AOI - Aorteninsuffizienz/Aortenklappeninsuffienz - aortic insufficiency/aortic valve insufficiency

Aortenstenose, AOI = Aorteninsuffizienz, MI = Mi
tralinsuffizienz, TI = Trikuspidalinsuffizienz,
VSD = Ventrikelseptumdefekt, L-TGA = sogenannte korrigierte Transposition der großen
Arterien, LA = linker Vorhof, LV = linker Ventrikel, RV = rechter Ventrikel, LVOT = linksventrikulärer Ausflußtrakt)

Die BiAoV stellt die häufigste kongenitale kardiale Fehlbildung mit dem Risiko von Aortenklappenstenosen (AoS), -insuffizienzen (AoI) und Aneurysmata (Aneu) der Aorta dar. Kohortenuntersuchungen zur Inzidenz und Verlauf von BiAoV ohne initial relevante Aos, AoI und Aneu fehlen.

Aortic insufficiency is a heart valve disease in which the aortic valve does not close tightly. This leads to the backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (a chamber of the heart).

The VC appears to correlate with the effective surface regurgitation (ERO) very well. In addition, the VC is found to be of the afterload or diastolic function of the left ventricle. Independently this seems to be the severity of aortic valve insufficiency of a very good size.
A VC diameter> 6mm appears to have a serious, very good sensitivity and specificity Aoi.
