Plain-language summary
This study is testing a digital stethoscope called the Keikku electronic stethoscope. Doctors use stethoscopes to listen to the heart, and this new device records heart sounds using a smartphone app. The purpose of the study is to check how well this new device works and whether it is safe to use.
The study will include 149 participants of all ages (from birth to 99 years), who are undergoing routine (non-urgent) heart checks. After giving consent, each participant will have their heart sounds listened to twice: once with the Keikku electronic stethoscope and once with a regular stethoscope. Two different doctors will do the listening, and they won't share information with each other. The doctors will record whether they hear a heart murmur and how clear the sounds were.
The study will compare the findings from the new device to those from the regular stethoscope. Researchers will also check for any device problems or side effects. The study takes place at a single site in Peru and will take about one day for each participant.
The goal is to find out if the Keikku electronic stethoscope is accurate and safe for doctors to use in real medical settings.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
