IPCCC Code: 01.01.03, 01.03.00, 07.21.00, 07.09.01
 

AEPC Code:    

Congenitally corrected transposition of great arteries (discordant AV & VA connections), Usual atrial arrangement (atrial situs solitus), Intact ventricular septum, Left ventricular outflow tract obstruction

EACTS-STS Code:    

Discordant AV connections with situs solitus, Discordant VA connection (Congenitally corrected transposition) (usually {SLL}), IVS and LVOTO

Definition:  NA

Common Synonyms: NA

This four chamber view demonstrates the discordant atrioventricular connections associated with congenitally corrected transposition. The right-sided, morphologically right atrium (mRA) is connected to the right-sided morphologically left ventricle (mLV) with the mitral valve (MV) in the inlet portion. On the left side, the morphologically left atrium (mLA) is connected to the morphologically right ventricle (mRV). The tricuspid valve (TV) is in its inlet portion. There is usual atrial arrangement. Note the reverse off-setting of the atrioventricular valves (red lines) as well as the intact ventricular septum. Although not imaged, this heart also had outflow tract obstruction from the right-sided morphologically left ventricle (mLV) to the pulmonary trunk. (ICV-inferior caval vein, OF-oval fossa)
