Peripartum myocardial infarction is uncommon but devastating in young women. Although it is generally associated with arterial dissection, pregnancy-induced hypercoagulable state can also be a major contributor. Association of patent foramen ovale (PFO) adds to this potential risk. A 29-year-old postpartum female presented with worsening chest pressure, shortness of breath and syncope. She was hypotensive and tachycardic. A ventilation perfusion imaging displayed high probability for pulmonary emboli. With elevated cardiac enzymes and echocardiogram showing wall motion abnormalities, patient underwent percutaneous coronary angioplasty for a midvessel thrombus in the left anterior descending artery. Further workup showed a thrombus straddling into the left atrium via a PFO and a deep venous thrombus in the right iliac vein. Hormonal changes in pregnancy are noted to place young women in a hypercoagulable state. Screening for PFO in this group of patients with timely intervention might prevent a major systemic event caused by paradoxical embolus.
