Enhancing Arrhythmogenic Right Ventricular Cardiomyopathy Detection and Risk Stratification: Insights from Advanced Echocardiographic Techniques.

Introduction: The echocardiographic diagnosis criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) are highly specific but sensitivity is low, especially in the early stages of the disease. The role of echocardiographic strain in ARVC has not been fully elucidated, although prior studies suggest that it can improve the detection of subtle functional abnormalities. The purposes of the study were to determine whether these advanced measures of right ventricular (RV) dysfunction on echocardiogram, including RV strain, increase diagnostic value for ARVC disease detection and to evaluate the association of echocardiographic parameters with arrhythmic outcomes.

Background: knowing the risk factors and clinical manifestations of coronary artery disease (CAD) allows us to intervene more effectively with a particular population.

Objective: to identify clinical and angiographic profiles of patients undergoing cardiac catheterization, treated at a tertiary hospital and treated by percutaneous coronary interventions (PCI).

Methods: the study of 1,282 patients who underwent 1,410 cardiac catheterizations, selected from March/2007 to May/2008 from a database in a general hospital for diagnosis of coronary artery disease (CAD).
