Summary

Description
Deutsch: 1. Starr-Edwards Herzklappe, Stahlkugel

2. Starr-Edwards Herzklappe, Silikonkugel 3. Smeloff-Cutter Herzklappe, Silikonkugel

Zur Ermöglichung einer Röntgenfunktionsdiagnostik wurden die Silikonkugeln sind mit Bariumsulfat versetzt.

Die Ventile wurden mit der runden Ventilseite auf die Ventilebene des Herzens befestigt. Käfig und Ball ragten in das vom Herz fließende Gefäß (Aorta oder Lungenarterie).

Baut sich im Herzen ein ausreichender Druck auf, öffnet sich das Ventil in dem sich der Ball vom Herzen weg bewegt und das Blut fließt durch die runde, primäre Ventilöffnung am Ball vorbei in das Gefäß.
English: 1. Starr-Edwards Valve, Steel ball

2. Starr-Edwards Valve, Silicone Rubber Ball 3. Smeloff-Cutter Valve, Silicone Rubber Ball

In order to simplify x-ray functional diagnostics of the prosthetic cardiac valve the silicone rubber ball is impregnated with barium sulfate for radiopacity. The circular side of the valve is attached to the basis of the heart. Ball and cage reach into the vessel (aorta or pulmonary artery).

If the pressure in the heart builds up, the valve opens by movement of the ball away from the heart, the blood flows through the primary, circular opening of the valve and past the ball into the vessel.
