Background: Although current guidelines generally recommend watchful waiting strategy for patients with asymptomatic severe aortic stenosis (AS) until symptoms develop, the optimal timing of surgical intervention remains controversial. Objective: This study aimed to compare the outcomes of early surgery vs. conservative strategy for patients with asymptomatic severe AS. Methods: MEDLINE and EMBASE were searched through February, 2020 to identify clinical trials that investigatedearly surgery and conservative strategy for patients with asymptomatic severe AS. From each study, we extracted the hazard ratio (HR) of all-cause mortality and cardiovascular mortality. Subgroup analyses were conducted by dividing into severe AS (peak aortic jet velocity [Vmax] ≥4.0 m/s, mean aortic pressure gradient [PG] ≥40 mmHg, or aortic valve area [AVA] ≤1.0 cm 2 ) and very severe AS (Vmax ≥4.5 m/s, mean PG ≥50 mmHg, or AVA ≤0.75 cm 2 ) groups. Results: 1 randomized controlled, 7 observational trials were identified. Pooled analyses demonstrated that all-cause mortality and cardiovascular mortality for early surgery were significantly lower compared to conservative strategy (HR [95% Confidence Interval [CI]] =0.49 [0.36-0.68]; P <0.0001, HR [95% CI] =0.42 [0.22-0.82]; P =0.01, respectively). Subgroup analyses showed significant reduction for early surgery in all-cause mortality (severe AS: HR [95% CI] =0.52 [0.35-0.78]; P =0.001, very severe AS: HR [95% CI] =0.38 [0.17-0.85]; P =0.02). Conclusions: We demonstrated that early surgery was associated with significant reduction in all-cause and cardiovascular mortality in patients with severe AS. Further randomized trials are warranted to confirm our findings.

In patients with aortic stenosis (AS), a novel staging classification of extra-valvular left and right heart damage with prognostic relevance was introduced in 2017. The aim of the study was to evaluate the biomarkers of cardiovascular tissue remodelling in relation to this novel staging classification. Patients were categorized according to the novel staging classification into stages 0 to 4. The levels of matrix metalloproteinase 9 (MMP-9), tissue inhibitor of metalloproteinases 1 (TIMP-1), B and C domain containing tenascin-C (B+ Tn-C, C+ Tn-C), the ED-A and ED-B domain containing fibronectin (ED-A+ Fn, ED-B+ Fn), endothelin 1 (ET-1) and neutrophil gelatinase-associated lipocalin (NGAL) were determined in serum by ELISA. There were significantly decreased serum levels of MMP-9 and increased levels of B+ Tn-C and C+ Tn-C when comparing stages 0 and 1 with stage 2, with no further dynamics in stages 3 and 4. In contrast, for TIMP-1, C+ Tn-C, ED-A+ Fn, ET-1 and NGAL, significantly increased serum levels could be detected in stages 3 and 4 compared to both stages 0 and 1 and stage 2. ED-A+ Fn and ET-1 could be identified as independent predictors of the presence of stage 3 and/or 4. To the best of our knowledge, this is the first study identifying novel serum biomarkers differentially reflecting the patterns of left and right heart extra-valvular damage in patients suffering from AS. Our findings might indicate a more precise initial diagnosis and risk stratification.

Abstract Aims Cardiac damage in severe aortic stenosis (AS) can be classified according to a recently proposed staging classification. The present study investigated the incremental prognostic value of left ventricular (LV) global longitudinal strain (GLS) over stages of cardiac damage in patients with severe AS. Methods and results From an ongoing registry, a total of 616 severe symptomatic AS patients with available LV GLS by speckle tracking echocardiography were selected and retrospectively analysed. Patients were categorized according to cardiac damage on echocardiography: Stage 0 (no damage), Stage 1 (LV damage), Stage 2 (mitral valve or left atrial damage), Stage 3 (tricuspid valve or pulmonary artery vasculature damage), or Stage 4 (right ventricular damage). LV GLS was divided by quintiles and assigned to the different stages. The endpoint was all-cause mortality. Over a median follow-up of 44 [24–89] months, 234 (38%) patients died. LV GLS was associated with all-cause mortality independent of stage of cardiac damage. After incorporation of LV GLS by quintiles into the staging classification, Stages 2–4 were independently associated with outcome. LV GLS showed incremental prognostic value over clinical characteristics and stages of cardiac damage. Conclusion In this large single-centre cohort of severe AS patients, incorporation of LV GLS by quintiles in a novel proposed staging classification resulted in refinement of risk stratification by identifying patients with more advanced cardiac damage. LV GLS was shown to provide incremental prognostic value over the originally proposed staging classification.
