After failure of the drug balloon, changes in the vessel can be observed dynamically by arteriography, and drug ballooning or stenting can be performed again if necessary.
Drug balloon dilatation therapy is to release the drug into the vessel wall, the drug’s action time is limited, after reaching a certain time will be ineffective. If there is no significant stenosis, continue to give aspirin, atorvastatin and other drugs.
Some patients may develop severe stenosis after drug balloon failure, and the severity of the condition can be assessed by coronary angiography. If indicated, drug balloon therapy can be repeated, and some patients can be treated with stent implantation.
If there is any discomfort, seek medical attention and follow the doctor’s instructions for the specific treatment plan.
