Background: Rotational atherectomy (RA) is relatively contraindicated in patients with lesions ≥25 mm of length. Aim of this study was to evaluate RA safety and efficacy in this subset of patients with new technology and devices.
Objectives: To report procedural and 30-day outcomes following percutaneous transcatheter valve-in-valve (VIV) implantation for tricuspid bioprosthesis failure, with a new generation balloon-expandable transcatheter aortic valve implantation prosthesis.
Objectives: We sought to demonstrate the safety and efficacy of rapid left ventricular (LV) pacing through the guidewire during balloon aortic valvuloplasty (BAV) and Transaortic valve implantation (TAVI).
Objectives: To evaluate the feasibility and safety of direct transcatheter aortic valve implantation (TAVI) by the transfemoral approach without balloon pre-dilatation using the Edwards SapienXT valve.
Objective: The objective of this study was to evaluate safety, efficacy, and durability of coil embolization of the major septal perforator of the left anterior descending coronary artery in patients with hypertrophic obstructive cardiomyopathy (HOCM).
Background: The efficacy of transcatheter aortic valve replacement (TAVR) in aortic stenosis patients at high surgical risk has been established. The data on patients with intermediate risk is not conclusive. We performed a meta-analysis of studies which compared TAVR with surgical aortic valve replacement (SAVR) in patients at intermediate surgical risk.
Background: Metallic endovascular stents are utilized off-label in congenital heart disease. Biodegradable stents (BDS) offer potential advantages in a growing child. We have previously reported double opposed helical (DH) BDS up to 6 mm diameter (DH-6). The objectives are to investigate the bench characteristics of larger 8 mm diameter BDS (DH-8) manufactured with increasing strut thicknesses and the inflammatory profile in a porcine model.
Objectives: The purpose of this study was to evaluate clinical outcomes after percutaneous coronary intervention (PCI) in patients with coronary artery calcification (CAC).
Objectives: We aimed to investigate procedural feasibility and outcomes associated with planned rotational atherectomy (RA) for severely calcified coronary lesions. Background: Limited data are available addressing the benefits of planned RA compared to provisional RA.
Objective: To determine the rate of bioresorbable vascular scaffold (BVS) thrombosis in a large, real-world population.
Objectives: The objective of this study was to investigate clinical outcomes following single crossover bioresorbable scaffold (BRS) implantation without routine side branch (SB) strut dilation.
Objectives: To investigate outcomes following bifurcation double-stenting utilizing a bioresorbable scaffold (BRS) in the main branch (MB) and either a BRS or metallic drug-eluting stent (DES) in the side branch (SB).
Objective: There is an ongoing controversy regarding the efficacy and safety of different percutaneous stenting techniques for coronary bifurcation lesions needing >1 stent. The promise of safe vessel restoration with bioresorbable scaffolds (BRS) may not be transferable to complex double BRS bifurcation techniques, and permanent metallic scaffolding of the bifurcation core may be needed. We identified modified-T stenting as the most promising fully bioresorbable 2-stent strategy in a preclinical setting. The objective of this study is to assess acute performance and compare long-term vessel healing with this strategy, versus an approach combining BRS with a dedicated metallic drug-eluting bifurcation stent.
Background: The aim of this study was to assess whether deferred stenting (DS) reduces infarct size and microvascular obstruction (MVO) compared with immediate stenting (IS) in primary percutaneous coronary intervention for ST-segment–elevation myocardial infarction.
Background: Clinical consequences of optical coherence tomographic (OCT) high-definition visualization of plaque/stent structures in acute patients remain undefined. In this retrospective substudy, we assessed the prognostic impact of postprocedural culprit lesion OCT findings in patients with acute coronary syndrome undergoing percutaneous coronary intervention.
