Transposition corrigée des gros vaisseaux
La (ou L-TGV) se définit comme une double discordance. une discordance ventriculo-artérielle : l'aorte naît du ventricule droit et l'artère pulmonaire du ventricule gauche. Cette anomalie serait rapidement létale si elle n'était pas corrigée par une discordance auriculo-ventriculaire : les oreillettes droite et gauche sont en position normale. Il n'y a donc pas de shunt (sauf autre malformation associée) ; ce n'est donc pas une maladie bleue contrairement à la forme non corrigée de transposition des gros vaisseaux.
Dextro-Transposition of the great arteries
dextro-Transposition of the great arteries (d-Transposition of the great arteries, dextro-TGA, or d-TGA) is a potentially life-threatening birth defect in the large arteries of the heart. The primary arteries (the aorta and the pulmonary artery) are transposed. It is called a cyanotic congenital heart defect (CHD) because the newborn infant turns blue from lack of oxygen. In segmental analysis, this condition is described as ventriculoarterial discordance with atrioventricular concordance, or just ventriculoarterial discordance.
Cardiopathie congénitale
Les cardiopathies congénitales sont des malformations du cœur survenant au cours de sa formation, pendant la vie intra-utérine. Le terme « congénital » (littéralement « né avec ») est à distinguer du qualificatif « héréditaire » (« ce dont on hérite », ce qui est transmis par les ascendants). Une malformation congénitale, en particulier cardiaque, n'est pas obligatoirement héréditaire et peut correspondre à un accident isolé et qui ne se reproduira pas.
Acyanotic heart defect
An acyanotic heart defect, is a class of congenital heart defects. In these, blood is shunted (flows) from the left side of the heart to the right side of the heart, most often due to a structural defect (hole) in the interventricular septum. People often retain normal levels of oxyhemoglobin saturation in systemic circulation. This term is outdated, because a person with an acyanotic heart defect may show cyanosis (turn blue due to insufficient oxygen in the blood).
Arterial switch operation
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully. It was the first method of d-TGA repair to be attempted, but the last to be put into regular use because of technological limitations at the time of its conception.
Truncus arteriosus
The truncus arteriosus is a structure that is present during embryonic development. It is an arterial trunk that originates from both ventricles of the heart that later divides into the aorta and the pulmonary trunk. Heart development The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum. The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk. The caudal end of the bulbus cordis gives rise to the smooth parts (outflow tract) of the left and right ventricles (aortic vestibule & conus arteriosus respectively).
Persistance du canal artériel
La persistance du canal artériel est un état pathologique résultant de l’absence de fermeture physiologique du canal artériel à la naissance. Ce canal est un des dispositifs de la circulation sanguine fœtale ; il joint l’aorte et l’artère pulmonaire. La présence du canal artériel étant normale chez le fœtus, il est impossible de prévoir cette anomalie avant la naissance. À la naissance, le canal artériel persistant se transforme en un shunt artério-veineux laissant passer du sang de l’aorte vers l’artère pulmonaire.
Senning procedure
The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958. This procedure, a form of atrial switch, was developed and first performed by Senning in 1957 as a treatment for d-TGA (dextro-Transposition of the great arteries) before improvements in cardiopulmonary bypass made more curative surgical techniques feasible.
Veine cave
In anatomy, the venae cavae (ˈviːni_ˈkeɪvi; : vena cava ˈviːnə_ˈkeɪvə; ) are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium. They are located slightly off-center, toward the right side of the body. The right atrium receives deoxygenated blood through coronary sinus and two large veins called venae cavae.
Pulmonic stenosis
Pulmonic stenosis, is a dynamic or fixed obstruction of flow from the right ventricle of the heart to the pulmonary artery. It is usually first diagnosed in childhood. Pulmonic stenosis is usually due to isolated valvular obstruction (pulmonary valve stenosis), but it may be due to subvalvular or supravalvular obstruction, such as infundibular stenosis. It may occur in association with other congenital heart defects as part of more complicated syndromes (for example, tetralogy of Fallot).
