The Day Interventional Cardiology Was Born

Did you know? On this day in 1977, cardiology changed forever. 🫀

September 16, 1977 marked the first successful human coronary balloon angioplasty.

In Zurich, Dr. Andreas Grüntzig performed the procedure on a 37-year-old man with severe coronary artery stenosis, opening the artery without open-heart surgery.

The idea seemed almost impossible at the time: could you treat a coronary blockage from inside the artery?

Dr. Grüntzig pursued the idea relentlessly, developing early balloon-catheter prototypes with the help of a retired chemist and even working with PVC materials in his home.

On that historic day, he advanced a small balloon catheter into the coronary artery and inflated it across the stenosis.

The narrowed artery opened.

It was a radical idea at the time:

That single procedure helped launch the era of modern coronary intervention.

Today, balloon angioplasty and stents are routine parts of heart care.

True innovation sometimes starts with an idea that sounds impossible. 🫀

Never underestimate the “random guy in a garage.”
