The Minimally Invasive Coronary Surgery Compared to STernotomy Coronary Artery Bypass Grafting Trial

Plain-language summary
MICS CABG (Minimally invasive coronary surgery), where coronary artery bypass grafting (CABG) is completed through a small incision over the left chest, has evolved to become a safe and less invasive alternative to conventional sternotomy CABG. Several observational studies have suggested significantly shorter time to return to physical activity for MICS CABG patients compared to sternotomy CABG patients. A randomized study is warranted to validate these findings, provide higher level of evidence, and potentially lead to changes in practice. The MIST Trial is a multi-centre, prospective, open label, randomized control trial comparing quality of life and recovery in the early post-operative period, between patients undergoing MICS CABG versus patients undergoing sternotomy CABG. Patients referred for isolated CABG for multi-vessel coronary artery disease and deemed technically suitable for sternotomy CABG as well as for MICS CABG are considered for enrollment into the trial. Quality of life questionnaires (The SF-36, Seattle Angina Questionnaire and EQ-5D-5L) will be used to assess the quality of life and recovery in patients undergoing sternotomy CABG or MICS CABG at 1 month, 3 months, 6 months and 12 months follow up.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 18 years of age or older
* Angiographically-confirmed multi-vessel coronary artery disease lesions with \>=70% in at least 2 major epicardial vessels in 2 or more coronary artery territories (left anterior descending (LAD), circumflex (CX) and right coronary artery (RCA)) OR lesions \>=50% in the left main (LM)
* Patients who, in the opinion of the investigator, are amenable for coronary surgery through either median sternotomy or minimally-invasive approach.
* Patients who are willing and able to comply with all follow-up study visits.
Exclusion Criteria:
* \<18 years of age
* concomitant cardiac procedure with CABG (e.g. valve repair or replacement)
* Previous cardiac surgery, mediastinal irradiation, or significant trauma to the chest
* Contra-indications for MICS CABG, including: severe pectus excavatum; severe pulmonary disease; hemodynamically significant left subclavian stenosis; morbid obesity; severe left ventricular (LV) dysfunction; no adequate PDA or marginal branch target; absence of femoral pulse bilaterally.
* Contraindications for conventional CABG via sternotomy
* Concomitant life-threatening disease likely to limit life expectancy to \<2 years
* Emergency CABG with hemodynamic compromise
* Inability to provide informed consent.
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.
