RESUMO

In December 2019, in Wuhan, a new human infectious pathology was born, COVID-19, consisting above all in pneumoniae, induced by the coronavirus named SARS-CoV-2 because of the respiratory distress it caused (SARS for severe acute respiratory syndrome, and CoV for Coronavirus). A real health and planetary crisis has appeared, much more substantial than that linked to SARS-CoV-1 in 2002-2004 and to MERS-CoV (Middle East Respiratory Syndrome Coronavirus) in 2012. In addition to respiratory damage that can be dramatic, this pathology is complicated by the frequency of cardiovascular, renal and coagulation diseases. Health care systems have had to adapt urgently, in the absence of hindsight from the pathology, and without effective therapeutic weapons. Through this review of the literature, we detail our local practices for the overall management of patients hospitalized in Intensive care.


En décembre 2019, à Wuhan, une nouvelle pathologie infectieuse humaine est née, le COVID-19, consistant avant tout en une pneumonie, induite par le coronavirus nommé SARS-CoV-2 en lien avec l'intensité de la détresse respiratoire qu'il entraîne (SARS pour syndrome respiratoire aigu sévère, et CoV pour coronavirus). Une véritable crise sanitaire et planétaire est apparue, bien plus conséquente que celle liée au SARS-CoV-1 en 2002-2004 et au MERS-CoV (Middle East Respiratory Syndrome Coronavirus) en 2012. Outre une atteinte respiratoire pouvant être dramatique, cette pathologie est complexifiée par la fréquence des atteintes cardiovasculaires, rénales et de la coagulation. Les systèmes de soins de santé ont dû s'adapter urgemment, en l'absence de recul face à la pathologie, et sans armes thérapeutiques efficaces. Au travers de cette revue de la littérature, nous détaillons nos pratiques locales pour la prise en charge globale des patients hospitalisés aux Soins intensifs.

RESUMO

Infectious endocarditis is a rare pathology whose mortality is high and whose diagnosis is still difficult by the usual clinical, biological and ultrasound tools. We report the case of a patient, drug addict, suffering from an infectious endocarditis of the aortic valve at Streptococcus agalactiae. This germ is rarely at the origin of cardiac infection but it is responsible for quickly destructive lesion by its pathophysiological mechanisms. In this case, the infection unfortunately caused the death of the patient.


L'endocardite infectieuse est une pathologie rare dont la mortalité est élevée et dont le diagnostic reste encore difficile par les outils cliniques, biologiques et échographiques habituels. Nous rapportons le cas d'un patient, toxicomane, souffrant d'une endocardite infectieuse de la valve aortique à Streptococcus agalactiae. Ce germe est rarement à l'origine d'infection cardiaque, mais il est responsable de lésion rapidement destructrice par des mécanismes physiopathologiques qui lui sont propres. Dans ce cas particulier, cette infection a, malheureusement, occasionné le décès du patient.

RESUMO

The quadricuspid aortic valve is a rare congenital anomaly that could be silent for a long time. It is mostly isolated but it may also be associated with other malformations, especially anomalies of the coronary artery insertion. It can lead to aortic regurgitation with several degrees of severity, and it should be diagnosed as soon as possible to avoid left ventricular dysfunction and its morbi-mortality. We report the case of a 67-years-old female patient with recent discovery of moderate aortic regurgitation, which has beneficiated from surgical closure of an atrial septal defect in her childhood, and who has never been diagnosed with a quadricuspid aortic valve.


La quadricuspidie aortique est une anomalie congénitale rare dont l'évolution peut rester longtemps silencieuse. Elle est le plus souvent isolée, mais peut parfois être associée à d'autres malformations, dont les anomalies d'insertion des artères coronaires en premier lieu. Elle se complique, le plus souvent, d'insuffisance aortique dont la sévérité est variable, mais qu'il faut savoir diagnostiquer le plus tôt possible afin d'éviter les décompensations ventriculaires gauches et la morbi-mortalité qui en découle. Nous rapportons le cas d'une patiente de 67 ans, ayant bénéficié d'une fermeture chirurgicale de communication interauriculaire dans l'enfance, chez qui le diagnostic de quadricuspidie aortique n'a jamais été soulevé et qui présente une insuffisance aortique modérée de découverte récente.

RESUMO

The management of complex cardiovascular disease has changed considerably with the development of new care strategies. In cardiology, the «Heart Team¼ or literally «Equipe du cœur¼ occupies a prominent place in the latest European and American recommendations, particularly in the management of complex coronary or valvular diseases and in heart failure patients. The concept of «Heart Team¼ is based on the need for a multidisciplinary holistic approach based on evidence (respect of the recommendations of the scientific societies), the patient as a whole (comorbidities, preferences), risks and long-term benefits of the treatment selected and performed, as well as on the level of local expertise. It aims to determine the best management strategy for the patient, and perhaps to guarantee a better result (prognosis).


La gestion des maladies cardiovasculaires complexes a considérablement changé avec le développement de nouvelles stratégies de soins. En cardiologie, le « Heart Team ¼, littéralement « Equipe du cœur ¼, occupe une place prépondérante au sein des dernières recommandations européennes et américaines, notamment dans la prise en charge des maladies coronaires, des pathologies valvulaires et de l'insuffisance cardiaque. Le concept de « Heart Team ¼ se base sur la nécessité d'une approche multidisciplinaire holistique fondée sur l'évidence (respect des recommandations des sociétés savantes), le patient dans sa globalité (comorbidités, préférences), les risques et bénéfices à long terme du traitement choisi, ainsi que sur le niveau d'expertise locale. Il a pour but de déterminer la meilleure stratégie de prise en charge pour le patient et, peut-être ainsi, de lui garantir un meilleur résultat (pronostic).

RESUMO

In the last decades, interventional cardiology has received fast and wide implementation as an effective alternative treatment to surgery for several congenital and acquired diseases. Imaging provides solutions for most clinical needs, from diagnosis to prognosis and risk stratification, as well as anatomical and functional assessment. In this article, we present recent innovations in medical imaging for structural heart disease and coronary artery disease, emphasizing the progress achieved in the field of multimodality imaging. Intra-procedural guidance can be facilitated by established multimodality cardiac imaging such as transesophageal 2D and 3D echocardiography and by novel techniques as echo-fluoroscopy overlay and 3D imaging fusion. Computed tomography and magnetic resonance imaging are particularly helpful for preprocedural morphology assessment and device sizing. Successful planning, guidance, and monitoring of interventions depend heavily on accurate imaging for both structural heart disease and complex coronary artery disease.


Au cours des dernières décennies, la cardiologie interventionnelle s'est rapidement développée, et est devenue une alternative efficace à la chirurgie pour le traitement de plusieurs maladies congénitales et acquises. L'imagerie apporte des solutions à la plupart des besoins cliniques, du diagnostic au pronostic et à la stratification du risque, en passant par l'évaluation anatomique et fonctionnelle. Dans cet article, nous présentons les dernières innovations en matière d'imagerie médicale pour les maladies cardiaques structurelles et des artères coronaires, en soulignant les progrès réalisés dans le domaine de l'imagerie multimodale. Le guidage intra-procédural peut être facilité par une imagerie cardiaque multi-modalité telle que l'échocardiographie transoesophagienne 2D et 3D, ainsi que par de nouvelles techniques telles que la superposition d'écho-fluoroscopie et la fusion par imagerie 3D. La tomographie par CT scanner et l'imagerie par résonance magnétique sont particulièrement utiles pour l'évaluation pré-procédure de la morphologie et le dimensionnement des prothèses. La réussite de la planification, des performances et du suivi des interventions dépend, en grande partie, d'une imagerie précise pour les maladies cardiaques structurelles et les maladies coronariennes complexes.

RESUMO

Alcohol septal ablation has become an attractive alternative to surgical myomectomy in symptomatic patients with obstructive hypertrophic cardiomyopathy. Its purpose is to achieve a therapeutic infarction in the sub-aortic territory responsible of the obstruction. It is indicated in symptomatic patients resistant to optimal medical treatment and having a left intraventricular gradient equal or higher than 50 mmHg, spontaneous or with exercise. The selection of candidates must be rigorous and the procedure must be performed in an experienced center, associating interventionalists and echocardiographists. Alcohol septal ablation is preferred in cases of favourable coronary anatomy, sub-aortic obstruction and absence of associated mitral valve defect. The septal alcohol technique is fast, effective and safe. The per-procedural contrast echocardiography helps identifying whether the myocardial segment is vascularized by the septal branch to be occluded. The benefits of alcohol septal ablation are comparable to those seen with surgical myectomy in terms of functional class, exercise capacity, and gradient regression. The morbidity and mortality observed in the short and mid terms are globally equivalent to that of the surgical intervention. The major complication is dominated by the occurrence of complete atrioventricular block requiring the implantation of a definitive pacemaker, a complication in sharp decline since the contrast ultrasound-guided technique has become widespread.


L'alcoolisation du septum par voie percutanée est devenue une alternative séduisante à l'intervention de myomectomie chirurgicale chez les patients symptomatiques porteurs d'une cardiomyopathie hypertrophique obstructive. Son but est de réaliser un infarctus thérapeutique dans le territoire septal basal responsable de l'obstruction. Elle est indiquée chez les patients symptomatiques, résistant au traitement médical optimal et présentant un gradient intraventriculaire gauche égal ou supérieur à 50 mmHg, spontané ou à l'effort. La sélection des candidats doit être rigoureuse et la procédure doit être confiée à un centre expérimenté, associant cardiologues interventionnels et échocardiographistes. L'alcoolisation septale est à privilégier en cas d'obstruction sous-aortique avec anatomie coronaire favorable et absence d'anomalie associée de l'appareil sous-valvulaire mitral. La technique d'alcoolisation septale est rapide, efficace et sûre. L'échocardiographie de contraste per-procédure permet aisément de repérer la branche septale à alcooliser. Les bénéfices de cette technique sont comparables à ceux observés avec la myectomie chirurgicale en termes de classe fonctionnelle, de capacité à l'effort et de régression du gradient. La morbi-mortalité observée, à court et moyen termes, est globalement équivalente à celle de l'intervention chirurgicale. La complication majeure est dominée par la survenue d'un bloc auriculo-ventriculaire complet nécessitant l'implantation d'un pacemaker définitif, complication en net recul depuis que la technique échoguidée s'est généralisée.

RESUMO

After aortic valve diseases, mitral valve diseases represent the most numerous indications of surgical or percutaneous valvular intervention. Surgical management is favoured in severe symptomatic mitral regurgitation. In case of high or prohibitive surgical risk, new techniques are developed to allow percutaneous, less invasive management. In these circumstances, MitraClip® allows the treatment of mitral regurgitation in case of adequate valve morphology. Percutaneous balloon valvuloplasty is currently the first-line treatment of mitral stenosis related to rheumatic disease when anatomical features are favourable. Alongside the Inoue technique, which remains the classical procedure, other approaches are available with encouraging results.


Après les valvulopathies aortiques, les valvulopathies mitrales représentent les plus nombreuses indications d'intervention valvulaire chirurgicale ou percutanée. Une prise en charge chirurgicale est privilégiée dans l'insuffisance mitrale sévère symptomatique. En cas de risque chirurgical élevé ou prohibitif, de nouvelles techniques se développent pour permettre une prise en charge percutanée, moins invasive. Dans ces circonstances, le MitraClip® permet de traiter des insuffisances mitrales pour lesquelles la morphologie valvulaire est adéquate. La sténose mitrale survenant en cas de maladie rhumatismale est actuellement traitée, en première intention, par valvuloplastie percutanée au ballonnet lorsque les caractéristiques anatomiques sont favorables. A côte de la technique d'Inoue, qui reste la procédure classique, d'autres approches sont disponibles avec des résultats encourageants.

RESUMO

Paravalvular leaks (PVL) are a serious complication after surgical or transcatheter aortic valve replacement. They are mostly small and unimportant. When they manifest clinically (1 to 5 % of PVL), they can become responsible for severe hemolytic anaemia or cause congestive heart failure. For years, surgical re-intervention has been considered the treatment of choice for symptomatic patients with PVL. However, surgical re-intervention is associated with a high risk of morbidity and mortality. Percutaneous PVL closure is a less invasive alternative to surgical re-intervention. The safety and feasibility of percutaneous PVL closure has been confirmed in several studies. In this article, we discuss the issue of PVL and their percutaneous management.


Les fuites paravalvulaires (FPV) sont les complications les plus fréquentes des prothèses valvulaires chirurgicales ou percutanées. Elles sont, la plupart du temps, petites et sans importance clinique. Lorsqu'elles se manifestent cliniquement (1 à 5 % des FVP), elles peuvent devenir responsables d'une anémie hémolytique sévère ou être la cause d'une insuffisance cardiaque congestive. Pendant des années, la réintervention chirurgicale a été considérée comme le traitement de choix pour les patients symptomatiques atteints de FPV. Cependant, la reprise chirurgicale est associée à un risque élevé de morbidité et de mortalité. La fermeture percutanée des FPV est une alternative moins invasive à la réintervention chirurgicale. La sécurité et la faisabilité de la fermeture percutanée des FPV ont été confirmées dans plusieurs études. Dans cet article, nous discutons de la problématique des FPV et de leur prise en charge par voir percutanée.

RESUMO

Infective endocarditis is a rare disease that can lead to some diagnostic wandering because of its often nonspecific and polymorphic clinical manifestations. This latency is at the origin of severe cardiac and extra-cardiac complications, yet highly fatal. The clinician should always bear in mind the differential diagnosis of a patient with fever of undetermined origin, with risk factors for valve infection such as foreign material, and history recent invasive procedures (including dental procedures) or recent hospitalization. The current medical tools make it possible to highlight the infection and its complications in a fast and complete manner, so as not to delay the patient's management, particularly with the introduction of urgent empirical antibiotherapy.


L'endocardite infectieuse est une maladie rare pouvant entraîner une certaine errance diagnostique au vu de ses manifestations cliniques souvent aspécifiques et polymorphes. Cette latence est à l'origine de complications cardiaques et extra-cardiaques potentiellement mortelles. Le clinicien doit toujours avoir à l'esprit ce diagnostic différentiel face à un patient avec une fièvre d'origine indéterminée, et qui présente des facteurs de risque d'infection valvulaire tels qu'un matériel étranger, des antécédents récents de gestes invasifs (entre autres dentaires) ou d'hospitalisation récente. Les outils médicaux actuels permettent de mettre en évidence l'infection et ses complications de façon rapide et complète, afin de ne pas retarder la prise en charge du patient avec, notamment, l'instauration urgente d'une antibiothérapie empirique.

RESUMO

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) has been introduced into clinical practice by Miccoli in the late 1990s (Miccoli et al., Am J Surg 181(6):567-570, 2001) and it has become a widespread technique used and welcomed worldwide. In this paper, we present our experience of the last 2 years; we also describe tips and techniques derived from over 460 cases performed in the last 10 years by the same surgical team with the same single operator. METHODS: In the last 10 years, we did about 460 MIVAT procedures. In the last 2 years, we performed MIVAT on 156 consecutive patients at Sant'Andrea University Hospital of Rome "Sapienza" University. of 156 cases performed, we were able to monitor the follow-up in 110 patients. RESULTS: On 110 cases, the mean surgical time was 74 ± 7.2 min. In our data, we reported: transitory hypoparathyroidism 11 (10%), definitive hypoparathyroidism 4 (3.60%) (this value is inclusive of patients treated with central neck dissection. The value referred only to MIVAT is 1.05%), 2 (1.81%) transitory monolateral nerve palsy, 16 (14.50%) transitory, and 1 (0.9%) definitive nerve palsy. 4 (3.60%) cases of transitory dysphagia and 0 (0%) cases of definitive dysphagia (Table 4). We also had 1 (0.9%) case of surgical scar infection, 0 (0%) postoperative bleeding, and 2 (1.81%) cases of subcutaneous surgical adhesion. Cosmetic results were: 0 (0%) insufficient, 0 (0%) sufficient, 6 (6.30%) passable, 17 (15.50%) good. and 86 (78.20%) excellent. Conversion rate 0 (0%). CONCLUSION: MIVAT is a good and safe technique, with similar short-term outcomes and similar costs compared to traditional total thyroidectomy. We hope that the tips and techniques reported in this paper as well as the advices in the use of instruments in MIVAT and open surgery will be useful to improve the skills of young surgeons and make thyroid surgery less invasive.

RESUMO

Until recently, the recommendations of infective endocarditis were based on expert opinions, due to its low incidence and the absence of controlled trials. The update in 2015 of the new guidelines of the European Society of Cardiology (compared with 2009) relates to the publication of a randomised study on the surgical treatment, the innovations in imaging procedures (especially functional imaging in nuclear medicine) and the new concept of «Team Endocarditis¼ (multidisciplinary approach). Their aim is to remind the limitations of antibiotic prophylaxis and to insist on hospital hygiene measures. Future challenges will be to obtain a better understanding of the mechanisms associated with the contamination of the valve and to optimize the adaptation of the current epidemiological prophylaxis. In this first part, we will describe the preventive and diagnostic approaches of infective endocarditis.


Jusqu'à ce jour, les recommandations concernant le traitement de l'endocardite infectieuse étaient essentiellement basées sur l'opinion d'experts, à cause de sa faible incidence et de l'absence d'essais contrôlés. La mise à jour, en 2015, des recommandations de la Société Européenne de Cardiologie de 2009, est justifiée par la publication d'une première étude randomisée sur le traitement chirurgical, par les innovations concernant les procédures d'imagerie (particulièrement l'imagerie fonctionnelle en médecine nucléaire) et par le nouveau concept d'«Endocarditis Team¼ (approche multidisciplinaire). Ces directives européennes ont le mérite de rappeler les limitations de l'antibioprophylaxie et d'insister sur les mesures préventives à prodiguer. Les défis futurs seront de mieux comprendre les mécanismes associés à la contamination de l'endocarde valvulaire et de mieux adapter la prophylaxie à l'évolution épidémiologique. Dans cette première partie, nous décrivons la prophylaxie et les moyens diagnostiques de l'endocardite infectieuse.

RESUMO

We report the history of a 20-year-old woman admitted for thrombosis of the sus-hepatic veins and of the inferior vena cava (IVC) with extension of the thrombus into the right atrium. The etiological research was negative and a diagnosis of idiopathic Budd-Chiari syndrome was retained. In view of the absence of vein repermeabilisation under adequate anticoagulant therapy, a venous thrombectomiy was performed under cardiopulmonary bypass, which improved the hepatic venous drainage. Budd-Chiari syndrome is a very serious disorder. Its treatment implies a step by step procedure. An effective anticoagulation must first be established. The complications of portal hypertension then require attention. For a symptomatic patient, one should assess the possibility of restoring the venous permeability, improving the hepatic drainage and decompressing the liver by radiological interventional or surgical procedures. Finally, an hepatic transplantation should be considered in case of treatment ineffectiveness, of fulminant hepatic failure, or of an evolution towards cirrhosis.

RESUMO

Even though cardiac disorders were described in alcoholic cirrhosis more than fifty years ago, cirrhotic cardiomyopathy was not defined until the end of the eighties. The term is used to describe all the cardiac structural and functional abnormalities observed in cirrhotic patients without any underlying cardiac disease. This cardiomyopathy is characterized by impaired systolic function, often unmasked during stress, diastolic dysfunction, and electrophysiological abnormalities. It can be detected by the electrocardiogram, transthoracic echocardiography and measurements of cardiac biomarkers (BNP). The pathophysiological mechanisms underlying this disease are complex: anomalies of adrenergic transduction pathways, alterations of myocyte membrane fluidity, fibrosis, cardiac hypertrophy, hormonal disturbances, and various ion channels derangements. To date, there is no specific treatment. Liver transplantation may be curative. The possibility of such a condition must be taken into account, when a TIPS or a liver transplantation are considered.

RESUMO

BACKGROUND: The purpose of this study was to compare the microbiota around natural teeth and dental implants with different restorative platforms. Attention was focused on whether the microbiological environment could change according to the implant platform used i.e. traditional or Platform Switching implants. As the latter show less signs of bone resorption, a correlation with the presence of certain periodontal bacteria was suggested. METHODS: Seven partially edentulous patients with dental implants, either traditional or Platform Switching, were included in this study. All the implants were in function at least for 1 year. Gingival crevicular fluid samples were obtained before any periodontal probing from natural teeth and different implant platforms and assayed using DNA extraction and PCR sequences in order to determine quality and quantity of microbiota. Statistical analysis included chi square test were used to establish differences in the microbiological distribution between the two implant platforms. RESULTS: There were not statistical differences neither regarding the distribution of microbiota around natural teeth and implants nor between the two implant platforms. The presence of B.forsythus was revealed in the majority of the samples (from 90 to 100 percent) while A.actinomycetemcomitans was rarely found (from 0 o 25 percent). As for the other periodontal microbiota, their presence or absence showed a variation according to different sites or patients, without a predictable pattern. CONCLUSIONS: It was not possible to find a link between the colonization of certain types of bacteria and the reduction of bone loss which occurs around Platform Switching implants. Therefore the preservation of bone crest is only due to biomechanical aspects, which are related to the reposition of the implant-abutment interface away from the outer edge of the implant platform and from the bone.
