Comparison of Post-operation Cardiopulmonary Capacity of Patients Underwent Conventional and Robot-assisted Coronary Artery Bypass Graft and Valve Replacement Surgery

Taiwan80 participantsStarted 2025-11-01

Plain-language summary

Robotic surgery is one of the most popular minimally invasive procedures for patients with coronary artery disease or valvular diseases. Studies have shown that, as compared to conventional sternotomy, patients underwent robot-assisted bypass grafting or valvuloplasty had less post-operation pain, blood transfusion volume during operation, re-operation rate, post-operation stroke rate and length of hospitalization. However, most studies focused on the comparison of complications of different procedures, and the investigation of cardiopulmonary function recovery is still lacking. Thus our study is to compare the functional outcomes between patients that undergo different surgical procedures.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * patient who undergo surgery for coronary artery bypass graft or valvular replacement. Exclusion Criteria: * pregnant * patients who receive more than one type of surgery * severe complications after surgery (ex. respiratory failure, stroke) and stayed in hospital for more than 2 weeks. * cannot perform the cardiopulmonary exercise testing * other contraindications for cardiopulmonary exercise testing

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
