Tricuspid Regurgitation and Atrial Fibrillation Secondary to Contusio Cordis: An Atypical Presentation

Abstract

The tricuspid regurgitation (TR) is most often associated with mitral valvular disease, named secondary tricuspid regurgitation. Other etiologies such as infective endocarditis, Ebstein’s anomaly, carcinoid disease and blunt chest trauma are unusual [1]. The tricuspid valve lesions caused by blunt chest trauma are rare and often widely misdiagnosed. The term “contusio cordis” is represented by the cardiac myocyte damage, fibrotic or hemorrhagic, secondary to thoracic blunt trauma. Commotio cordis, meanwhile, involves electromechanical heart disorder. In most cases, leads to ventricular fibrillation, coinciding with a critical moment in the cardiac cycleabout 20ms preceding the T wave [2]. Both presentations are usually fatal [3]. We report the case of a patient with a diagnosis of TR and atrial fibrillation (AF), secondary to contusio cordis, but with insidious and unusual late clinical evolution, diagnosed 11 years after the fact.
