Invasive techniques however remain the mainstay of long-term management of complex critically ill obstetric patients. One area of non-invasive assessment warrents special mention. In non-pregnant patients echocardiographic assessment of pulmonary artery pressures are commonly accepted and generally valid. In the past three decades clinicians with extensive experience in the management of pregnant women with pulmonary hypertension have commonly noted significant discrepancies between non-invasive assessment of pulmonary artery pressures and actual pressures measured directly with right heart catheterization. In 2001 this observation was validated by Penny et al. who found that pulmonary artery pressures were commonly overestimated in pregnant women with suspected pulmonary hypertension 72 . Based upon this data and many years of clinical experience we recommend that any pregnant woman with elevated pulmonary artery pressures by echocardiogram have this diagnosis confirmed by invasive right heart catheterization before counseling and critical clinical decisions are initiated.
