Tab Title Description
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.

About this study
Our overall goal is to determine whether the AVR improves SDB where present and sleep profiles (including sleepiness symptoms, quality of life and hypoxia).
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Adults: >18 years
Patients with severe AS (valve area ≤1 cm2, mean gradient ≥40 mmHg, or peak velocity ≥4.0 m/s), or clinically severe aortic stenosis in the context of low-gradient and/or low ejection fraction.
Patients who have other significant valvular disease (warranting surgery or intervention)
Patients who have known SDB and have received treatment (current or active). Patients with a known diagnosis of SDB but have never received treatment are eligible.
Patients who are unable to consent
Children/adolescents under age 18 years
Pregnancy (women known to be pregnant)
