title: Tricuspid insufficiency due to nonpenetrating trauma.
abstract: This case of tricuspid insufficiency due to nonpenetrating trauma involved a male patient who had received major chest trauma in an automobile accident, had a nonholosystolic murmur that increased slightly during inspiration on standing, and tranient electrocardiographic findings of right bundle branch block. Unlike findings in previous cases, the right atrial V wave was not dominant and was less than 8 mm Hg. An echocardiogram indicating right ventricular volume overload was an essential diagnostic tool that led to cardiac catheterization and definitive diagnosis.
