BACKGROUND: Criss-cross is a rare congenital heart disease, of which the electrocardiographic characteristics are not precisely known for early diagnosis.
OBJECTIVE: To compare electrocardiographic and echocardiographic characteristics for the diagnosis of patients with criss-cross heart.
METHODS: A retrospective, comparative, cross-sectional study was carried out in two centers over 42 years. The age, sex, and 12‑lead basal electrocardiographic parameters were analyzed. In cases of dextrocardia, right-sided and posterior ECG were performed. Echocardiography was performed to obtain atrial situs, cardiac position, atrioventricular and ventricle arterial relationship, and associated cardiac defects. A descriptive analysis with measures of central tendency was done to assess the age of the population and proportions for the echocardiographic-electrocardiographic characteristics. A statistical analysis was used to find significant differences (p < 0.05) between the ECG and echocardiography groups.
RESULTS: Of the 21 patients studied, 14 (66%) were found with situs solitus, 10. (47.6%) with levocardia, 14 (66%) with atrio ventricular concordance, 13 (61.9%) with double outlet right ventricle and 17 (80.9%) with supero-inferior ventricles. The electrocardiogram predicted atrioventricular relationship in 20 cases (95.2%) (p < 0.01) and supero-inferior ventricles in 17 (81%), 15 (71.4%) had a superior QRS axis (82%) (p 0.02). Atrial and ventricular enlargement in the electrocardiogram correlated (p = 0.05) with associated defects in 16 cases (76.1%).
CONCLUSIONS: The electrocardiographic analysis of these patients allows us to visualize the situs, position of the cardiac chambers, and associated defects in patients with criss-cross heart. It is useful for the diagnostic orientation of the echocardiographer and therefore contributes initially to the echocardiographic study.
