title: Prenatal Diagnosis of the Criss-Cross Heart.
abstract: We sought to describe the prenatal features and postnatal outcomes of the "criss-cross heart" (CCH) with crossing atrioventricular connections as encountered in 5 cases and to review the literature regarding fetal diagnoses of this lesion. We reviewed the clinical history and fetal echocardiograms of 5 patients with a diagnosis of CCH encountered in our institution from 2010 to 2015. Affected pregnancies were identified through the University of Alberta fetal cardiology database. Fetal and postnatal echocardiograms, prenatal and postnatal clinical records, autopsy, and surgical reports were reviewed. Over the past 5 years, major fetal congenital heart disease was identified in 448 pregnancies in the province of Alberta. Of these, 5 had CCH. All 5 were referred for suspected congenital heart disease, and none had significant extracardiac pathology. Detailed methodical 2-dimensional and color Doppler fetal echocardiography defined the complex diagnoses that were subsequently confirmed postnatally (n = 4) and at fetal autopsy (n = 1). Prenatal diagnosis correctly predicted postnatal presentation and outcomes in 1 with double outlet right ventricle and coarctation, 2 presenting with complete (D) transposition of the great arteries physiology, and 1 presenting as corrected (L) transposition. Three required single ventricle palliation and 1 underwent an arterial switch procedure. In conclusion, detailed evaluation of fetal CCH can result in correct anatomical and pathophysiological diagnoses. It demands a full understanding of the anatomy and pathophysiology to predict accurately the presentation at birth for accurate counseling and planning perinatal management.
