Balloon Lithoplasty for Preparation of Severely Calcified Coronary Lesions (BALI)
Balloon Lithoplasty for Preparation of Severely Calcified Coronary Lesions Before Stent Implantation - a Nationwide Randomized Trial (BALI)
Study Overview
Status
Intervention / Treatment
Detailed Description
Severely calcified coronary stenoses are difficult to treat with percutaneous coronary intervention (PCI) using current techniques. Severe calcifications make it difficult to sufficiently prepare lesions before stenting, to advance stents, and to achieve full stent expansion. There is increased risk of vessel dissection and perforation with angioplasty on severely calcified lesions, and long-term outcomes of PCI are adversely affected. Because severely calcified lesions are often excluded from interventional studies, there is little specific evidence on how to best treat these cases. Only a few randomized studies have specifically explored this question, focusing on the use of rotational atherectomy
Recently, the technique of balloon-based lithoplasty was made commercially available. With this technique, calcifications are cracked with the creation of high-frequency pressure oscillations in a special angioplasty balloon. Standard techniques are used to deliver and dilate the balloon. The method was developed for treatment of otherwise non-dilatable lesions, and first reported results have been encouraging. The lithoplasty device used in the current study (Shockwave IVL, Shockwave Medical, CA, USA) has received CE-mark and post-approval safety has recently been confirmed for treatment of severely calcified coronary lesions in patients.
Besides obvious benefits in non-dilatable lesions for which interventional cardiologists have few other options, it is possible this technique could change the way all severely calcified lesions are treated. Balloon lithoplasty could theoretically crack plates of calcium in the vessel wall in an orderly fashion, which could lead to safer and quicker preparation of severely calcified lesions. Furthermore, a better softening of vessel wall calcium could allow full and symmetric expansion of coronary stents, which could lead to better long-term stent patency.

Arms and Interventions

Intervention / Treatment |
---|---|
Active Comparator: Lithoplasty lesion preparation
Balloon lithoplasty will be used as lesion preparation.
|
The lithoplasty balloon should be utilized as early as possible. If it is necessary for passage of the lithoplasty balloon, the lesion may first be predilated with an undersized conventional balloon, non-compliant or semi-compliant. If passage of the lithoplasty balloon is still not possible, it is recommended to perform rotational atherectomy with a small burr size. The lithoplasty balloon is sized 1:1 to reference diameter. Lithoplasty is performed with the balloon dilated at 4 atmospheres, and 10 shocks are delivered, after which the balloon is expanded to 6 atmospheres for 30 seconds, and then deflated. Up to 8 series of balloon expansion/deflation can be delivered in this manner if necessary, and several balloons may be used for long lesions.

Active Comparator: Conventional lesion preparation
Conventional and modified balloons will be used as lesion preparation.
|
Lesion preparation is performed starting with conventional balloons, non-compliant or semi-compliant.
Unless fully satisfactory dilatation is achieved with conventional balloons, it is recommended to also use modified balloons (scoring balloons, cutting balloons).
If balloons cannot be passed or if dilatation is inadequate, the lesion may first be predilated with an undersized conventional, non-compliant, or semi-compliant balloon.
If necessary, rotational atherectomy with a small burr size can be used to facilitate adequate balloon preparation.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of patients with combined outcome of strategy failure
Time Frame: 1 year
|
Failed stent delivery, residual area stenosis ≥ 20% (OCT-assessed) after PCI, or target vessel failure. Residual area stenosis will be defined as [minimal stent area/reference area]. The reference area will be calculated by averaging the proximal and distal reference areas, which will be determined by measuring the lumen contours on most healthy-looking frame of the final OCT in the 0-5 mm edge segments. If a reference cannot be measured on the final OCT, it will be measured on a pre-stent OCT or by using quantitative coronary angiography if pre-stent OCT is unavailable. Target vessel failure will be defined as cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization). |
