OBJECTIVE: To explore atrioventricular connection and atrioventricular segmental situs in patients with crisscross heart (CCH) and to evaluate the diagnostic value of echocardiography for this anomaly.
METHODS: Ten consecutive patients with crisscross heart were enrolled into this retrospective study. Their echocardiographic data were analyzed and compared with the results of X-ray angiocardiography and 64-slice multi-detector row computed tomography (MDCT) or MRI.
RESULTS: The crossing of atrioventricular valves could be seen in each case by scanning in a subxiphoid or apical 4-chamber view. Both the positive rate and the specificity were 100%. Horizontal ventricular septum was in 9 cases and vertical (sagittal) ventricular septum in 1 case. The segmental set of 8 patients with concordant atrioventricular connection was {S. D. L} in 5 cases, {S. D. D} 1 case, {S. D. S} 1 case and {S. L. D} 1 case. The segmental set of 1 case with discordant atrioventricular connection was {I. D. D} and another 1 case with ambiguous atrioventricular connection was {A. L. L}. In 1 case, the atrioventricular connection was inconsistent with the atrioventricular segmental situs. Ventriculoarterial connections were concordant in 1, DORV in 6, TGA in 2 and C-TGA in 1.
CONCLUSION: Echocardiography is proven quite helpful in diagnosis of CCH, and continuous sweeps in subxiphoid long-axis plane or apical 4-chamber view play a key role. Both the atrioventricular connection and the atrioventricular segmental situs are complicated so that they are not always concordance with each other. It is necessary to account for separately.
