EFFECTIVE CORRECTION OF THE COMMON ATRIOVENTRICULAR CANAL WITH TETRALOGY OF FALLOT AND HYPOPLASIA OF THE RIGHT VENTRICLE IN A CHILD

Abstract

The paper presents a description of a case of successful one and a half ventricular correction of a complex congenital cardiac anomalies, including the common atrioventricular canal, tetralogy of Fallot, and hypoplasia of the right ventricle in a child (2 year and 4 months). Ararecongenitalanomalycharacterized by acombinationof intracardiac defects, required an innovative surgical approach, the exclusivity of this clinical case has determined. The surgical strategy of complete atrioventricular canal defect is determined by a number of factors. One of the most important is balance between right and left ventricular outputs. The balanced type with adequate development of the ventricles involves the biventricular repair performance. Unbalancedatrioventricular canal defects includea hypoplastic ventricle. Reconstructive surgeryfor onehypoplasticventricle is oriented towards the degree of hypoplasia. In particular, a mild right ventricular hypoplasia allows perfoming biventricular radical operation while a severe degree suggests univentricular repair. In case of borderline, moderate degree of hypoplastic right ventricle the one and half ventricle repair can be carried out. Another important point is the presence of concomitant pulmonic stenosis required the choice of optimal method and material for reconstruction which is not always obvious and often it is the subject of debates. This report presents a description of the diagnostic stages with an emphasis on determining the type of balance of the common atrioventricular canal, the degree of hypoplasia of the right ventricle, the approach to choosing the optimal method for correcting the defect in general and the material for reconstructing the outflow pathway from the right ventricle in particular, as well as the subsequent successful correction of congenital multicomponent cardiac abnormalities in a young patient.
