Evaluation of safety and efficacy of coronary intravascular lithotripsy for treatment of severely calcified coronary stenoses: Design and rationale for the Disrupt CAD III trial.

Coronary calcification limits optimal stent expansion and apposition and worsens safety and effectiveness outcomes of percutaneous coronary intervention (PCI). Current ablative technologies that modify calcium to optimize stent deployment are limited by guidewire bias and periprocedural complications related to atheroembolization, coronary dissection, and perforation. Intravascular lithotripsy (IVL) delivers pulsatile ultrasonic pressure waves through a fluid-filled balloon into the vessel wall to modify calcium and enhance vessel compliance, reduce fibroelastic recoil, and decrease the need for high-pressure balloon (barotrauma) inflations.

The OPTIMIZE randomized trial to assess safety and efficacy of the Svelte IDS and RX Sirolimus-eluting coronary stent Systems for the Treatment of atherosclerotic lesions: Trial design and rationale.

Coronary stenting without angioplasty pretreatment (direct stenting) may simplify procedures in appropriate lesions. Direct stenting is facilitated by smaller profile coronary stent platforms. The present study was designed for regulatory approval of a novel drug-eluting coronary stent and incorporates both randomized comparison for non-inferiority to an approved predicate device as well as a nested evaluation of subjects eligible for direct stenting.

Rationale and design of the EVOLVE Short DAPT Study to assess 3-month dual antiplatelet therapy in subjects at high risk for bleeding undergoing percutaneous coronary intervention.

Background: While extended dual antiplatelet therapy (DAPT) with aspirin and a platelet (P2Y) inhibitor after percutaneous coronary intervention (PCI) reduces the risk of stent thrombosis (ST) and myocardial infarction (MI), it also increases bleeding. Newer generation drug-eluting stents with bioabsorbable polymer coatings may reduce thrombotic events and allow abbreviated DAPT in selected patients. The EVOLVE Short DAPT study is designed to evaluate the safety of 3-month DAPT in high bleeding risk subjects treated with the SYNERGY bioabsorbable polymer everolimus-eluting stent.

Efficacy and safety of alirocumab in patients with or without prior coronary revascularization: Pooled analysis of eight ODYSSEY phase 3 trials.

Background And Aims: Patients with atherosclerotic cardiovascular disease (ASCVD) and prior revascularization are at high risk of further cardiovascular events and may require additional lipid-lowering therapies beyond maximally tolerated statin therapy. We assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in patients with ASCVD, with or without prior coronary revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG]).

Methods: Data from eight controlled (placebo/ezetimibe) phase 3 ODYSSEY trials were pooled and stratified by trial design: alirocumab 150 mg or 75 mg with possible dose increase to 150 mg (75/150 mg) every 2 weeks (Q2W) versus placebo, and alirocumab 75/150 mg Q2W versus ezetimibe.

3-Year Clinical Outcomes With Everolimus-Eluting Bioresorbable Coronary Scaffolds: The ABSORB III Trial.

Background: The Absorb everolimus-eluting poly-L-lactic acid-based bioresorbable vascular scaffold (BVS) provides early drug delivery and mechanical support functions similar to metallic drug-eluting stents (DES), followed by complete bioresorption in approximately 3 years with recovery of vascular structure and function. The ABSORB III trial demonstrated noninferior rates of target lesion failure (cardiac death, target vessel myocardial infarction [TVMI], or ischemia-driven target lesion revascularization) at 1 year in 2,008 patients with coronary artery disease randomized to BVS versus cobalt-chromium everolimus-eluting stents (EES).

Objectives: This study sought to assess clinical outcomes through 3 years following BVS implantation.

Efficacy and Safety of the Absorb Bioresorbable Vascular Scaffold in Females and Males: Results of an Individual Patient-Level Pooled Meta-Analysis of Randomized Controlled Trials.

Objectives: Because females are under-represented in coronary trials, this study sought to assess the relative safety and efficacy of Absorb bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) and the Xience everolimus-eluting stent in females compared with males.

Background: The Absorb everolimus-eluting BVS provides drug delivery and mechanical support similar to a metallic drug-eluting stent, followed by resorption and restoration of more normal vascular structure with the potential to improve late clinical outcomes.

Methods: The ABSORB II, ABSORB III, ABSORB Japan, and ABSORB China trials were pooled.

Efficacy and Safety of the Absorb Everolimus-Eluting Bioresorbable Scaffold for Treatment of Patients With Diabetes Mellitus: Results of the Absorb Diabetic Substudy.

Objectives: The study sought to evaluate the efficacy and safety of the Absorb everolimus-eluting bioresorbable vascular scaffold (BVS) (Abbott Vascular, Abbott Park, Illinois) in patients with diabetes mellitus.

Background: Randomized, controlled trials have demonstrated comparable clinical outcomes following percutaneous coronary intervention with either Absorb BVS or metallic Xience everolimus-eluting stent. However, these trials lack power required to provide reliable treatment effect estimates in this high-risk population.

Efficacy and safety of the proprotein convertase subtilisin/kexin type 9 inhibitor alirocumab among high cardiovascular risk patients on maximally tolerated statin therapy: The ODYSSEY COMBO I study.

Background: The ODYSSEY COMBO I study (http://clinicaltrials.gov/show/NCT01644175) evaluated efficacy and safety of alirocumab as add-on therapy to stable maximally tolerated daily statin with or without other lipid-lowering therapy in high cardiovascular risk patients with suboptimally controlled hypercholesterolemia.

Methods: This multicenter, phase 3, randomized (2:1 alirocumab vs placebo), double-blind, 52-week trial enrolled 316 patients with established coronary heart disease or coronary heart disease risk equivalents and hypercholesterolemia.
