Reversible Cerebral Vasoconstriction Syndrome and Ischemic Stroke Secondary to Peripartum Cardiomyopathy - Report a Rare Case.

Acute cardioembolic stroke is a rare presentation of peripartum cardiomyopathy. We present an unusual case of peripartum cardiomyopathy, that subsequently developed cardioembolic ischemic stroke and reversible cerebral vasospasms.  A 26-year-old G1P1 caucasian woman presented to the emergency department 10 days after a spontaneous vaginal delivery with the clinical and physical presentation of acute heart failure. Brain natriuretic peptide (BNP) level was >8000 pg/mL. Transthoracic echocardiogram (TTE) demonstrated global left ventricular hypokinesis, reduced ejection fraction (EF) 22% with grade I diastolic dysfunction and apical thrombus. On hospital day two of her heart failure exacerbation admission, a code stroke was activated for aphasia and confusion. She received an IV tissue plasminogen activator (tPA) and underwent a mechanical thrombectomy. On hospital day three, she developed worsening of neurological symptoms, and a computed tomography (CT) angiogram revealed vasospasm in the region of the left middle cerebral artery (MCA), which subsequently resulted in nimodipine therapy. Furthermore, her hospital course was complicated by persistent hypotension, and with our concern for vasospasm that was noted in the CT angiogram instead of guideline-directed therapy for heart failure, digoxin was given to control heart rate and to improve cardiac output. Ultimately, her neurological symptoms improved, and she was discharged on hospital day 10. This case highlights the combination of rare presentations - postpartum cardiomyopathy, ischemic stroke, and reversible cerebral vasospasms, which suggests that the time and size of the stroke are of the essence in terms of promptness of aggressive treatment.
