If a large enough residual, it could lead to chronic
pulmonary hypertension, with chronic right heart strain
and/or in some instances, shunting of blood (at the atrial level) from the right heart to the left heart through a patent foramen ovale. For all of the preceding reasons, and especially with the recent onset of chest pain, you should have a cardio-pulmonary reevaluation at this time, with a CT scan and an ECHO to assess pulmonary hypertension.
