Brief Summary
aims to compare the efficacy of the posterior pericardial window versus retro-cardiac drain in preventing postoperative atrial fibrillation and pericardial complications following CABG, while assessing their impact on hospital and ICU stay, pericardial effusions, re exploration for bleeding, post-operative blood transfusions, and mortality.

Outcome Measures
Primary Outcomes (1)
Incidence of postoperative atrial fibrillation and pericardial complications
Postoperative atrial fibrillation will be detected by continuous ECG monitoring during hospitalization. Pericardial complications, including early and late pericardial effusion, cardiac tamponade, and pleural effusion, will be assessed using echocardiography. The outcome will be reported as the number and percentage of participants experiencing any of these events.
During hospitalization and up to 3 months after surgery
Secondary Outcomes (1)
Postoperative clinical outcomes (ICU stay, hospital stay, revision surgery, and in-hospital mortality)
From surgery until hospital discharge (up to 30 days)
Study Arms (2)
Group 1: 61 patients undergoing CABG will have a posterior pericardial window created for drainage.
Based on determining the main outcome variable, the estimated minimum required sample size is 122 patients (61 patients in each group). * Group I (Posterior Pericardial Window group): 61 patients undergoing CABG will have a posterior pericardial window created for drainage. * Group II (Retro-cardiac Drain group): 61 patients undergoing CABG will receive a retro-cardiac drain for pericardial drainage.
Group 2 : 61 patients undergoing CABG will receive a retro-cardiac drain for pericardial drainage.

Eligibility Criteria
The study population will include adult patients scheduled to undergo elective, first-time, isolated coronary artery bypass grafting (CABG) surgery via median sternotomy. Eligible participants will be hemodynamically stable and able to provide informed consent prior to enrollment. Patients will be randomized intraoperatively to receive either a posterior pericardial window or a retro-cardiac drain for postoperative management.
You may qualify if:
- Adult patients (aged 18 and above) scheduled for elective, first-time coronary artery bypass grafting (CABG).
- Patients with preserved left ventricular function (ejection fraction ≥ 35%).
- Ability to provide informed consent and comply with follow-up protocols.
- No prior history of atrial fibrillation or other significant arrhythmias.
You may not qualify if:
- Patients undergoing combined cardiac procedures (e.g., valve repair or replacement).
- Emergency CABG cases or re-operations.
- Known bleeding disorders or ongoing anticoagulation therapy that cannot be paused.
- Severe pericardial adhesions or anatomical abnormalities preventing safe creation of a posterior pericardial window.
- Chronic pulmonary disease or pleural pathology that may interfere with drainage assessment.
- Patients with active infections or systemic inflammatory conditions.
