Pericardiectomy with routine cardiopulmonary bypass: a multicenter, randomized controlled trial

Area of Science:

• Cardiology
• Thoracic Surgery

Background:

• Constrictive pericarditis involves pericardial thickening, impairing diastolic filling and cardiac output.
• Chronic inflammation leads to calcification, fibrosis, and eventual heart failure.

Purpose of the Study:

• To compare the prognosis of pericardial resection with and without extracorporeal circulation.
• To evaluate the efficacy of different surgical approaches for constrictive pericarditis.

Main Methods:

• Multicenter, randomized controlled trial.
• 436 participants assigned to extracorporeal circulation or non-extracorporeal circulation pericardial resection.
• Evaluator-blinded, parallel group design.

Main Results:

• Incomplete pericardial detachment correlates with low cardiac output syndrome.
• Key factors for recovery include complete resection and relief of ventricular compression.

Conclusions:

• Surgical technique significantly impacts outcomes in constrictive pericarditis.
• Optimizing pericardial resection is crucial for preventing postoperative complications and improving cardiac function.
