The semiquantitative Clinical Frailty Scale (CFS) is a simple tool to assess patients' frailty and has been shown correlate with mortality in elderly patients even when evaluated by nongeriatricians. aim of the current study was determine prognostic value CFS who underwent transcatheter aortic valve replacement.We utilized OCEAN (Optimized Catheter Valvular Intervention) Japanese multicenter registry review data 1215 replacement. Patients were categorized into 5 groups based on stages: 1-3,...
Gait speed reflects an important factor of frailty and is associated with increased risk late mortality in patients cardiac disease. This study sought to assess the prognostic value gait elderly who underwent transcatheter aortic valve replacement.We investigated 5-m or 15-feet (m/sec) 1256 implantation using data from OCEAN-TAVI Japanese multicenter registry (Optimized Catheter Valvular Intervention-Transcatheter Aortic Valve Implantation). Baseline characteristics, procedural outcomes,...
Favourable results have been reported for monitored anaesthesia care that includes local and conscious sedation [minimalist approach (MA)] transfemoral transcatheter aortic valve replacement (TAVR). However, the efficacy of MA is still controversial in Japan. We describe our experience from a Japanese multicentre registry. Between October 2013 April 2016, 1215 consecutive patients with symptomatic, severe stenosis undergoing TAVR self-expandable or balloon-expandable valves were...
Objectives This study aimed to assess the feasibility of percutaneous arterial access site closure after transfemoral transcatheter aortic valve implantation (TF‐TAVI) using single versus double Perclose ProGlide devices. Backgrounds Although suturing with preclose technique has been widely adopted during TF‐TAVI, optimal vascular strategy is still under debate. Methods Data from 279 patients who underwent obtained Optimized CathEter vAlvular iNtervention (OCEAN‐TAVI) Japanese multicenter...
Although coronary vasospasm (CVS) would be one of the major causes out-of-hospital cardiac arrest (OHCA), characteristics patients with caused by CVS have not been clarified.In study 1, 1,000 consecutive OHCA were retrospectively categorized based on cause OHCA, and prevalence was elucidated. In 2, 138 divided into 2 groups: (arrest-CVS, n=12) without (non-arrest-CVS, n=126). 589 had cardiovascular disease 121 successfully resuscitated. Among resuscitated patients, 9 OHCA. incidence events...
Abstract Aims Plasma volume status (PVS) is recognized as a marker of systemic congestion, but its clinical utility in patients with mitral regurgitation (MR) undergoing transcatheter edge‐to‐edge valve repair (M‐TEER) has not been well established. This study aimed to evaluate the prognostic significance PVS these patients. Methods and results Data from 3763 who underwent M‐TEER were analysed Japanese multicentre registry. Patients classified into functional MR (FMR) degenerative (DMR)...
Abstract Objectives Estimating 1‐year life expectancy is an essential factor when evaluating appropriate indicators for transcatheter aortic valve replacement (TAVR). Background It clinically useful in developing a reliable risk model predicting mortality after TAVR. Methods We evaluated 2,588 patients who underwent TAVR using data from the Optimized CathEter vAlvular iNtervention (OCEAN) Japanese multicenter registry October 2013 to May 2017. The clinical follow‐up was achieved by 99.5% of...
There are no standardized criteria for measuring patients' frailty. We examined prognosis based on four frailty markers [serum albumin level, grip strength, gait speed, and clinical scale (CFS)] in patients who underwent transcatheter aortic valve replacement (TAVR) between October 2013 April 2016 were recorded the Optimized CathEter vAlvular iNtervention (OCEAN) Japanese multicenter registry. Serum level was assessed by dividing into two groups: hypoalbuminemia or non-hypoalbuminemia...
Background Although transcatheter aortic valve replacement ( TAVR ) is the least invasive treatment for patients with symptomatic stenosis, some hesitate to undergo procedure. We investigated clinical impact of delay after patient refusal . Methods and Results used Japanese OCEAN (Optimized Catheter valvular intervention) regsitry data 1542 who underwent Refusal was defined as at 1 time informed consent. Patients were separated into 2 groups: (28/1542, 1.8%) non-refusal (1514/1542, 98.2%)....
Data regarding the incidence, predictive factors, and clinical outcomes of post-transcatheter aortic valve replacement (TAVR) bleeding is limited in Asian cohort.This study sought to assess predictors prognostic impact post-TAVR late bleeding.This used Japanese multicenter registry data analyze 2,518 patients (mean age: 84.3 ± 5.2 years) who underwent TAVR. Late was defined as any postdischarge events after Baseline characteristics, including death rehospitalization were assessed with...
Abstract Aims This study investigated the prognostic value of plasma volume status (PVS) in patients who underwent transcatheter aortic valve replacement (TAVR). Methods and results Plasma was calculated 2588 TAVR using data from Japanese multicentre registry. All‐cause mortality heart failure hospitalization (HFH) within 2 years were compared among PVS quartiles (Q1, < 5.5%; Q2, 5.5–13.5%; Q3, 13.5–21.0%; Q4, ≥ 21.0%). Subgroups stratified by cut‐off combined with New York Heart...
Contrast-induced nephropathy (CIN) is considered to result from intrarenal vasoconstriction, and occurs more frequently in impaired than normal kidneys. It was hypothesized that iodinated contrast media would markedly change renal blood flow vascular resistance functionally Thirty-six patients were enrolled (32 men; mean age, 75.3 ± 7.6 years) undergoing diagnostic coronary angiography divided into two groups based on the presence of chronic kidney disease (CKD), defined as an estimated...
Abstract Objective This study aimed to assess the effect of chronic steroid use on periprocedural complications and clinical outcomes after transcatheter aortic valve replacement (TAVR). Background Chronic increases risk mortality during surgery. Methods We investigated 1,313 consecutive patients with stenosis who underwent transfemoral (TF)‐TAVR using data from a Japanese multicenter registry. The baseline characteristics, including vascular (VCs), access route related VCs, were compared...
The Direct Oral Anticoagulant (DOAC) Score can predict bleeding risk in patients with atrial fibrillation taking DOACs; however, it lacks external validation. Therefore, this study aimed to assess the association between DOAC and events who underwent transcatheter aortic valve replacement.
