Effects

By the interruption of the blood river in the Aorta the lower body half is not supplied with blood. So that the supply of the body, in particular the liver, must likewise exist which kidneys and the gastro-intestinal tract can take place, another heart error. With enormous pressure the left Herzkammer pumps against the interruption and the discharge opening is then e.g. the VSD. The lung is flooded and the blood arrives then rapidly again in the left Herzkammer. Both the lung and the heart are not in a constant stress condition and it come to the overloading of these are available finally VSD, but the cycle only on the vorgeburtlich necessary Ductus arteriosus dependent, the children come into a shock condition if this connection in the first life hours, - meet or - weeks lock. They can decease then fast if are not in time acted.

Diagnostics

• The clinical investigation is nonspecific and not clear. The blood pressure at the legs can be lower than at the arms.
• the Echokardiografie normally shows all false formations
• when X-raying one sees the increased blood flow through the lung and usually an increased heart
• without a heart catheter investigation can be done in clear cases. Nevertheless the indication is to be placed because of the other false formations and regarding the operation

Therapy

The therapy exists first in the gift of Prostaglandin, a medicine, which can keep or again open the Ductus open arteriosus. The operation must take place then as fast as possible.

• Zweitiges procedure with the operation: The connection of the interrupted aortic arch is created, depending upon development of the interruption, either by connection of the existing Aortenteile or over a Kunststoffprohese (Patch). Additionally with a small band the Lungenarterie in its discharge is limited (Pulmonales Banding). This operation can, as are accomplished with the Aortenisthmusstenose without employment the heart lung machine and by this relatively "“small interference"” can the child are stabilized. In a second operation the still existing heart errors must be operated at a later time. The plastic prosthesis grows not along and must be replaced according to the development of the child.
• an in-early procedure with the operation is accomplished likewise today in view of improved intensive-medical support and technology. With the help of the heart lung machine all false formations are corrected with an operation.

Results

Altogether the results are equivalent good both after in-early and after the zweiteitigen procedure. Due to the complex heart error is (2004) however world-wide still a number of deaths from approx. 30 to 50%. After the correction (as with a Aortenisthmusstenose) in the operation places again narrowings can form, which make renewed operations or Ballondilatationen with the heart catheter or a Stentimplantation necessary. With approximately 50% of the patients must be counted in the course of the following 10 years on a subsequent treatment. A lifelong follow-up assistance further is necessary, just as the adherence to the Endokarditisprophylaxe.

Adult with interrupted aortic arch

There are young people and adults with this false formation. With them the Ductus locked arteriosus so slowly that evasion cycles could form. Humans concerned have same symptoms as such with a high-grade Aortenisthmusstenose.
