尽管诊断心脏病学技术不断改进，超声心动图仍然是对患有心脏病或疑似心脏异常的孕妇进行无创心血管评估的基石。与瓣膜通畅或跨瓣膜血流模式变化相关的妊娠期可逆生理性心脏重塑可以通过定量脉冲和连续多普勒以及定性彩色多普勒技术的互补使用来适当评估。这些技术还有助于更好地理解妊娠期间固定瓣膜狭窄的血流动力学后果的病理生理学，以及妊娠期间发生的可变负荷条件导致的梯度的不稳定性质。最近和特定的临床应用领域，包括心输出量估计、对比超声心动图最大限度地减少心导管插入术期间的放射检查以及经食管超声心动图用于选择适合经皮导管瓣膜切开术的二尖瓣狭窄患者，说明了这种多功能方法在怀孕期间的广泛功能。
Despite continuous improvements in diagnostic cardiology techniques, echocardiography remains the cornerstone for noninvasive cardiovascular assessment of the pregnant woman with heart disease or suspected cardiac abnormality. Reversible physiological cardiac remodeling of pregnancy associated with changes in valve patency or transvalvular flow pattern, can be suitably assessed by the complementary use of quantitative pulsed- and continuous Doppler and qualitative color Doppler technology. These techniques are also useful for a better understanding of the pathophysiology of the hemodynamic consequences of fixed valve stenosis during pregnancy with respect to the labile nature of gradients resulting from variable loading conditions as occurs during pregnancy. Recent and specific areas of clinical use including cardiac output estimation, contrast echocardiography minimizing radioscopy during cardiac catheterization and transesophageal echocardiography for selection of patients with mitral stenosis suitable for percutaneous catheter valvotomy illustrate the large spectrum of capabilities of this versatile method during pregnancy.
