Design and Rationale of the National Tunisian Registry of Percutaneous Coronary Intervention: Protocol for a Prospective Multicenter Observational Study.

Background: Coronary artery diseases remain the leading cause of death in the world. The management of this condition has improved remarkably in the recent years owing to the development of new technical tools and multicentric registries.

Objective: The aim of this study is to investigate the in-hospital and 1-year clinical outcomes of patients treated with percutaneous coronary intervention (PCI) in Tunisia.

Current and new imaging techniques in risk stratification of asymptomatic severe aortic stenosis.

Aortic stenosis (AS) is one of the most common valvular diseases in clinical practice. The prevalence of calcified AS with moderate or severe stenosis exceeds 2% after 75 years. The optimal timing of intervention for asymptomatic severe AS is uncertain and controversial.

Risk stratification for sudden cardiac death in patients with heart failure : Emerging role of imaging parameters.

Background: Heart failure with reduced ejection fraction is a common condition that has a poor prognosis. Accurate selection of patients with ischemic heart disease and idiopathic dilated cardiomyopathy, who are at risk of sudden cardiac death (SCD), remains a challenge. In these cases, current indications for implantable cardioverter-defibrillators (ICD) rely almost entirely on left ventricular ejection fraction.

A giant calcified aneurysm of the basal inferior wall: a rare phenomenon.

Left ventricular aneurysms (LVA) are mainly a late consequence of transmural myocardial infarction. Approximately 80% of LVA are located in the anterior and/or apical walls, most commonly associated with left anterior descending artery occlusion but any region may be engaged. Basal inferior wall aneurysms are rare and constitute nearly 3% of all LVA.

Coronary PCI revascularization novel treatment of bundle branch reentrant ventricular tachycardia.

Bundle branch reentrant ventricular tachycardia (VT) is a form of macroreentrant tachycardia. Although infrequent in occurrence, this arrhythmia presents with serious clinical manifestations and has potential for cure by catheter ablation. We report a case of bundle branch reentrant VT with ischemic source.

Hypertension and Atrial Fibrillation: What is the prevalence of obstructive sleep apnea syndrome?

Introduction: Obstructive sleep apnea-hypopnea syndrome (OSAS) and cardiovascular disease are public health problems. The objective of our study was to evaluate the frequency of OSAS in patients with hypertension and atrial fibrillation (AF) and to investigate the factors associated with OSAS in this population.

Methods: It's a cross-sectional study including 73patients with hypertension and AF.

Percutaneous Coronary Intervention of Chronic Total Occlusions in Patients With Low Left Ventricular Ejection Fraction.

Objectives: The study sought to assess the outcome of percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) in patients with low left ventricular ejection fraction (LVEF) (≤35%).

Background: Data regarding the outcome of PCI in patients with low LVEF affected by CTO are scarcely reported.

Methods: The authors performed a prospective longitudinal multicenter study including consecutive patients undergoing elective PCI of CTOs.

A cardiac hydatid cyst underlying pulmonary embolism: a case report.

Hydatid cysts located in the interatrial septum are especially rare but when they occur, they might cause intracavity rupture. We report on a patient with acute pulmonary embolism caused by an isolated, ruptured hydatid cyst on the right side of the interatrial septum. A 16-year-old-boy with an uneventful history was hospitalized for exercise-induced dyspnea and blood expectorations.
