Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients undergoing elective coronary percutaneous intervention comparing limus-eluting balloon vs. limus-eluting stents.
Drug Eluting Stents (DES) are the devices of choice for coronary angioplasty, including in patients with high-bleeding risk. Different studies have been done to determine which strategy improves bleeding outcomes without risking the benefit of stenting. Different Double Anti-Platelet Therapy (DAPT) durations in different devices have shown that it is safe to reduce DAPT, with an increase in ischemic events but a better net clinical outcome. Safety and efficacy of Drug Eluting Balloons (DEB) were proved when it was compared with Bare Metal Stents (BMS) in de-novo coronary lesions by presenting no events of target vessel closure after treatment. Our hypothesis is that treating this group of high-bleeding risk patients with DEB will be no-inferior in terms of target vessel failure at 12 months when compared with DES for treatment of de-novo coronary lesions in high bleeding risk population, reducing incidence of significant bleeding events with DAPT reduction.

Size (diameter and length) will be chosen at operator's discretion aid by simple angiography, quantitative coronary analysis (QCA), or intravascular image; so that the lesion previously prepared and 2 mm at each end are covered by DEB, and the diameter and pressure used aims a balloon to artery ratio of 1. In case of significant recoil (more than 30% for main vessels and 50% for side vessels), coronary perforation or flow limiting dissection, provisional stent will be implanted with a stent to artery ratio of 1.1 with stent post-dilatation when indicated. Device will be used in accordance with the CE mark instructions. DAPT will be given for a month with aspirin and a P2Y12 inhibitor (clopidogrel will be favored). Single anti-platelet therapy (SAPT) with aspirin will be continued thereafter.

Target Lesion Failure (TLF)
Composed of cardiovascular death, myocardial infarction related to the treated vessel or ischemia driven target lesion revascularization
Time frame: 12 months
Cardiovascular death
Rate of death resulting from cardiovascular causes in each group: Death caused by acute MI Death caused by sudden cardiac, including unwitnessed, death Death resulting from heart failure Death caused by stroke Death caused by cardiovascular procedures Death resulting from cardiovascular hemorrhage Death resulting from other cardiovascular cause Any MI not clearly attributable to a non-target vessel will be considered as target-vessel MI. Percutaneous coronary intervention (PCI) related MI is termed type 4a MI.
Time frame: 12 months
Myocardial Infarction related to the treated vessel
Rate of myocardial infarction related to the treated vessel (according to the 4th international definition of myocardial infarction) in each group: detection of an increase or decrease in cardiac troponin values with at least 1 of the values above the upper reference limit of the 99th percentile and at least 1 of the following conditions : Symptoms of acute myocardial ischemia. New ischemic changes in the electrocardiogram. Appearance of pathological Q waves. Imaging evidence of loss of viable myocardium or new regional abnormalities in myocardial wall mobility following a pattern compatible with ischemic etiology. Identification of a coronary thrombus by angiography with intracoronary imaging or by autopsy Any MI that cannot be clearly attributed to a vessel other than the revascularized one will be considered as MI related to the treated vessel.
Time frame: 12 months
Target Lesion Revascularization
Rate of repeated percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion
Time frame: 12 months

Target Vessel Failure (TVF)
Rate of TVF in each group (composed of cardiovascular death, myocardial infarction related to the treated vessel or ischemia driven target vessel revascularization)
Time frame: 12 months
Target Vessel Revascularization
Rate of repeated percutaneous intervention or surgical bypass of any segment of the target vessel in each group.

Death caused by infection (includes sepsis) 4. Death resulting from gastrointestinal causes 5. Death resulting from accident/trauma 6. Death caused by other noncardiovascular organ failure 7. Death resulting from other noncardiovascular cause
