Fixed subaortic stenosis - rarecomplication of ankylosing spondyloarthritis

Abstract

Spondyloarthritis (SA) is a well known systemic chronic inflammatory disease involving spine, sacroileac and peripherial joints with extra-articular manifistations. Predominant connective tissue inflamation reflects the typical characters as enthesitis and aortitis, complicated by aortic insufficiency. Authors presents the case of high activity HLA-B27 positive SA young woman, that was complicated at debut with aortic ridge, caused uncommon severe left ventricular outflow fixed obstruction. Pecularities of aortic root structure and it’s involvement in SA, also as dynamic of aortic ridge growth by serial echocardiographic investigations are discussed.
