AI summary: who the study is looking for
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 who have had heart surgery and then develop a new irregular heartbeat (atrial fibrillation) within 7 days after the operation.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- New atrial fibrillation that starts within the first 7 days (168 hours) after cardiac surgery, in the hospital wards or intensive care at University Hospital Basel.
- Earlier treatment
- Must have had cardiac surgery. Must not have had left atrial ablation before, or amiodarone treatment within the last 3 months.
Main reasons for not taking part
- Atrial fibrillation or atrial flutter documented before the surgery
- Previous left atrial ablation or cardioembolic stroke
- Amiodarone treatment within the last 3 months
- Left ventricular ejection fraction below 40%
- Mechanical circulatory support around the surgery

- Original description
This study is to describe the exact location of NOAF-maintaining foci and rotors after cardiac surgery identified by mapping using the non-invasive phase mapping with CardioInsightTM - 3D Mapping technology (CardioInsightTM, Medtronic Switzerland, Tolochenaz, Switzerland) and a low-dose computed tomography scan of the chest.Read full original descriptionShow less
Non-invasive Evaluation of New-onset Atrial Fibrillation After Cardiac Surgery The Basel CardioInsightTM - 3D Mapping (BigMap) Study
This study is to describe the exact location of NOAF-maintaining foci and rotors after cardiac surgery identified by mapping using the non-invasive phase mapping with CardioInsightTM - 3D Mapping technology (CardioInsightTM, Medtronic Switzerland, Tolochenaz, Switzerland) and a low-dose computed tomography scan of the chest.
Inclusion: Cardiac surgery; Signed informed consent by patient or next of kin; Mapping inclusion criteria; NOAF within the first seven postoperative days (168 hours) after cardiac surgery developing on the cardiac surgery ward, intermediate care unit or the intensive care unit of the University Hospital Basel. ICU admission will be set as starting point for observation time; General Exclusion Criteria:; Preoperative conditions:; History of previous left atrial ablation; History of cardioembolic stroke; History of amiodarone treatment within three months; Any documented history of atrial fibrillation/atrial flutter before surgery; Left ventricular ejection fraction <40%; Patient included into other study with radiation exposure; Perioperative conditions; Perioperative mechanical circulatory support (e.g., intraaortic balloon pump; extracorporeal membrane oxygenation; left ventricular assist device (e.g. Impella, Abiomed Inc., Aachen, Germany); Mapping exclusion criteria; Heart rate ≥ 50 bpm AND contraindication to adenosine; Contraindications to adenosine:; Allergy/intolerance to adenosine; History of chronic obstructive pulmonary disease (COPD Gold IV)(28); History of asthma; History of Long-QT syndrome; Hemodynamically unstable patients (margin of discretion of the attending physician).
