This study evaluated whether radial access intervention had a lower risk of post-treatment adverse events in acute coronary syndrome (ACS) even in Japan where the use of a strong antithrombotic regimen was not approved. We retrospectively analyzed a large nation-wide registry in Japan to compare the incidence of post-treatment adverse events according to the types of vessel access (trans-radial; TRI vs. trans-femoral; TFI) among ACS cases (n = 76,835; 43,288 TRI group and 33,547 TFI group). Primary outcome was a composite of in-hospital death, myocardial infarction associated with percutaneous coronary intervention, bleeding complication requiring transfusion, and stent thrombosis during in-hospital stay...

This study aimed to investigate the efficacy of percutaneous transcatheter aortic valvuloplasty (PTAV) performed prior to non-cardiac surgery and the safety of non-cardiac surgery after PTAV in elderly Japanese patients. Between March 2012 and August 2018, 14 patients who underwent PTAVs prior to non-cardiac surgery were enrolled. The mean age was 82.2 ± 7.0 years. A total of 9 patients (64.3%) were women. A retrograde approach was selected for 57.1% of the patients. More than 75% of the procedures were performed using echocardiographic imaging...

Although the antegrade dissection and re-entry technique (ADR) with Stingray system is one of the procedures for percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), it has some risk of side-branch occlusion. This article reports a CTO case in the left circumflex artery successfully treated with combination use of ADR subintimal tracking and intravascular ultrasound (IVUS)-guided re-wiring without side-branch occlusion. Antegrade approach with single-wire and parallel-wire technique was failed...

Balloon occlusion is a potential method for inducing hyperemia to measure post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR). The objective of this study was to determine the clinical usefulness of post-occlusional hyperemia. FFRs measured using post-occlusional hyperemia caused by 30 (FFRoccl30 ) and 60 s (FFRoccl60 ) of balloon occlusion after PCI were compared in 60 lesions from 60 patients. The duration of hyperemia was also measured. There was a strong correlation between FFRoccl30 and FFRoccl60 (r = 0...

Cutting balloons (CBs) and other scoring balloons are known to be useful for plaque modification in heavily calcified lesions. There have been some reports of the efficacy of these balloons compared to conventional balloons. However, there have been no reports exploring which balloon is most effective among these three types of balloons. We, therefore, compared these three balloons with respect to effectiveness in plaque modification of calcified lesions. We retrospectively investigated 201 cases using these three balloons from April 2015 to December 2017...

The aims of this study are to evaluate the efficacy of percutaneous coronary intervention (PCI) using full-metal jacket (FMJ) with second-generation drug-eluting stents (DES). A single-center, non-randomized, retrospective study was performed from May 2005 to February 2014 at Miyazaki Medical Association Hospital, Japan. PCI using FMJ with DES was performed to treat 240 very long lesions (> 60 mm) in 240 patients. Subjects were divided into a first-generation or second-generation DES group. The primary endpoint was the incidence of major adverse cardiac events (MACE) at 2 years...

Severe aortic stenosis (AS) is considered as an independent risk factor for perioperative cardiac complications of non-cardiac surgery. Surgical aortic valve replacement should be considered before non-cardiac surgery in patients with symptomatic severe AS. However, recently, transcatheter aortic valve replacement (TAVR) has emerged as an alternative approach for selected AS patients. We sought to determine the safety and efficacy of TAVR in preparation for major non-cardiac surgery. From our retrospective database, seven patients who underwent TAVR in preparation for major non-cardiac surgery were identified, and their clinical and hemodynamic data were collected...

Preprocedural computed tomography (CT) imaging appears to provide an advantage in localization of the appropriate septal branch targeted for alcohol septal ablation (ASA). The objective of this study was to compare the clinical backgrounds, procedural characteristics, and outcomes of patients who underwent ASA with preprocedural CT assessment against those without CT assessment. Thirty consecutive patients with obstructive hypertrophic cardiomyopathy who underwent ASA were retrospectively included. Patients who underwent preprocedural CT (CT-guided ASA group, n = 11) were compared with patients who underwent ASA without CT (traditional ASA group, n = 19)...

The benefit of optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) is unclear. We aimed to assess the incremental value of adding OCT to coronary angiography in PCI by meta-analytic technique. We searched PubMed, EMBASE, Cochrane, Scopus and relevant references for randomized studies (inception through January 5, 2018 without language restrictions) and performed meta-analysis using random effects model. Major adverse cardiac events (MACE), all-cause mortality, myocardial infarction, target vessel revascularization, stent thrombosis, fluoroscopic time, contrast volume, and procedural side effects were the measured outcomes...

Increasing the urine flow rate (UFR) reduces the toxic effect of contrast media. Use of the RenalGuard system enables the achievement of a high UFR by maintaining intravascular volume and prevents the development of contrast-induced acute kidney injury (CI-AKI). However, the efficacy and safety of RenalGuard system have not yet been evaluated in Japan. This multicenter prospective study evaluated the efficacy and safety of the RenalGuard therapy in preventing CI-AKI development in 60 Japanese patients with renal dysfunction [estimated glomerular filtration rate (eGFR) < 45 mL/min/1...

Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a powerful device for treatment of patients with life-threatening heart failure. Although bleeding is often associated with VA ECMO and sometimes results in a fatal outcome, its precise causes remain unknown. On the other hand, excessive high shear stress in the cardiovascular system causes acquired von Willebrand syndrome (aVWS), characterized by loss of von Willebrand factor (vWF) large multimers. vWF large multimers of five consecutive patients treated with VA ECMO were quantitatively evaluated using the vWF large multimer indices, defined as the ratio of the large multimer ratio of a patient to that of a healthy subject analyzed simultaneously...

The mechanism of how angiographic results following paclitaxel-coated balloon (PCB) treatment for small vessel disease affect patient outcome remains unknown. In the present study, we aimed to investigate the correlation between coronary dissection immediately after PCB angioplasty and midterm outcome. From March 2014 to March 2017, 171 consecutive patients with 228 native coronary artery lesions who received PCB angioplasty at a single center were enrolled retrospectively. Lesions with a reference vessel diameter > 2...

Catheter angioplasty or angiography via the distal access point of the radial artery (dRA), located at the anatomical snuff box, is a less invasive strategy for coronary intervention attracting considerable attention. Determining the diameter of the dRA is necessary to minimize the risk of artery occlusion and safely perform catheter intervention. This was a retrospective observational study including patients who underwent coronary angiography or coronary intervention at Aomori Kyoritsu Hospital, Aomori, Japan, between February 2018 and August 2018...
