The parturient with coronary heart disease.
Cardiac disease is one of the leading indirect causes of maternal mortality in the UK, exceeding numbers of direct deaths from thromboembolism and hypertension combined. Over one year in our unit we managed six women with coronary heart disease. In this series five women had stable coronary heart disease. Three delivered electively by caesarean section under combined spinal-epidural anaesthesia, a further two women had spontaneous vaginal deliveries, one planned under epidural analgesia, the second unplanned after a rapid labour. The sixth woman had unstable angina requiring percutaneous coronary intervention in the 28th week of pregnancy and went on to deliver by caesarean section under general anaesthesia. Regional anaesthesia was avoided in this case because of antiplatelet and anticoagulant medication. There is a lack of level-one evidence to direct the management of these women. Clinical decisions were directed by guidelines for the perioperative management of patients with cardiac disease in non-cardiac surgery and the management of all cardiac disease in the obstetric population. A multi-disciplinary approach was taken, with a collaborative plan made for each pregnancy and delivery. A thorough clinical history and examination together with transthoracic echocardiography allows risk stratification of women with coronary heart disease at risk of peripartum cardiac events. Further investigation specific to each woman's management can then be undertaken.
