Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The Everolimus-Eluting Coronary Stent System (PROMUS Element) is a metal tube coated with the drug Everolimus. One stent will be permanently implanted in the patient via use of a catheter inserted into the vasculature. The drug dosage depends on the size of the stent and varies from 57 micrograms (2.25x12mm stent) to 242 micrograms (4.0x38mm stent) and this drug is gradually released into the surrounding arterial tissue for approximately 3 months following stent implantation. Stent size is selected by the investigator based on vessel diameter and length. Typically stent diameter is selected to be slightly larger than the vessel diameter (ie a 3.0mm stent would be used to treat a 2.8mm vessel). Typically stent length is selected so that the stent is 2-4mm longer than the lesion length (ie a 28mm stent would be used to treat a 22mm lesion)

Outcomes
Primary outcome [1] 240566 0
12-month target lesion failure (TLF) rate, defined as any ischaemia-driven revascularisation of the target lesion (TLR), Myocardial Infarction (MI) (Q-wave and non-Qwave) related to the target vessel, or cardiac death related to the target vessel
Timepoint [1] 240566 0
12 months after intervention
Secondary outcome [1] 257168 0
Target lesion revascularization (TLR)is any
ischemia-driven repeat percutaneous
intervention, to improve blood flow, of the
successfully treated target lesion or bypass
surgery of the target vessel with a graft distally to the successfully treated target lesion. A TLR will be considered as ischemia-driven if the target lesion diameter stenosis is 50% by quantitative coronary angiography (QCA) and there is presence of clinical or functional ischemia which cannot be explained by other coronary or graft lesions. Clinical or functional ischemia is any of the following: * The patient has a positive functional study corresponding to the area served by the target lesion
* The patient has ischemic electrocardiogram (ECG) changes at rest in a distribution consistent with the target vessel
* The patient has ischemic symptoms referable to the target lesion A TLR will be considered as ischemia-driven if the lesion diameter stenosis is 70% by QCA even in the absence of clinical or functional ischemia.
Timepoint [1] 257168 0
30 days, 6 months, 12 months, 18 months, 2 years, 3 years, 4 years & 5 years after intervention
Secondary outcome [2] 257169 0
Target vessel revascularization (TVR) is defined as a TLR or a TVR remote. Target lesion revascularization is any ischemia-driven repeat percutaneous intervention, to improve blood flow, of the successfully treated target lesion or bypass surgery of the target vessel with a graft distally to the successfully treated target lesion. A TLR will be considered as ischemia-driven if the target lesion diameter stenosis is 50% by
QCA and there is presence of clinical or
functional ischemia which cannot be explained by other coronary or graft lesions. Clinical or functional ischemia is any of the following:
* The patient has a positive functional study
corresponding to the area served by the target lesion
* The patient has ischemic ECG changes
at rest in a distribution consistent with the target vessel
* The patient has ischemic symptoms referable to the target lesion A TLR will be
considered as ischemia-driven if the lesion
diameter stenosis is 70% by QCA even in the absence of clinical or functional ischemia
* Target vessel revascularization remote is any ischemia driven repeat percutaneous
intervention, to improve blood flow, or bypass surgery of not previously existing lesions diameter stenosis 50% by QCA in the target vessel, excluding the target lesion.
A TVR will be considered ischemia driven if the target vessel diameter stenosis is 50% by QCA and any of the
following are present:
* The patient has a positive functional study corresponding to the area served by the target lesion
* The patient has ischemic ECG changes at rest in a distribution consistent with the target vessel
* The patient has ischemic symptoms referable to the target lesion A TVR will be considered as ischemia-driven if the lesion diameter stenosis is 70% by QCA even in the absence of clinical or functional ischemia.
