Summary

This study tests a special balloon coated with a drug (paclitaxel) and natural ingredients (shellac and vitamin E) to treat narrowed small heart arteries. About 3000 adults with new blockages in small arteries will receive this balloon treatment during a standard procedure. The goal is to see if it safely keeps arteries open and reduces the risk of heart attacks or the need for repeat procedures.
