Development of takotsubo cardiomyopathy with severe pulmonary edema before a cesarean section

Takotsubo cardiomyopathy in pregnancy: a case report and literature review

BACKGROUND

Takotsubo cardiomyopathy is rare in pregnancy and is characterized by left ventricular dysfunction with apical ballooning. This transient cardiac dysfunction may affect women of childbearing age in the antepartum, intrapartum or postpartum period. Most patients respond well to medical management with resolution of cardiac dysfunction within weeks.

CASE PRESENTATION

A 35-year-old female in her second pregnancy presented with severe preeclampsia at 31 weeks of gestation. She subsequently developed severe substernal chest pain and workup showed a stress induced cardiomyopathy prior to her delivery via caesarean section. She had full recovery of her cardiac function by 12 weeks postpartum after medical management.

CONCLUSIONS

Stress induced cardiomyopathy, though rare, should be considered after acute myocardial infarction has been ruled out in gravid females presenting with acute chest pain. Management should involve a multidisciplinary team. Cardiac function recovery is common within 4 weeks although some patients may require long term heart failure management.

Takotsubo cardiomyopathy after cesarean section: A case report and literature review

Takotsubo cardiomyopathy (TCM) is clinically identical to acute myocardial infarction. We report an unusual case of TCM and review similar cases in pregnant women. A young woman with no pre-existing cardiovascular risk factors suffered sudden dyspnea during a cesarean section. Electrocardiography (ECG) showed T-wave inversion. We observed acute lung edema and left ventricular systolic dysfunction on echocardiography. A cardiac catheterization diagnosed TCM. We reviewed 20 cases of TCM; 17 cases occurred during the post-partum period and three during pregnancy. Five of these cases had vaginal deliveries and the remaining cases had cesarean sections. Within the latter group, five cases appeared intraoperatively. With the exception of one patient with normal ECG results, all other patients progressed, with changes in ECG readings and elevation of cardiac enzyme serum levels. However, cardiac catheterization revealed that coronary arterial damage did not occur in any of the cases. After three months, each patient fully recovered.
