Objective To define the incidence and perioperative risk factors of new-onset atrial fibrillation for patients with preoperative sinus rhythm after successful mitral valve replacement.Methods Retrospective analysis was performed on 586 patients with preoperative sinus rhythm who underwent successful mitral valve replacement in our hospital from 1998 to 2008.The cases were classified into postoperative atrial fibrillation (AF group) or postoperative sinus rhythm (SR group).Twenty-nine risk factors including clinical and echocardiography data were selected into univariate analysis by using student' s t test or chi-squared test according to the data type.The factors with a value of P < 0.1 in univariate analysis were assessed by multivariate logistic regression.A value of P < 0.05 (two-sided) was considered to be statistically significant in multivariate logistic regression. ResultsOne hundred and eighteen patients had atrial fibrillation postoperatively. The incidence was 20.1%.Univariate analysis revealed that the factors including age,chronic lung disease,left ventricular mass,left atrial volume,right atrial volume,tricuspid valve regurgitation,heart failure,valvular pathology,postoperative prosthetic mitral effective orifice area index,postoperative mechanical ventilation time,serum levels of potassium and magnesium significantly increased the risk of postoperative atrial fibrillation.However,in multivariate logistic regression,age,left atrial volume and postoperative prosthetic mitral valve effective orifice area index and serum of potassium had significant statistically significances between AF group and SR group.Conclusion Age,left atrial volume,postoperative prosthetic valve effective orifice area index and serum of potassium were significant predictors of postoperative new-onset atrial fibrillation for patients with preoperative sinus rhythm after mitral valve replacement.

Objective The aim of the study was to analyze the predictive value of the European system for cardiac operative risk evaluation score (EuroSCORE) and the Society of Thoracic Surgeons predicted risk of mortality (STS-PROM) in -dult patients undergoing aortic valve replacement (AVR).Methods We carried out a retrospective statistical analysis on 521 adult patients undergoing AVR between 1999 and 2008 in Changhai hospital.Patients with concomitant coronary artery bypass grafting were also included.Excluded from this study were patients having surgery for congenital heart defects,aneurysm of thoracic aorta and atrial fibrillation.Operative mortality was defined as death before discharge from the hospital.The mortality risk calculation of EuroSCORE and STS-PROM for aortic valve procedures was performed by the online available EuroSCORE or STS score calculator.Based on the additive EuroSCORE risk calculation,patients were divided into low-risk,medium-risk and high-risk groups.The valuation of three different algorithms depended on the assessment of two features:calibration and discrimination.A comparison of observed and predicted mortality rates was also performed.Results A total of 521 patients were identified as having undergone aortic valve replacement.In-hospital mortality was 4% (21 cases) overall.The expected mortality for the additive,logistic EuroSCORE and the STS-PROM was 3.36%,2.82% and 1.25%,respectively.The observed to expected ratio was 1.2 for additive EuroSCORE,1.43 for logistic EuroSCORE and 3.23 for STS-PROM.The STS-PROM underpredicted observed mortality significantly ( P < 0.01 ) and showed poor calibration in predicting in-hospital mortality in the entire cohort,medium- and high-risk subgroups.The logistic EuroSCORE underpredicted observed mortality in the mediumrisk subgroup ( P < 0.05 ).EuroSCORE underpredicted in-hospital mortality in the high-risk subgroup with the observed-expected mortality rate of 1.84 for additive EuroSCORE and 1.46 for logistic EuroSCORE.The EuroSCORE in three subgroups showed poor discrimination in predicting mortality as well as the STS-PROM did in the medium- and high-risk subgroups ( ROC < 0.7).Conclusion Both the EuroSCORE and the STS-PROM give an imprecise prediction for individual operative risk in patients undergoing aortic valve replacement in our study.These algorithms seem unsuitable to identify a high-risk patient population undergoing isolated AVR.It is necessary to construct a risk stratification model for valve surgery according to the profiles of Chinese patients.
