2-year-old girl with discordant criss-cross heart and atrioventricular nodal reentrant tachycardia (AVNRT)
Ablation
Successful ablation
This case report demonstrates the feasibility of successful AVNRT ablation in a very young patient with a rare discordant criss-cross heart.
Criss-cross heart is an extremely rare congenital heart defect defined as the crossing of the long axis of the atrioventricular (AV) valve. It was first described by Lev and Rowlatt in 1961,1 and the term “criss-cross heart” was initially coined by Anderson et al in 1972.2 According to the AV connection, criss-cross heart can be categorized into two types: concordant and discordant. In the concordant type, the inflowing blood streams from the right atrium (RA) to the right ventricle (RV) and from the left atrium (LA) to the left ventricle (LV) intersect.
