Treatment of heavily calcified coronary artery stenosis using 3.5 mm peripheral intravascular lithotripsy balloon: case series.

ABSTRACT:

Background

Prevalence of coronary artery calcification is high among patients with advanced age, chronic kidney disease, and diabetes. Percutaneous coronary intervention of heavily calcified coronary artery remains a significant challenge for interventional cardiologists. Although there are several modalities available in treating calcified coronary arteries, lesion preparation of certain heavily calcified vessels remains inadequate prior to stent deployment and/or often associated with worse periprocedural adverse outcomes.

Case summary

We report feasibility and safety of 3.5?mm peripheral intravascular lithotripsy (IVL) for the treatment of severely calcified coronary stenosis in two patients after orbital atherectomy failed to debulk calcified plaque to enable stent deployment.

Discussion

Intravascular lithotripsy has recently emerged as a therapeutic option in treating calcified peripheral artery disease. However, coronary IVL is currently available only in a few centres in the USA. Studies are ongoing in the safety and efficacy of this technology in treating coronaries.

Project description:IntroductionThe combination of intravascular lithotripsy (IVL) and drug-coated balloon (DCB) angioplasty for calcified peripheral lesions is associated with promising short-term results. However, data regarding the 12 months performance of this treatment option is missing. This study reports on the outcomes of IVL and DCB angioplasty for calcified femoropopliteal disease.MethodsPatients treated with IVL and DCB for calcified femoropopliteal lesions between February 2017 and September 2020 were included into this study. The primary outcome measure of this analysis was primary patency. Secondary patency, freedom from target lesion revascularization (TLR) and overall mortality were additionally analyzed.ResultsFifty-five (n = 55) patients and 71 lesions were analyzed. Most patients presented with long-term limb-threatening ischemia (n = 31, 56%), 47% (n = 26) were diabetics, and 66% (n = 36) had long-term kidney disease. The median lesion length was 77 mm (interquartile range: 45-136), and 20% (n = 14) of the lesions were chronic total occlusions (CTOs). Eccentric calcification was found in 23% of the vessels (n = 16), and circumferential calcium (peripheral arterial calcium scoring system [PACSS] Class 3 and 4) was present in 78% (n = 55) of the treated lesions.The technical success after IVL amounted to 87% (n = 62) and the procedural success to 97% (n = 69). A flow-limiting dissection was observed in 2 cases (3%). Both the rates of target lesion perforation and distal embolization were 1% (n = 1). A bail-out scaffold was deployed in 5 lesions (7%). At 12 months the Kaplan-Meier estimate of primary patency was 81%, the freedom from TLR was 92% and the secondary patency 98%. The overall survival amounted to 89%, while the freedom from major amputation to 98%. The presence of eccentric disease, CTOs, or PACSS Class 4 did not increase the risk for loss of patency or TLR.ConclusionsIn this challenging cohort of patients, the use of IVL and DCB for calcified femoropopliteal lesions was associated with promising 12 months outcomes and an excellent safety profile.
