Application of coronary angioplasty to the septal perforator arteries.

Significant coronary artery disease affecting the septal perforator arteries can cause anginal pain, rhythm disturbances, or septal infarction. However, since these vessels are usually inaccessible to coronary bypass surgery, there is a tendency among angiographers and angioplasters to overlook lesions of the septal perforator arteries. Our experience suggests that if medical treatment is not sufficient to treat clinical manifestations resulting from septal perforator disease, then coronary angioplasty can be considered a therapeutic alternative for revascularization. We herein present 11 patients who underwent coronary angioplasty of a major septal artery and discuss angiographic and technical aspects of the procedure.
