Implication
Supports echo interpretation during catheterization; hypothesis-generating for contrast validation without broader confirmation.
Key Points
- The aim is to identify ultrasound echoes from the left ventricle using intracardiac injections of indocyanine green.
- Intracardiac injections of indocyanine green and saline were performed via cardiac catheter.
- Echoes produced were assessed to determine their origin and clarity during diagnostic catheterization.
- Injected indocyanine green produced distinct ultrasound echoes in the left ventricle, outlining critical cardiac structures.
- The technique improved differentiation between left ventricular wall echoes and confusing intracavitary echoes.

Intervention
Intracardiac injections of indocyanine green and saline directly in the left ventricular cavity via a cardiac catheter
O
Outcome
Identification of ultrasound echoes originating from the left ventriclesurrogate
Intracardiac contrast injections validate the origin of left ventricular ultrasound echoes, improving the accuracy of echocardiographic measurements.
