percutaneousLithotripsy
Liver biopsy
Lung needle biopsy
Percutaneous transhepatic cholangiogram
Pericardiocentesis coronary artery intervention, also by an experienced operator. On the other hand, if heart function is low, and there is lots of myocardial scar, then the only option that you would have at that point would be to consider cardiac transplantation. There really isn't anything experimental that I am aware of that works on removing arterial plaque.
