Purpose of review Pregnancy and the peripartum period represent a physiological burden for the cardiac patient that can worsen even moderate degrees of cardiac disease. Valvular stenotic diseases, congenital cardiac disease, and coronary insufficiency are relatively frequent in pregnant patients. Since considerable variability exists in the cardiovascular changes and responses to labour among different cardiac diseases and their functional status, recommendations for anaesthetic management are based on reported clinical experience and pathophysiological concepts. Recent findings Neuroaxial blockade reduces or even abolishes the cardiovascular stress response to pain, mitigates Valsalva effects by decreasing the pushing reflex, and allows the adaptation of analgesia or anaesthesia to labour stage and delivery. Sympathetic blockade caused by standard neuroaxial techniques, however, reduces systemic vascular resistance and cardiac preload followed by reflex tachycardia. Recent development of neuroaxial techniques with spinal opiates for the first stage of labour, carefully titrated segmental epidural analgesia with opiates combined with low concentrations of local anaesthetic for the second stage, and even low spinal anaesthesia for vaginal instrumental delivery, have all been used with good results in patients with severe cardiac disease. Summary Only Tetralogy of Fallot, primary pulmonary hypertension, idiopathic hypertrophic subaortic stenosis, and anticoagulation are considered relative or absolute contraindications for neuroaxial techniques, though slow segmental blockade of dermatomes may offer an alternative. For Caesarean section, single shot spinal anaesthesia is not recommended in moderate or severe heart disease. Adequate cardiovascular invasive monitoring is essential and should be administered and maintained in the postpartum period with the same criteria that reduce morbidity and mortality in cardiac patients undergoing general surgery.
