Core Tip

Core tip: Radiation-induced cardiovascular disease is a common complication of mediastinal radiotherapy and often occurs years or decades after treatment. It most commonly manifests as chronic pericarditis, cardiomyopathy, and valvular or coronary heart disease. Its pathophysiology is chiefly that of radiation fibrosis, fueled by chronic states of inflammation and oxidative stress. Conventional risk factors impose additive risk to these patients and must be addressed as early as possible. Development of more sensitive imaging modalities is enabling detection at earlier stages of the disease and creating opportunities for novel treatment strategies. Percutaneous interventions have an increasing role in the treatment of symptomatic vascular and valvular disease.
