Echocardiography in Heterotaxy Syndrome

The important anatomic aspects of heterotaxy syndrome can be diagnosed by Doppler echocardiography in the newborn and infant. An organized approach and an understanding of asplenia (right atrial isomerism) and polysplenia (left atrial isomerism) are integral to the echocardiographic study. Detailed and precise depiction of the anatomy is the mainstay for staging subsequent medical and surgical management.
