Clinical spectrum of previously undiagnosed pediatric cardiac disease

Previously undiagnosed pediatric cardiac disease represents a clinical challenge for the emergency physician. The clinical presentation of these disorders canmimic other conditions of the respiratory, gastrointestinal and neurologic systems at a timewhen the need for early identification and treatment is at a premium. A high index of suspicion and superb clinical acumen is required to make a timely diagnosis and initiate optimal care. Methods: A retrospective chart review using explicit criteria and a structured data collection process was performed on all children presenting with previously undiagnosed cardiac disease over a five and half year period. Results: Thirty-six patients were identified over a five and a half year period representing one patient per 4838 pediatric ED presentations. A diverse set of chief complaints, triage categories, clinical presentations and diagnoses were identified. Undiagnosed congenital lesions, acquired cardiac disease, dysrhythmias and infectious diseases of the heartwere represented. The need for surgical intervention (22%) andmortality (6%) was substantial. Conclusion: In the aggregate, these conditions occur at an important rate and represent a high risk subset of pediatric patients presenting to the emergency department. Individually, the conditions occur infrequently and 'pattern recognition' may not aid the clinician. Early diagnosis and prompt intervention is important in this population. (c) 2019 Elsevier Inc.
