Management of infective endocarditis and multidisciplinary approach.

INTRODUCTION: The morbi-mortality related to infective endocarditis (IE) remains high as the epidemiology has changed over the last years: ageing of patients, comorbidity and healthcare-associated infections. To optimize IE management, a weekly endocarditis multidisciplinary meeting (EMM) was set up at our facility. We present the activity report of the EMM. PATIENTS AND METHODS: All patients hospitalized for IE who were presented at the weekly EMM between January 2013 and June 2017 were prospectively included. The main objective was to assess the impact of the EMM on the management of community-acquired IE and healthcare-associated IE by analyzing in-hospital case fatality. RESULTS: Of the 1139 cases reported during the EMM for suspicion of IE, 493 (86% were definite cases) were selected for the study: 262 patients had community-acquired IE and 231 had healthcare-associated IE; 43% of IEs involved a valvular prosthesis. Following the EMM, infections were documented in 92% of cases: staphylococci in 45% of healthcare-associated IEs and streptococci in 44% of community-acquired IE cases. A septic embolism was diagnosed in 57% of cases. Finally, 49% of patients underwent surgery. The in-hospital case fatality was 12% with no significant difference between community-acquired IEs and healthcare-associated IEs. Case fatality was also significantly higher in elderly patients, in the absence of surgical treatment, initial heart failure, or Staphylococcus aureus IE. CONCLUSION: The weekly EMM allows our facility to follow the European Society of Cardiology guidelines and to adapt the management of each patient to improve IE prognosis.

Impella 5.0 microaxial pump as a right ventricular assist device after surgical treatment of posterior post-infarction ventricular septal defect.

The Impella Recover LP 5.0 is an aortic transvalvular microaxial pump designed to unload the left ventricle and to ensure a systemic flow in severe left ventricular dysfunction. We propose a new suggestion for the Impella 5.0 as a temporary right ventricular assist device after the surgical treatment of a posterior post-infarction ventricular septal defect.

Complications arising after thoracic aortic surgery: a case report on an unusual spinal cord infarction. Physiopathological and clinical considerations.

Even though new prevention techniques have been developed and are being used during thoraco-abdominal aortic repairs, spinal cord infarction remains a severe and relatively frequent complication of aortic surgery. Infarctions in the territory of the anterior spinal artery are considered the most common. Different clinical pictures related to spinal cord transverse extension wounds are drawn up. In this paper, we present a case report of a subject having presented an isolated motor deficit of the lower limbs and a favorable prognosis, suggesting selective involvement of the anterior horns of the spinal cord subsequent to surgical repair of an aortic dissection. We wish to review the relevant anatomical, clinical and diagnostic characteristics along with current techniques of spinal cord ischemia prevention during and after surgery.

[Place of traditional CBP in bipulmonary transplantation]. / Place de la CEC traditionnelle en transplantation bipulmonaire.

Initially double-lung transplantation (DLT) was performed with airway anastomosis at the tracheal bifurcation requiring a cardiopulmonary bypass (CBP). Complications related to ischemia of the bronchi and trachea around the carina prompted adoption of sequential single lung implantations as the method of choice for DLT. In different studies, CPB was associated with an increase in postoperative morbidity but this was probably due to the selection of more severe patients. Moreover, important progress in the technology of CPB has occurred. Therefore, the systematic use of CPB during sequential lung transplantation might have some interest by limiting the occurrence of ventilation and perfusion injuries. This article discusses the potential beneficial effects of CPB during double-lung transplantation.

Assessing cardiovascular risk factors after coronary artery bypass surgery: value of an aggressive strategy including systematic follow-up.

INTRODUCTION: Coronary revascularization surgery is a palliative treatment modality which should not preclude efforts to treat atherosclerosis. AIM: To assess ongoing cardiovascular risk factors after coronary artery bypass surgery and develop a strategy to attenuate such factors. METHODS: 108 patients requiring a coronary artery bypass were included: 2 died soon after surgery and 6 were excluded for personal reasons. 100 patients were re-admitted into hospital 7 months after surgery for risk factor assessment. Eight months later, they were re-contacted by telephone (systematic follow-up) for a re-assessment. RESULTS: The population consisted of 77 men with an average age of 64+/-11 years. Prior to the operation, the known risk factors were: smoking 34%; HBP 61%; cholesterol 47%; diabetes 30%; obesity 25%. During their hospital stay six months after the procedure: 91% of the patients had at least one lipid metabolism abnormality. New-onset diabetes was diagnosed in 5%. Blood pressure was uncontrolled in 18% and 10% were still smoking. Patients tended to be putting on weight and 55% engaged in little or no physical activity. Systematic follow-up: lipid metabolism had normalized in 70% of the patients. Blood glucose levels were significantly lower. Blood pressure was uncontrolled in 9% and 4% were still smoking. Their weight had stabilized and 65% were engaging in moderate-to-strenuous physical activity. CONCLUSION: Inadequate attention is paid to risk factors after coronary artery bypass surgery. A short hospital stay including a cardiovascular evaluation and education about risk factors has a positive impact on the management of atherosclerosis in the medium term.

[Vascular biology of coronary bypass grafts. Literature review]. / Biologie vasculaire des greffons coronaires. Un état des lieux.

Myocardial revascularisation by coronary bypass surgery is the treatment of choice for patients with multivessel disease. The most commonly used grafts are the internal mammary artery and the saphenous vein. Although the use of internal mammery artery grafts gives excellent results, venous grafts, with time, are subject to atheroma which affects their patency. Improved physiopathological understanding of the natural history of grafts, especially the saphenous vein grafts, has opened the field for different operative strategies to try and reduce the incidence of coronary graft disease. This paper reviews the literature concerning the biology of coronary grafts used for myocardial revascularisation and the current and future therapeutic implications of this data.
