Surgical procedure to prevent heart rhythm issues after cardiac surgery

Pericardiotomy in Cardiac Surgery Trial

Not applicable Interventional Population Health Research Institute · NCT06486636

This study is testing a surgical procedure to see if it can help prevent heart rhythm problems after heart surgery for patients who haven't had these issues before.

What this trial studies

The PRINCE trial is an international, multicentre, randomized controlled trial investigating the effectiveness of posterior left pericardiotomy in patients undergoing cardiac surgery who do not have a history of atrial fibrillation or flutter. This procedure aims to reduce the incidence of post-operative atrial fibrillation (POAF), which is associated with significant adverse outcomes such as mortality and heart failure. By allowing for prolonged drainage of pericardial fluid, the trial seeks to determine if this intervention can improve long-term clinical outcomes for patients after surgery. The study will follow participants over time to assess the impact of the procedure on hospital readmissions and overall health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older requiring surgical intervention on the proximal aorta, cardiac valves, or coronary arteries without a history of atrial fibrillation or flutter.

Not a fit: Patients with a history of atrial fibrillation or flutter, or those undergoing specific cardiac procedures not included in the study, may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this procedure could significantly reduce the occurrence of post-operative atrial fibrillation and improve long-term health outcomes for cardiac surgery patients.

How similar studies have performed: Previous research has shown promising results for posterior pericardiotomy in reducing post-operative atrial fibrillation, but this trial aims to provide high-quality evidence on its impact on long-term clinical outcomes.
