When there are signs of hemodynamic compromise, careful fetal monitoring is needed. Clinical and ultrasound examinations can assess fetal growth and amniotic fluid volume. Other tests that may be required are cardiotocography to measure fetal heart rate, color doppler flow studies to measure fetal and maternal placental blood flow, fetal blood sampling to detect low oxygen content. If heart failure develops, the principle treatments remain the same, with dogoxin and diuretics being the cornerstones of therapy. Arrhythmias and anemia are treated.
Hospitalization is recommended while things get under control.
Many studies have been done in the last 10 years. Early detection and treatment of cardiac arrhythmias if present, is essential to preventing complications. The basic factor in all the studies is that careful cardiac and obstetric management results in good maternal and fetal outcomes. Mitral valve prolapse, without significant mitral regurgitation during pregnancy does not appear to be of significant risk for developing complications.
