The delivery of the rotational atherectomy burr can sometimes be hindered in distal calcified lesions complicated by proximal vessel tortuosity or other obstacles. This problem may result procedural failure fatal complications, including coronary perforation, entrapment, driveshaft fracture. To prevent these catastrophic outcomes and ensure successful delivery, we introduce DELIVER (Deep Engagement guide catheter 5-F chiLd-guIde for deliVEry subsequent Rotational atherectomy) technique....
ABSTRACT Background Burr fracture during rotational atherectomy (RA) is a rare but potentially devastating complication. Due to its infrequency, comprehensive data on incidence, mechanisms, and management are lacking. This study aimed investigate the contributing factors, strategies for burr fractures RA procedures.

ABSTRACT Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions with ambiguous proximal cap remains challenging. We present a successful CTO‐PCI case involving ambiguity, treated by combining balloon‐assisted subintimal entry (BASE) and tip‐detection antegrade dissection re‐entry (TD‐ADR) techniques. The BASE‐facilitated TD‐ADR technique is novel approach has the potential to enhance safety efficacy of procedures.
Abstract Prognostic impact of anemia complicating severe aortic stenosis (AS) remains unclear. We assessed the on cardiovascular and bleeding outcomes in 3403 patients enrolled CURRENT AS registry. 835 (25%) had mild (hemoglobin 11.0–12.9 g/dl for men/11.0–11.9 women) 1282 (38%) moderate/severe (Hb ≤ 10.9 g/dl) at diagnosis AS. Mild were associated with significantly increased risks relative to no ≥13.0 men/≥12.0 primary outcome measure (aortic valve-related death or heart failure...

Abstract Background Although bioresorbable polymer sirolimus‐eluting Ultimaster stents (BP‐SESs) are likely useful for percutaneous coronary interventions (PCIs), the clinical data from real‐world cases insufficient. Furthermore, predictors of adverse outcomes after BP‐SES implantation have not been fully investigated. Objectives This study evaluated 1‐year in PCI and identified outcomes. Methods In this single‐center, all‐comers study, we consecutively implanted BP‐SESs all patients who...

The patency achieved by conventional peripheral interventions for atherosclerotic lesions in the common femoral artery (CFA), called "no stenting zone", is not superior to that surgical endarterectomy due calcified plaque occupying area. Plaque modification strategies obtain acute gain CFA provide better clinical outcomes than standard balloon angioplasty. Atherectomy devices, which focus on of superficial calcifications, contribute improvement outcomes. However, deep calcifications resist...
Drug-eluting stent (DES) is well known to be effective in severely calcified lesion after rotational atherectomy (ROTA). However, there are still some situations when stents should avoided and plain old balloon angioplasty (POBA) the preferred option.
