Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with aortic regurgitation (a leaky aortic heart valve) or aortic stenosis (a narrowed aortic valve), and healthy adults. A device records the pulse in the finger without needles or cuts.
- Age
- 18 to 80 years
- Sex
- All sexes
- Disease stage
- Patients need a doctor's diagnosis of aortic regurgitation or aortic stenosis. Healthy volunteers must have no history of heart or blood vessel disease.
- Earlier treatment
- People who had heart surgery or a heart procedure in the last 6 months cannot join.
Main reasons for not taking part
- Heart surgery or a heart procedure in the last 6 months
- Hand problems that limit finger movement, such as arthritis
- Being pregnant or breastfeeding
- Taking part in other studies that affect the pulse wave
- Not able to understand or follow the study steps

About the trial
What the trial wants to find out
The goal of this observational study is to learn whether noninvasive real-time arterial waveform monitoring can be used to assess cardiovascular diseases in adults. The main question it aims to answer is:
Read full original descriptionShow less
Can photoacoustic imaging accurately capture arterial waveforms from patients' fingers? Can features extracted from the arterial waveforms reflect the type and severity of cardiovascular diseases? Participants will be asked to place their fingers into the imaging device, where their finger arterial pulse information will be noninvasively recorded.
The 3 groups in the trial
- Healthy Subjects
Healthy adult volunteers with no known cardiovascular disease will undergo noninvasive arterial waveform acquisition using the photoacoustic imaging device. No intervention is applied; data collection provides baseline waveform features for comparison with AR and AS patients.
- Aortic Regurgitation (AR) Patients
Participants diagnosed with aortic regurgitation (AR) will undergo noninvasive arterial waveform acquisition using a photoacoustic imaging device. No intervention is applied; data collection focuses on capturing finger arterial pulse waveforms to assess features associated with AR.
- Aortic Stenosis (AS) Patients
Participants diagnosed with aortic stenosis (AS) will undergo noninvasive arterial waveform acquisition using the same photoacoustic imaging device. No intervention is applied; data collection focuses on capturing finger arterial pulse waveforms to assess features associated with AS.
Questions to ask the study team
- How often do I need to come in, and for how long each time?
- Are travel costs paid?
- Can I keep my own doctor?
- What happens if I want to stop?
