Case Reports
Prolonged Cardiac Dysfunction After Intraparenchymal Hemorrhage and Neurogenic Stunned Myocardium.
Cardiac dysfunction occurring secondary to neurologic disease, termed neurogenic stunned myocardium, is an incompletely understood phenomenon that has been described after several distinct neurologic processes. We present a case of neurogenic stunned myocardium, discovered intraoperatively after anesthetic induction, in a patient who presented to our operating room with a recent intraparenchymal hemorrhage. We discuss the longitudinal cardiac functional course after neurogenic stunned myocardium. Finally, we discuss the pathophysiology of neurogenic stunned myocardium, as well as its implications for anesthesiologists caring for neurosurgical patients.

Neurogenic stunned myocardium is a significant complication of subarachnoid hemorrhage. Diagnosis of neurogenic stunned myocardium is complicated by variable presentation. ⋯ Echocardiography showed hypokinesis of the basal left ventricular segments and normal contraction of the apical left ventricular segments consistent with a variant form of neurogenic stunned myocardium. We describe characteristics and outcomes of neurogenic stunned myocardium in this young patient with arteriovenous malformation-associated aneurysmal subarachnoid hemorrhage.

Case Reports
Reverse Apical Ballooning Echocardiographic Pattern in Eclampsia-Related Cardiomyopathy.
The diagnosis of heart failure during pregnancy has important management implications for the parturient and her fetus. A 19-year-old primigravida developed eclampsia at 29 weeks' gestation. Echocardiography demonstrated normal left ventricular size and ejection fraction of 35% with reverse apical ballooning (reverse takotsubo pattern). ⋯ Follow-up echocardiography 4 weeks after delivery showed complete normalization of her ejection fraction (56%). This case of eclampsia-related stress-induced cardiomyopathy is a distinct entity from peripartum cardiomyopathy. Using echocardiography, the diagnoses should be differentiated with appropriate management and counseling.
