Which figure is known as the 'Father of Intervention' and described in 1964 methods using stiff dilators to gradually enlarge diseased peripheral vessels?

• A. Charles Dotter
• B. Andreas Gruentzig
• C. Mason Sones
• D. Werner Forsman

Answer: (A)

The main idea is the birth of catheter-based vascular intervention. Charles Dotter pioneered percutaneous transluminal angioplasty and is known as the father of interventional radiology. In 1964 he described using stiff dilators and coaxial catheters to gradually enlarge diseased peripheral vessels, effectively performing the first endovascular dilations. This approach demonstrated that we could treat vascular disease without open surgery, laying the groundwork for all later catheter-based interventions. Andreas Gruentzig later popularized balloon angioplasty in the coronary arteries, earning him recognition in interventional cardiology, but his work built on Dotter’s peripheral techniques and introduced balloons as the dilating tool. Mason Sones is famous for developing selective coronary angiography, and Werner Forssman performed the first human cardiac catheterization.
