Pulmonary oedema in two parturients with hypertrophic obstructive cardiomyopathy (HOCM).

Two patients with hypertrophic obstructive cardiomyopathy (HOCM) presented for delivery. The first had a repeat Caesarean section with general anaesthesia and the second gave birth vaginally with epidural analgesia. Both patients developed pulmonary oedema in the peripartum period. These cases highlight the delicate fluid requirements of the pregnant patient with HOCM. The fluid management of the parturient is discussed with particular emphasis on the pathophysiology of HOCM. The indications for invasive monitoring are presented.
