Peripartum cardiomyopathy. Perioperative anaesthesiological management of a rare complication of pregnancy

Abstract

Peripartum cardiomyopathy is a rare disorder with an incidence from 1:3,000 to 1:15,000 live births and thus not often described in the anaesthesiology literature. The etiology of this disease is still not known but the symptoms are similar to idiopathic dilated cardiomyopathy. Echocardiographic findings show a dilatation of the left ventricle in addition to abnormal wall motion with a severe reduction of the cardiac function. Despite the rarity of this disorder, the anaesthesiologist or ICU physician should consider peripartal cardiomyopathy as a differential diagnosis to ensure an adequate perioperative management. There seems to be an increased incidence in pregnant women who are elderly (age >30 years),who have a history of gestosis/hypertension,have a gemini pregnancy or are of black origin. The prognosis depends on the recovery of the left ventricular contractility within the first 6 months after onset of the disease. The mortality rate is reported to vary between 25% and 50%. Heart transplantation is regarded as the last resort which has successfully been performed with several patients. This case describes the perioperative management of a 32-year-old women with peripartum cardiomyopathy.
