BACKGROUND In long-term follow-up after drug-eluting stents (DES) implantation, late target lesion revascularization (TLR) is occasionally required. However, the incidence and predictors for late TLR with DES have not been fully investigated. METHODS AND RESULTS Between August 2004 and March 2005, 249 consecutive patients underwent percutaneous coronary(More)
OBJECTIVE To determine the features of alexia or agraphia with a left angular or supramarginal gyrus lesion. METHODS We assessed the reading and writing abilities of three patients using kanji (Japanese morphograms) and kana (Japanese syllabograms). RESULTS Patient 1 showed kana alexia and kanji agraphia following a hemorrhage in the left angular gyrus(More)
The SYNTAX score stratifies risk among drug-eluting stent-treated patients and is based on lesion characteristics alone. The Clinical SYNTAX Score (CSS) combines the SYNTAX score with age, ejection fraction, and creatinine clearance. We assessed its ability to stratify long-term outcomes in sirolimus-eluting stents (SES)-treated patients. Between August(More)
BACKGROUND Limited data exist regarding transcatheter mitral valve replacement (TMVR) for patients with failed mitral valve replacement and repair. OBJECTIVES This study sought to evaluate the outcomes of TMVR in patients with failed mitral bioprosthetic valves (valve-in-valve [ViV]) and annuloplasty rings (valve-in-ring [ViR]). METHODS From the TMVR(More)
Aims To assess the incidence, management and long-term outcomes of transcatheter heart valve thrombosis (THVT). Methods and results Between August 2007 and February 2016, 1396 patients were included in the Bern TAVI Registry and prospectively followed-up through echocardiographic and clinical evaluation. THVT was suspected in case of: (i) a mean(More)
BACKGROUND The impact of baseline renal dysfunction on early and late clinical outcomes after transcatheter aortic valve implantation (TAVI) remains to be defined. METHODS 927 patients included in the prospective Bern TAVI registry were classified on the basis of the baseline estimated glomerular filtration rate (eGFR), as having none or mild (eGFR(More)
Previous studies reporting that statin increases coronary artery calcium (CAC) were conducted exclusively on patients with statin as a prevention, regardless of the presence or absence of dyslipidemia. The impact of sex on CAC has not been fully evaluated. We aimed to determine the association of dyslipidemia and sex with CAC using 320-row multi-detector(More)
The aim of this study was to address 7-year clinical outcomes and impact of prolonged dual antiplatelet therapy (DAPT) after coronary stenting in hemodialysis patients. Our study included 123 consecutive hemodialysis patients who had undergone percutaneous coronary intervention with a drug-eluting stent (DES) or bare-metal stent (BMS) (DES: 64, BMS: 59) in(More)
OBJECTIVES The aim of this study was to examine the frequency, timing, and association of access-site and non-access-site bleeding with mortality in the setting of transcatheter aortic valve replacement (TAVR) during long-term follow-up. BACKGROUND Bleeding is frequent and associated with impaired prognosis in patients undergoing TAVR. It is currently(More)
