Implication

Diagnostic evaluation demonstrates rapid detection of right-to-left shunts in infants, indicating a sensitive and low-cost approach for routine pediatric catheterization.

Key Points

To assess the feasibility and diagnostic accuracy of using an arterial potentiometric platinum electrode to detect and localize right-to-left intracardiac shunts.
Injected hydrogen-saturated saline into the right heart chambers and monitored the aorta for dissolved hydrogen using an arterial potentiometric platinum electrode.
Localized shunt position through sequential indicator injections into different chambers of the heart.
Administered sodium ascorbate as an alternative indicator and as a control test to verify electrode responsiveness.
Dissolved hydrogen was detected in the aorta following right-heart injections exclusively in the presence of right-to-left shunts, as normal pulmonary circulation completely clears hydrogen.
The platinum electrode system achieved rapid, highly sensitive responses with low procedural cost and operational simplicity suitable for routine infant catheterizations.
