Coronary Artery Disease
Conditions
Brief summary
Stent under-expansion during percutaneous coronary intervention (PCI) is one of the suboptimal results associated with a higher risk of restenosis and thrombosis. In order to obtain an optimal stent expansion, especially in lesions with calcific or fibrotic plaque, the appropriate lesion preparation before stent implantation is a crucial phase. For this, different devices are used in everyday practices, including non-compliant balloon (NC), scoring / cutting balloons or rotational atherectomy; however, their effectiveness depends on the experience and skill of the operator. The purpose of this study is to assess the feasibility, efficacy and safety of a novel scoring balloon intended to treat calcific or fibrotic plaque of a coronary lesion

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Stent expansion in calcified lesions assessed by stent diameter calculation using quantitative and intravascular analysis after lesion preparation using a scoring balloon is superior to conventional lesion preparation | Intravascular ultrasound (IVUS) or quantitative analysis is directly done after procedure | The measure of stent expansion in calcified coronary lesions as assessed by quantitative coronary angiography, enhanced stent imaging and intravascular ultrasound after lesion preparation using the novel scoring semi-compliant and noncompliant balloons are superior (p\<0.05) to semi compliant and non-compliant balloons. |
Secondary
| Measure | Time frame |
|---|---|
| Rate of successful predilatation of calcified lesions of a scoring semi-compliant/non-compliant balloon and semi-compliant (SC)/ non-compliant (NC) balloon | Directly after procedure |
| Rate of residual under-expansion of stent after post-dilatation with a non-compliant balloon | Directly after procedure |
| Rate of procedural complication (composite of cardiac death, myocardial infarction, coronary artery perforation and cardiac tamponade) of a scoring balloon and a SC/NC balloon followed by stenting. | 1 month follow up |
