Theoretically, DEB sight to eliminate stent thrombosis and reduce restenosis rates by leaving no metal behind.

Aim: To compare the results of angioplasty of de novo lesions by DEB (SEQUENT PLEASE) versus DES (Promus Premier and Promus Elite) in a Tunisian population.

Early detection of left atrial dysfunction in hypertensive patients: Role of Speckle Tracking imaging.

Introduction: Systemic hypertension is a major health problem worldwide, it is associated with impaired left atrial (LA) function. Myocardial deformation analysis using speckle-tracking echocardiography has emerged as a promising tool to evaluate atrial deformation and function.

Aim: To evaluate early changes in left atrial longitudinal strain based on speckle tracking echocardiography in patients with hypertension.

New onset of sinoatrial block in a young patient treated with systemic meglumine antimoniate.

The sinoatrial block is a new side effect of meglumine antimoniate. Prompt interruption of the drug results in the normalization of electrographic changes and prevents sudden cardiac arrest.

Cardiac tamponade: an uncommon presenting feature of systemic lupus erythematosus (a case-based review).

Although pericarditis is the most prevalent cardiac involvement in systemic lupus erythematosus (SLE), cardiac tamponade is extremely infrequent notably as the first manifestation of the disease. Here we report the case of a 22-year-old woman presenting with cardiac tamponade as the initial presentation of SLE.

[Right ventricular function after a first episode of pulmonary embolism: Contribution of longitudinal 2D strain].

Background: Analysis of right ventricular (RV) function during the acute phase of pulmonary embolism (PE) was widely reported in the literature. However, few studies analysed its function long term after the acute phase. Our aim was to evaluate the RV function long term after a first episode of PE.

Clinical Outcomes of Patients Treated With the Bioresorbable Scaffold.

Introduction: Bioresorbable scaffold (BRS) is a novel device to treat coronary lesions. It may induce a revolution in percutaneous coronary intervention (PCI) and a novel treatment termed vascular restoration therapy. These devices provide short-term scaffolding of the vessel and then dissolve, which would treat the plaque and coronary lumen without inflicting a permanent foreign body in the coronary artery.

Stent implantation for ostial left anterior descending coronary artery stenosis: clinical particularities, therapeutic strategies, and medium-term outcomes.

Background: The stenosis of the ostial left anterior descending artery represents one of the challenges for the interventional cardiologist. The aim of our study was to define the characteristics of this population and to analyze their results in medium term.

Methods: We had undertaken a retrospective study of 76 patients treated in the Cardiology Department of the Military Hospital of Tunis, between January 2014 and March 2017.

Design and Rationale of the National Tunisian Registry of Atrial Fibrillation: Protocol for a Prospective, Multicenter Trial.

Background: Atrial fibrillation (AF) is an important health problem in Tunisia. A significant change in the epidemiological pattern of heart disease has been seen in the last 3 decades; however, no large prospective multicenter trial reflecting national data has been published so far. Robust data on the contemporary epidemiological profile and management of AF patients in Tunisia are limited.

Multimodality imaging assessment of a caseous calcification of the mitral valve annulus.

Caseous calcification of the mitral annulus (CCMA) is a rare echocardiographic finding. It is commonly misdiagnosed as an abscess, tumor or infective vegetation on the mitral valve. Since it is a benign process, differentiating it from malignant intra-cardiac mass is primordial to avoid unnecessary surgery.

Association of FV G1691A Polymorphism but not A4070G With Coronary Artery Disease.

Coronary artery disease (CAD) is one of the chief causes of death in the world. Several hypotheses have been promoted as for the origin of the disease, among which are genetic predispositions and/or environmental factors. The aim of this study was to determine the effect of factor V (FV) gene polymorphisms (Leiden, G1691A [FVL] and HR2 A4070G) and to analyze their association with traditional risk factors in assessing the risk of CAD.

[Giant cell tumors of the tendon sheaths of the hand: about 50 cases].

Giant cell tumors of the synovial tendon sheaths (GCTSTS) are a localized form of hemopigmented villonodular synovitis. They mainly affect the hands. This study aims to analyse the epidemiology, clinical and therapeutic characteristics of GCTSTS, to assess the results of surgical treatment and to identify risk factors for recurrences.

Contribution of cardiac magnetic resonance imaging in the diagnosis of acute coronary syndrome with normal coronary angiography.

Background - Acute coronary syndrome with high level of troponin is a common pattern for emergency consultation. In 10% of cases, coronary angiography concluded that there were no significant coronary lesions.
