Objectives: After studying the article entitled “An Echocardiographic Presentation of Severe Dilated Cardiomyopathy due to Acute Viral Myocarditis From Coxsackie B Enterovirus,” you will be able to:
Understand viral infection is a common cause of dilated cardiomyopathy
Identify the presentation of dilated cardiomyopathy on echocardiography
Describe the role of echocardiography in the diagnosis of viral myocarditis from Coxsackie B virus
What is the most common etiology of myocarditis in developed countries? Autoimmune disease Bacteria Fungus Virus
Which type of virus is Coxsackie B? Varicella-Zoster Enterovirus Poxvirus Epstein-Barr
What is the second phase of the pathophysiologic process of viral myocarditis? Activation of the host immune system Acute viral infection Direct cytotoxic destruction Chronic myocardial injury
Which type of cardiomyopathy results from an inflammatory response that causes fibrotic changes within the myocardium and eventual myocyte necrosis? Hypertrophic Unclassified Dilated Restrictive
What is the goal of treatment for a patient with acute heart failure? Increase volume overload Normalize left ventricular filling pressures Decrease peripheral vasodilation Increase left ventricular contractility
Which echocardiographic finding is more likely associated with fulminant myocarditis? Increased left ventricular wall thickness Left ventricular diastolic dysfunction Increase in left ventricular mass Elevated left atrial pressure
What is an essential parameter in the assessment of left ventricular diastolic function? Spectral Doppler Biplane ejection fraction Tissue Doppler imaging Mitral inflow deceleration time
