Purpose: The purpose of the study is to report 12-month efficacy and safety results from the subgroup of Japanese patients in the prospective IMPERIAL 2:1 randomized controlled trial (RCT).
Methods: The global IMPERIAL RCT was designed to compare performance of the Eluvia Drug-Eluting Vascular Stent System (Boston Scientific, Marlborough, MA, USA) with the Zilver PTX Drug-Eluting Peripheral Stent (Cook Medical, Bloomington, IN, USA) for treatment of femoropopliteal artery lesions. Patients with symptomatic (Rutherford category 2-4) disease were included.

Purpose: To determine the clinical impact and predictors of slow flow after endovascular treatment (EVT) using the Crosser catheter for debulking infrapopliteal lesions associated with critical limb ischemia.
Materials And Methods: This retrospective study included 65 patients with critical limb ischemia (70 limbs, 90 infrapopliteal lesions), who underwent EVT using the Crosser catheter between November 2011 and February 2017. The Crosser catheter was used when the balloon catheter could not be passed through the lesion or could not be dilated sufficiently.
This study is aimed to evaluate the performance of MAGGIC risk score for predicting mortality by external validation using multicenter transcatheter aortic valve replacement (TAVR) registry. We assessed 1383 patients who underwent TAVR from October 2013 to April 2016. Patients were divided into 2 groups according to the median of MAGGIC score and we compared the incidence of all-cause death between high and low MAGGIC score.

We aimed to compare the angiographic outcomes between repeat drug-eluting stent (DES) implantation and drug-coated balloon (DCB) treatment for restenotic lesion caused by stent fracture (SF). The treatment of restenotic lesion caused by SF after DES implantation has not been well evaluated. From April 2007 to April 2015, 9320 lesions were implanted with a DES during percutaneous coronary intervention in our hospital; of those, 815 lesions (8.

Objectives: The aim of this study was to compare 7-year outcomes between the first-generation sirolimus-eluting stent (SES) and the new-generation everolimus-eluting stent (EES) in a randomized clinical trial.
Background: There is a scarcity of very long-term (beyond 5 years) data from clinical trials investigating whether new-generation drug-eluting stents have clear clinical advantages over first-generation drug-eluting stents.
Methods: RESET (Randomized Evaluation of Sirolimus-Eluting Versus Everolimus-Eluting Stent Trial) is the largest randomized trial comparing EES with SES (NCT01035450).

Aim: We sought to investigate the efficacy of the proximal optimization technique (POT) on crossover stenting followed by side branch (SB) dilation under optical coherence tomography guidance in a multicenter registry study.
Methods And Results: A total of 135 bifurcation lesions in 134 patients were divided into POT (n = 52) and non-POT groups (n = 83). The POT was performed before SB dilatation (pre-POT; n = 26), finally (final-POT; n = 12), at both timing (re-POT; n = 13), and uncertain (n = 1).

The appropriate stent platform for treating coronary bifurcation lesions (CBLs) remains controversial. Previous bench tests have demonstrated the superiority of a 2-link cell design to 3-link cell design for creating inter-strut dilation at the side branch ostium. This randomized multicenter prospective BEGIN trial compared the biodegradable polymer-based biolimus A9-eluting stent (2-link BES) with the durable polymer-based cobalt chromium everolimus-eluting stent (3-link EES) in 226 patients with de novo CBLs.

Background: The occurrence and clinical impact of untreated subclinical leaflet thrombosis beyond 1 year after transcatheter aortic valve replacement still remain unclear.
Methods And Results: In a multicenter transcatheter aortic valve replacement registry, we analyzed data from 485 patients who underwent 4-dimensional multidetector computed tomography posttranscatheter aortic valve replacement performed to survey hypoattenuated leaflet thickening with reduced leaflet motion compatible with thrombus at a median of 3 days, 6 months, 1 year, 2 years, and 3 years. Incidence, predictors, and clinical outcomes of early (median 3 days) and late (>30 days) leaflet thrombosis were assessed.

Objectives: The aim of this study was to evaluate the impact of the J-CTO score on long-term target lesion revascularization (TLR) after successful native chronic total occlusion (CTO)-percutaneous coronary intervention (PCI).
Background: We previously reported that the J-CTO score could be used to stratify the lesion complexity and procedural success rate in CTO lesions.
Methods: We evaluated the prognostic significance of a high J-CTO score for long-term TLR rate in the J-CTO Registry.

Little is known about the superiority of balloon angioplasty vs. stent implantation for femoropopliteal (FP) lesions according to subgroup. This study involved 1,018 de novo (balloon angioplasty, n=462; stent implantation, n=556) and 114 in-stent restenosis (ISR) FP lesions (balloon angioplasty, n=69; stent implantation, n=45) treated with endovascular therapy.

Purpose: To report the midterm outcomes of a trial comparing self-expanding nitinol stents to percutaneous transluminal angioplasty (PTA) with provisional stenting in the treatment of obstructive disease in the superficial femoral and popliteal arteries.
Materials And Methods: The SM-01 study ( ClinicalTrials.gov identifier NCT01183117), a single-blinded, multicenter, randomized controlled trial in Japan, enrolled 105 consecutive patients with de novo or postangioplasty restenotic femoropopliteal lesions; after removing protocol violations (1 from each group), 51 patients (mean age 74±8 years; 36 men) in the stent group and 52 patients (mean age 73±8 years; 35 men) in the PTA group were included in the intention-to-treat analysis.
Pre-procedural valvuloarterial impedance (Zva) is considered as a useful predictor of mortality in patients diagnosed as having severe aortic stenosis (AS) who undergo transcatheter aortic valve implantation (TAVI). However, the prognostic significance of post-procedural Zva remains unclear. We aimed to evaluate the prognostic significance of Zva after TAVI.

Background: Underfilled transcatheter aortic-valve implantation with ad hoc post-dilation is a therapeutic option for patients with borderline annuli to avoid acute complication. The effects of this technique on valve leaflet behavior, hydrodynamic performances, and paravalvular leakage (PVL) using patient-specific three-dimensional (3D) aortic-valve models were investigated.
Methods and results: A female octogenarian patient was treated with this technique by using a 23-mm Sapien-XT.

Critical limb ischemia with infected wounds is known to have a poor prognosis and evaluation of infection severity using the Wound, Ischemia, and foot Infection classification system has been recommended. However, little is known about how infection severity influences the clinical outcomes of critical limb ischemia in patients with tissue loss. We investigated the impact of infection severity on the clinical outcomes in critical limb ischemia with tissue loss after endovascular treatment.
