In the presence of resistance to circumferential expansion of atherosclerotic plaques due to mechanical dilation high shear stresses between stiff plaques and normal vessel segments may occur and thus may result in coronary dissection. Limited data are available on the clinical and angiographic outcome of severe (type E, type F) coronary dissections. Herein, we report a case of type F dissection (causing total occlusion) of proximal right coronary artery during balloon angioplasty which healed spontaneously. In conclusion, although the type F dissection has worse prognosis due to complete cessation of distal vessel perfusion, the possibility of spontaneous healing should be kept in mind after unsuccessful intervention.
