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. Methods retrospective analysis included all patients who underwent PCI with at single center between January 2013 October 2024. Data were collected from prospective registry....
Tip detection-antegrade dissection and re-entry (TD-ADR) technique allows operators to accurately observe both guidewire tip direction a true lumen in chronic total occlusion (CTO) lesions, while the torque of on IVUS images does not invariably correspond that fluoroscopic images.
This study aimed to evaluate the outcomes of patients with in-stent restenosis (ISR) who underwent rotablation (RA) followed by balloon angioplasty (BA), drug-eluting stent (DES) implantation, or drug-coated (DCB) angioplasty.Interventional treatment ISR is occasionally challenging. Despite availability various percutaneous treatments, optimal solution remains unclear.A total 200 RA were retrospectively identified from our institutional database. Clinical at 12 months and independent...
Abstract Objectives The aim of this study was to evaluate the clinical outcomes rotational atherectomy (RA) followed by new‐generation drug‐eluting stent (DES) implantation in patients with an extensive amount calcified and fibrotic plaque. Background RA DES for complex lesions has not been thoroughly evaluated. Methods A total 744 consecutive (770 lesions) treated following de novo between January 2013 November 2015 were retrospectively identified using our institutional database. Clinical...
Abstract Background The ideal method for recanalization of complex peripheral lesions has not been determined, despite the use latest endovascular devices. We describe a novel fully percutaneous anatomical bypass, named “needle bypass” technique, treatment vascular with failed previous surgical therapy. Main text A 68-year-old male patient chronic limb-threatening ischemia presented to our department. He previously had received 10 years prior that included removal right distal common femoral...
Abstract Objectives To examine the safety, efficacy, and efficiency of PlasmaWire TM System to recanalize coronary chronic total occlusions (CTO) using controlled ablation inside CTO. Background The is a new bipolar radiofrequency (RF) wire system utilizing plasma‐mediated facilitate crossing in CTOs. Two independent wires are used tandem for channel creation by applying RF energy between tips so as localize ablation. Methods Prospective, nonrandomized, single‐arm, multicenter study seven...
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...
To introduce a modified rotational atherectomy (RA) procedure and investigate the early midterm outcomes of RA-facilitating diversified percutaneous coronary intervention (PCI) in large group aged patients with higher cardiovascular risk.Previous studies about RA were limited small sample size low-risk population.Between January 2013 November 2015, 1169 consecutive treated RA-facilitated PCI retrospectively enrolled, including de novo calcified lesions in-stent restenosis. Patients regularly...
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...
Objective To investigate the effects of antithrombotic therapy on target lesion revascularisation (TLR) and major adverse cardiovascular cerebrovascular events (MACCEs) at 12 months after femoropopliteal intervention with second-generation bare metal nitinol stents. Methods A total 277 lesions in 258 limbs 248 patients de novo atherosclerosis above-the-knee segment were analysed from Japan multicentre postmarketing surveillance. Results At discharge, dual antiplatelet (DAPT) was prescribed...
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. The present study aims explore whether POBA comparably DES large coronary pretreated by ROTA clinical outcomes.Consecutive patients treated for lesions (≥ 3 mm) using + or were retrospectively analyzed. major adverse cardiac events (MACE),...
Objective. Coil embolization (CE) for coronary artery perforation (CAP) has not been thoroughly evaluated. This study aimed to evaluate the extent of myocardial damage and impact on cardiac function after CE CAP. Methods. A total 110 consecutive patients treated with CAP were retrospectively identified. The degree Results. Forty-nine (44.5%) cases involved chronic occlusions. guidewire was cause in 97 (88.2%) patients. success rate 98.2%. Almost all prescribed either antiplatelet drugs or...
Abstract A coronary hematoma, which can sometimes obstruct flow, may be left behind after tip‐detection antegrade dissection and reentry. We present a novel bailout technique utilizing subintimal trans‐catheter withdrawal with the assistance of stent balloon. This used before performing long stenting or fenestration procedure cutting balloon, are standard treatments for to improve impaired flow caused by distally extended hematoma.
Background: Drug-coated balloons (DCB) have emerged as an effective treatment for in-stent restenosis and small vessel disease. DCB angioplasty might improve outcomes in heavily calcified lesions, a challenge the current era of drug-eluting stents (DES). Calcified nodules (CN) also remain problematic due to high incidences target lesion revascularization (TLR). However, there is limited evidence comparing efficacy DES lesions requiring rotational atherectomy (RA), including those with CN....
Limited evidence exists regarding the long-term outcomes of true vs. non-true coronary bifurcation lesions (CBLs) treated with current-generation drug-eluting stents and intravascular imaging guidance. The SCVC (Sapporo Cardiovascular Clinic) registry was a prospective, single-center, all-comers enrolling 1,727 consecutive patients bioresorbable polymer sirolimus-eluting stent (BP-SES) under complete From this registry, 440 CBLs (25.5%) were analyzed. Patients categorized into CBL groups...
Burr entrapment is a potentially life-threatening complication of rotational atherectomy (RA). However, owing to its infrequency, there have been no major reports on burr entrapment. This study aimed evaluate the incidence, treatment, and outcomes entrapment.This multicenter retrospective analyzed patients who had undergone percutaneous coronary interventions (PCIs) were treated by RA between May 2013 March 2022.Of 22 640 PCI procedures, was performed in 3195 (14.1%), among whom occurred...
Percutaneous coronary intervention (PCI) in hemodialysis patients with severely calcified and diffused lesions is associated extremely high rates of major adverse cardiovascular events (MACE), even when facilitated by rotational atherectomy (ROTA). Potential risk factors for MACE ROTA-facilitated PCI should be identified.We retrospectively analyzed a consecutive cohort from the Sapporo Cardiovascular Clinic database, who were on maintenance severe treated PCI.
