Abstract

1. The authors present 80 cases of tricuspid atresia of the Children's Cardiology Service of the Instituto Nacional de Cardiología de México. They propose their own classification based on the position of the visceral suits and of the great arteries and the possible existance of a persistent truncus arteriosus. 2. The requirements that should be fulfiled to establish an anatomic and hemodynamic diagnosis are determined; and the need to know in detail the anatomy of the right ventricle; of its exit chamber, of the pulmonary valve and of the pulmonary truncus is emphasized; as well as the measures in the auricles and the left ventricle. 3. They insist upon the need, when the pulmonar arterial pressure cannot be measured directly, to introduce a catheter in a pulmonar vein, because the pressures obtained are quite similar to the pressure in the pulmonar arterial territory. 4. The fundamental data of the anatomic and hemodynamic study are discussed and illustrated. They confirm the close relation that exists between the diameter of the exit chamber of the right ventricle and of the valvular ring, the pulmonary truncus and its branches. 5. In all cases of tricuspid atresia with AQRS deviated to the right and downwards in the frontal...Continue Reading
