviewing all sampled lung tissues and counting all airways, including bronchi and bronchioli. Age-matched control was a 6-year-old girl with unexplained sudden death with a remote history of idiopathic cardiomyopathy.
Patient 2 did not take these prescribed medications prior 5 months, owing to insurance issues.
