Coronary CT Angiography Can Be Used As a Substitute for Coronary Angiography in Patients With Significant LV Dysfunction

Heart failure is a complex and progressive disease that leads to significant morbidity and mortality. The clinical manifestations of heart failure may result from a variety of disorders, although ischemic heart disease is the leading cause in Western society. Due to the fact that patients with ischemic heart disease benefit from revascularization, evaluation for obstructive coronary artery disease is recommended in this select population. Traditionally, invasive coronary angiography has been used for evaluation of obstructive coronary disease, however recently coronary computed tomography angiography (CCTA) has emerged as an attractive non-invasive method for the evaluation of coronary arteries. The benefits of CCTA in evaluation of select individuals with heart failure will be summarized in this article.
