Pregnancy is a physiological situation that produces transient preload and afterload changes. The heart is subjected to reversible morphological remodelings and hemodynamic and functional adaptations. The characterization and understanding of maternal cardiac function during normal pregnancy by echocardiography 2D is of clinical importance for the opportune recognition of cardiac pathology. This study aims to investigate pregnancy-induced changes in ventricular strain in healthy pregnant women by echocardiography.
Study Type
OBSERVATIONAL
Enrollment
50
In this echocardiographic imaging acquisition protocol, the pregnancy patients, are colocated in the left lateral decubitus position on a clinical bed with the left arm flex and the hand behind the head. All the echocardiographic measurements are taken by the examiner in this position.
