Just recently in the news too is the new medical school with simulators so perhaps 
this procedure can be maximized through training. The new facility was financed through private philanthropy, debt and school resources. Unlike using the femoral artery in the leg, which almost guarantees and overnight stay for observation, going in via the wrist is a lot easier on the patient too.

Such visits to the hospital are becoming more common lifesaving procedures today to unblock arteries clogged with plaque which reduce blood flow. One physician 
said:
“I actually feel a little guilty when I have to use the femoral route,” Tremmel said. She performs almost all of her PCIs and angiography, a diagnostic technique using special dye and x-rays to look for heart disease, transradially. “
Transradial patients don’t require the nurse to pressure on the patient’s groin for about a half hour to help stop bleeding either and it’s a shorter distance to the heart and the patient is not required to lay on their back for 6 hours after the procedure and get a small bracelet type device and a bandage. Many cardiologists are already familiar with the femoral artery procedure and thus retraining may need to take place in many hospitals for the “wrist” procedure to become more common. Transradial Interventions have an entire department of their own at Stanford. BD
STANFORD, Calif.--(EON: Enhanced Online News)--You can have a percutaneous coronary intervention through your femoral artery or radial artery. Put another way, you can have a catheter stuck into your groin or your wrist. Not sure which you’d prefer?
“It’s a whole lot easier on the body”
Then consider Richard Francis, a local accountant and ex-Navy pilot, who had stents inserted through the radial artery in his wrist at Stanford Hospital & Clinics on July 15, two days before turning 67.
A coronary stent is a tiny mesh tube that helps open up blood vessels clogged with cholesterol, fat and other stuff that leads to heart disease. Stenting is usually preceded by angioplasty, which involves expanding a balloon inside the artery to crush the plaque. Sometimes angioplasty is used exclusively. In any case, procedures practically guarantee a night in a hospital bed if done the traditional way — through the femoral artery.
