He was also a practical man endowed with dexterity, smartness, and common sense. For him, performing a catheter intervention in contrast to surgery was like playing the clarinet in contrast to playing the piano. It was easier but it still required talent and proper training to become a professional.
Playing the piano means using all ten fingers at the same time and having 88 keys to choose from for every single finger, not to mention the simultaneous work on the foot pedals.

A clarinet also requires the use of all ten fingers but each finger has just a single exceptionally up to five allotted function. Clarinet players may forgive my not mentioning the importance of the mouthpiece. The analogy is just to make a point. The cardiac surgeon works three-dimensionally with every stitch, every cut, and every suture having to meet quality requirements and representing his or her level of art.
Performing a catheter intervention, on the other hand, only permits one to advance, retract, turn right, or turn left, one, two, or at the most three different instruments at a time.
Yet, while the surgeon has a true three-dimensional field of vision, a catheter operator has to imagine the third dimension looking at a two-dimensional black and white picture.
