Detection of Pulmonic and Tricuspid Valvular Regurgitation by Means of Indicator Solutions
Why the study?
Does the injection of indicator solutions (cardiogreen and radioactive krypton) allow for the direct demonstration of reverse flow in patients with suspected pulmonic and tricuspid valvular regurgitation?
Population
Patients with suspected pulmonic and tricuspid valvular regurgitation

Implication
May enable in vivo detection of right-sided regurgitation; leaves open its diagnostic role versus modern imaging.
Structured PICO
Does the injection of indicator solutions (cardiogreen and radioactive krypton) allow for the direct demonstration of reverse flow in patients with suspected pulmonic and tricuspid valvular regurgitation?
P
Population
Patients with suspected pulmonic and tricuspid valvular regurgitation
I
Intervention
Injection of indicator solutions (cardiogreen and radioactive krypton [Kr 85]) into a distal chamber
O
Outcome
Detection of reverse flow across pulmonic and tricuspid valves (presence of cardiogreen and Kr 85 in the right atrium or right ventricle)surrogate
Indicator solutions such as cardiogreen and radioactive krypton can be used to directly demonstrate reverse flow across pulmonic and tricuspid valves in vivo.
