# Posterior Pericardiotomy and Its Impact on Cardiac Tamponade and Pericardial Effusion after Cardiac Surgery

## TL;DR

This study shows that a surgical technique called posterior pericardiotomy reduces complications like fluid buildup and heart compression after heart surgery.

## Contribution

The study introduces posterior pericardiotomy as a novel surgical technique to prevent postoperative pericardial effusion and tamponade.

## Key findings

- Posterior pericardiotomy significantly reduced early and late pericardial effusion rates.
- The technique also decreased the incidence of cardiac tamponade and postoperative atrial fibrillation.
- PP shortened hospital stays and reduced the need for surgical re-exploration.

## Abstract

Purpose: Pericardial effusion (PE), tamponade, and atrial fibrillation are challenging complications after cardiac surgeries. This prospective randomized study was conducted to evaluate the impact of posterior pericardiotomy (PP) in the prevention of PE and cardiac tamponed after adult cardiac surgery.

Methods: This single-center, prospective, randomized controlled trial included 330 patients undergoing open-heart surgery. They were randomly assigned to either a PP group or a control group.

Results: Of 703 screened patients, 330 were enrolled from January 2022 to June 2024 (mean age: 50.2 ± 14.7 years, 64.2% males). Compared to controls, the PP group had significantly lower early and late PE (19.4% vs. 44.8%, and 4.2% vs. 17%, respectively), tamponade (2.4% vs. 11.5%), and postoperative atrial fibrillation (10.3% vs. 19.4%). PP also significantly reduced the need for surgical re-exploration, duration of mechanical ventilation, and both intensive care unit and overall hospital stays (all P <0.05). Adjusted multivariate analysis confirmed the benefits of PP after correcting for baseline imbalances in left ventricular ejection fraction and operative time. No adverse events directly attributable to PP were noted.

Conclusions: PP is a simple, safe, and effective technique for reducing postoperative PE, and cardiac tamponade after cardiac surgery.
