Diagnostic dilemma in a middle-aged man with heart failure
Abstract:
We report a middle-age man presented with shortness of breath. Echocardiography revealed globally hypokinetic LV with poor function. Coronary angiograms showed no obstructive coronary artery lesions but multiple coronary fistulae to pulmonary artery without significant left to right shunt. Cardiac magnetic resonance imaging demonstrated normal myocardial perfusion and absence of myocardial scarring. His condition improved with medications with fistulae left untreated. This case illustrates the importance of functional assessment of a rare clinical condition (coronary fistula) in patients with common clinical presentation (congestive heart failure) prior to definitive treatment.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
