Prosthetic valve endocarditis: clinical, bacteriological and therapeutic aspects.

BACKGROUND: The prosthetic valve endocarditis(PVE) is a serious complication of valve replacement surgery. The aim of this work was to analyze the clinical and echocardiography characters of the PVE, deduce surgery indication, and determinate the prognostic factors Methods :We presented a retrospective descriptive study from 2000 to 2014 which included 30 patients hospitalized in department of cardiology in la Rabta hospital for certain PVE according to DUCKES criteria. RESULTS: Our study consisted of 18 male patients with sex ratio of 1.5 ,the mean age was 44 years; These PVE were early in 6 cases and delayed in 24 cases. Fever was present in 28 patients..splénomegaly was present in 7 patients and cutaneous signs were present in 6 patients Blood cultures were negatives in 16 patients .Staphylococcus was isolated in 7 cases (23.3%), a streptococcus in 5 cases (16.6%), a gram negative bacillus in 1 case (3, 3%) and one enterococci in 1 case (3.3%).The transesophageal and transthoracic echocardiography performed in all patients showed vegetation for 17 patients, a Dishence of prosthetic valve in 14 patients, prosthesis obstruction in two patients and annular abscess in 4 patients . 22 complications were reported in 21 patients; il was an hemodynamic complication in 13 cases , a septic complication (uncontrolled infection ) in three patients, embolic complication (ischemic transit stroke ) in 4 cases and mixed (hemodynamic and septic) in one patient. The indication for surgery was retained in 18 patients; the need for early surgery was because of congestive heart failure in 14 patients and uncontrolled infection in 4 patients ; but it was performed in 13cases with a period between 1 and 30 days the operation the global mortality was about 30%. he predictors factors of mortality released from our study are: the early character of EPV, heart failure, uncontrolled infection, staphylococcal endocarditis and dishence of prosthesis with significant regurgitation. CONCLUSION: PVE is still a serious complication leading to high mortality . Combined medical and surgical treatment is recommended.

Design and Rationale of the National Tunisian Registry of Heart Failure (NATURE-HF): Protocol for a Multicenter Registry Study.

BACKGROUND: The frequency of heart failure (HF) in Tunisia is on the rise and has now become a public health concern. This is mainly due to an aging Tunisian population (Tunisia has one of the oldest populations in Africa as well as the highest life expectancy in the continent) and an increase in coronary artery disease and hypertension. However, no extensive data are available on demographic characteristics, prognosis, and quality of care of patients with HF in Tunisia (nor in North Africa). OBJECTIVE: The aim of this study was to analyze, follow, and evaluate patients with HF in a large nation-wide multicenter trial. METHODS: A total of 1700 patients with HF diagnosed by the investigator will be included in the National Tunisian Registry of Heart Failure study (NATURE-HF). Patients must visit the cardiology clinic 1, 3, and 12 months after study inclusion. This follow-up is provided by the investigator. All data are collected via the DACIMA Clinical Suite web interface. RESULTS: At the end of the study, we will note the occurrence of cardiovascular death (sudden death, coronary artery disease, refractory HF, stroke), death from any cause (cardiovascular and noncardiovascular), and the occurrence of a rehospitalization episode for an HF relapse during the follow-up period. Based on these data, we will evaluate the demographic characteristics of the study patients, the characteristics of pathological antecedents, and symptomatic and clinical features of HF. In addition, we will report the paraclinical examination findings such as the laboratory standard parameters and brain natriuretic peptides, electrocardiogram or 24-hour Holter monitoring, echocardiography, and coronarography. We will also provide a description of the therapeutic environment and therapeutic changes that occur during the 1-year follow-up of patients, adverse events following medical treatment and intervention during the 3- and 12-month follow-up, the evaluation of left ventricular ejection fraction during the 3- and 12-month follow-up, the overall rate of rehospitalization over the 1-year follow-up for an HF relapse, and the rate of rehospitalization during the first 3 months after inclusion into the study. CONCLUSIONS: The NATURE-HF study will fill a significant gap in the dynamic landscape of HF care and research. It will provide unique and necessary data on the management and outcomes of patients with HF. This study will yield the largest contemporary longitudinal cohort of patients with HF in Tunisia.

A giant aneurysm of the left anterior descending coronary artery in the setting of Behcet's disease.

Behcet's disease is a chronic inflammatory syndrome that can affect arteries and veins of all sizes and is an unusual cause of myocardial infarction. We report a case of a 42-year-old male with no cardiovascular risk factors who was referred to our department for a spontaneously resolving anterior ST-elevation myocardial infarction. Clinical and biological investigations revealed a high probability for Behcet's disease. The coronary angiogram showed severe left main artery stenosis with a huge coronary aneurysm of the proximal left anterior descending coronary artery, which was treated by aneurysm resection and coronary artery bypass grafting. Inflammatory arteritis should be considered in young patients with low cardiovascular risk presenting with acute coronary syndrome.
