Risk factors for mortality after pericardiectomy for chronic constrictive pericarditis in a large single-centre cohort

Surgery for CP is associated with a significant risk based on the poor preoperative patient status. Whenever justified, partial over radical pericardiectomy should be preferred and TVR should be indicated liberally. Reduced LVEF and right ventricular dilatation were independent predictors for early mortality, whereas CAD, chronic obstructive pulmonary disease and renal insufficiency were risk factors for late mortality. Thus, an optimal timing for surgery on CP remains crucial to avoid secondary morbidity with an even worse natural prognosis.
