Case Reports[Tricuspid endocarditis with right-left shunt in the atrium].
A case of tricuspid regurgitation due to endocarditis causing a right-to-left shunt through a patent foramen ovale is reported. Tricuspid valve endocarditis occurred after septic abortion and caused valvular regurgitation with dyspnea and cyanosis. ⋯ The physiopathology of these right-to-left shunts is the same as that already described during traumatic tricuspid regurgitation: reopening of the foramen ovale by the right atrial dilatation and ventricularisation of right atrial pressures. The presence of a shunt is an indication for surgery.
