Peripartum cardiomyopathy presenting as a cardiac arrest at induction of anaesthesia for emergency Caesarean section

Abstract

Peripartum cardiomyopathy is defined as the onset of acute heart failure without demonstrable cause in the last trimester of pregnancy or within the first 6 months after delivery. It occurs in about 1 in 4000 deliveries and is often unrecognized as symptoms of normal pregnancy commonly mimic those of mild heart failure. We describe a previously asymptomatic patient who presented with a cardiac arrest at induction of general anaesthesia for emergency Caesarean section and subsequently developed acute heart failure. This case is unique both in its mode of presentation and the total absence of antecedent symptoms or signs of cardiac disease.
