RESUMO
BACKGROUND: Accurate prediction of bacteremia is essential for guiding blood culture collection and optimal antibiotic treatment. Shaking chills, defined as a subjective chill sensation with objective body shivering, have been suggested as a potential predictor of bacteremia; however, conflicting findings exist. To address the evidence gap, we conducted a systematic review and meta-analysis of studies to assess the diagnostic accuracy of shaking chills for predicting bacteremia among adult patients. METHODS: We included studies reporting the diagnostic accuracy of shaking chills or chills for bacteremia. Adult patients with suspected bacteremia who underwent at least one set of blood cultures were included. Our main analysis focused on studies that assessed shaking chills. We searched these studies through CENTRAL, MEDLINE, Embase, the World Health Organization ICTRP Search Portal, and ClinicalTrials.gov. Study selection, data extraction, evaluation for risk of bias, and applicability using the QUADAS-2 tool were conducted by two independent investigators. We estimated a summary receiver operating characteristic curve and a summary point of sensitivity and specificity of the index tests, using a hierarchical model and the bivariate model, respectively. RESULTS: We identified 19 studies with a total of 14,641 patients in which the accuracy of shaking chills was evaluated. The pooled sensitivity and specificity of shaking chills were 0.37 (95% confidence interval [CI], 0.29 to 0.45) and 0.87 (95% CI, 0.83 to 0.90), respectively. Most studies had a low risk of bias in the index test domain and a high risk of bias and a high applicability concern in the patient-selection domain. CONCLUSIONS: Shaking chills are a highly specific but less sensitive predictor of bacteremia. Blood cultures and early initiation of antibiotics should be considered for patients with an episode of shaking chills; however, the absence of shaking chills must not lead to exclusion of bacteremia and early antibiotic treatment.

BACKGROUND: In the elderly people with unprotected left main distal bifurcation lesions (ULMD), percutaneous coronary intervention (PCI) is often selected as first choice treatment strategy because of perioperative high risk of coronary artery bypass graft surgery due to their large number of comorbidities. Also, some recent papers reported that geriatric nutritional risk index (GNRI) is also strongly associated with clinical outcomes after interventional procedures in elderly patients. OBJECTIVES: We assessed clinical outcomes after PCI for ULMD and the impact of GNRI in elderly patients. METHODS: We identified 669 non dialysis patients treated with current generation drug-eluting stent for ULMD from MITO registry. We divided the patients to the following 2 groups; elderly group (n = 240, age ≥75) and young group (n = 429, age <75). Additionally, we could calculate GNRI and divided elderly group into 2 group based on the median value of the GNRI. The primary endpoint was all-cause mortality. RESULTS: All-cause mortality was significantly higher in elderly group [adjusted hazard ratio (HR) 2.37; 95% confidence interval (CI), 1.40-4.02; p = 0.001]. All-cause mortality was significantly higher in low GNRI elderly group compared to other 2 groups (Adjusted HR of elderly with low GNRI: 3.56, 95%CI (1.77-7.14), p < 0.001). Cardiovascular mortality was comparable between two groups. TLR rate was significantly lower in elderly group (adjusted HR 0.57; 95% CI, 0.34-0.97; p = 0.035). CONCLUSIONS: The elderly had higher all-cause mortality after PCI for ULMD compared to young people. Especially, the elderly with low GNRI were extremely associated with poorer outcomes.

BACKGROUND: Limited data are available regarding clinical outcomes after percutaneous left atrial appendage closure using WATCHMAN FLX (WM-FLX) and WATCHMAN-2.5 (WM2.5) devices in Asian patients. METHODSâANDâRESULTS: Data of 1,464 consecutive patients (WM-FLX, n=909; WM2.5, n=555) were extracted from a Japanese multicenter registry, and clinical data were compared between the 2 groups. No in-hospital deaths, periprocedural stroke, or device embolization occurred. Procedural success was significantly higher in the WM-FLX than WM2.5 group (95.8% vs. 91.9%; P=0.002) owing to the lower incidence of periprocedural pericardial effusion (0.55% vs. 1.8%; P=0.021). No significant differences in all-cause death, postprocedural stroke, and device-related thrombus were observed between the 2 groups. However, the cumulative bleeding rate at 1 year was substantially lower in the WM-FLX group (7.8% vs. 16.4%; P<0.001). Landmark analysis of bleeding events highlighted lower bleeding rates in the WM-FLX than WM2.5 group within the first 6 months (6.4% vs. 14.8%; P<0.001), with comparable bleeding rates over the 6- to 12-month period (1.5% vs. 3.2%, respectively; P=0.065). CONCLUSIONS: This study demonstrated higher early safety and lower 1-year bleeding rates in the WM-FLX than WM2.5 group. The lower bleeding events with WM-FLX are likely due to multiple factors other than purely difference in devices, such as postprocedural drug regimen.

BACKGROUNDS: There are limited data on the clinical relevance of transvalvular flow rate (Qmean ) at rest (Qrest) and at peak stress (Qstress ) during dobutamine stress echocardiography (DSE) in patients with low-gradient severe aortic stenosis (LG-SAS). METHODS: We retrospectively analyzed the clinical data of patients with LG-SAS who underwent DSE. LG-SAS was defined as an aortic valve (AV) area index of < .6 cm2 /m2 and a mean AV pressure gradient (AVPG) of < 40 mm Hg. The primary endpoint included all-cause death and heart failure hospitalization. RESULTS: Of 100 patients (mean age 79.5 ± 7.3 years; men, 45.0%; resting left ventricular ejection fraction [LVEF] 52.1% ± 15.9%; resting stroke volume index 35.8 ± 7.7 mL/m2 ; Qrest 171.8 ± 34.9 mL/s), the primary endpoint occurred in 51 patients during a median follow-up of 2.84 (interquartile range 1.01-5.21) years. When the study patients were divided into three subgroups based on Qrest and Qstress , the multivariate analysis showed that Qrest < 200 mL/s and Qstress ≥200 mL/s (hazard ratio 3.844; 95% confidence interval 1.143-12.930; p = .030), as well as Qrest and Qstress < 200 mL/s (hazard ratio 9.444; 95% confidence interval 2.420-36.850; p = .001), were significantly associated with unfavorable outcomes with Qrest and Qstress ≥200 mL/s as a reference after adjusting for resting LVEF, resting mean AVPG, chronic kidney disease, New York Heart Association functional class III/IV, and AV replacement. CONCLUSIONS: Flow conditions based on the combination of Qrest and Qstress are helpful for risk stratification in LG-SAS patients.

Background: In secondary mitral regurgitation (SMR), effective regurgitant orifice area by the proximal isovelocity surface area method ( EROA PISA ) evaluation might cause an underestimation of regurgitant orifice area because of its ellipticity compared with vena contracta area (VCA). We aimed to reassess the SMR severity using VCA-related parameters and EROA PISA . Methods: The three-dimensional transesophageal echocardiography data of 128 patients with SMR were retrospectively analyzed; the following parameters were evaluated: EROA PISA , anteroposterior and mediolateral vena contracta widths (VCWs) of VCA (i.e., VCW AP and VCW ML ), VCW Average calculated as ( VCW AP + VCW ML )/2, and VCA Ellipse calculated as π × ( VCW AP /2) × ( VCW ML /2). Severe SMR was defined as ≥ 0.39 cm 2 . Results: The mean age of the patients was 77.0 ± 8.9 years, and 78 (60.9%) were males. Compared with EROA PISA (r = 0.801), VCW Average (r = 0.940) and VCA Ellipse (r = 0.980) were strongly correlated with VCA. On receiver-operating characteristic curve analysis, VCW Average and VCA Ellipse had C-statistics of 0.981 (95% confidence interval [CI], 0.963-1.000) and 0.985 (95% CI, 0.970-1.000), respectively; these were significantly higher than 0.910 (95% CI, 0.859-0.961) in EROA PISA (p = 0.007 and p = 0.003, respectively). The best cutoff values for severe SMR of VCW Average and VCA Ellipse were 0.78 cm and 0.42 cm 2 , respectively. The prevalence of severe SMR significantly increased with an increase in EROA PISA (38 of 88 [43.2%] patients with EROA PISA < 0.30 cm 2 , 21 of 24 [87.5%] patients with EROA PISA = 0.30-0.40 cm 2 , and 16 of 16 [100%] patients with EROA PISA ≥ 0.40 cm 2 [Cochran-Armitage test; p < 0.001]). Among patients with EROA PISA < 0.30 cm 2 , SMR severity based on VCA was accurately reclassified using VCW Average (McNemar's test; p = 0.505) and VCA Ellipse (p = 0.182). Conclusions: Among patients who had SMR with EROA PISA of < 0.30 cm 2 , suggestive of moderate or less SMR according to current guidelines, > 40% had discordantly severe SMR based on VCA. VCW Average and VCA Ellipse values were useful for identifying severe SMR based on VCA in these patients.
RESUMO
Optical coherence tomography (OCT) is recommended to be the most appropriate modality in assessing calcium thickness, however, it has limitations associated with infrared attenuation. Although coronary computed tomography angiography (CCTA) detects calcification, it has low resolution and hence not recommended to measure the calcium size. The aim of this study was to devise a simple algorithm to estimate calcium thickness based on the CCTA image. A total of 68 patients who had CCTA for suspected coronary artery disease and subsequently went on to have OCT were included in the study. 238 lesions of them divided into derivation and validation dataset at 2:1 ratio (47 patients with 159 lesions and 21 with 79, respectively) were analyzed. A new method was developed to estimate calcium thickness from the maximum CT density within the calcification and compared with calcium thickness measured by OCT. Maximum Calcium density and measured calcium-border CT density had a good correlation with a linear equation of y = 0.58x + 201 (r = 0.892, 95% CI 0.855-0.919, p < 0.001). The estimated calcium thickness derived from this equation showed strong agreement with measured calcium thickness in validation and derivation dataset (r2 = 0.481 and 0.527, 95% CI 0.609-0.842 and 0.497-0.782, p < 0.001 in both, respectively), more accurate than the estimation by full width at half maximum and inflection point method. In conclusion, this novel method provided the estimation of calcium thickness more accurately than conventional methods.

BACKGROUND: Transcatheter mitral valve repair with the MitraClip system has been established in selected high-risk patients. The MitraClip procedure results in a relatively large iatrogenic atrial septal defect (iASD). This study aimed to investigate the prevalence and clinical course of iASD requiring transcatheter closure following the MitraClip procedure.MethodsâandâResults: This study was conducted at all 59 institutions that perform transcatheter mitral valve repair with the MitraClip system in Japan. The data of patients on whom transcatheter iASD closure was performed were collected. Of the 2,722 patients who underwent the MitraClip procedure, 30 (1%) required transcatheter iASD closure. The maximum iASD size was 9±4 mm (range, 3-18 mm). The common clinical course of transcatheter iASD closure was hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt. Of the 30 patients, 22 (73%) required transcatheter closure within 24 h following the MitraClip procedure, including 12 with hypoxemia and 5 with right-sided heart failure complicated with cardiogenic shock. Of the 5 patients, 2 required mechanical circulatory support devices. Twenty-one patients immediately underwent transcatheter iASD closure, and hemodynamic deteriorations were resolved; however, 1 patient died without having undergone transcatheter closure. CONCLUSIONS: Transcatheter iASD closure was required in 1% of patients who underwent the MitraClip procedure. Many of these patients immediately underwent transcatheter iASD closure because of hypoxemia with right-to-left shunt or right-sided heart failure with left-to-right shunt.

BACKGROUND: Japanese patients undergoing transcatheter aortic valve replacement (TAVR) are often female and have a small body size, potentially impacting bleeding risk with antithrombotic therapy. Outcomes of direct oral anticoagulant use in these patients with atrial fibrillation (AF) need to be clarified.MethodsâandâResults: This prespecified analysis included Japanese patients from ENVISAGE-TAVI AF, a prospective, randomized, open-label, adjudicator-masked trial that compared treatment with edoxaban and vitamin K antagonists (VKAs) in patients with AF after TAVR. The primary efficacy and safety outcomes were net adverse clinical events (NACE; composite of all-cause death, myocardial infarction, ischemic stroke, systemic embolic event, valve thrombosis, and International Society on Thrombosis and Haemostasis [ISTH]-defined major bleeding) and ISTH-defined major bleeding, respectively. Intention-to-treat (ITT) and on-treatment analyses were performed. Overall, 159 Japanese patients were enrolled (edoxaban group: 82, VKA group: 77) and followed for on average 483 days. Mean patient age was 83.8 years; 52.2% were female. In the ITT analysis, NACE rates were 10.9%/year with edoxaban and 12.5%/year with VKA (hazard ratio [HR], 0.85; 95% confidence interval [CI], 0.38-1.90); major bleeding occurred in 8.9%/year and 7.3%/year, respectively (HR, 1.17; 95% CI, 0.45-3.05). In edoxaban- and VKA-treated patients, rates of ischemic stroke were 1.8%/year and 1.0%/year, respectively; fatal bleeding rates were 0.9%/year and 2.0 %/year. On-treatment results were similar to ITT. CONCLUSIONS: In Japanese patients with AF after successful TAVR, edoxaban and VKA treatment have similar safety and efficacy profiles.

PURPOSE: The purpose of this study was to investigate the impact of social isolation and loneliness on the overall survival and death at home in patients with lung cancer. METHODS: This prospective cohort study was conducted in a Japanese tertiary hospital. The enrollment period was from April 2018 to March 2020. Patients with pathologically diagnosed advanced lung cancer were included in this study. The primary outcome was overall survival, whereas the secondary outcome was death at home. The exposures were social isolation and loneliness. RESULTS: A total of 211 patients were enrolled and divided into two groups and further into quartiles according to their social isolation and loneliness level, respectively. The hazard ratios of social isolation were 1.65 (95% confidence interval; 1.12 to 2.44) and 1.87 (95% confidence interval; 1.15 to 3.03) in the univariate analysis, while 1.40 (95% confidence interval; 0.92 to 2.13) in the multivariate analysis with complete case and multiple imputation. The odds ratio of death at home with social isolation was 3.47 (95% confidence interval; 1.08 to 11.1) in the multivariate analysis with multiple imputation. Loneliness was not associated with overall survival or death at home. CONCLUSIONS: Our study suggests that social isolation may be related to overall survival and death at home among patients with advanced lung cancer. More attention should be given to such patients at the time of diagnosis.

Vascular inflammation, lipid metabolism, and thrombogenicity play a key role not only in atherogenesis but also in the development of acute coronary syndromes. Biomarkers associated with coronary high-risk plaques defined according to intravascular imaging have not been systematically studied. A total of 69 patients with coronary artery disease who underwent both optical coherence tomography and intravascular ultrasound imaging, and who provided blood specimens were included. Comprehensive biomarkers for inflammation, lipid, and coagulation were analyzed. Composite models sought biomarker patterns associated with thin-cap fibroatheroma (TCFA) and "high-risk plaques" (TCFA and large plaque burden). Two different composite models were developed for TCFA, based on the finding that high sensitivity C-reactive protein (hsCRP), plasminogen activator inhibitor-1, fibrinogen, IL-6, homocysteine and amyloid A levels were elevated, and high-density lipoprotein cholesterol (HDL) and bile acid levels were decreased in these patients. Both composite models were highly accurate for detecting patients with TCFA (area under curve [AUC]: 0.883 in model-A and 0.875 in model-B, both p < 0.001). In addition, creatinine, hsCRP, fibrinogen, tumor necrosis factor-α, IL-6, homocysteine, amyloid A, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques". Two composite models were highly accurate for detection of patients with "high-risk plaques" (AUC: 0.925 in model-A and 0.947 in model-B, both p < 0.001). Biomarkers useful for detection of patients with high-risk coronary plaques defined according to intravascular imaging have been identified. These biomarkers may be useful to risk stratify patients and to develop targeted therapy.Clinical Trial Registration https://www.umin.ac.jp/ctr/ , UMIN000041692. Biomarkers and high-risk plaques hsCRP, PAI-1, fibrinogen, IL-6, homocysteine, amyloid A, HDL, and bile acid were useful for detecting patients with TCFA. hsCRP, fibrinogen, IL-6, homocysteine, amyloid A, creatinine, TNFα, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques" (plaque which has both TCFA and large plaque burden). White arrowhead denotes TCFA. Red and green dashed lines denote lumen area and external elastic membrane area, respectively.

Objectives. The impact of chronic kidney disease (CKD) on clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main distal bifurcation lesions (ULMD) is not fully understood in current generation drug eluting stent (cDES) era. We assessed clinical outcomes after PCI using cDES for ULMD according to CKD severity based on estimated glomerular filtration rate (eGFR). Design. We identified 720 consecutive patients who underwent PCI using cDES for ULMD at three high volume centers between January 2005 and December 2015. We divided those patients to the following five groups according to eGFR. Each group was defined as follows: no CKD (60 mL/min/1.73 m2 ≤ eGFR), mild CKD (45 ≤ eGFR < 60 mL/min/1.73 m2), moderate CKD (30 ≤ eGFR < 45 mL/min/1.73 m2), severe CKD (15 ≤ eGFR < 30 mL/min/1.73 m2) and hemodialysis (HD). The primary endpoint was target lesion failure (TLF) at 3 years. TLF was defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI). Results. TLF occurred more frequently in severe CKD and HD group compared with other three groups. Conclusions. The patients who have severe CKD or are on HD, were extremely associated with worse clinical outcomes after PCI for ULMD even with cDES.

Although the simple single stenting rather than complex double stenting is recommended on percutaneous coronary intervention (PCI) for bifurcation lesions, double stenting cannot always be avoided. We investigated the impact of directional coronary atherectomy (DCA), followed by drug-coated balloon (DCB) treatment to reduce the number of stents and avoid complex stenting in PCI for bifurcation lesions and short-term patency. DCA treatment without stents was attempted for 27 bifurcation lesions in 25 patients, of those, 26 bifurcation lesions in 24 patients were successfully treated and 3-month follow-up angiography and optical coherence tomography (OCT) were performed. Sixteen lesions (59.3%) were related to left main trunk distal bifurcations, and 7 (25.9%) were true bifurcation lesions. Among the true bifurcation lesions, 4 lesions (57.1%) needed 1 stent, and the other 3 lesions (42.9%) needed no stents. Among the non-true bifurcation lesions, 1 lesion (5.0%) needed bailout stent and other lesions (95.0%) needed no stents. According to DCA followed by DCB treatment, the angiographic mean diameter stenosis improved from 65.5 ± 15.0% to 7.8 ± 9.8%, and the mean plaque area in intravascular ultrasound improved from 80.4 ± 10.5% to 39.0 ± 11.5%, respectively. Angiographic and OCT late lumen loss values were 0.2 ± 0.6 mm and 1.4 ± 1.9 mm, respectively. No patient had in-hospital major adverse cardiac events (MACE) and 3-month MACE. In conclusion, compared with standard provisional side branch stenting strategy, DCA followed by DCB treatment might reduce the number of stents, avoid complex stenting for major bifurcation lesions and provide good short-term outcomes.

BACKGROUND: Information on early to late-phase kidney damage in patients who underwent transcatheter aortic valve replacement (TAVR) is scarce. We aimed to identify the predictive factors for late kidney injury (LKI) at 1-year and patient prognosis beyond 1-year after TAVR. METHODS: We retrospectively reviewed 1,705 patients' data from the Japanese TAVR multicenter registry. Acute kidney injury (AKI) and LKI, defined as an increase of at least 0.3 mg/dL in creatinine level, a relative 50% decrease in kidney function from baseline to 48 hours and 1-year, were evaluated. The patients were categorized into the 4 groups as AKI-/LKI- (nâ¯=â¯1.362), AKI+/LKI- (nâ¯=â¯95), AKI-/LKI+ (nâ¯=â¯199), and AKI+/LKI+ (nâ¯=â¯46). RESULTS: The cumulative 3-year mortality rates were significantly increased across the four groups (12.5%, 15.8%, 24.6%, 25.8%, P < .001). Multivariate analysis revealed that chronic kidney disease, coronary artery disease, periprocedural AKI, and heart failure-related re-admission within 1-year were significantly associated with LKI. The Cox regression analysis revealed that AKI-/LKI+ and AKI+/LKI+ were independent predictors of increased late mortality beyond 1-year after TAVR (P = .001 and P = .01). CONCLUSIONS: LKI was influenced by adverse cardio-renal events and was associated with increased risks of late mortality beyond 1-year after TAVR.

PURPOSE: Little is known about the fall risk of older adults with overactive bladder, especially in the absence of urgency incontinence. We evaluated the impacts of overactive bladder with and without urgency incontinence (overactive bladder wet and overactive bladder dry) on the fall risk in older adults, and investigated the importance of overactive bladder as a predictor of falls by using tree based models. MATERIALS AND METHODS: This prospective cohort study included 630 community dwelling, independent older adults 75 years old or older who attended a health checkup in 2017 with a 1-year followup. The associations of overactive bladder dry and overactive bladder wet with a fall history, and future fall risk compared to no overactive bladder were assessed using logistic regression models. The contribution of overactive bladder as a predictor of falls was examined using a random forest and decision tree approach. RESULTS: Of the 577 analyzed participants (median age 79 years), 273 (47%) were men. The prevalence of overactive bladder dry and overactive bladder wet at baseline was 15% and 14%, respectively. Multivariable logistic regression analysis revealed that both overactive bladder dry and overactive bladder wet were associated with a higher likelihood of prior falls (adjusted ORs vs no overactive bladder 2.03 and 2.21, respectively; 95% CI 1.23-3.37 and 1.29-3.78, respectively). Among the 363 participants without a fall history, the adjusted ORs (95% CIs) of overactive bladder dry and overactive bladder wet for the occurrence of falls during the 1-year followup were 2.74 (1.19-6.29) and 1.35 (0.47-3.87), respectively. The tree based approach used for all participants showed that overactive bladder was an important predictor of falls in adults without a fall history, and the model had 83.6% accuracy and 81.8% AUC. CONCLUSIONS: Overactive bladder, even in the absence of urgency incontinence, is an important predictor of falls in older adults with a low absolute fall risk.

OBJECTIVES: This study evaluated the 5-years outcomes of intracoronary imaging-guided proximal optimization technique (POT) for percutaneous coronary intervention (PCI) in patients with unprotected left main distal bifurcation lesions (ULMD). BACKGROUND: The long-term effects of POT with intracoronary imaging guide in PCI for ULMD have been unclear. METHODS: Between January 2005 and December 2015, we identified 1832 consecutive patients who underwent DES implantation for ULM distal bifurcation lesions. Of them, 780 (56.1%) patients underwent POT with intravascular imaging guidance (optimal expansion group). Residual 611 (43.9%) patients did not undergo either POT or intravascular imaging or both (suboptimal expansion group). Analysis using propensity score adjustment was performed. The primary endpoint was target lesion failure (TLF) defined as a composite of cardiac death, target lesion revascularization (TLR), and myocardial infarction. RESULTS: TLF rate at 5 years was significantly lower in optimal expansion group than that in suboptimal expansion group [adjusted HR 0.65, 95% CI (0.48-0.87), p = 0.004]. Cardiac mortality was significantly lower in optimal expansion group than that in suboptimal expansion group [adjusted HR 0.46, 95% CI (0.27-0.79), p = 0.004]. The multivariable analysis identified POT with intravascular imaging guide [adjusted HR 0.65, 95% CI (0.48-0.87), p = 0.004] as an independent predictor of TLF. CONCLUSIONS: Intravascular imaging guided POT was strongly associated with the reduced risk of TLF at 5 years after PCI for ULMD, mainly driven by reducing cardiac mortality.

BACKGROUND: There are only little data available on the comparison of clinical outcomes between a early generation drug eluting stent (eDES) and a current generation drug eluting stent (cDES) for percutaneous coronary intervention (PCI) with double stent strategy (DSS) for unprotected distal left main disease (ULMD). METHODS: Between April 2005 and December 2015, we recruited 452 consecutive ULMD patients treated with DSS (eDES, 236 patients; cDES, 216 patients). In this study, eDES included Cipher, Taxus, and Endeavor and cDES included Ultimaster, Resolute family, Xience family, Promus family, Synergy, and Nobori. The primary endpoint was target lesion failure (TLF) defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI) during the median follow-up period of 1,809(IQR: 1,190-2,510) days. RESULTS: In entire population, the rate of overall TLR was significantly lower in cDES group than that in eDES group (adjusted HR 0.62, 95% CI 0.40-0.96, p = .032). The rate of TLR for the ostium of LCX was significantly lower in cDES group than that in eDES group (adjusted HR 0.63, 95% CI 0.39-0.99, p = .047). Cardiac mortality, the rate of TLR for LM-LAD, MI and definite/probable ST did not significantly differ between both groups. The results were preserved in the propensity adjusted population. CONCLUSIONS: cDES significantly improved the clinical outcomes in population treated with DSS mainly driven by the reduction of TLR for the ostium of LCX.

OBJECTIVES: We assessed the impact of pre-percutaneous coronary intervention (PCI) bifurcation angle change (BAC) on clinical outcomes. BACKGROUND: There are little available data about the impact of BAC in unprotected left main distal bifurcation lesions (ULMD) PCI. METHODS: We identified consecutive 300 patients with ULMD underwent complex stenting using drug-eluting stent in three high-volume centers (Tokyo and Milan). We measured the widest BA of ULMD at both end-diastole and end-systole before stenting with two-dimensional quantitative coronary angiographic assessment and calculated the BAC value as a difference of two BA value in each lesion. We divided them into small and large BAC group according to the median BAC value (7.2°). The primary endpoint was target lesion failure (TLF), which was defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction. RESULTS: TLF rate at 3-year was significantly higher in the large BAC group than in the small BAC group (adjusted hazard ratio [HR] 5.85; 95% confidence interval [CI], 3.40-10.1; p < .001). TLR rate for left main (LM) to left anterior descending artery (LAD) and ostial left circumflex artery (LCXos) at 3-year were significantly higher in large BAC group than in small BAC group (adjusted HR 5.91; 95% CI, 2.03-17.2; p = .001 and adjusted HR 10.6; 95% CI, 5.20-21.6; p < .001, respectively). CONCLUSIONS: A large BAC before stenting is strongly associated with adverse events after complex stenting for ULMD, mainly driven by repeat PCI for restenosis of the LCXos and of the LM-LAD.

OBJECTIVES: To identify the vulnerable diabetic cohort in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUNDS: Considerable controversy remains about whether specific cohort exists in which presence of diabetes mellitus (DM) carries adverse risk of mortality after TAVR. METHODS: Of the 2588 patients who were enrolled in the OCEAN-TAVI registry, 2526 patients with glycohemoglobin data were analyzed. The individuals were divided into DM and non-DM groups according to previous medical history of DM or using diabetic medicine, and increased HbA1c values (≥6.5%) at baseline. The primary endpoint of this study was 2-year all-cause mortality after TAVR. RESULTS: The follow up rate of clinical outcome at 1-year was 2514/2526 (99.5%) and median follow-up period was 22.5 months. DM group had 699 (27.7%) patients, in which 153 (21.9%) was diagnosed by increased HbA1c levels without previous medical history of DM. Kaplan-Meier curve of 2-year all-cause mortality presented significant difference between patients with and without DM (p = 0.029). In addition, patients with low-density lipoprotein cholesterol (LDL-C) levels > 100 mg/dl and left ventricular ejection fraction (LVEF) < 40% had great risk of mortality after TAVR (LDL-C: hazard ratio [HR] 1.82, p < 0.001; LVEF: HR 2.61, p = 0.002, respectively). CONCLUSIONS: Presence of DM was significantly associated with poor outcome after TAVR and adverse effect of DM was remarkable in patients with relatively higher LDL-C levels and reduced LVEF under 40%. These subtypes may need intensive control of cardiovascular risk factors, including DM, before and after TAVR.

OBJECTIVES: To confirm whether the rescue transcatheter heart valve in the transcatheter heart valve (THV-in-THV) procedure is effective and feasible, we aimed to assess the midterm outcomes following rescue THV-in-THV procedures. The trends in the usage of the rescue THV-in-THV procedure at the time of transcatheter aortic valve implantation (TAVI) have also been explored. BACKGROUND: Midterm outcomes of the rescue THV-in-THV procedure have been poorly defined, though it is popular as an effective method to bail-out some complications in TAVI. METHODS: We reviewed data from the Optimized transCathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation (OCEAN-TAVI) registry and compared the outcomes of TAVI with rescue THV-in-THV and TAVI without rescue THV-in-THV. We also examined the annual rates of rescue THV-in-THV procedures in all the TAVI procedures between 2013 and 2017. RESULTS: Among 2,588 patients who underwent TAVI, 26 patients have required rescue THV-in-THV for valve malposition (n = 23) or severe transvalvular regurgitation because of stuck THV leaflets (n = 3). Three cases needed an open conversion, and two died in the hospital. The rates of new permanent pacemaker implantation, acute kidney injury, and stroke were higher in the THV-in-THV group. A two-year cumulative survival and echocardiographic outcomes succeeding rescue THV-in-THV procedure were comparable to non-THV-in-THV cases. The rate of rescue THV-in-THV procedure lessened from 2.6% in 2013 to 0.6% in 2017. CONCLUSIONS: The rescue THV-in-THV procedure is an effective and feasible option for THV malpositioning and stuck valve. It has given a comparable survival and a stable valve function over midterm observation periods.

OBJECTIVES: Estimating 1-year life expectancy is an essential factor when evaluating appropriate indicators for transcatheter aortic valve replacement (TAVR). BACKGROUND: It is clinically useful in developing a reliable risk model for predicting 1-year mortality after TAVR. METHODS: We evaluated 2,588 patients who underwent TAVR using data from the Optimized CathEter vAlvular iNtervention (OCEAN) Japanese multicenter registry from October 2013 to May 2017. The 1-year clinical follow-up was achieved by 99.5% of the entire population (n = 2,575). Patients were randomly divided into two cohorts: the derivation cohort (n = 1,931, 75% of the study population) and the validation cohort (n = 644). Considerable clinical variables including individual patient's comorbidities and frailty markers were used for predicting 1-year mortality following TAVR. RESULTS: In the derivation cohort, a multivariate logistic regression analysis demonstrated that sex, body mass index, Clinical Frailty Scale, atrial fibrillation, peripheral artery disease, prior cardiac surgery, serum albumin, renal function as estimated glomerular filtration rate, and presence of pulmonary disease were independent predictors of 1-year mortality after TAVR. Using these variables, a risk prediction model was constructed to estimate the 1-year risk of mortality after TAVR. In the validation cohort, the risk prediction model revealed high discrimination ability and acceptable calibration with area under the curve of 0.763 (95% confidence interval, 0.728-0.795, p < .001) in the receiver operating characteristics curve analysis and a Hosmer-Lemeshow χ2 statistic of 5.96 (p = .65). CONCLUSIONS: This risk prediction model for 1-year mortality may be a reliable tool for risk stratification and identification of adequate candidates in patients undergoing TAVR.
