Surgical treatment of constrictive pericarditis at a single center: 10 years of experience

Abstract

Background: Constrictive pericarditis (CP) is a pericardial disease characterized by the pericardium becoming calcified or fibrotic as a result of chronic inflammation, which impairs diastolic filling by compressing the cardiac chambers. Pericardiectomy is a promising surgical option for treating CP. In this study, we reviewed over 10 years of preoperative, perioperative, and short-term postoperative follow-ups of patients who underwent pericardiectomy for constrictive pericarditis at our clinic.

Methods: Between January 2012 and May 2022, 44 patients were diagnosed with constrictive pericarditis. Twenty-six patients underwent pericardiectomy for CP. Median sternotomy is the surgical approach of choice because it provides easy access for complete pericardiectomy.

Results: The patient median age was 56 (min: 32, max: 71), and 22 out of 26 patients (84.6%) were male. Twenty-one patients (80.8%) complained of dyspnea, which was the most common reason for admission. Twenty-four patients (92.3%) were scheduled for elective surgery. Cardiopulmonary bypass (CPB) was used during the procedure in six patients (23%). The duration of intensive care stay was two days (min: 1, max: 11), and the total hospitalization was six days (min: 4, max: 21). No in-hospital mortality was observed.

Conclusion: The median sternotomy approach provides a critical advantage in terms of performing a complete pericardiectomy. Although CP is a chronic condition, early diagnosis and planning of pericardiectomy before irreversible deterioration of cardiac function leads to a notable reduction in mortality and morbidity.
