Intravascular Lithotripsy for Calcified Left Main Artery Disease.

ABSTRACT: Left main coronary artery disease subtends a large area of potentially jeopardized myocardium. Percutaneous coronary intervention for severe left main coronary artery disease is a reasonable treatment option for select patients. Severe coronary artery calcium of the left main artery increases the complexity of percutaneous coronary intervention and is associated with increased risk of periprocedural complications and worse long-term clinical outcomes. Intravascular lithotripsy (IVL) utilizes sonic pressure waves to modify severe coronary artery calcium and has emerged as a safe and effective alternative to coronary atherectomy. However, left main lesions were excluded from regulatory approval clinical trials of IVL. Herein, we review all available data regarding the use of IVL treatment for severe left main coronary artery disease.

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.
