Various congenital or acquired valvular heart diseases (VHD) may be present in pregnant women, and may significantly increase the maternal and fetal risk associated with pregnancy. Pregnancy is associated with significant haemodynamic changes that may aggravate VHD, precipitate or exacerbate symptoms, and increase the risk of thrombo-embolic events. Cardiac imaging modalities, particularly echocardiography and cardiac magnetic resonance, are pivotal for the diagnosis and management of pregnant women with VHD. Valve lesions with a fixed cardiac output, such as severe mitral or aortic stenosis, are at greatest risk of decompensation, while regurgitant lesions are likely to be well tolerated, as the fall in vascular resistance compensates for the volume loading induced by pregnancy. Despite the increased risk, with appropriate cardiologic evaluation and treatment most pregnant women with VHD can successfully deliver healthy children. Women with moderate and high risk of complications during pregnancy should be evaluated in an expert center in VHD by a pregnancy multidisciplinary heart team.

Abstract
Various congenital or acquired valvular heart diseases (VHD) may be present in pregnant women, and may significantly increase the maternal and fetal risk associated with pregnancy. Pregnancy is associated with significant haemodynamic changes that may aggravate VHD, precipitate or exacerbate symptoms, and increase the risk of thrombo-embolic events. Cardiac imaging modalities, particularly echocardiography and cardiac magnetic resonance, are pivotal for the diagnosis and management of pregnant women with VHD. Valve lesions with a fixed cardiac output, such as severe mitral or aortic stenosis, are at greatest risk of decompensation, while regurgitant lesions are likely to be well tolerated, as the fall in vascular resistance compensates for the volume loading induced by pregnancy. Despite the increased risk, with appropriate cardiologic evaluation and treatment most pregnant women with VHD can successfully deliver healthy children. Women with moderate and high risk of complications during pregnancy should be evaluated in an expert center in VHD by a pregnancy multidisciplinary heart team.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
