SURGICAL TREATMENT OF BLUNT CARDIAC TRAUMA IN CHILDREN： REPORT OF 2 CASES AND REVIEW OF LITERATURES

Objective Summarizing the clinical experience of surgical treatment in 2 cases of blunt cardiac trauma and reviewing the relevant literaturesMethods A 6-year-old girl was diagnosed muscular ventricular septal defect and left ventricular aneurysm 2d after automobile accident and underwent ventricular septal defect repair 2 weeks after injury. Another 9-year-old boy was diagnosed severe mitral regurgitation resulted from rupture of posterior papillary muscle 9d after automobile accident and underwent mitral valvuloplasty 2 weeks after injury. Results Heart function of the first patient was in New York Heart Association (NYHA) class Ⅰ, echocardiography showed no residual septal defect and the size of left ventricular aneurysm reduced. Heart function of the second patient is in NYHA class Ⅱ, echocardiography showed mild mitral regurgitation. Conclusion Blunt traumatic heart disease occurs either because of heart compression between sternum and the spine and/or because of myocardial contusion; A more aggressive strategy with surgical treatment earlier before deterioration of heart function is advocated; Earlier surgical correction of anatomic deformity will achieve a good result and a long time follow-up is necessary.
