Thematic Review

This thematic review focuses on recently proposed classification of stages in pronounced aortic stenosis based on the prevalence of extravalvular cardiac damage and its modified variant designed for asymptomatic patients. The review presents studies, which analyzed the predictive significance of the proposed classification. The use of this classification allows predicting the course of disease in patients with pronounced aortic stenosis in valve replacement. The classification is based on routinely used structural and functional echocardiographic signs with already proven predictive values with respect of adverse events in patients after aortic valve replacement. The review discusses limitations of the classification for pronounced aortic stenosis stages based on the prevalence of extravalvular cardiac damage.

Aortic stenosis is a very common disease. Current guidelines recommend intervention mainly in symptomatic patients; aortic valve replacement can be considered in asymptomatic patients under specific conditions, but the evidence supporting these indications is poor. Continuous advances in both surgical and percutaneous techniques have substantially decreased rates of perioperative complications and mortality; with this in mind, many authors suggest that earlier intervention in patients with severe aortic stenosis, when they are still asymptomatic, may be indicated. This paper summarises what is known about the natural history of severe aortic stenosis and the scientific evidence available about the optimal timing for aortic valve replacement.

Calcific aortic stenosis is a prevalent and worrisome healthcare problem. The therapeutic approach in asymptomatic aortic stenosis is not well established. We argue that the natural history of this disease is based on old incomplete studies with many limitations. Likewise, studies suggesting that replacement, either surgical or percutaneous, improves prognosis in asymptomatic patients with severe aortic stenosis have important drawbacks and do not support this strategy as the treatment of choice. Despite the lack of evidence, some groups recommend early valve replacement in patients with severe asymptomatic aortic stenosis. There are five ongoing randomised trials which will shed light on this topic. Our conclusion is that unless a randomised study changes the evidence, valve replacement cannot be recommended in asymptomatic patients with severe aortic stenosis.

Introduction: In asymptomatic patients with severe aortic stenosis (SAS), left ventricular (LV) ejection fraction (EF) <50% is generally considered to be the threshold for referral for aortic valve replacement (AVR). Hypothesis: We investigated the importance of LVEF on long-term outcome after AVR in symptomatic and asymptomatic SAS patients and studied whether LVEF < 50% is the optimal threshold for referral for AVR. Methods and Results: We retrospectively identified 2017 patients with SAS (aortic valve area (AVA)<1cm2, mean aortic valve gradient ≥40 mm Hg, or indexed AVA <0.6 cm2/m2) who underwent surgical AVR from January 1995 to June 2009 at our institution. Patients were divided into 4 groups depending on preoperative LVEF (<50% in 300 (15%) patients, 50-59% in 331 (17%), 60-69% in 908 (45%), and ≥70% in 478 (24%)). The primary end-point was all-cause mortality. During follow-up of 5.3±4.4 years, 1056 (52%) died. Five-year mortality rate increased with decreasing LVEF (41% (n=106), LVEF<50%); 35% (n=98), LVEF 50-59%; 26% (n=192), LVEF 60-69%; 22% (n=90), LVEF≥70%, p<0.0001). Compared to patients with LVEF≥60%, patients with LVEF 50-59% had increased mortality (HR 1.58, p<0.001), with a similar risk increase in both symptomatic (HR=1.56, p<0.001) and asymptomatic patients (HR 1.58, p=0.006, Figure). In a Cox regression analysis corrected for standard risk factors, LV mass index, AVA, and stroke volume index, LVEF was predictive of all-cause mortality (HR=0.89 per 10%, p<0.001). When this multivariable analysis was repeated in the subset of 1333 patients with no history of coronary artery disease, LVEF was still associated with all-cause mortality (HR=0.90 per 10%, p=0.009). Conclusion: In patients with SAS undergoing AVR, patients with LVEF 50-59% have also increased mortality compared to patients with LVEF>60%, suggesting that a different LVEF threshold should be used when referring for AVR.

Staging Classification

Severe aortic stenosis (AS) causes chronic pressure overload of the left ventricle (LV), resulting in progressive cardiac change that can extend beyond the LV. A new AS staging classification has been recently proposed encompassing the extent of cardiac changes in AS. The AS staging classification has important prognostic implications for clinical outcomes after aortic valve replacement. This article introduces the AS staging system and demonstrates the association of the extent of cardiac change with outcomes after transcatheter aortic valve replacement.

Contemporary Outcomes after Surgery and Medical Treatment in Patients with Severe Aortic Stenosis (CURRENT AS) registry was a large Japanese multicentre retrospective registry of consecutive patients with severe aortic stenosis (AS) before introduction of transcatheter aortic valve implantation. We sought to overview the data from the CURRENT AS registry to discuss the three major contemporary issues related to clinical practice in patients with severe AS: (1) under-referral/underuse of surgical aortic valve replacement (SAVR) in symptomatic patients with severe AS, (2) management of asymptomatic patients with severe AS and (3) management of patients with low-gradient severe aortic stenosis (LG-AS). First, despite the dismal prognosis of symptomatic patients with severe AS, SAVR, including those performed during follow-up, was reported to be underused. In the CURRENT AS registry, overall 53% of symptomatic patients underwent aortic valve replacement (AVR) during follow-up. Second, we reported that compared with conservative strategy, initial AVR strategy was associated with lower risk of all-cause death and heart failure hospitalisation in asymptomatic patients with severe AS. Although current recommendations for AVR are mainly dependent on the patient symptoms, some patients may not complain of any symptom because of their sedentary lifestyle. We also reported several important objective factors associated with worse clinical outcomes in asymptomatic patients with severe AS for risk stratification. Finally, initial AVR strategy was associated with better long-term clinical outcomes than conservative strategy in both patients with high-gradient AS and patients with LG-AS. The favourable effect of initial AVR strategy was also seen in patients with LG-AS with left ventricular ejection fraction of ≥50%.
