RESUMO

Importance: The characteristics and treatment strategies of atrial functional mitral regurgitation (AFMR) are poorly understood. Objective: To investigate the prevalence, clinical characteristics, and outcomes of mitral valve (MV) surgery in AFMR. Design, Setting, and Participants: This retrospective cohort study, called the Real-World Observational Study for Investigating the Prevalence and Therapeutic Options for Atrial Functional Mitral Regurgitation (REVEAL-AFMR), was conducted across 26 Japanese centers (17 university hospitals, 1 national center, 3 public hospitals, and 5 private hospitals). All transthoracic echocardiography procedures performed from January 1 to December 31, 2019, were reviewed to enroll adult patients (aged ≥20 years) with moderate or severe AFMR, defined by preserved left ventricular function, a dilated left atrium, and an absence of degenerative valvular changes. Data were analyzed from May 8, 2023, to May 16, 2024. Exposures: Mitral valve surgery, with or without tricuspid valve intervention. Main Outcomes and Measures: The primary composite outcome included heart failure hospitalization and all-cause mortality. Results: In 177 235 patients who underwent echocardiography, 8867 had moderate or severe MR. Within this group, 1007 (11.4%) were diagnosed with AFMR (mean [SD] age, 77.8 [9.5] years; 55.7% female), of whom 807 (80.1%) had atrial fibrillation. Of these patients, 113 underwent MV surgery, with 92 (81.4%) receiving concurrent tricuspid valve surgery. Patients who underwent surgery were younger but had more severe MR (57.5% [n = 65] vs 9.4% [n = 84]; P < .001), a larger mean (SD) left atrial volume index (152.5 [97.8] mL/m2 vs 87.7 [53.1] mL/m2; P < .001), and a higher prevalence of heart failure (according to the New York Heart Association class III [marked limitation of physical activity] or class IV [symptoms of heart failure at rest], 26.5% [n = 30] vs 9.3% [n = 83]; P < .001) than those who remained under medical therapy. During a median follow-up of 1050 days (IQR, 741-1188 days), 286 patients (28.4%) experienced the primary outcome. Despite a more severe disease status, only the surgical group showed a decrease in natriuretic peptide levels at follow-up and had a significantly lower rate of the primary outcome (3-year event rates were 18.3% vs 33.3%; log-rank, P = .03). Statistical adjustments did not alter these findings. Conclusions and Relevance: The findings of this cohort study suggest that in patients with AFMR, who were typically older and predominantly had atrial fibrillation, MV surgery was associated with lower rates of adverse clinical outcomes. Future studies are warranted to investigate a possible causal relationship to better regulate cardiovascular medicine.

RESUMO

Hypertrophic cardiomyopathy (HCM) is a genetic disorder in which left ventricular outflow tract obstruction critically affects symptoms and prognosis. Traditionally, left ventricular outflow tract obstruction was primarily attributed to septal hypertrophy with systolic anterior motion of the mitral valve. However, recent evidence highlights significant contributions from the mitral valve and papillary muscle anomalies, as well as an apical-basal muscle bundle observed in HCM patients. Accurate morphological assessment is essential when considering septal reduction therapy. While transesophageal echocardiography and cardiac magnetic resonance are recommended for assessing the anomalous structures, four-dimensional computed tomography offers superior spatial resolution and multiplanar reconstruction capabilities. These features enable the evaluation of details of the morphological anomalies, such as the apical-basal muscle band, papillary muscle anomalies, subaortic stenosis, and right ventricular outflow tract obstruction. Based on the detailed assessment of these morphological features, four-dimensional computed tomography has been utilized for planning of surgical correction in a comprehensive HCM center. This approach facilitates the intervention strategies and may improve outcomes in septal reduction therapy for obstructive HCM.

RESUMO

Although there are no podiatrists in 85% of countries worldwide, how diabetic foot is managed in those countries is still unknown. We sought to identify the health professionals involved in diabetic foot and their tasks in Japan, where no podiatrists exist. This cross-sectional study used the Japanese Nationwide Survey on Foot Ulcer Management dataset, consisting of 249 medical doctors and 680 allied health professionals. The types of health professionals involved in the diabetic foot were identified, and the tasks performed by each professional were compared within subgroups (medical doctors and allied health professionals). We found that the primary medical doctors involved in diabetic foot care in Japan were plastic surgeons (33.5%), dermatologists (21%), cardiovascular/vascular surgeons (15.2%), and cardiologists (12.1%). Nurses were the main allied health professionals (80%), and the rest consisted of prosthetists/orthotists (7.6%), physical/occupational therapists (5.9%), and clinical engineering technologists (3.6%). Medical doctors performed tasks related to their specialties significantly more than others (p < 0.001); however, they also engaged in tasks outside of their specialty, such as plastic surgeons performing preventive foot care (72%). Among allied health professionals, clinical engineering technologists performed more vascular assessments (p < 0.001), and half were engaged in wound management, preventive foot care, and self-foot care education. In conclusion, the type and proportion of health professionals in our study differed from those in countries with podiatrists, and many performed tasks outside their specialties. This is the first nationwide cross-sectional study of diabetic foot care in a country without podiatrists and is unique in examining multiple specialists/professionals in one study.

RESUMO

Low body weight and advanced age are reported to be among the best predictors of osteoporosis, and osteoporosis self-assessment tool (OST) values are calculated using a simple formula to identify postmenopausal women at increased risk of osteoporosis. In our recent study, we demonstrated an association between fractures and poor outcomes in postmenopausal women following transcatheter aortic valve replacement (TAVR). In this study, we aimed to investigate the osteoporotic risk in women with severe aortic stenosis and determined whether an OST could predict all-cause mortality following TAVR. The study population comprised 619 women who underwent TAVR. Compared to a quarter of patients with diagnosis of osteoporosis, 92.4% of participants were at high risk of osteoporosis based on OST criteria. When divided into tertiles based on OST values, patients in tertile 1 (lowest OST) displayed increased frailty, a higher incidence of multiple fractures, and greater Society of Thoracic Surgeons scores. Estimated all-cause mortality survival rates 3 years post-TAVR were 84.2 ± 3.0%, 89.5 ± 2.6%, and 96.9 ± 1.7% for OST tertiles 1, 2, and 3, respectively (p = 0.001). Multivariate analysis showed that the OST tertile 3 was associated with decreased risk of all-cause mortality compared with OST tertile 1 as the referent. Notably, a history of osteoporosis was not associated with all-cause mortality. Patients with high osteoporotic risk are highly prevalent among those with aortic stenosis according to the OST criteria. OST value is a useful marker for predicting all-cause mortality in patients undergoing TAVR.

RESUMO

BACKGROUND: When frailty is considered in patient selection, better outcomes are achieved in transcatheter aortic valve replacement (TAVR) procedures. This study investigated whether patient photographs could be utilized to qualitatively assess patient frailty and independently predict poor outcomes following TAVR. METHODS: This study included 1345 patients with severe aortic stenosis who underwent TAVR at the Sakakibara Heart Institute, Japan, between 2013 and 2022. Patient photographs were taken prior to the initial outpatient clinic examination or at discharge in case the patient's first visit was unplanned admission. Frailty was assessed from patient photographs using a four-point photographic frailty scale; 1 (non-frail), 2 (vulnerable), 3 (mild frail), and 4 (frail). Photographic frailty scale of 3 and 4 were defined as high. The primary endpoint was all-cause mortality following TAVR. RESULTS: Seven hundred ninety-six patients who had their facial photographs taken within six months before the TAVR procedure were analyzed. Patients with a higher photographic frailty scale belonged to New York Heart Association classes III/IV, and had higher Society of Thoracic Surgeons scores, higher incidence of wheelchair usage, lower hemoglobin, and smaller aortic valve areas. According to the frailty assessment, patients with a higher photographic frailty scale exhibited slower performance in the 5-m walk test, reduced hand grip strength, more severe dementia, had a higher clinical frailty scale, and lower serum albumin level. Multivariable Cox regression analysis revealed that the high photographic frailty scale was independently associated with all-cause mortality (adjusted hazard ratio 1.62, 95 % confidence interval 1.12-2.33, p = 0.010). Kaplan-Meier analysis indicated that patients with high photographic frailty scale had higher all-cause mortality rates compared to those with low scale (log-rank p = 0.011). CONCLUSIONS: Patient registration photographs can be used to obtain qualitative assessments of frailty in severe aortic stenosis cases, and such assessments can independently predict poor outcomes following TAVR.

RESUMO

There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins. We examined this relationship by combined retrospective analyses of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was analyzed for the effects of concomitant use of one or more nephrotoxins on VAN and the types of combinations of nephrotoxins that exacerbate VAN. Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ≥2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN.

RESUMO

Background Prognostic implications of transcatheter aortic valve implantation (TAVI) in low-gradient (LG) aortic stenosis (AS) remain controversial. The authors hypothesized that differences in cardiac functional recovery may solve this ongoing controversy. The aim was to evaluate clinical outcomes and the response of left ventricular (LV) function following TAVI in patients with LG AS. Methods and Results This multicenter retrospective study included 1742 patients with severe AS undergoing TAVI between January 2015 and March 2019. Patients were subdivided into low-flow (LF) LG, normal-flow (NF) LG, LF high-gradient, and NF high-gradient AS groups according to the mean gradient of the aortic valve (LG <40 mm Hg) and LV stroke volume index (LF <35 mL/m2). Outcomes and changes in echocardiographic parameters after TAVI were compared between the groups. A total of 227 patients (13%) had reduced ejection fraction, and 486 patients (28%) had LG AS (LF-LG 143 [8%]; NF-LG 343 [20%]). During a median follow-up period of 747 days, 301 patients experienced a composite end point of cardiovascular death and rehospitalization for cardiovascular events, which was higher in the LF-LG and NF-LG groups than in the high-gradient groups. LG AS was independently associated with the primary outcome (hazard ratio, 1.69; P<0.001). Among 1239 patients with follow-up echocardiography, LG AS showed less improvement in the LV mass index and LV end-diastolic volume compared with high-gradient AS after 1 year, while LV recovery was similar between the LF AS and NF AS groups. Conclusions LG AS was associated with poorer outcomes and LV recovery, regardless of flow status after TAVI. Careful evaluation of AS severity may be required in LG AS to provide TAVI within the appropriate time and advanced care afterward.

RESUMO

Direct, transition metal-free B(dan)-installation into organic frameworks has been developed. Heteroaryl-H bonds were transformable into the respective heteroaryl-B(dan) bonds through deprotonation. The resulting heteroaryl-B(dan) compounds, which are otherwise difficult to access, can undergo the direct Suzuki-Miyaura coupling. The method was demonstrated to apply to a silicon nucleophile, giving Lewis acidity-diminished stable silyl-B(dan) and -B(aam) in one pot.

RESUMO

BACKGROUND: The new sizing options of the MitraClip system (Abbott Vascular, Abbott Park, IL, USA) with extended clip arms were recently developed. Its applicability and effectiveness for ventricular functional mitral regurgitation (VFMR) are yet to be investigated. METHODS: We retrospectively reviewed consecutive patients with symptomatic VFMR who underwent transcatheter edge-to-edge repair between 2018 and 2022 at the Sakakibara Heart Institute. Pre- and post-procedural mitral valve morphologies were assessed using three-dimensional transesophageal echocardiography. RESULTS: In a total of 104 VFMR patients, the posterior mitral leaflet length was 12.8 ±â€¯2.8 mm and 92 % was indicative of the extended arm (≥9 mm). Although baseline VFMR was more severe in the patients treated with the extended arms (n = 35, XT group) than the patients treated with the standard arms (n = 69, NT group), the decrease in VFMR was greater in the XT group (delta three-dimensional vena contracta area - 43 ±â€¯33 mm2 vs. -31 ±â€¯22 mm2, p = 0.030) and residual VFMR was similar between the groups, with a significantly greater reduction in the mitral annulus anterior-posterior diameter (-4.9 ±â€¯2.2 mm vs -3.1 ±â€¯2.1 mm, p < 0.001) and mitral annulus area in the XT group. The use of extended arms was independently associated with shorter procedure time (81 ±â€¯26 min vs 108 ±â€¯41 min) after adjustment for device generation and the number of clips (p = 0.017). CONCLUSIONS: Most VFMR patients had enough leaflet lengths for transcatheter edge-to-edge repair using the MitraClip with the extended arms, which was associated with shorter procedure time and a greater decrease in the mitral annular size.

RESUMO

Platypnea-orthodeoxia syndrome (POS) is a rare disease characterized by dyspnea and hypoxemia in orthostatism that improves in the recumbent position. We herein report an 81-year-old woman with dyspnea in the upright position following thoracic vertebral compression fractures. After the patient's daughter brought a recording showing decreasing SpO2 (peripheral capillary oxygen saturation) in the upright position as measured by a portable pulse oximeter outside the hospital, a small atrial septal defect (ASD) was detected. A contrast echocardiogram and four-dimensional flow magnetic resonance imaging demonstrated a right-to-left shunt. The patient's symptoms dramatically improved after percutaneous ASD closure. In conclusion, such new technologies are useful for diagnosing POS.

RESUMO

There has been growing concern in worsening survival and renal outcomes following vancomycin-associated nephrotoxicity (VAN) onset, but the factors associated with these phenomena remain unclear. To examine these factors, we performed a retrospective study combining the analysis of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was used to evaluate the relationship between VAN and mortality using odds ratios (ORs) and 95% confidence intervals (CIs). Next, electronic medical records (EMRs) were examined in a more robust cohort for evaluation of the association between renal outcomes and worsening survival using Cox proportional hazards regression models. FAERS analysis revealed a significant correlation between VAN occurrence and increased mortality (OR: 1.30; 95% CI: 1.17-1.46). EMR analysis showed that non-recovery of VAN was associated with increased hospital mortality (hazard ratio [HR]: 4.05; 95% CI: 2.42-6.77) and 1-year mortality (HR: 3.03, 95% CI: 1.98-4.64). The HR for VAN recovery was lower for patients with acute kidney injury (AKI) stage ≥2 (HR: 0.09; 95% CI: 0.02-0.40). Thus, worsening survival outcomes were associated with non-recovery of VAN, whereby AKI stage ≥2 was a significant risk factor. Progression to severe VAN should be prevented for better survival outcomes.

RESUMO

Duchenne muscular dystrophy (DMD) is a congenital X-linked muscular dystrophy, and cardiomyopathy typically develops in the second decade of life. In those patients with severe heart failure, the use of mechanical circulatory support is considered one of the treatment options, however, the decision to implant the assist device should be made after gauging the inherent risks and potential benefits. Transcatheter mitral valve repair (TMVr) is performed in adults with heart failure due to severe mitral regurgitation (MR) refractory to guideline-directed medical therapies. Data on MitraClip-based treatment (Abbott Vascular, Menlo Park, CA, USA) of young patients with cardiomyopathy-associated severe heart failure remain limited. We present the first report on the safety and effectiveness of TMVr with the MitraClip in an 18-year-old man with DMD and severe MR who was at a prohibitive risk for mitral valve surgery or left ventricular assist device therapy due to comorbidities. He was discharged without complications and, is now asymptomatic at one year after TMVr. Learning objective: Readers will be able to:Understand the mechanism of mitral regurgitationUnderstand the less invasiveness and usefulness of this procedure.Discuss the indication of transcatheter mitral valve repair in young patients with severe heart failure.

RESUMO

A new dimethyl(phenyl)silylborane having a naphthalene-1,8-diaminato (dan) substituent on the boron center, PhMe2Si-B(dan), was synthesized. Owing to the diminished boron Lewis acidity, it is highly stable toward air. Synthetic application of the silylborane to catalytic silylboration and silylation of alkynes is also described.

RESUMO

BACKGROUND: Despite advances in technology and technique, a certain proportion of patients experience non-cardiovascular (CV) readmissions after transcatheter aortic valve replacement (TAVR). However, the actual burden and details of non-CV readmission remain uncertain. METHODS: The Japan-Transcatheter Valve Therapies (J-TVT) registry is a representative nationwide registry, and mandates complete data entry, including 1-year outcomes, for patients undergoing TAVR in Japan. We analyzed the non-CV adverse events (AEs) requiring readmission after the index TAVR procedure between 2013 and 2018. RESULTS: A total of 14,472 patients were analyzed (68.8% of women with median age of 85 years). Overall, 367 patients (2.5%) and 1050 patients (7.2%) had non-CV readmission at 30 days and 1 year, respectively. The most frequent non-CV AEs were related to respiratory (24.0%) and gastrointestinal disease (19.3%). Specifically, 79.0% of all respiratory AEs were pneumonia (infectious, interstitial, or aspiration). Of the gastrointestinal AEs, 22.1% were malignancies, and 18.5% were non-procedural-related bleeding. Age ≥90 years, male sex, body mass index <20 kg/m2, New York Heart Association functional class III/IV, atrial fibrillation/flutter, malignancy, chronic obstructive pulmonary disease, dialysis, hemoglobin level, albumin level, creatinine level, and non-transfemoral approach were independent predictors of non-CV readmission. CONCLUSIONS: In this analysis of the nationwide registry of patients undergoing TAVR, rate of non-CV readmission at 30 days and 1 year, particularly those related to respiratory and gastrointestinal conditions, were lower than those previously reported. However, caution is still needed when performing TAVR on patients susceptible to these conditions.

RESUMO

Information regarding fracture in patients with transcatheter aortic valve replacement (TAVR) is limited. We investigated the prevalence and impact of fracture in patients with severe aortic stenosis who had undergone TAVR. Of 913 consecutive patients with symptomatic, severe aortic stenosis who underwent TAVR at the Sakakibara Heart Institute between October 2013 and April 2020, 633 women were enrolled. The primary endpoint was all-cause mortality following TAVR. Patients with a history of fracture displayed smaller body mass indices, increased frailty, a higher prevalence of osteoporosis, and stroke history. Notably, 61.7% of patients with a history of fracture reported to have not taken any osteoporosis medications. Estimated all-cause mortality survival rates post-TAVR were significantly lower in patients with fractures than those without fractures. In the multivariate analysis, history of fracture was independently associated with all-cause mortality following TAVR. Furthermore, fracture prevalence was significantly greater in those who had a higher clinical frailty scale score were slower in the 5-m walk test, had more severe dementia as per the revised Hasegawa dementia scale, and performed poorly in the hand grip strength test. History of fracture was an independent predictor for all-cause mortality in patients undergoing TAVR. In addition, our study demonstrated that osteoporotic fracture may be under-treated in this population. History of fracture may be one of the phenotypes of frailty given its significant relationship with frailty markers in this population.

RESUMO

PURPOSE: Inflammation after stent graft surgery is known as postimplantation syndrome (PIS) and it causes leukocytosis. However, we have experienced leukopenia in the very early postoperative phase of endovascular surgery at our institution. We investigated leukopenia, an under-recognized phenomenon that occurred after transcatheter aortic valve implantation (TAVI), endovascular aortic repair (EVAR), and thoracic endovascular aortic repair (TEVAR). METHODS: Records of patients who underwent TAVI, EVAR, and TEVAR between March 2018 and February 2019 were retrospectively reviewed. Primary outcomes were the decline rate of white blood cell count (DR-WBC) in the immediate postoperative period and its differences among surgical procedures. The secondary endpoint was the relationship between DR-WBC and infectious complications. Furthermore, the incidence of PIS and its differences among the procedures and associations with DR-WBC were evaluated. RESULTS: A total of 108 patients (TAVI 41, EVAR 37, TEVAR 30) were included. DR-WBC immediately after surgery was higher in the TAVI group when compared with other groups (TAVI, 43.1 ± 22.6%; EVAR, 27.6 ± 17.3%; TEVAR, 25.4 ± 27.4%; P < 0.01). DR-WBC was not significantly different regardless of postoperative infection (P = 0.45) or PIS (P = 0.62). The incidence rate of PIS was higher in the EVAR group compared with the TAVI group, and was not associated with DR-WBC. CONCLUSIONS: Leukopenia was a common phenomenon immediately after endovascular surgery, especially TAVI. It resolved a day after surgery and was not associated with PIS or infectious complications. Therefore, it seems to be a transient abnormal hematological finding and a self-limiting condition.

Malposition of a central venous catheter (CVC) in the accessory hemiazygos vein is an uncommon but potentially fatal complication; however, there is limited information regarding the preferred removal technique. We report a patient, a 57-year-old woman, who presented with overdose of her prescribed sedatives, who experienced this catheter complication after CVC insertion in the left internal jugular vein. The CVC was placed without resistance but routine postplacement chest X-ray showed abnormal coursing of the catheter close to the descending aorta. We used non-enhanced CT as an adjunct to safely identify the catheter position and assess for any bleeding during removal. CT images taken after retraction of the catheter tip by 10 cm showed no bleeding and we were able to remove the catheter safely. We recommend using CT as an adjunct to safely remove malpositioned catheters and reduce the risk of further complication.

RESUMO

Little is known as regards frailty in patients with functional tricuspid regurgitation (FTR). Thus, in this study, we aimed to investigate the prevalence, characteristics, and impact of frailty on patients with severe FTR.This prospective study included 110 consecutive patients with severe FTR who were assessed via transthoracic echocardiography at an outpatient clinic. Patients were dichotomized using short physical performance battery (SPPB). To better understand the whole picture of frailty in patients with FTR, other frailty scales were also assessed (frailty checklist, clinical frailty scale, gait speed, and Columbia frailty scale). The primary endpoint was the combination of all-cause mortality and heart failure hospitalization.According to each definition of frailty, 28%-46% were identified to be frail. Those with SPPB score of < 9 were older, had greater New York Heart Association (NYHA) functional classification, and had lower albumin level and estimated glomerular filtration rate compared with those with SPPB score of ≥ 9. They also have smaller tricuspid valve coaptation depth and worse right ventricular fractional area change (RV-FAC) than those with SPPB score of ≥ 9 despite having similar TR severity. The primary endpoint at 1 year was noted in 31% of patients. The SPPB score has excellent discriminatory performance for predicting the primary endpoint (area under the curve 0.82, 95% confidence interval [CI] 0.76-0.91) in receiver operating characteristic analysis and was independently associated with the primary endpoint after adjustment in multivariate analysis (adjusted hazard ratio 0.81, 95% CI, 0.73-0.90; P < 0.001).Frailty has been widely prevalent in the elderly patient population with FTR; in fact, it has been determined to be strong parameter for poor outcomes.
