Bronchoscopy in the Pediatric Cardiovascular Patient with Persistent Respiratory Pathology

<b>Background:</b> Patients with congenital heart disease can associate malformations. The most frequent complications are those related to the airways, which produce prolonged cardiovascular postoperative. <b>Objectives</b>: Describe pathology, bronchoscopy indications, and findings in patients with heart pathology and persistent breath failure to improve prognosis and determine an early treatment. <b>Methods</b>: Retrospective descriptive study of bronchoscopies performed during 24 years in pediatric patients with congenital heart disease with surgery indication and persistent respiratory symptomatology. <b>Results:</b> We performed 199 fibrobronchoscopies in 144 patients, with an average of 1.4 fibrobronchoscopies per patient. A total of 58% were male. The mean age was 27.5 months (5 days-13 years). Valvular disease was the most frequent congenital heart disease, followed by the transposition of large vessels. The most frequent indications were stridor (42.7%) and persistent atelectasis (24.6%), followed by extubation failure (12.4%) and pump output (6.2%). The majority of the findings were found in the upper airway (56%), with a clear predominance of malacias (32%), while in the lower airway, extrinsic compression was highlighted (42%). <b>Conclusions</b>: Flexible fiberoptic bronchoscopy is a useful and rapid method for the diagnosis of airway malformations associated with congenital heart diseases that may have a relevant role in its management and prognosis.
