Clinical trials: Ventricular Function
Echocardiography, Pregnancy Related Conditions, Unspecified, First Trimester
Echocardiographic Assessment of Ventricular Strain During a Healthy Pregnancy in the First, Second, and Third Trimester.
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.
