Coronary Angiography Discovery (1958): Cardiology Milestones Throughout History (Part 6)
Dr. F. Mason Sones Jr. accidentally discovered coronary angiography, a technique for visualizing the coronary arteries, which became essential for diagnosing and treating coronary artery disease.
Known as the father of coronary angiography, Dr. F. Mason Sones Jr. (1918-1985) was a pioneering cardiologist whose accidental discovery of coronary angiography in 1958 revolutionized cardiology. This breakthrough at the Cleveland Clinic allowed for the first clear visualization of coronary arteries in living patients, leading to advances in coronary artery bypass surgery and interventional cardiology. Before his work, diagnosing and treating coronary artery disease was extremely challenging. This serendipitous discovery provided the first clear visualization of coronary arteries in living patients, enabling accurate diagnosis and targeted treatment. Today, over 3 million coronary angiograms are performed annually worldwide, reflecting the lasting impact of his contribution.
Cardiology, the study of the heart and its functions, has a rich history with numerous milestones that have significantly advanced our understanding and treatment of heart diseases.
Over the next few weeks, we’re going to highlight some interesting historical facts about key cardiology milestones.
