What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new, less invasive way to perform coronary artery bypass grafting (CABG) that avoids touching the aorta. The new method uses a small incision in the left chest, while the standard approach opens the chest fully. Researchers will compare how well the bypass grafts stay open and how safe each procedure is in 260 people with coronary artery disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
No-touch technique for the ascending aorta during minimally invasive coronary artery bypass surgery
What this could lead to
If successful, this technique could offer a safer, less invasive alternative to traditional open-chest bypass surgery, potentially reducing complications and improving recovery.
What could go wrong
This is a single-center study with 260 participants, so results may not apply to all patients. The new technique may not be as effective as standard surgery, and there are risks common to any heart surgery, such as infection or bleeding.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with angina pectoris who experience functional limitations in daily life and work despite conservative medical treatment and who require coronary artery bypass grafting surgery, as confirmed by coronary angiography, are eligible for enrollment. * Patients with calcification of the ascending aorta, as confirmed by CT, who are not suitable for sidewall clamping are also eligible for enrollment. Exclusion Criteria: * The patient presents with an old, large myocardial infarction with no surviving myocardium, as evidenced by both isotope and echocardiographic imaging. This is a group of patients who are prone to complications, including significant cardiac enlargement, a cardiothoracic ratio greater than 0.75, an ejection fraction (EF) less than 30%, a left ventricular diameter (LVDd) greater than 70mm, the presence of a left ventricular ventricular wall tumor, or severe arrhythmia. Intraoperative hemodynamic instability; * Valve surgery or other intracardiac surgery at the same time; * Patients expected to undergo extracorporeal circulation surgery; * Poor myocardial infarction conditions, extensive lesions, distal or full diffuse stenosis, or lumen diameter less than or severe calcification that cannot be anastomosed. * Previous open heart surgery. * Patients with preoperative hemodynamic instability requiring emergency surgery. * Other conditions include terminal malignant tumors, uncontrollable infections, bleeding, persistent progressive degenerative systemic diseases, severe brain injuries, and multiple organ failure. Additionally, other significant organ function serious impairments, such as severe liver function impairment, severe heart failure, or cardiogenic shock, may also be considered contraindications. Inability to tolerate surgery may also be considered a contraindication. * The participant declines to take part in this study.
