The first coronary angioplasty was performed by which inventor in 1977?

Explanation:
The question tests who first performed a coronary angioplasty. Andreas Gruentzig, a German physician, carried out the first successful coronary balloon angioplasty in 1977, using a balloon catheter to dilate a narrowed coronary artery. This milestone established percutaneous coronary intervention as a therapeutic option for coronary artery disease. The other names contributed in related areas—Charles Dotter pioneered peripheral transluminal angioplasty, Mason Sones popularized selective coronary angiography, and Sven-Ivar Seldinger developed the vascular access technique—but none were the first to perform a coronary angioplasty in 1977.
