Measure
Tadalafil
Tadalafil: Active drug will be encapsulated to look identical to the placebo pill. Subjects will take a single oral dose of tadalafil once daily from the time of randomization until the surgical date (\~4 weeks). Subjects will begin by taking 20 mg (1 pill) daily for 3 days before having the dose increased to 40 mg (2 pills) once daily. If the increase to 40mg daily is not tolerated, then the dose will be decreased back to 20mg daily.
Placebo
Placebo: The placebo pill will be encapsulated to look identical to the active drug pill. Subjects will take a single oral dose of placebo once daily from the time of randomization until the surgical date (\~4 weeks). Subjects will begin by taking 1 pill daily for 3 days before having the dose increased to 2 pills once daily. If the increase to 2 pills daily is not tolerated, then the dose will be decreased back to 1 pill daily.

PRIMARY outcome

Timeframe: Baseline and 4 weeks

Population: We designed a different pilot trial based on data obtained after this study started - the 2 studies were too overlapping to continue both. We stopped this study after only 1 patient (assigned to tadalafil) was enrolled.

KCCQ overall summary score is reported. Scale is 0-100 (higher value is better).
