The most frequently affected valves were aortic (17.3%) and mitral (11.2%) valves, with thickening (19.5%) and regurgitation (15.9%) as the leading lesion types. aPLs positive patients with SLE had higher rates of HVD (35.1% vs 24.0%, p=0.010), including valve thickening (25.3% vs 16.9%, p=0.028), regurgitation (24.7% vs 12.1%, p&lt;0.001), vegetations (9.1% vs 0.8%, p&lt;0.001) and stenosis (1.9% vs 0.0%, p=0.008). Anticardiolipin-IgG was associated with HVD (OR=2.484, p=0.003), mitral lesions (OR=4.156, p&lt;0.001), valve thickening (OR=2.255, p=0.011) and regurgitation (OR=2.121, p=0.014). Anti-\u03b22 glycoprotein I-IgG showed similar associations and was also linked to valve stenosis (OR=11.209, p=0.022). Lupus anticoagulant (LA) was associated with valve vegetations (OR=8.659, p&lt;0.001) and interventional\/surgical indications (OR=6.868, p=0.005).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>aPLs, especially IgG isotype and LA, are independently associated with diverse HVD in SLE.
