Triangular posterior pericardiectomy (TPP) was evaluated for its impact on early and 12-month outcomes after coronary artery bypass grafting (CABG).
-
2
The study included 489 patients, with 347 undergoing standard surgery and 142 receiving TPP, analyzed from 2017 to 2023.
-
3
Four phenotypes were identified, with Phenotype 4 showing the highest TPP prevalence and the best postoperative outcomes, including no atrial fibrillation.
-
4
Patients with lower TPP prevalence exhibited higher CRP levels, greater drainage volumes, and increased incidence of postoperative atrial fibrillation.
-
5
TPP was associated with reduced inflammation, minimal pericardial effusion, and absence of early and late atrial fibrillation after CABG.
