In patients undergoing pericardiectomy for constrictive pericarditis, specific preoperative factors such as pleural effusion, tricuspid insufficiency, and low cardiac index strongly predict early mortality, while elevated GGT and decreased protein predict the need for postoperative ECMO.
Background Right ventricular failure is a life-threatening postoperative complication after pericardiectomy. We conducted a retrospective study with a special emphasis on right ventricular failure. Methods Between June 1997 and September 2011, 69 patients underwent surgical pericardiectomy at our center. Mean age was 59 ( ± 15.5) years, and 49 (71%) patients were male. Causes of constrictive pericarditis included idiopathic (52%, n = 36), tuberculosis (9%, n = 6), postcardiotomy (12%, n = 8), radiation (4%, n = 3), renal insufficiency (12%, n = 8), and autoimmune disease (12%, n = 8). Concomitant cardiac surgery was performed in 33 (48%) patients. Results In-hospital mortality rate was 14% (10/69 patients). Extracorporeal membrane oxygenation (ECMO) was necessary in 8 (12%) cases because of right (n = 7) or biventricular (n = 1) failure. Statistical analysis showed a significant correlation between early mortality and the following preoperative variables: postcardiotomy (p = 0.049), radiation (p = 0.009), pleural effusion (p = 0.012), ascites (p = 0.039), hepatic congestion (p = 0.023), absence of calcification on X-ray (p = 0.041), tricuspid valve insufficiency (TI, p p = 0.003). Diuretic usage (p = 0.044), peripheral edema (p = 0.050), low voltage (p = 0.027), dip-plateau sign (p = 0.027), elevated GGT (p p Conclusion We recommend nondelayed ECMO support in case of significant postoperative right-sided heart failure. High-risk patients might benefit from elective pre- or intraoperative ECMO implantation.
