@miriam98 - Myocardial laser revascularization sounds promising. I’ve heard a lot of good things about this procedure. The most important thing from my perspective is that it tends to be more long lasting.
The opened channels stay open for a much longer period of time. I think it’s better than stents because as you point out with stents sometimes the body treats them as foreign objects and tries to expel them through a process of new skin growth.
