Abstract
Description
Durch gezielte Plazierung eines Schneidesystems mit Hilfe einer Ultraschallsonde werden bei Patienten mit Mitralstenose die Kommissuren der Mitralklappe getrennt, um eine Vergrößerung der Klappenöffnungsfläche zu erreichen.By placing a cutting system with the help of an ultrasound probe Patients with mitral stenosis separated the commissures of the mitral valve to enlarge the To reach the flap opening area.
Unkontrolliertes Einreißen der Kommissuren und der Mitralsegel mit daraus resultierender Mitralinsuffizienz werden vermieden. Restenosierungen infolge alleiniger Dehnung des Klappenringes treten nicht auf.Uncontrolled tearing of the commissures and the mitral sail with the resultant Mitral regurgitation is avoided. Residual doses due to the sole stretching of the Flap ring do not occur.
- a) Übliches transvenöses, transseptales Vorgehen bis zur Mitralklappe.a) Usual transvenous, transseptal procedure up to the mitral valve.
-
b) Mit Hilfe des Führungsdrahtes wird der Katheter mit seinem Ballonanteil bis in den linken
Ventrikel vorgeschoben.
Nach Füllen des Ballons mit Kontrastmittels Fixierung im Mitralklappenring.b) With the help of the guide wire, the catheter with its balloon portion is advanced into the left ventricle.
After filling the balloon with contrast medium, fixation in the mitral valve ring. - c) Nach Einführen der Ultraschallsonde werden die Kommissuren der Mitralklappe dargestellt.c) After insertion of the ultrasound probe, the commissures of the mitral valve are shown.
- d) Durch eine Markierung an der Ultraschallsonde ist das gezielte Positionieren des Schneidesystems hinter der Mitralklappe an der Kommissur möglich.d) A marking on the ultrasound probe enables the targeted positioning of the Cutting system behind the mitral valve on the commissure possible.
- e) Durch Herausfahren des Haltedrahtes wird die spätere Schnittgröße bestimmt. Der Schnitt wird durch Zug am Schneidedraht durchgeführt.e) The later cutting size is determined by pulling out the holding wire. The cut will performed by pulling on the cutting wire.
- f) Alternativ ist der Schnitt durch ein Messer- oder Thermosystem denkbar.f) Alternatively, a cut through a knife or thermal system is conceivable.
- g) Kontrolle des Ergebnisses durch Ultraschall, evtl. auch mit Dopplermessung.g) Control of the result by ultrasound, possibly also with Doppler measurement.
9 French Kathetersystem mit 4 Kanälen9 French catheter system with 4 channels
- a) Instrumentierkanala) Instrument channel
- b) Kanal für Ultraschallsondeb) Channel for ultrasound probe
- c) Kanal für den Führungsdraht und Kontrastmittelc) Channel for the guidewire and contrast medium
-
d) Kanal zum Ballonsystem
12,5 Mhz Ultraschallsonded) Channel to the balloon system
12.5 Mhz ultrasonic probe
