"2-chlorobenzylidene malononitrile" also named CS gas is the most used riot-control agent in the world. Its reputation as the least toxic tear gas explains its large use by different authorities. Early exposure to CS spray commonly induces visual irritation, skin reactions, with increased mucous secretion in order to temporarily incapacitate targeted people. However, there is a large agreement that safety data of this product is limited and further studies need to be performed since serious problems could occur after heavy exposure such as loss of consciousness, laryngospasm, pulmonary edema and hemorrhage... Herein, we report a case of a young man who had acute myocardial infarction with serious cardiac sequelae after exposure to tear gas. To our knowledge, this is the second case since forty years in the literature that directly links documented acute heart infarction to CS gas exposure.

Primary tumors of the heart are uncommon. 75% of these tumors in the adult are benign and 25% are malignant. Angiosarcoma was the most frequent malignant tumour. 75% occurred on the right side, especially in the right atrial. This tumour was generally discovered in post-mortem because the non specificity of functional symptomatology. Echocardiography is the first non invasive tool for diagnosis and evaluation of cardiac mass. Angiosarcoma was associated with an unfavourable outcome. We reported a case of an atrial angiosarcoma revealed by transoesophageal echocardiography in a 42 years old woman.

Hypereosinophilic syndrome (HES) is defined as a prolonged, unexplained peripheral eosinophilia. Endomyocardial fibrosis and mural thrombus formation are common occurrences such that patients are exposed to lethal thromboembolic complications. The valvular damage described is mainly related to iterative valve thromboses that are amenable to surgery. Here, the case is reported of a 39-year-old woman suffering from HES with mitral valve thrombosis and mechanical prosthetic mitral valve replacement, in whom a new thrombosis of the inserted prosthesis occurred one month postoperatively, concomitant with severe hypereosinophilia and despite adequate anticoagulation. The patient had received a new bioprosthetic mitral valve replacement, and her eosinophil count had been normalized after treatment with corticosteroids. Oral anticoagulation with warfarin was maintained. Subsequently, no recurrent thromboembolic events were reported, and echocardiography performed at the one-year follow up showed the bioprosthesis to have a normal hemodynamic profile.

Background: Right ventricular (RV) involvement in obstructive sleep apnea syndrome (OAS) is controversial. The aim of this study was to determine a correlation between echocardiographic parameters of RV function and severity of OSA assessed by the apnea- hypopnea index (AHI). Methods: Sixty patients with suspected OSA were enrolled. All patients had overnight polygraphy and an echocardiographic assessment of RV structure and function. Patients were divided into three groups: a control group (n=20) with an AHI<5/h, a group of mild to moderate OSA (n=18) with an AHI=5-30/h and a group of severe OSA (n=22) with AHI≥30/h. Results: There were no differences of age, body mass index and sex among the three groups. There was no difference in systolic pulmonary pressure. RV free wall thickness, end-diastolic surface and right atrium surface were statistically higher in OSA patients compared with controls. The peak systolic myocardial velocity at tricuspid lateral annulus S' were significantly lower in patients compared with controls (14.5±3 vs 12.2±2 cm / s, p<0.001; respectively). This decrease was greater in patients with severe OSA compared with mild to moderate OSA (11.4±3 vs 13.0±1 cm/s, p=0.05, respectively). Right ventricular myocardial performance index (MPI) was significantly higher in OSA compared with controls (0.55±0.12 vs 0.46±0.14, p=0.024, respectively) but it was not correlated with the severity of IAH. Conclusions: In OSA patients, there was a significant RV dysfunction independently of pulmonary pressure, although the correlation with the severity of IAH was moderate.

Les tumeurs primitives du coeur sont rares.75 % de ces tumeurs chez l'adulte sont benignes et 25 % sont malignes. L'angiosarcome est la tumeur maligne la plus frequente. Dons 75% des cas, il se developpe dans les cavites cardiaques droites, essentiellement dans l'oreillette droite. Cette tumeur est le plus souvent decouverte en post- mortem et rarement en ante-mortem du a la non specificite de la symptomatologie fonctionnelle. L' echocardiographie est l'examen non invasif de premiere intention pour le diagnostic et l'evaluation d'une masse cardiaque. Son pronostic a court terme est en general fatal. Nous rapportons l'observation d'un angiosarcome de l'oreillette droite chez une patiente âgee de 42 ans revele par l'echographie trans- oesophagienne.

Cardiac involvement may occur with or without clinical manifestations and is considered as a major prognostic factor. To analyze the clinical features of cardiac involvement, to review actual knowledgement concerning echocardiographic diagnostic and to evaluate recent advances in treatment of the disease. An electronic search of the relevant literature was carried out using Medline and Pubmed. Keys words used for the final search were amyloidosis, cardiopathy and echocardiography. We considered for analysis reviews, studies and articles between 1990 and 2007. Amyloidosis represents 5 to 10% of non ischemic cardiomyoparhies. Cardiac involvement is the first cause of restrictive cardiomyopathy witch must be evoked in front of every inexplained cardiopathy after the age of forty. The amyloid natur...

Evaluation of left ventricular systolic function, usually based on the assessment of the ejection fraction, is increasingly supplemented by other more sophisticated techniques such as 3D echocardiography and speckle tracking. However these methods require a high technicity and a good echogenicity. As heart failure leads to lengthening of aortic pre-ejectional time (PET) and shortening of left ventricular ejection time (ET), systolic time intervals (STI) were proposed for the evaluation of systolic myocardial performance. to establish a correlation between left ventricular ejection fraction (LVEF) and STI and determine a cut-off value of PET/ET ratio to diagnose a LVEF inferior to 35%. 109 consecutive patients referred to two echocardiographic laboratories had measurements of STI and LVEF estimated by Simpson biplane method. Patients included were in sinus rhythm with a heart rate<100 beats per minute. Patients with atrial fibrillation, pacemaker or prosthetic valves were excluded...

Ther is no clinical radiographical electrocardio graphical symptom to characterize this Kind of Cardiac failure. It's diagnosis and its valuation could be done with doppler chocardiography.
