Background The mortality risk attributable to moderate aortic stenosis (AS) remains incompletely characterized and has historically been underestimated. We aim to evaluate the association between moderate AS and all‐cause death, comparing it with no/mild AS (in a general referral population and in patients with heart failure with reduced ejection fraction). Methods and Results A systematic review and pooled meta‐analysis of Kaplan–Meier‐derived reconstructed time‐to‐event data of studies published by June 2023 was conducted to evaluate survival outcomes among patients with moderate AS in comparison with individuals with no/mild AS. Ten studies were included, encompassing a total of 409 680 patients (11 527 with moderate AS and 398 153 with no/mild AS). In the overall population, the 15‐year overall survival rate was 23.3% (95% CI, 19.1%–28.3%) in patients with moderate AS and 58.9% (95% CI, 58.1%–59.7%) in patients with no/mild aortic stenosis (hazard ratio [HR], 2.55 [95% CI, 2.46–2.64]; P <0.001). In patients with heart failure with reduced ejection fraction, the 10‐year overall survival rate was 15.5% (95% CI, 10.0%–24.0%) in patients with moderate AS and 37.3% (95% CI, 36.2%–38.5%) in patients with no/mild AS (HR, 1.83 [95% CI, 1.69–2.0]; P <0.001). In both populations (overall and heart failure with reduced ejection fraction), these differences correspond to significant lifetime loss associated with moderate AS during follow‐up (4.4 years, P <0.001; and 1.9 years, P <0.001, respectively). A consistent pattern of elevated mortality rate associated with moderate AS in sensitivity analyses of matched studies was observed. Conclusions Moderate AS was associated with higher risk of death and lifetime loss compared with patients with no/mild AS.

Abstract In response to the coronavirus disease 2019 (COVID-19) pandemic, the Cardio-Oncology and Imaging Councils of the American College of Cardiology offers recommendations to clinicians regarding the cardiovascular care of cardio-oncology patients in this expert consensus statement. Cardio-oncology patients—individuals with an active or prior cancer history and with or at risk of cardiovascular disease—are a rapidly growing population who are at increased risk of infection, and experiencing severe and/or lethal complications by COVID-19. Recommendations for optimizing screening and monitoring visits to detect cardiac dysfunction are discussed. In addition, judicious use of multimodality imaging and biomarkers are proposed to identify myocardial, valvular, vascular, and pericardial involvement in cancer patients. The difficulties of diagnosing the etiology of cardiovascular complications in patients with cancer and COVID-19 are outlined, along with weighing the advantages against risks of exposure, with the modification of existing cardiovascular treatments and cardiotoxicity surveillance in patients with cancer during the COVID-19 pandemic.
