Discordant atrioventricular connection with double outlet right ventricle is a rare complicated congenital heart defect (CHD) requiring accurate diagnosis and appropriate correction. Magnetic resonance imaging (MRI) and multiple spiral computed tomography (MSCT) were used to assess long-term outcomes of the «classical» repair of the double outlet right ventricle in a patient presenting with discordant atrioventricular connection.

Using a modified segmental approach provided all necessary anatomical evidence concerning the condition of the heart, major vessels, and an extracardiac pulmonary valve-containing conduit. MSCT made it possible to evaluate the degree of calcinosis and stenosis of the conduit and to visualize the coronary arteries. MRI was employed to assess the pressure gradient at the level of stenosis of the conduit, the relationship between the pulmonary and systemic circulation, transvalvular regurgitation, and ventricular contractility.

Comprehensive use of present-day tomographic methods of imaging made it possible to obtain complete anatomical and functional information about the condition of the heart, vessels, extracardiac vascular transplant, as well as to reveal complications and determine the indications for a repeat operative intervention.

KEY WORDS: discordant atrioventricular connections, corrected transposition of major vessels, double outlet right ventricle, MRI, MSCT.
