Timeframe: Day 1 (baseline) and Day 5 (follow-up)

Population: n= 4 to 5 for some measures

Evaluate the effect of udenafil on pharmacodynamic (PD) outcomes including: exercise capacity, vascular function, and echocardiographic measures of myocardial performance (MPI). The outcome measures (OM) are a difference between baseline (BL) and follow-up (FU, Day-5) \[OM = FU-BL\]. Endothelial pulse amplitude tonometry (Endo-PAT) is a technique for the non-invasive assessment of peripheral vascular function. In adults, Endo-PAT has been demonstrated to identify those with coronary artery dysfunction and to correlate with brachial artery reactivity testing. Endo-PAT use in children has been more limited, but has shown excellent reproducibility. Reactive hyperemia index (RHI), a measure of the hyperemic response adjusted for baseline blood flow, is a measure of vascular function. A higher value denotes better, or more healthy, vascular (endothelial) function. The data represents a change in the index value so there is no minimum or maximum value that can be represented on a scale.

SECONDARY outcome

Timeframe: Day 1 (baseline) and Day 5 (follow-up)

Population: n= 4 to 5 for some measures

The outcome measures (OM) are a difference between baseline (BL) and follow-up (FU, Day-5). Change in the MPI from baseline to Day 5 is determined by velocities from blood pool Doppler of the inflow and outflow tract of the dominant ventricle. The measure is the ratio of the sum of isovolumetric contraction time and isovolumetric relaxation time, divided by ventricular ejection time. A lower value is consistent with a more efficient ventricle (better function). A value of zero indicates that there is no isovolumetric contraction or relaxation and, while physiologically implausible, would be consistent with a perfectly efficient ventricle. In general, a decrease in the MPI corresponds to more efficient (better) ventricular function, while an increase in MPI corresponds to less efficient (worse) ventricular function. The data represents a change in the index value so there is no minimum or maximum value that can be represented on a scale.
