RECRUITINGTarget lesion revascularization
Defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. All TLRs should be classified prospectively as clinically indicated or not clinically indicated by the investigator prior to repeat angiography. Clinically indicated revascularization: A revascularization is considered clinically indicated if angiography at followup shows a percent diameter stenosis ≥ 50% and if one of the following occurs: 1. A positive history of recurrent angina pectoris, presumably related to the target vessel; 2. Objective signs of ischemia at rest (ECG changes) or during exercise test (or equivalent), presumably related to the target vessel; 3. Abnormal results of any invasive functional diagnostic test (eg, Doppler flow velocity reserve, fractional flow reserve); 4. A TLR or TVR with a diameter stenosis ≥ 70% even in the absence of the above-mentioned ischemic signs or symptoms.
Time frame: Up to 20 years

Non-target vessel revascularization
Any revascularization of target-vessel revascularization will be collected.
Time frame: Up to 20 years
Cerebrovascular accident
Sudden onset of vertigo, numbness, aphasia, dysarthria or central neurologic deficit secondary to vascular lesions of the brain such as hemorrhage, embolism, thrombosis, or rupturing aneurysm, that persist for \> 72 hours.
Time frame: Up to 20 years
Major bleeding
Any bleeding event will be collected with following description; the amount of hemoglobin drop or transfusion, the site of bleeding, any further treatment for the bleeding.
Time frame: Up to 20 years
