Preventing Postpericardiotomy Syndrome: Current Evidence and Future Directions

Area of Science:

• Cardiology
• Thoracic Surgery
• Inflammation Research

Background:

• Postpericardiotomy syndrome (PPS) is a frequent inflammatory complication after cardiac surgery, leading to significant morbidity and mortality.
• Current prevention strategies for PPS are often empirical, lacking standardization and mechanism-based approaches.

Purpose of the Study:

• To critically synthesize existing preventive strategies for PPS, including pharmacologic, surgical, and biomarker-based approaches.
• To address deficiencies in current PPS prevention and explore emerging risk stratification tools.

Main Methods:

• Literature review of randomized controlled trials, meta-analyses, cohort studies, and mechanistic research.
• Evaluation of pharmacologic interventions, surgical modalities, and biomarker-based preventive strategies.

Main Results:

• Colchicine is the most evidence-based pharmacologic intervention, consistently reducing PPS incidence.
• Surgical techniques like pericardial closure and posterior pericardiotomy reduce complications without hemodynamic compromise.
• Biomarkers (neutrophil-to-lymphocyte ratio, CRP, cytokines) aid in identifying high-risk patients for personalized prevention.

Conclusions:

• A combination of evidence-based pharmacologic prophylaxis (colchicine), innovative surgical techniques, and biomarker-guided risk stratification offers a pathway to reduce PPS incidence and burden.
• Personalized prevention strategies are emerging as crucial for managing PPS in contemporary cardiac surgery.
