Right-Sided Heart Failure and Extracorporeal Life Support in Patients Undergoing Pericardiectomy for Constrictive Pericarditis: A Risk Factor Analysis for Adverse Outcome.
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. ⋯ Binary logistic regression identified pleural effusion (OR = 16.2, 95% CI = 1.4-191.5), moderate/severe TI (OR = 28.8, 95% CI = 2.7-306.8) and low cardiac index (OR = 25.3, 95% CI = 2.0-315.6) as preoperative independent risk factors for early mortality, whereas elevated GGT (OR = 28.3, 95% CI = 2.4-329.2) and decreased protein (OR = 24.7, 95% CI = 1.8-343.7) could predict right ventricular failure with the need for ECMO. 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.

Prevalence, Diagnosis, Perioperative Monitoring and Treatment of Right Ventricular Dysfunction and/or Pulmonary Arterial Hypertension in Cardiac Surgical Patients in Germany-A Postal Survey.
Background Sparse data are available on the prevalence of right ventricular dysfunction and/or pulmonary arterial hypertension in patients scheduled for cardiac surgery in Germany as well as on the intensity and modalities used for diagnosis, perioperative monitoring, and treatment of these comorbidities. Methods A postal survey including questions on the prevalence of preoperative right ventricular dysfunction and/or pulmonary arterial hypertension in patients undergoing cardiac surgery in 2009 was sent to 81 German heart centers. Total 47 of 81 (58%) heart centers returned the questionnaires. ⋯ Conclusion The prevalence of preoperative right heart dysfunction and pulmonary arterial hypertension in cardiac surgical patients in Germany seems to be substantial. However, in more than 50% of the patients, no preoperative data on right ventricular function and pulmonary arterial pressure are available. This may lead to underestimation of perioperative risk and inappropriate management of this high-risk population.
