PURPOSE: We studied the relationship of initial angiographic morphology in patients with aortic stenosis due to nonspecific aortitis and its relationship to immediate and later outcome following percutaneous transluminal angioplasty (PTA). METHODS: Correlation was performed in 10 successive patients by retrospective analysis. All had clinically inactive nonspecific aortitis and hemodynamically significant aortic stenosis resulting in hypertension or lower limb claudication. Five patients had discrete concentric stenosis; the other five had eccentric stenosis with diseased aortic segments adjacent to the stenosis. RESULTS: The five patients with concentric stenosis (Group I) had primarily successful and uncomplicated PTA with sustained improvement. The five patients (Group II) with eccentric stenosis had initial success in three patients and two initial treatment failures with one patient showing late improvement. Four of these patients developed large intimal flaps. One of these had an aneurysm during follow-up. Follow-up angiograms in five patients showed remodelling with further angiographic and clinical improvement. CONCLUSION: Eccentricity of the stenosis and diffuse aortic disease correlate unfavorably with immediate outcome of PTA but late improvement may still be seen.
