Résumé

Background: Numerous studies have reported predictors of new‑onset postoperative atrial fibrillation (POAF) following cardiac surgery, which is associated with increased length of stay, cost of care, morbidity, and mortality. The purpose of this study was to examine the association between preoperative diastolic function and occurrence of new‑onset POAF in patients undergoing a variety of cardiac surgeries at a single institution. Methods: Using data from a prospective study from November 2007 to January 2010, a retrospective review was conducted. The diastolic function of each patient was determined from preoperative transthoracic echocardiograms. Occurrence of new‑onset POAF was prospectively noted for each patient in the original study. Demographic and operative characteristics of the study population were analyzed to determine predictors of POAF. Results: Of 223 patients, 91 (40.8%) experienced new‑onset POAF. Univariate predictors of POAF included increasing age, male gender, operations involving mitral valve repair/replacement, nonsmoking, hypertension, increased intraoperative pulmonary artery pressure, grade I diastolic dysfunction, abnormal diastolic function of any grade, decreased medial e’, elevated medial E/e’, and increased left atrial volume. Multivariate predictors of POAF included increasing age, increased left atrial volume, and elevated initial intraoperative pulmonary artery pressure. Even after exclusion of patients with hypertrophic obstructive cardiomyopathy or those undergoing mitral valve operations, diastolic dysfunction was not a multivariate predictor of POAF. Conclusions: In the patient population studied here, preoperative diastolic dysfunction was not predictive of POAF. In addition to increasing age, initial intraoperative pulmonary artery systolic pressure and left atrial volume were both significant multivariate predictors of POAF.

Résumé

Acute intraoperative superior vena cava (SVC) syndrome is an exceedingly rare complication in the cardiac surgical population. We describe the case of a 71-year-old female undergoing multi-vessel coronary artery bypass grafting who developed acute intraoperative SVC syndrome following internal thoracic artery harvest retractor placement. Her symptoms included severe plethora, facial engorgement and scleral edema, which was associated with hypotension and severe elevation of central venous pressure. Transesophageal echocardiography was crucial in the diagnosis, management, and optimal retractor placement ensuring adequate SVC flow. Potential causes of intraoperative SVC syndrome are reviewed as well as management options.
