Outcomes

Primary Outcome Measures

In-stent Late Lumen Loss
In-stent is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon. Late lumen loss is defined as the difference between minimal luminal diameter after procedure and at 6 months, as evaluated by offline quantitative coronary angiography (QCA). Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).

Secondary Outcome Measures

In-segment Late Lumen Loss
In-segment is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon plus 5 mm proximal and 5 mm distal. Late lumen loss is defined as the difference between minimal luminal diameter after procedure and at 6 months, as evaluated by offline quantitative coronary angiography (QCA). Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
Cumulative Major Adverse Cardiac Events Rate (Composite of Cardiac Death, Non-fatal Myocardial Infarction, Clinically Driven Target Lesion Revascularization, Clinically Driven Target Vessel Revascularization)
All safety endpoint and serious adverse events were adjudicated by an independent clinical events committee. Major Adverse Cardiac Events = MACE Myocardial Infarction = MI Target Lesion Revascularization = TLR Target Vessel Revascularization = TVR
Cumulative MACE Rate (Composite of Cardiac Death, Non-fatal MI, Clinically Driven TLR, Clinically Driven TVR)
All safety endpoint and serious adverse events were adjudicated by an independent clinical events committee.
In-stent Diameter Stenosis (%DS)
In-stent is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon. Diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
In-segment Diameter Stenosis (%DS)
In-segment is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon plus 5 mm proximal and 5 mm distal. Diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
Binary In-stent Restenosis
In-sent is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon. Binary restenosis was defined as a ≥ 50% diameter stenosis at follow-up as evaluated by offline quantitative coronary angiography (QCA). Diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
Binary In-segment Restenosis
In-segment is defined as from proximal shoulder to distal shoulder of the dilated Pantera Lux balloon plus 5 mm proximal and 5 mm distal. Binary restenosis was defined as a ≥ 50% diameter stenosis at follow-up as evaluated by offline quantitative coronary angiography (QCA). Diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
Technical Success
Technical success is defined as successful vascular access, completion of the endovascular procedure and immediate morphological success with < 30% residual diameter stenosis assessed by quantitative coronary angiography (QCA). Diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
Device Success
Device success defined as exact deployment of the device as documented by two different projections assessed by quantitative coronary angiography (QCA). Offline quantitative coronary angiography (QCA) analysis was performed by an independent core laboratory (Ulrich Dietz, MD, Deutsche Klinik für Diagnostik, Wiesbaden, Germany).
