Abstract:
A newborn with prenatally diagnosed dysplasia of both atrioventricular valves presented after birth with signs and symptoms of low cardiac output, severe regurgitation of both mitral and tricuspid valves. This combination is as rare as challenging, since it regards both the timing and management of this complex cardiac malformation. We report an early surgical repair of both atrioventricular valves in a symptomatic newborn, which improved his clinical status and, so far, delayed valve replacement.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
