About this study
Official title: Super High-pressure Balloon Versus Intravascular Lithotripsy to Prepare Severely Calcified Coronary Lesions: a Randomized Controlled Trial (Shape)
this trial aimed to evaluate the stent expansion through intravascular imaging (optical coherence tomography (OCT) \& intravascular ultrasound (IVUS)) among individuals underwent different preparation techniques ,then comparing the efficacy and safety of super high-pressure balloon to IVL in severely calcified lesions
Read the detailed description
Calcified lesions posed a significant challenge in percutaneous coronary intervention (PCI). The existence of calcified plaque increased the difficulty of optimal stent expansion and the risk of target lesion failure(TLF). Consequently, optimizing the preparation techniques for calcified lesions before stent implantation has assumed growing importance.
As a kind of novel double-layered balloon, super high-pressure balloon can expand uniformly under extreme pressure. Previous studies have demonstrated that super high-pressure balloon perform non-inferiorly or superiorly to other strategies in terms of final stent expansion.
Through triggering localized pulsatile sonic pressure, intravascular lithotripsy(IVL) cracked intimal and medial calcium plaque within the artery. In present series of studies(DISRUPT), the optimized preparation of calcified lesions with IVL has been proved to be safe and effective. According to guidelines and clinical practice, IVL is applicable to different types of severe calcification lesions, including concentric and eccentric calcifications. However, considering its technological and economic costs, finding other preparation techniques non-inferiority to IVL was essential. In clinical practice, super high-pressure balloon had shown considerable effects of preparation for calcified lesions. However, study focused on the comparison of super high-pressure balloon with IVL for severe calcified lesions was limited.
In summary, this randomized trial aimed to evaluate the stent expansion through intravascular imaging among individuals underwent different preparation techniques ,then comparing the efficacy and safety of super high-pressure balloon to IVL in severely calcified lesions

What is being measured
The primary outcome is the main question the study is designed to answer.
stent expansion index
The stent expansion was associated with post-PCI clinical outcomes and the risk of stent failure.In this study, the primary endpoint was stent expansion index, which was defined as the final minimal luminal area (MLA) within the treated segment divided by the average reference vessel area assessed with intravascular imaging (optical coherence tomography(OCT)\&intravascular ultrasound(IVUS)).
Measured: Intraprocedural
Secondary outcomes (1)
30-days major adverse cardiac event (MACE)
The secondary endpoint was defined as the occurrence of major adverse cardiac events within 30 days, which was defined as a composite of cardiac death, target vessel-related myocardial infarction [TVMI] and clinically driven target vessel revascularisation[TVR].
Measured: 30 days
