The prognostic value of lung ultrasound in aortic stenosis

Abstract Funding Acknowledgements Type of funding sources: None. Background Aortic stenosis (AS) is a progressive disease and once symptomatic heart failure (HF) develops associated with poor prognosis. The degree the pathophysiological structural changes in AS are survival. Pulmonary congestion an almost universal finding patients HF. Lung ultrasound (LUS) evaluation B-lines has been proposed as simple, non-invasive tool to assess pulmonary congestion. Aim To LUS define prognostic value B-lines. Methods 84 consecutive (43 women, mean age 74 ± 9 years) moderate or severe were enrolled. Exclusion criteria follows: aortic regurgitation, mitral cardiomyopathies, disease, renal failure. At baseline, all underwent comprehensive echocardiography examination according 28 scanning-site assessment. Patients followed-up after enrollment establish LUS. A composite endpoint was considered, including: valve replacement due deterioration patient condition progression from severe, death (any cause), hospitalization acute chronic which required hospitalization. Results We found number (total ≥30) 31% patients. correlated estimated artery systolic pressure (p < 0,005, r= 0,52) increased along NYHA class 0,001) Figure 1. ≥30 had more events during 13,4 6 months follow-up 0,001, Log-rank: 10,7; 2).
