Has anyone here, or anyone you know ever had a TMR, or Transmyocardial Revascularization? It's not that common of a procedure, and I personally have never heard anyone mention this.
It is a procedure that is used at times for people who have severe angina or in very ill patients who aren't candidates for bypass surgery or angioplasty.
Some of the potential candidates for this procedure may also include;
"people who are high-risk candidates for a second bypass or angioplasty.
people whose blockages are too diffuse to be treated with bypass alone.
some patients with heart transplants who develop atherosclerosis (ath"er-o-skleh-RO'sis) after their transplant."
