    ABSTRACT: IntroductionPregnancy can precipitate or exacerbate cardiac arrhythmias. Management of those arrhythmias is not very different from that in non-pregnant women.Objective In this review we tried to specify factors which favour arrhythmias in pregnant women and to show their specific management.Methods We carried out a search through PubMed using as keywords: pregnancy, cardiac arrhythmias, antiarrhythmics.ResultsHemodynamic perturbations, direct electrophysiological effects of hormones and underlying heart disease are potential factors that can promote arrhythmias in pregnancy. Usually, no drug therapy is needed for the management of supraventricular or ventricular premature beats but potential promoting factors should be eliminated. In paroxysmal supraventricular tachycardia, vagal maneuvers should be tried firstly. Adenosine could be used if vagal maneuvers are ineffective. In pregnant women with atrial fibrillation, the goal of treatment is the conversion to sinus rhythm or the control of ventricular rate. Ventricular arrhythmias are usually uncommon during pregnancy and often occur in the absence of structural heart disease and are responsive to drug therapy. Symptomatic bradycardia rarely complicates pregnancy and its management does not differ from that in non-pregnant women.

    ABSTRACT: Rheumatic tricuspid valve dysfunction is the rarest of all valvular disease and is often associated or secondary to left-sided valvular disease. She often realize tricuspid regurgitation. The surgical treatment is generally conservative but also it can be radical generally using bioprotheses. to assess the epidemiology of the rheumatic tricuspid dysfunction, the average diagnoses and its therapeutic. To evaluate the results of the surgical techniques, the factors of prognosis and to determine the therapeutic regarding an in front of important and symptomatic residual tricuspid regurgitation a long time after a valvular surgery first of the left heart. A retrospective, single center of 84 consecutive patients having one significant tricuspid dysfunction regurgitation and/or significant stenosis of rheumatic origin. Hospitalized and followed between January 1992 and March 2008 in cardiology to the hospital Habib Thameur. The prevalence of the rheumatic tricuspid dysfunction was 8.42%. 70% of the patients had a tricuspid regurgitation. The average Age of our patients was 40 years. Our population consisted of 65.5% women. 21% of the patients had benefited at least from a percutaneous mitral dilation. 31% of the patients had antecedents of valvular cardiac surgery. 53% of the patients presented clinical signs of preoperative right cardiac failure and 58% of the patients were in permanent auricular fibrillation. The tricuspid regurgitation was major at 12% of the patients, severe at 88% of the patients, organics at 21% of the patients and functional at 31% of the patients. The average of the systolic pulmonary blood pressure was with 55+-16.8 mm Hg. All the patients had an associated left valvulopathy. The average of the ejection fraction of the left ventricle was 56+12.6%. The dilation of the right cavities was noted at 70% of the patients. The patients of our series were subdivided in two distinct groups. The first group gathers 30 patients who were operated of tricuspid in same operational time as the surgery of the left valves. The surgical gesture on the tricuspid was always conservative. 70% of the patients profited from a tricuspid annuloplasty. Hospital mortality is 10%. 26% of the patients presented a significant residual tricuspid regurgitation after 60 months. 26% of the patients presented late cardiac failure. Late mortality was from 30% to 5 years and 43% to 10 years. The second group is represented by 54 patients not operated on the tricuspid. 30 patients (81%) presented one or more episodes of late cardiac failure. 50% of the patients died during the late follow-up. Among operated patients of the tricuspid, the predictive factors of the residual tricuspid regurgitation post operational are the age<35 years and the mitral disease. The stage NYHA=4 was the only predictive factor of hospital mortality. The predictive factors of late right congestive heart failure postoperative are the clinical signs of preoperative right heart failure and the antecedents of mitral replacement. The predictive factors of late total congestive heart failure postoperative l are the functional tricuspid regurgitation and stage 4 of the NYHA. The benefit of a systematic initial correction of a voluminous tricuspid regurgitation and even of average importance realized prematurely in same operation time that the left valvular gesture was largely shown. The late appearance of functional tricuspid regurgitation after mitral valve surgery is a pejorative marker in the evolution of these patients.

    ABSTRACT: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a primary electrical myocardial disease characterized by exercise- and stress-related ventricular lachycardia manifested as syncope and sudden death usually in child and teenager and was rarely described in adults. The management includes betablockade, with the use of implantable cardioverter defibrillators if medical treatment is insufficient. Report a new case of CPVT. We report a case of a 43 years old patient in whom CPVT diagnosis was made during his exploration for palpitations occurring with the effort. Registration Holter ECG revealed several episodes of supraventricular tachycardia and episodes of nocturnal sino-atrial block. The patient had an ICD and betablockade treatment. The TVPC in adult can manifest with attenuated symptoms that can be summarized with palpitations with the exertion. The supraventricular arrhythmias and sinus dysfunction may be at the forefront of Electrocardiographic manifestations. The prognosis of this form seems better than the TVPC of the child. Treatment with betablockade appears to be effective but existing dysfunction sinus facilitates decision to implant the ICD.

    ABSTRACT: The use of the antivitamines K for more than 50 years, has largely been the proof of its interest: well shown effectiveness, weak cost. However, these drugs are the cause of complications of which most frequent and most serious are the hemorrhagic accidents. To determine the characteristics of the patients hospitalized for grave bleeding under antivitamins K and identify the predictive factors of these accidents. Retrospective study of pilot case type carried out in the service of cardiology of the hospital Habib Thameur of Tunis during the period going from January 2001 to December 2006. It related to a group of 50 patients admitted for "serious haemorrhage under antivitamines K". This group was compared with a reference group including/understanding 100 patients treated by antivitamines K and not having never presented a haemorrhage. The reserved criteria of gravity are the following ones: the location: intracérébrale, rétro péritonéale, articular, intra-ocular with blindness, muscular, subcutaneous if the nasty bruise is voluminous, hematurie, metrorragie, digestive bleeding (high or low), hemoptysie, hemothorax, hemopéricarde; the deglobulisation (fall of the haemoglobin of 2 g/dl or more) requiring or not a transfusion; the necessity of a surgical haemostatic gesture or endoscopique; the transfer in care unit or death. The Middle Age of the patients was of 55 +/- 14 years, the sex ratio was of 0.85. The intermediate duration of the treatment was of 243 +/- 225 weeks. The most frequent indications were the disorder of the supra-ventricular rate/rhythm (72%) and the mechanical valves cardiac (40%). These indications appeared debatable to us at 16% of the patients. One or more supporting factors the hemorrhagic accident were found at half of the patients, the first cause being medicamentous association (20% of the cases). The hématurie was the most frequent complication (28%). The evolution was favorable in all the cases. An internal injury under unclaimed ignored was found at 24% of the patients. The hepatic dysfonction and medicamentous association were in our study of the risk factors of which has occurred of haemorrhage under antivitamines K. In multivariate analysis, medicamentous association was an independent risk factor (Odds ratio adjusted 4.9). At least 50% of the hemorrhagic accidents under antivitamines K are avoidable with the help of a rigorous evaluation of the benefit ratio/risk and a vigilance with respect to medicamentous associations. The creation of centers of anticoagulation in our country is essential in order to improve quality of the clinical and biological monitoring.

    ABSTRACT: The dobutamine echocardiography takes more and more an important place in diagnosis, prognosis and therapeutics strategies of the coronary disease. We prospectively enrolled 130 consecutive patients followed for a coronary insufficiency the aim of determinating the diagnostic value of the dobutamine echocardiography in the myocardial ischemia compared with the classic means as the exercise test and the myocardial scintigraphy. Our results are comparable to the data of the literature, the dobutamine echocardiography is more specific than the exercise test and the myocardial scintigraphy (96 %, 61% and 53 %), more sensitive than exercise test (75 % versus 47 %) but less sensitive than the myocardial scintigraphy (75 % versus 96 %). The stress echocardiography has the best diagnosis precision 87% against 72 % for the scintigraphy and 56 % for the exercise test. The dobutamine echocardiography is a very feasible, tolerated well exam and especially very reliable in term of detection of the coronary disease in the feminine population, with a sensibility at 66,7 %, a specificity at 100 % and a diagnostic precision at 92 %, also in patient with hypertension the stress echocardiography is much more specific and reliable than the exercise test (100 % vs 22 % and 93 % vs 54 %, respectively),and it's superior to the exercise test in the presence of electric signs of systolic excess load and to the myocardial scintigraphy in case of left ventricular hypertrophy. The dobutamine echocardiography can be considered as safety and reliable means of investigation of the coronary insufficiency .

    ABSTRACT: Diabetes represents as independent risk factor for coronary artery disease (CAD) and the prognosis in term of survival rates is worse for diabetic patients who have CAD with report to those with CAD but no diabetes. The coronary artery disease in diabetes has specificities and, in particular, more extensive atherosclerosis. Diabetic patients are also more frequently asymptomatic. Due to the extreme complexity of ischemic vascular disease in patients with diabetes, an optimal therapeutic strategy is based on the correction of elevated blood glucose and lipid levels, of blood pressure, of platelet and coagulation abnormalities. Diabetic patients benefit from secondary prevention by drug therapy(aspirin, lipid lowering with statines, beta blocker and ACE inhibitors) to the same extent as, or more than, non-diabetic patients. Both percutaneous and surgical myocardial revascularization have been proved equally effective for CAD treatment in diabetes. A recent randomized trial has shown a significantly improved outcome after surgical revascularization. But, the effects of drug-eluting stents, which dramatically decrease the incidence of re-stenosis, seem promising.

    ABSTRACT: To evaluate the predictive factors of significant coronary stenosis in women, we have studied retrospectively data from 230 women explored by coronary angiography. The population has been divided in 2 groups: one (G1) without significant coronary lesions; the second (G2) having at least one significant coronary stenosis (> 50%). The prevalence of the significant disease was 54.3%. Coronary risk factors associated with a significant disease were : age > 55 years, diabetes mellitus, menopause, high lipid levels, and the association of at least 3 risk factors. Typical angina and history of myocardial infarction were significantly more prevalent in the G2 as like as Q necrosis wave, ST segment modifications percritically and premature ventricular beats. A regional abnormal wall motion at rest echocardiography was independently associated with significant coronary artery lesions (OR = 7.35). Using these data we have established a score of prediction of significant disease in women. This score aided to classify our female patients into different levels of risk and to better indicate subsequent explorations. Thus. with a good evaluation of the clinical and at rest data in women, we could obtain a more accurate degree of suspicion of a significant coronary artery disease before the indication of a coronary angiography.

    ABSTRACT: Conductive disorders following open-heart valvular surgery represent serious complications that may require definitive pacemaker implantation. The natural history of these troubles is not well established thus, controversy persist concerning the timing of pacemaker implantation. In this study we identify the predictive factors of permanent conductive disorders in order to assess the optimal time of pacing. Two hundred thirty valvular replacements were done between 1993 and 2003. The mean age of our patients was 42 +/- 13.4 years. Rheumatic valvulopathies accounted for 76% of cases, with 54% of multiple valvulopathies. Twenty-two patients (9,5%) had an early postoperative conductive disorder, 9 of them (4%) were definitively implanted after a mean delay of 31.8 days. Preoperative bifascicular bloc and early installation of postoperative high-grade conduction disturbances and its persistence for more than 48 hours are significantly associated with permanent postoperative conductive disorders (respectively P = 0.04 and = 0.03). Aortic valve surgery and infective endocarditis were more frequent in the implanted group but the difference was not significant. After open-heart valvular surgery; predictive factors of definitive conductive troubles justify an earlier pacemaker implantation. This attitude may accelerate the hospital discharge and decrease the disease cost effectiveness.

    ABSTRACT: The double chambered right ventricle is a rare congenital abnormality. It creates an obstacle for the right ventricular ejection. The cardiac ultra sonography examination allows the diagnosis in most majority of cases. The angiography is performed in difficult cases. We report 3 cases of infundibular stenosis with normal interventricular septum. The diagnosis was suspected for the 3 cases by the constellation of clinical findings pointing to systolic murmur over the precordium, and the electrocardiography showing right ventricular hypertrophy. It is confirmed by the echocardiogram and the hemodynamic exploration with a trans stenotic gradient evaluated at 72,80 and 80mmHg. The 3 patients underwent surgery and had all good post operative follow up. These 3 observations allow us to recall the epidemiological, embryological, clinical and echocardiographic particularities of pure infundibular stenosis and to determin the adequate treatment and the prognosis.

    ABSTRACT: Freidreich ataxia is the most frequent ataxia of early onset and of autosomal recessive transmission. It is associated with hypertrophic cardiomyopathy in 34 to 77% of cases. The purpose of this article is to describe the cardiac manifestations of two patients affected by this disease. The first case report is about a 34-years-old, bedridden male patient having muscular hypotony and osteotendinous areflexia of the lower limbs. Chest x-ray findings showed a cardiac silhouette distorted by scoliokyphosis. ECG revealed frequent auricular extrasystoles. Cardiac US examination disclosed a pattern of concentric hypertrophic cardiomyopathy with systolic and diastolic dysfonction.

    ABSTRACT: Introduced in 1989, the myocardial doppler tissue imaging has now many clinical applications. Doppler tissue imaging explores the proper systolic and diastolic regional function of myocardial fibers. We can measure myocardial velocities by recording signals of low velocitiy and high magnitude, the strain and the strain rate are then derived from velocities. Specific software is therefore necessary. There are many ways of recording and representing myocardial doppler tissue parameters. Diagnostic and prognostic value of myocardial doppler tissue imaging is now proved and this method has many applications in ischemic cardiopathy and in cardiomyopathies. The development of powerful software is promising for the applications of the strain in the future.

    ABSTRACT: We aim at analysing the increase of CVDs in the Tunisian hospitals in order to assess the burden of NCDs in the transitional context. Data are recorded through the Tunisian National Morbidity and Mortality Survey (TNMMS). In order to assess the CVDs (CHDs vs RHDs) trend, two representative samples of Cardiology Departements patients were compared one is selected from the TNMMS and the second from the hospitalisations recorded in 1992. Causes, stay duration, status at the end of the hospitalisation, transfer to another hospital and patients socio-demographic characteristics are recorded and compared for the two periods. All the diagnosis are coded referring to the DMC 10. To analyze the determinant of the epidemiological transition, we have elaborated the CVD causal pattern and we have documented all their determinants. CHD rate has dramatically increased, while RHD has decreased especially on men. In 1992, 39.2% of men and 11.8% of women were admitted for CHD. In 2002, these rate are respectivly 58.8% and 38.2% while RHD rates were, in 1992, 11.8% on men and 25.3% on women vs 4.4% and 11.7% respectively. This study has confirmed that so far controlling transmitted diseases seems to be successful, Tunisian people are about to face a new problems as hypertension, obesity, diabetes and tobacco smoking. The new challenge with the burden of diseases requires the implementation of a national strategy relevant to the epidemiological, social and economical transition. Population needs and cost effectiveness of interventions assessment is crucial to set the national priorities.

    ABSTRACT: We aimed to assess the acute myocardial infarction management in Tunis public hospitals during one year (from March 2000 to February 2001). A standard questionnaire was designed to record prospective data on 740 patients with a follow up during 28 days. Multivariate analysis was performed using the logistic regression model with all-factors as well as age, gender, CHD risk factors as predictors of the delay and fatality. 54% of patients were admitted during the first 6 hours after the onset of symptoms. In multivariate analysis, the delay of consultation is significantly correlated with gender (OR = 2.3, p < 0.001), age (OR = 1.02, p < 0.01) and health insurance (OR = 1.5, p < 0.01). 90% of patients consulted in emergency wards. The emergency ambulance transported 19.6% of patients. 48% of patients underwent early revascularisation of thrombolysis, 51% on men vs 31% on women (p < 0.01). The fatality rate was higher on women 14% vs 6.4% on men (p < 0.01) at 5 days and 27.2% vs 13.6% at 28 days. In multivariate analysis, the principal fatality predictive factor was age (RR = 1.08, p < 0.001) and delay (2.56 p < 0.001) and tobacco smoking (RR = 2.83, p < 0.0001). This study highlighted the problem of acute myocardial infarction management in public hospitals in Tunisia and it constitutes a baseline to assess different interventions focusing on cardiovascular diseases control and surveillance.

    ABSTRACT: This a retrospective study on 46 patients conducted over a 9-year period. These patients had an acute myocardial infarctus (AMI) confirmed wilth changes on the electrocardiogram and raised cardiac enzymes. However, the subsequent coronary angiography showed normal in all these patients. The purpose of our study is to assess epidemiologic, clinical, pronostic and therapeutic features of AMI with angiographically normal coronary arteries and compare the results obtained with those of AMI with coronary artery disease. AMI with angiographically normal coronary arteries is a first coronary event in young patients (mean age 47.7 years) having few coronary risk factors (54.3% have only one risk factor) mainly smoking (73.9%). The anterior location is prevalent. The patients with AMI and angiographically normal coronary arteries have a better prognosis than those with coronary artery stenosis. Indeed, their left ventricular function is unaltered (mean ejection fraction 48.7%). Hypokinesis is the most frequent abnormality of wall motion noticed. The patients' post infarction course is bengin when the coronary arteries are angiographically normal. The incidence of hemodynamic complications and ischemic recurrences are lower than in AMI with coronary stenosis. The choice treatment remains fibrinolysis.
