TVR was defined as any clinically driven repeat percutaneous intervention of the target vessel or bypass surgery of the target vessel. Clinically-driven revascularizations were those in which the patient has a positive functional study, ischemic ECG changes at rest in a distribution consistent with the target vessel, or ischemic symptoms, and an in-lesion diameter stenosis being greater than or equal to 50 percent measured by QCA.

SECONDARY outcome

Timeframe: At post-procedure

Population: Number of participants who had Stent Obstruction Volume data at post-procedure

Stent obstruction Volume equals 100 \* \[1-(lumen volume/baseline stent volume)\]; usually this is equal to zero at baseline, since the stent is freshly implanted and no obstruction is expected
