A cardiac surgeon is a medical professional who is experienced and skilled in treating heart problems, disorders, diseases, and conditions. They can diagnose certain heart problems and treat them with surgery. They work closely with other medical professionals, such as primary care doctors and cardiologists. Cardiac surgeons often perform surgeries to correct heart problems and heart disease, but they can also work on other areas in the chest.

Interventional radiology, which is also referred to as vascular and interventional radiology, uses minimally invasive radiology both to treat and diagnose diseases, disorders, and other problems a wide variety of patients may face. Generally, doctors in this subspecialty want to make the procedures they perform as minimally invasive as possible, as this reduces the possibility of other problems and complications. Physicians usually learn about interventional radiology while they are completing their residencies.
