Abstract:
Holmes' heart, a rare variant of double-inlet left ventricle with rudimentary right ventricle and ventriculoarterial concordance, predisposes to pulmonary overcirculation and heart failure due to unrestricted shunting. We report the case of a 32-year-old male, in whom cardiac magnetic resonance (CMR) revealed Holmes' heart with marked pulmonary artery dilation and advanced heart failure after long-term clinical management. This case highlights the value of CMR in characterizing complex anatomy and reinforces the importance of early surgical palliation to prevent late decompensation.

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...
