Native arteriovenous fistulae (AVF) are the best options for chronic hemodialysis (HD) access. In elderly, diabetics or patients with late initiation of HD we need to adapt surgical procedures, taking advantage of any opportunity to overcame shortcomings and create a native dialysis access. The case that we present has the particularity of a deep cephalic vein that required superficialization of the acquired brachiocephalic AVF in a normal weight patient (body mass index = 18.6 kg/m2). At the intervention for fistula formation, the poor nutritional status (moderate malnutrition - albuminemia = 2.9 g/dL) and the thin walls of the vein obliged us to perform the two-step procedure: first the creation, then the transposition of the fistula. The presence of two collateral veins imposed a classical intervention that allowed the ligature of these tributary vessels for a better fistula maturation. There were no injuries of the vessels or inflammatory / infectious complications, no impediment for cannulation due to overlapping scar after superficialization. In the dialysis vascular access planning algorithm we must consider all the conditions of the patient, anatomical particularities and the best way to ensure the longevity of the AVF. All the techniques available must be considered as options. [ABSTRACT FROM AUTHOR]

The liner is one of the most important part of the lower limb protheses, whose role is to maintain the contact between the residual limb and the socket. Taking into account the residual limb has a variable volume, we have analysed the closed-cell prototype of the liner made of silicon rubber RTV-2. The mechanical properties of this material could provide the requirements imposed for the lower limb prostheses. Meantime it is innocuous for the human body, especially for skin contact and could be used for medical devices manufacturing.

Objectives: This observational study aimed to evaluate Association pour l'Etude et la Prévention de l'Endocardite Infectieuse (AEPEI) surgery score predictive performance in comparison to general (EuroSCORE I, II) and specific (De Feo, PALSUSE) surgical risk scores for infective endocarditis (IE)., Methods: The study included patients who underwent surgery for IE during the acute phase at Bichat University Hospital (Paris, France) between 1 January 2006 and 31 December 2016 and at Nancy University Hospital (Nancy, France) between 1 January 2009 and 31 December 2019. Patients with IE complicating percutaneous aortic valve implantations or implantable intra-cardiac devices were excluded. Discrimination and calibration were assessed using receiver operating characteristic curve analysis, calibration curves and the Hosmer-Lemeshow test., Results: In-hospital mortality rates were 18% at Bichat and 16% at Nancy. Discrimination was high for all risk scores at Bichat (area under the receiver operating characteristic curve = 0.77 for EuroSCORE I, 0.78 for EuroSCORE II, 0.76 for De Feo score, 0.72 for PALSUSE and 0.73 for AEPEI with 95% confidence interval ranging from 0.67 to 0.83), but lower at Nancy (0.56 for EuroSCORE I, 0.65 for EuroSCORE II, 0.63 for De Feo score, 0.67 for PALSUSE and 0.66 for AEPEI score with 95% confidence interval ranging from 0.47 to 0.75). With Brier score, all scores were adequately calibrated in both populations between 0.129 (De Feo) and 0.135 (PALSUSE) for Bichat and between 0.128 (De Feo) and 0.135 (EuroSCORE I) for Nancy. With the Hosmer-Lemeshow test, the AEPEI score exhibited the best calibration (observed/predicted ratio 1.058 in Bichat, 1.087 in Nancy)., Conclusions: This surgical score external validation in 2 large independent populations demonstrated that the AEPEI surgical score had the best predictive performance compared to other prognosis scores. It could be helpful in clinical practice to assist the endocarditis team in decision-making., (© The Author(s) 2024.

Objective: The aim of our study was to evaluate the outcome of patients with severe aortic stenosis presenting with acute decompensated heart failure (ADHF) and planned for transcatheter aortic valve implantation (TAVI) and to study the variables influencing their prognosis., Methods: Our retrospective study included 801 patients planned for TAVI in our center. Seven hundred and fifty-six underwent TAVI and were categorized according to ADHF as the initial clinical presentation into two groups: ADHF group (n = 261) and no-ADHF group (n = 495). Pre as well as periprocedural outcomes and 1 year mortality were analyzed., Results: Among the patients planned for the TAVI procedure, 45 patients remained untreated: 35 patients died while waiting to undergo TAVI which represented 20% of all deaths in our study, ADHF was observed in 23 of 45 (51%) these untreated patients. The 1-year all-cause mortality rate was significantly higher in the ADHF group versus the no-ADHF group (27% vs. 15%, p < .0001). In multivariate analysis, male gender (odds ratio [OR] =2.5, 95% confidence interval [CI]: 1.37-4.57, p = .03), body mass index <25 kg/m 2 (OR = 2.76, 95% CI: 1.51-5.04, p = .0009), and logistic EuroSCORE II ≥20% (OR = 3.04, 95% CI: 1.56-5.94, p = .001) were associated with a higher 1-year mortality in the ADHF group., Conclusion: The patients eligible for TAVI presenting with ADHF were associated with a higher mortality for both: while on the waiting list for TAVI as well as at 1-year follow-up and thus asking for clearer criteria to prioritize action in this high-risk TAVI patients., (© 2020 Wiley Periodicals, Inc.)

Antibiotic treatment of infective endocarditis is part of a multidisciplinary patient management that should be conducted within an "Endocarditis team". Initial antibiotic treatment of infective endocarditis should be parenteral and comply with current international guidelines. A switch to an oral antibiotic regimen may be considered after 2weeks of successful parenteral antibiotic treatment. Aminoglycosides should no longer be used for the initial treatment of native valve Staphylococcus aureus endocarditis. Valve surgery is required in almost half of the patients., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Objectives: Transcatheter aortic valve implantation is a well-recognized treatment option for high-risk patients with aortic stenosis. The femoral approach is possible in 80% of cases and remains the access of choice. When this approach is not feasible, other alternative routes have been proposed such as transapical, transaortic and subclavian. Transcarotid aortic valve implantation has been proposed as another direct vascular access. Its use is relatively new and still under evaluation., Methods: We successfully performed transcarotid aortic valve implantation in 145 consecutive patients through the left or right carotid artery in 3 different French sites over a 2-year period. Data were prospectively entered in the French transcatheter aortic valve implantation database., Results: The mean age was 79.8 ± 8.7 years, with a mean logistic EuroSCORE of 20.7 ± 12.6%. The procedure was successful in all patients, and no conversion was necessary. Thirty-day survival was 93.7%, 8 (5.5%) patients presented either minor or major strokes and 1 patient had a localized asymptomatic carotid dissection. All patients were immediately extubated, and none presented respiratory complications., Conclusions: Transcarotid aortic valve implantation is a safe alternative to transfemoral transcatheter aortic valve implantation, with direct access to the aortic valve, which can be performed with limited incision., (© The Author 2017.

Background: Patients with non-ST elevation acute coronary syndrome complicated by left ventricular dysfunction (LVEF) are a poor prognosis group. The aim of our study was to assess the short and long term LEVF prognostic value in a cohort of NSTE-ACS patients undergoing surgical revascularization., Methods: We performed elective and isolated CABG on a cohort of 206 consecutive patients with LVEF≤0.40 complicating acute coronary syndrome. The case cohort was compared with a cohort of controls (LVEF>0.40) randomly selected (2:1) among patients who underwent the procedure during this period., Results: The Kaplan-Meier 5-year estimated survival rates for patients in the low and normal LVEF groups were 70.8% (95% confidence interval CI: 64.2-77.4) and 81.7% (95%CI: 77.8-85.6), respectively. A low LVEF was associated with both a higher all-cause (HR [95%CI] = 1.84[1.18-2.86]) and a higher cardiovascular mortality (HR = 2.07 [1.27-3.38]) during the first 12 months of follow-up. After adjustment for potential confounders, a low LVEF remained associated with a higher cardiovascular mortality only (1.87[1.03-3.38]) during the first 12 months of follow-up. After 12 months of follow-up, a low LVEF was no more associated with all-cause, nor cardiovascular mortality., Conclusion: Patients with low LVEF might require more intensive care than patients with normal LVEF during the year after the surgical procedure, but once the first postoperative year over, the initial low LVEF was no more associated with long term mortality., Competing Interests: The authors have declared that no competing interests exist.

Transcatheter aortic valve implantation is a well-recognized treatment option for high-risk patients with aortic stenosis. The femoral approach is possible in 80% of cases. Initially, only the transcarotid and subclavian approaches were performed as alternative routes. Both approaches have advantages and disadvantages. The carotid approach is a new approach that offers direct vascular access to the aortic valve. The technique of access is very simple and well known to all cardiovascular surgeons, and the morbidity is minimal. It avoids a thoracotomy with all its complications. We present here our technique and results of our initial experience., (© The Author 2016. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

Background: There is controversy concerning the performance of small aortic prostheses (size < 21). These have been associated with morbidity and mortality after aortic valve replacement (AVR) due to their increased gradient. Sutureless technology is now available but the performance of the smallest of these prostheses needs to be assessed., Methods: The registries of 4 European centers, including 276 consecutive patients (mean age 79.7 ± 5.2 years, 69.9% females), were reviewed in order to compare data on the smallest model of the Sorin-Perceval sutureless prosthesis (Sorin Group, Saluggia, Italy) compared with larger models. The small valve ("S" size) was inserted (S group) in 47 patients, while 229 patients had a larger one (labeled "M" and "L" by manufacturer, herein L group). Except for body surface area (1.60 ± 0.16 vs 1.78 ± 0.19 m(2), p < 0.001), there were no other relevant preoperative differences. The European system for cardiac operative risk evaluation log was 11.4 ± 6.1 versus 12.6 ± 9.6 (p = 0.28)., Results: Median sternotomy was the most frequent approach (S group 87.2% vs L group 79.5%, p = 0.31). The associated procedures were similar for both groups (31.9% vs 34.5%, p = 0.87). For isolated AVR, cardiopulmonary bypass and cross-clamp times were, respectively, 49.1 ± 16.0 and 30.7 ± 9.2 minutes (S group) versus 52.6 ± 23.1 and 32.3 ± 13.6 minutes (L group) (p = 0.33 and 0.45). Hospital mortality was nil (S group) versus 2.6% (L group) (p = 0.62). At discharge, the peak-pressure-gradients were 22.7 ± 7.9 and 20.9 ± 8.4 mm Hg (p = 0.24) while indexed effective orifice areas were 0.84 ± 0.16 and 0.86 ± 0.25 cm(2)/m(2) (p = 0.76). At follow-up (1.5 ± 1.3 years), echo data and survival did not differ (p = 0.17)., Conclusions: This multicenter study confirms the safety, efficacy, and ease of insertion of Perceval valves in elderly patients with small annulus. The performance of the smaller prosthesis was satisfying and prosthesis size did not affect patient outcome., (Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Catheter ablation is a well-established therapeutic option for management of recurrent ventricular tachycardia in patients with ischemic/non-ischemic heart disease and procedural complications include a mortality rate of up to 3% and a risk of major complications up to 10%. Cardiac perforation following a catheter ablation is rare but serious complication and occurs in 1% of ventricular ablation procedures. The appropriate surgical repair may be challenging and need cardiopulmonary bypass support according to the location of the lesion and the hemodynamic status of the patient. We report the case of a free wall right ventricular perforation of the interventricular groove with cardiac tamponade following catheter ablation for recurrent ventricular tachycardia. Due to the proximity of the left anterior descending artery and the extreme fragility of tissues, the patient was treated successfully by a sutureless patch technique using a fibrin tissue-adhesive collagen fleece (TachoSil®). This technique is a safe and effective surgical option to repair a ventricular perforation especially when the ventricular tissues are fragile. It is simple and enable to realize surgical repair also if the localization of tear is difficult to access and without the need for cardiopulmonary bypass support if hemodynamic conditions are stable.

Background: Arterial complications among drug addicts are rare. Their appearance can engage the vital prognosis of the patient and present a major risk of amputation. The injection of products with high cellular toxicity induces septic necrosis of the arterial wall and adjacent tissues. It is frequently responsible for acute hemorrhage. The data in the literature concerning surgical treatment are discussed. The goal of our study was to analyze the immediate and midterm results of the surgical management of these arterial lesions., Methods: Between January 2005 and April 2012, 31 drug addicts (4 women; 31.4 ± 7.2 years) presenting with 33 arterial lesions were treated. They presented with a humeral (n = 15), femoral (n = 13), or axillar (n = 3) false aneurysm. Two patients had an arterial thrombosis. The clinical manifestations were an acute hemorrhage (n = 16), a septic syndrome (n = 7), a pulsatile mass (n = 6), and an acute ischemia (n = 4). In situ revascularization was carried out in 20 cases, in 15 patients with a bypass (9 venous and 6 prosthetic), in 2 with a venous patch, in 2 by direct suture, and in 1 by transposition of the superficial femoral artery in the deep femoral artery. Extra-anatomic bypass revascularization was performed in 6 cases (4 venous and 2 prosthetic). The other techniques used were ligature (n = 5) and medical care (n = 2). Two patients had an additional procedure with a musculocutaneous epigastric pedicled flap in order to fill the loss of substance., Results: The early rate of reinterventions was 38.7% at 30 days (12 patients), because of a suture line hemorrhage related to sepsis (n = 6), a bypass thrombosis (n = 5), and of acute ischemia after a arterial ligature. These complications occurred mainly on extremities, having had an anatomic revascularization (n = 9). Six extra-anatomic revascularizations had to be performed in second intention. The average follow-up was 8.6 months (range: 1-73.5 months), and 15 patients were lost to follow-up at 6 months. The patients were followed by duplex ultrasonography and/or angioscanner. Primary and secondary actuarial patencies at 1, 3, and 6 months were 61%, 46%, 46%, and 91%, 81%, and 71%, respectively. The rate of salvage of extremities was 100%., Conclusion: Our study reveals the difficulty of the management of these arterial lesions. The local and general septic process is primarily responsible for early complications. Arterial restoration with extra-anatomic bypass makes it possible to be distant from the infection. This technique can be associated with a covering flap., (Copyright © 2014 Elsevier Inc. All rights reserved.)

We report the case of a 66-year-old male with increasing angina occurring after two previous coronary artery surgery procedures. The second operation had been complicated by severe mediastinitis necessitating surgical drainage, and sternal stabilization. Angiography revealed an occlusion of the LAD bypass with a patent LAD associated with a stenotic circumflex coronary artery. The ascending aorta was severely calcified. An off-pump axillo-LAD coronary artery bypass was safely performed in conjunction with stenting of the circumflex artery. This approach dramatically simplified the procedure and reduced the operative risk. At the 52-month follow-up, the patient is free of any angina symptoms., (© 2013 Wiley Periodicals, Inc.)

Objectives: We sought to determine the incidence of femoral pseudoaneurysm (FPA) following cardiac catheterization, identify the risk factors for FPA and factors influencing therapeutic strategy., Methods: 11,992 consecutive patients who underwent cardiac catheterization via femoral artery were studied over a period of four years in one University Hospital. Our prospective case control group analysis registered patients who developed FPA after the procedure. Patient-related factors, procedure related factors and peri-procedure treatment were compared between the two groups., Results: 76 FPA were diagnosed over the study period accounting for a global incidence of 0.6% procedures. By univariate analysis, interventional procedure (p<0.01), rhythmologic procedure (p=0.03), sheath>or=6F (p=0.04) and left groin puncture (p<0.001) were FPA risk factors. By multivariate analysis, interventional procedure (adjusted odds ratio [OR]=1.99; 95% confidence interval [CI]1.14-3.44 p=0.01) and left groin puncture (OR=4.65; 95% CI, 1.78-12.1 p=0.001) are independent predictive factors of FPA. FPA thrombosis was obtained by ultrasound guided compression (UGC) in 71% of the cases. By univariate analysis, PFA diameter larger than 4 cm (p<0.001), the use of anticoagulation (p<0.01) or GPIIbIIIa inhibitors (p=0.001) and UGC under anticoagulation (p=0.01) are predictive factors of need for FPA surgical repair. By multivariate analysis, FPA diameter>4 cm and use of GPIIbIIIa inhibitors are independent predictive factors of FPA's surgical treatment. Superficial femoral puncture was predictive of successful UGC both by uni and multivariate analysis., Conclusions: Our study shows that FPA occurrence is mainly due to by procedure-related factors. FPA size, level of puncture and the use of GPIIbIIIa inhibitors are independent predictive factors of need for surgical therapy., (Copyright (c) 2008 Elsevier Ireland Ltd. All rights reserved.)

Infected aneurysms caused by Yersinia are very uncommon and are principally due to Yersinia enterocolitica. We describe the first case of an infected aneurysm caused by Yersinia pseudotuberculosis in an elderly patient with a history of atherosclerotic cardiovascular disease.

Therapeutic Options: Prognosis of advanced heart failure is ominous since survival rate is less than 65% one year after an acute and severe cardiac episode. Medical therapy has proven to be efficient in reducing fatal complications and in delaying critical evolution. Depending on the etiology and the myocardial status, new surgical approaches can also be proposed for repair or substitution. SURGICAL REPAIR: The beneficial effect of myocardial revascularization on severe ischemic cardiomyopathy, the relevance of mitral valve repair in dilated cardiomyopathy, and the advantage of ventricular remodeling in patients with major ventricular dyskinesia has been clearly demonstrated. All these surgical techniques improve ventricular function and enhance survival rate by about 70% after three years. SUBSTITUTION PROCEDURES: The best therapeutic option to recover heart function for normal life and reduced mortality remains, when possible, cardiac transplantation. Ventricular cardiac assist devices are planned as a temporary option to bridge the waiting period to transplantation or for myocardial recovery but can also be proposed as a chronic implantation in an outpatient care scheme. Cardiomyoplasty for therapeutic management of advanced cardiac failure is still a controversial surgical approach. Other clinical strategies such as transmyocardial laser revascularization, myocardial angiogenesis and myocardial cell therapy are being investigated or developed. ADAPTED TREATMENT: Optimal management of each patient with advanced heart failure requires an adequate treatment selected among a wide range of medical and/or surgical strategies.

The authors report 3 cases of major graft dysfunction after cardiac transplantation which recovered completely with biventricular mechanical assistance in 4 to 8 days. All three cases were primary biventricular graft failures in patients with normal preoperative pulmonary resistances. These early dysfunctions (with no signs of myocardial infarction on electro- or echocardiography and in the absence of abnormal increased peri-operative enzyme levels) associated with total functional recovery conforming to the definition of the phenomenon of myocardial stunning. These results argue in favour of aggressive management of primary graft dysfunction.
