Abstract:
The increasing number of cancer survivors has highlighted the long-term cardiovascular implications of cancer treatment. Despite improvements in thoracic radiation therapy (RT) and cardiac sparing techniques, associated cardiovascular disease, most notably valvular heart disease (VHD), poses a significant challenge for cancer survivors. This systematic review examines the pathophysiology, prevalence, diagnosis, and treatment of VHD in cancer patients, with a focus on RT-related VHD, emphasizing the need for active surveillance and multidisciplinary care. The incidence of VHD increases over time post-radiation exposure. Valve regurgitation is more common than stenosis, with the aortic valve being most frequently affected.

Imaging Studies for Cardiovascular System III: X-Ray
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...
