Spontaneous right coronary artery dissection possibly associated with clonidine transdermal patch.

We report on a 44-year-old female who developed spontaneous right coronary artery dissection associated with the use of a clonidine transdermal patch. The lesion was successfully treated with percutaneous coronary intervention with placement of three bare metal stents. The patient had an uneventful recovery. To our knowledge, this is the first reported case of spontaneous coronary artery dissection associated with clonidine effect.
