[Oedematous polyarthritis and myopericarditis as presenting features of periarteritis nodosa]. / Polyarthrite oedémateuse et myopéricardite révélatrices d'une périartérite noueuse.

Remitting symmetrical seronegative synovitis with pitting edema (RS3PE) syndrome is a rare type of seronegative polyarthritis occurring in the elderly. It can be associated to various diseases. We report a case of RS3PE syndrome associated with myopericarditis, leading to the diagnosis of polyarteritis nodosa in a 71-year-old patient admitted to the hospital for a febrile acute polyarthritis with pitting edema of the hands associated with a marked inflammatory syndrome. On second day of hospitalization, a sustained chest pain led to the diagnosis of myopericarditis. Muscular biopsy showed necrotizing vasculitis, characteristic of polyarteritis nodosa. The coexistence of RS3PE and myopericarditis has never been described in the literature. Its association with polyarteritis nodosa is also very rare and only one case has been previously reported.

[Right ventricular failure as the presenting manifestation of a carcinoid syndrome]. / Atteinte cardiaque droite révélatrice d'un syndrome carcinoïde.

We report a 75-year-old woman with a severe and symptomatic valvular tricuspid dysfunction, revealing a carcinoid syndrome, confirmed by an octreotid scan and liver biopsy. Carcinoid heart disease is a common complication of carcinoid syndrome associated with poor prognosis. Despite new pharmacological treatment, valve replacement surgery is the only curative treatment. Early diagnosis and multidisciplinary management could improve prognosis and quality of life of these patients.

[Myocarditis caused by Trichinella spiralis: a case report]. / Myocardite à Trichinella spiralis: à propos d'un cas.

Trichinellosis is a cosmopolitan nematodosis which is rare in the developed countries. Myocarditis represents the most frequent form of cardiac complications, sometimes lethal. The authors report the observation of a 36-years-old patient admitted for trichinellosis, who presented asymptomatic electrocardiographic modifications and a rise in the troponine I. The magnetic resonance imaging (MRI) after gadolinium injection, highlighted an underepicardic late raising rendering the diagnosis of myocarditis highly probable. The paraclinic anomalies were corrected gradually under antiparasitarian treatment. Besides the EKG, the MRI is a non-invasive and repetitive method allowing as well the positive diagnosis as the follow-up of those patients.

[About two cases of trichinellosis caused by Trichinella britovi]. / A propos de deux cas de trichinellose à Trichinella britovi.

Trichinellosis is a cosmopolitan zoonosis due to a nematode threadworm, Trichinella, essentially Trichinella spiralis. Human cases mostly appeared sporadically, sometimes endemically, related with consumption of larva stinking meat. We report two cases of trichinellosis, including a myocarditis, caused by Trichinella britovi after consumption of frozen wild boar meat.

[Initial management of ST-elevation myocardial infarction in 2014: From guidelines to practices, survey of 176 French interventional cardiologists]. / Prise en charge initiale du syndrome coronaire aigu avec sus-décalage du segment ST en 2014 : des recommandations à la pratique, enquête auprès de 176 cardiologues interventionnels français.

BACKGROUND: Real life management of myocardial infarction has not recently been evaluated in France. AIMS: To describe ST-elevation myocardial infarction management in France in 2014 and to compare it with current guidelines. METHODS: A multicentre study was performed. An e-mail questionnaire was sent to French interventional cardiologists. Demographic data of interventional cardiologists, procedural aspects of percutaneous coronary intervention, antithrombotic treatments and patient rehabilitation have been investigated. RESULTS: One hundred and seventy-six answers were analysed. Most of centres realized more than 600 annual angioplasties. An average of 209 myocardial infarctions were managed per centre in 2014, more often in academic than in general or private centres (respectively 51, 32 and 17% of infarctions). Anti-GPIIbIIIa (34% of the cases) and thromboaspiration were not systematic but depend on patient's characteristics, according to guidelines. Radial access was favoured in 85% of the cases and increased for the last decade. Drug eluting stents were used in 62% of cases. Unfractionated heparin and enoxaparine accounted for more than 80% of anticoagulants treatments. Overall, use of clopidogrel was as high as that of prasugrel or ticagrelor although clopidogrel is recommended in second-line. Cardiovascular rehabilitation was proposed to more than 50% of patients. CONCLUSION: In spite of heterogeneity of ST-elevation myocardial infarction management in 2014, real-life practices generally comply with current guidelines.

[Infective endocarditis: Clinical features and prognosis between 2004 and 2014 in a non-teaching hospital]. / Endocardite infectieuse : caractéristiques cliniques et pronostic entre 2004 et 2014 dans un hôpital non universitaire.

AIMS: Despite diagnostic and therapeutic advances, infective endocarditis (IE) remains a severe disease. The aim of the study was to describe clinical features and prognosis of patients with IE in a non-teaching hospital and compare them with current data and a similar study conducted 10 years earlier in the same center. METHODS: We performed a single institution retrospective study including all patients with Duke-Li definite IE between 2004 and 2014. RESULTS: Ninety-four patients were included. Results are consistent with current French and international data, including in-hospital death rate of 16%. In accordance with literature, we report on an increase in Staphylococcus and health care-associated IE and endocarditis on pacemaker leads, but without significant difference compared to our previous study. In univariate analyses, renal failure, age over 77 years and Staphylococcus aureus IE were associated with in-hospital mortality. In multivariate analyses, predictors of in-hospital death were renal failure and lack of surgery. There was a non-significant trend of excess mortality in Staphylococcus endocarditis and in patients with heart failure. CONCLUSION: IE remains a severe disease and S. aureus is more often involved. IE seems to be safely managed in a peripheral hospital provided that there is a partnership with a reference hospital.

[Osborn J wave. A new "channel pathology"? A case report]. / Onde J d'Osborn. A propos d'une observation, une nouvelle Canalopathie"?

We report, at the time of a hypothermia major, the observation of an anomaly of the repolarisation on the electrocardiogram of surface, called "J wave", and described in an exhaustive way by Osborn, which attached its name there. It corresponds to the picking of the terminal section of the QRS, with heightening in dome, the J point is then elevated compared to the base line. It can be also seen among patients normothermic in physiological or pathological circumstances. Its physiopathology from now on is understood better, the J wave is the result of the difference of potential action between the epicarde and endocarde during phases 1 and 2 of the ventricular repolarisation. This gradient is related to the Ito current, also accused in the "channel pathologies", of which Brugada syndrome.

[Acute coronary syndrome with impaired left ventricular function in a carbon monoxide poisoning]. / Syndrome coronaire aigu avec dysfonction ventriculaire gauche lors d'une intoxication au monoxyde de carbone.

Carbon monoxide poisoning is the leading cause of death by poisoning in France. Neuropsychological symptoms are most common. We report on a patient with acute coronary syndrome and transient left ventricular dysfunction in carbon monoxide poisoning. Patient improved under hyperbaric oxygen therapy. Coronary angiography shows no significant lesion leading to myocardial stunning diagnose. Patients exposed to carbon monoxide must have systematic cardiac evaluation with electrocardiogram and dosage of biomarkers.

[Acute anterior myocardial infarction as presenting feature of antiphospholipid syndrome related lupus arthritis]. / Infarctus du myocarde antérieur inaugural révélateur d'un syndrome des antiphospholipides dans le cadre d'une polyarthrite lupique.

INTRODUCTION: Antiphospholipid syndrome is an autoimmune disorder causing venous and arterial thrombosis. Acute coronary complications are rare but potentially dramatic. CASE REPORT: We report a 39-year-old woman who presented with an acute anterior myocardial infarction after intravenous corticosteroids as part of the treatment of lupus arthritis and revealing antiphospholipid syndrome. Emergency coronary angiography was performed with drug-eluting stent angioplasty despite the need for anticoagulation and dual antiplatelet therapy. CONCLUSION: Antiplatelet and anticoagulant therapy management is pivotal in patients with antiphospholipid syndrome and acute coronary syndrome to prevent thrombosis recurrence.

Acute myocardial infarction and coronary artery dissection following rugby-related blunt chest trauma in France.

Coronary artery (CA) dissection following blunt chest trauma is a life-threatening and rare event. Its occurrence in the setting of a contact sport like rugby is even less common. We report on two cases of young adult presenting with segment elevation myocardial infarction related to CA dissection following rugby game. Both were successfully treated with stent implantation. We discuss the mechanism, diagnosis, and optimal management of blunt chest trauma-induced CA dissection.

[Painless anterior acute myocardial infarction in a transplanted heart]. / Infarctus du myocarde antérieur indolore chez un transplanté cardiaque.

Cardiac allograft vasculopathy is the major determinant of long-term survival in patients after heart transplantation. Clinical presentations are congestive heart failure, ventricular arrhythmias and sudden cardiac death. Acute coronary syndrome is a rare presentation of cardiac allograft vasculopathy due to myocardial denervation. We present the case of a 31-year-old patient, who had undergone heart transplantation 6 months earlier and who developed a painless anterior myocardial infarction revealed by syncope. He was successfully treated by percutaneous coronary intervention with drug eluting stent implantation.

[Contribution of cardiac MRI in the initial evaluation and follow-up of myocarditis mimicking acute coronary syndrome: a series of 43 patients]. / Apport de l'IRM cardiaque dans l'évaluation initiale et le suivi des myocardites mimant un syndrome coronaire aigu : à propos d'une série de 43 patients.

AIMS: The diagnosis of acute myocarditis is complex, especially when the clinical presentation mimics an acute coronary syndrome. This condition may promote the progression to dilated cardiomyopathy and the occurrence of severe arrhythmias. A reassessment integrating a cardiac MRI at three months after the acute episode could help identify patients with a poor prognosis. PATIENTS AND RESULTS: This prospective series of 43 consecutive patients hospitalised for acute myocarditis included 36 men and seven women, with a mean age of 32 years, with no indication of heart failure. All patients presented elevated levels of troponin I. Echocardiography showed moderate left ventricular dysfunction in six cases and segmental wall motion abnormalities in 22 cases. After gadolinium injection, a subepicardial late enhancement was observed in 39 cases. Three months after the acute episode, all patients were asymptomatic. The echocardiography and laboratory tests were normal. In 23 cases, the MRI showed persistence of the late enhancement without segmental wall motion abnormality. After a mean follow-up of three years, one patient was lost to follow-up and only one suffered a heart failure revealing a dilated cardiomyopathy complicated by ventricular arrhythmias. CONCLUSION: On admission, the subepicardial localisation of late enhancement in the cardiac MRI is reliable criteria for the diagnosis of acute myocarditis, enabling to rule out an acute coronary syndrome. During follow-up, the persistence of late enhancement has no impact on prognosis. In this series, after a mean follow-up of three years, it was not associated with clinical or paraclinical abnormalities, except in one patient.

[Chronic constrictive pericarditis: new imaging features]. / Péricardite chronique constrictive: apport diagnostique des examens d'imagerie moderne. À propos d'un cas.

We report on a patient hospitalized in cardiology department to explore dyspnea and right ventricular failure evoking constrictive pericarditis. This case is of great interest to review conventional and new imaging features used for the diagnosis of constrictive pericarditis versus restrictive cardiomyopathy.

[Recurrent infective endocarditis. A case report]. / Endocardites infectieuses récidivantes: à propos d'une observation d'endocardite récidivante à streptocoque.

We report the case of a 63-year old patient presenting five infective endocarditis (IE) in a 13-years period, with different types of streptococcus. No entrance way had been found until the last relapse occurring on mitro-aortic bioprosthesis. This recurrence leads to the diagnosis of caecal adenocarcinoma by coloscopy, preceded and guided by PET scanner. It seems to be the initial entrance way which had been unrecognized because of its small size and its particular location, that is very difficult to observe by coloscopy. Recurrent streptococcus IE are rare and severe. When a gut or colic tumor is suspected, PET scan seems to be helpful in etiological survey.
