Right-to-left shunting through a patent foramen ovale is usually associated with spontaneous (2) or induced (3) pulmonary hypertension. In the absence of pulmonary hypertension and, therefore, in the absence of a right-to-left pressure gradient, right-to-left atrial shunting is caused by preferential redirecting of flow from the inferior vena cava toward the patent foramen ovale.A persistent eustachian valve can cause (in addition to pericardial effusion, which results in an anatomic distortion of the right atrium) interatrial right-to-left shunting...References1.
