Escalate
Chest pain, syncope, sustained arrhythmia, hypoxaemia, pulmonary oedema or sudden severe chest/back pain in pregnancy is not physiological: activate maternal emergency care with obstetric, cardiology, anaesthetic and critical-care teams and investigate without delaying necessary imaging.
Synopsis
Risk-stratify cardiovascular disease before and during pregnancy, recognise maternal emergencies and coordinate care through a Pregnancy Heart Team.
Assess known CVD before conception using mWHO 2.0 plus lesion-specific and individual factors.
Women with mWHO 2.0 class II-III or higher should be evaluated and managed by a Pregnancy Heart Team from pre-pregnancy through postpartum care.
mWHO 2.0 class IV indicates extremely high maternal and fetal risk; provide expert shared decision-making and discuss alternatives to pregnancy, not coercive care.
Key red flags
Aortic syndrome
Abrupt severe chest/back pain, pulse deficit or neurological signs in an aortopathy is an emergency.
Investigation priorities
01
12-lead ECG and rhythm monitoringFirst step

FirstPre-pregnancy cardiovascular review
Known or suspected CVD, prior cardiotoxic therapy or important family/genetic cardiac history.
