Crisscross heart with situs invesus in pregnancy: A rare case report and literature review

Crisscross heart(CCH) is a rare congenital anomaly. CCH is always with rare complex congenital heart malformations, and for this reason it is difficult to diagnose. We present an asymptomatic 29-year-old pregant woman with history of cardiac murmur at 28 weeks of gestation. Transthoracic echocardiography revealed a CCH with situs inversus, concordant atrioventricular, double outlet right ventricle, ventricular septum defect and pulmonary stenosis. The anomalies were demonstrated by two-dimensional echocardiography and confirmed by color Doppler imaging. The patient was stable and did not require surgical interventions. She underwent successful term vaginal delivery without complication and her baby had a normal heart. Patients with CCHs can be diagnosed by a careful, systematic study with two-dimensional and Doppler echocardiography to identify the ventricular morphology and position, determine the sequence of connections and spatial relationships of the cardiac chambers and identify other abnormalities.
