Trial
PALACS
Posterior left pericardiotomy significantly reduced the incidence of post-operative atrial fibrillation (AF) after cardiac surgery and appeared safe in the PALACS trial [1]. Post-operative AF is the most common complication of cardiac surgery, with an incidence of 20–40%, depending on the performed surgery [2]. The incidence of post-operative pericardial effusion is also common, with an incidence of 60–70% [3]. Dr Mario Gaudino (Weill Cornell Medical Center, NY, USA), first author of the PALACS trial (NCT02875405), argued there is evidence that post-operative pericardial effusion is associated with post-operative AF [1,4]. The PALACS study hypothesised that a 4 to 5 cm incision in the posterior pericardium, connected to the left pleural cavity, allows for drainage and, thus, reduces post-operative AF. Patients (n=420) undergoing cardiac surgery (i.e. coronar...
