Myocarditis in viral infection of dengue in pediatrics.

Miocarditis en la infección viral del dengue en pediatría.

Objective: To perform a systematic review on dengue virus infection (DENV), with cardiovascular involvement, in the pediatric population, in order to describe and establish useful criteria for diagnosis and management. Methods: In a database search, Embase, Medline, PubMed, The Cochrane Library and LILACS. With limits and keywords that included randomized clinical trials and cardiovascular involvement in viral infection by DENV. Conclusions: DENV infection with myocardial compromise in pediatrics is a great clinical challenge. It presents multiple manifestations, where clinical suspicion, the different evolution and course of the disease together with the use and interpretation of diagnostic tests different from Biopsy, may throw clues or divert attention from the actual organ involvement observed. The pathophysiology of myocardial compromise beyond shock in the pediatric patient should be understood in order to perform its evaluation. The possibility of dilated cardiomyopathy should be taken into account in DENV and refractory shock, associated with signs and symptoms of congestive heart failure. Early detection, immediate resuscitation, entry into the intensive care unit, and avoidance of aggressive intravenous fluid therapy are crucial life-saving measures and can improve patient survival. Adequate classification and diagnostic criteria define the essential management of support, avoiding fatal results.
