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.

Forty-Two Years' Experience with Pulmonary Resections of Metastases from Colorectal Cancer.
Background Pulmonary metastasectomy is a commonly performed surgery in patients with controlled metastatic colorectal cancer (CRC). We reviewed our long-term single institution experience with lung resections for colorectal metastases to assess the factors influencing patient survival. Materials and Methods A cohort of 220 patients (138 men and 82 women; median age, 59 years) who underwent complete pulmonary metastasectomy for CRC with curative intent between 1972 and 2014 was retrospectively analyzed. ⋯ Multivariable Cox analysis demonstrated that stage IV CRC (p = 0.02) and multiple metastases (p = 0.0019) were statistically significant predictors of survival after the pulmonary metastasectomy. There was no significant difference in survival between patients with high versus low preoperative carcinoembryonic antigen serum level (p = 0.149), high versus low preoperative carbohydrate antigen 19-9 serum level (p = 0.291), and primary tumor location in rectum versus colon (p = 0.845). Conclusion Patients with unilateral metastasis and stages I to III primary tumor benefited most from pulmonary metastasectomy for CRC.

Review Meta AnalysisSurgical Repair of Moderate Ischemic Mitral Regurgitation-A Systematic Review and Meta-analysis.
Introduction Moderate mitral regurgitation (MR) of ischemic etiology has been associated with worse outcomes after coronary artery bypass grafting (CABG). Studies comparing concomitant mitral valve replacement/repair (MVR/Re) with CABG and standalone CABG have reported conflicting results. We performed a systematic review and meta-analysis of the published literature. ⋯ MD of change from baseline in left ventricular (LV) end-systolic dimension (MD: - 2.50, 95% CI: - 5.21 to - 0.21, p = 0.071) and LV ejection fraction (MD: 0.48, 95% CI: - 2.48 to 3.44, p = 0.750) were not significantly different between the groups. Incidence of moderate MR (MH RR: 3.24, 95% CI: 1.79-5.89, p < 0.001) was higher in the CABG only group. Conclusion Addition of MVR/Re to CABG in patients with moderate ischemic MR did not result in improvement in early or overall mortality, stroke risk, or intermediate markers of LV function when compared with CABG alone.

Plantar Sweating as an Indicator of Lower Risk of Compensatory Sweating after Thoracic Sympathectomy.
Background Hyperhidrosis is a dysfunction of the autonomic nervous system that results in regional excessive sweating, mostly in the hands, armpits, and feet. A permanent and effective treatment of hyperhidrosis can be achieved by interruption of the thoracic sympathetic chain with endoscopic thoracic sympathectomy (ETS). However, some side effects, particularly compensatory sweating (CS), are the limitations of this procedure. ⋯ This study demonstrates that older age, operation level, facial blushing, and high BMI are risk factors for CS, as have been shown in several similar studies. An interesting finding of the present study is that there was a decreased incidence of CS among patients with plantar sweating. This situation may help us to distinguish high risk for CS before ETS operation.
