ABSTRACT

Objective:To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome. Conclusion:Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.

ABSTRACT

Objective:To evaluate the long-term results of combined ganglion plexus ablation(GPA) during radiofrequency ablation(RF) with long-standing persistent atrial fibrillation(LSP-AF).Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent valve operations concomitant RF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events. Propensity score matching conducted by RF and RF+ GPA resulted in 102 patients per group.Results:Independent predictors for rhythm success at 1 year were combined GPA( OR=0.205, P=0.005), smaller left atrium size( OR=1.091, P=0.000); at 5-year and 8-year were a shorter history of AF( OR=1.069, P=0.023; OR=1.066, P=0.030), and smaller left atrium size( OR=1.091, P=0.000; OR=1.086, P=0.000). After matching, RF+ GPA group had significantly higher sinus rhythm(SR) without antiarrhythmic drugs(AADs) at 6 months(91.3% vs. 79.8%, P=0.026), 1-year(90.2% vs. 78.5%, P=0.028), but there were no difference between the two groups at 5-year(64.8% vs. 64.4%, P=0.956), and 8-year(53.3% vs. 50.6%, P=0.711). During the 6 postoperative months, fewer patients in the RF+ GPA group underwent follow-up cardioversions(2.0% vs. 8.8%, P=0.030). Actuarial survival curves did not differ significantly between the 2 groups( HR=1.327, 95% CI 0.4633-3.802, P=0.598). Conclusion:The combination of GPA can be effective at the early postoperative stage for SR restoration in Maze Ⅳ procedures for the treatment of LSP-AF in heart valve surgeries, particularly for lower AADs use and lower cardioversions. However, this effect will gradually diminish after one year.

ABSTRACT

@#Tetralogy of Fallot is the most common cyanotic congenital heart disease. The pathological anatomy changes include ventricular septal defect, right ventricular outflow tract stenosis, aortic stradding and right ventricular hypertrophy. At present, the diagnostic criteria and treatment strategies of this disease are basically unified. However, there are controversies about the timing and method of surgical treatment. Based on the evidence-based information provided in the literature and the opinions of domestic experts of China, we formulate a consensus of Chinese experts to further standardize the surgical treatment of tetralogy of Fallot.

ABSTRACT

@#Objective    To analyze the recovery rule of atrial contractility (AC) function after Maze Ⅳ procedure of valvular atrial fibrillation (AF). Methods    In our hospital from March 2016 to April 2018, 103 patients who underwent cryoablation Maze Ⅳ procedure due to mitral valve lesions associated with persistent or long-term persistent AF were enrolled. There were 42 males and 61 females, with an average age of 58.5±9.1 years. Electrocardiogram and echocardiography were followed up at discharge and 1, 3, 6, 12 months after procedure. A multivariate Cox analysis of predictive factors for AC recovery was applied. Results    All the 103 patients were followed up for 1 year. The recovery rate of AC increased gradually after operation. It was not until 3 months after procedure that most of the right atrial contractility (RAC) was accompanied by synchronous recovery of the corresponding left atrial contractility (LAC, Kappa coefficient≥0.40, P<0.05). However, the coexistence of sinus rhythm (SR) and bilateral AC was not consistent well until 1 year after operation (Kappa coefficient≥0.40, P<0.05). One year after procedure, the recovery rates of SR and bilateral AC were 86.4% (89/103) and 66.0% (68/103) respectively. By Cox multivariate regression analysis, longer preoperative AF duration (P=0.040), larger preoperative left atrial diameter (LAD, P=0.003), and AC deletion 3 months after surgery (P=0.037) were predictive factors for AF recurrence in the middle and advanced stages (>3 months) after Maze surgery. At the same time, longer preoperative AF duration and larger preoperative LAD were also negative predictors of middle and late recovery of LAC and bilateral AC (All P<0.05). Receiver operating characteristic curve analysis showed that the best critical value of preoperative AF time and preoperative LAD for prediction of AC recovery was 37 months (sensitivity 99.6%, specificity 76.3%) and 60.5 mm (sensitivity 98.5%, specificity 78.9%), respectively. Conclusion    The recovery of AC after Maze procedure is a dynamic improvement process. Early recovery of AC is beneficial to the stable maintenance of SR in the future. Prolonged duration of AF and enlarged LAD have adverse effects on the outcome of Maze Ⅳ procedure.

ABSTRACT

@#Objective    To analyze factors affecting the recovery of postoperative left ventricular function in patients with valvular disease combined with heart failure with reduced ejection fraction [HFrEF, left ventricular ejection fraction (LVEF)<40%]. Methods    The clinical data of 98 patients with valvular disease combined with HFrEF who underwent surgeries in our hospital from January 2011 to June 2018 were retrospectively analyzed, including 75 males and 23 females aged 9-78 (55.3±11.9) years. Results    A total of 15 patients were dead after the operation, including 4 deaths within 3 months and 11 mid-long-term deaths after the operation. Ninety-one patients were followed up for more than 6 months (10 months to 8.6 years). The postoperative cardiac function (NYHA) of 91 patients was classⅠ-Ⅱ, the LVEF of 18 (19.8%) patients increased more than 10%, that of 47 (51.6%) patients maintained at the preoperative level, and that of 26 (28.6%) patients decreased. Postoperative LVEF was more prone to recover in HFrEF patients with sinus rhythm before operation (P=0.038), valvular disease mainly in aortic valve (P=0.026), obvious reduction of left ventricular end diastolic diameter in early postoperative period (P=0.017), and higher systolic pulmonary artery pressure (SPAP) before operation (P=0.018). The risk factors for postoperative LVEF deterioration included large left atrium before operation (P=0.014), smaller left ventricle end systolic diameter before operation (P=0.003), and fast heart rate after operation (P=0.019). Conclusion    Mitral valve prolapse patients with obviously increased left ventricular diameter should receive operation as soon as possible. HFrEF patients with aortic valve disease should receive operation positively. The operation efficacy is satisfactory in the HFrEF patients with high SPAP.

ABSTRACT

Cholangiocarcinoma is a malignant tumor originating from bile duct epithelium, with insidious onset and high degree of malignancy. Most of the patients were diagnosed at the middle and late stages and the survival rate is very poor. The etiology of cholangiocarcinoma is still unknown. Billary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, biliary mucinous cystic neoplasm and intraductal tubular/tubulopapillary neoplasm of the bile duct are considered as precancerous lesions of cholangiocarcinoma. Improving the understanding of precancerous lesions of cholangiocarcinoma, and early treatment of these lesions are important for enhancingthe patients’ quality of life. However, the current understanding of precancerous lesions of cholangiocarcinoma is limited. Development of molecular diagnostic technology is deeply needed. And sensitive and specific biomarkers are urgently needed for the early diagnosis of the high-risk persons accurately, so as to achieve " early detection, early diagnosis and early treatment" . This article reviews how to recognize and deal with precancerous lesions of cholangiocarcinoma.

ABSTRACT

To evaluate the long term cardiopulmonary function after Fontan operation. Methods 10 patients who received Fontan operation were followed for(26 ±4) years in our hospital. 7 males and 3 females,(30. 7 ± 13. 2) years old(20 -60 years). All patients were diagnosed by echocardiography, CTA, 24 h ECG, cardiac catheterization, pulmonary angiography, radionuclide pulmonary blood perfusion and cardiopulmonary exercise test. Results Echocardiography shows: LVEF(0. 49 ± 0. 04), more than moderate atrioventricular valve regurgitation in 7 cases. CTA shows: there was no anastomotic stenosis, arteriovenous fistula in 4 cases. 24 h ECG shows: sinus rhythm in 7 cases, frequent paroxysmal atrial tachycardia in 1 case, atrial flutter in one and atrial fibrillation in one. Cardiac catheterization and pulmonary angiography show: the average pulmonary artery pressure(17. 8 ±2. 0)mmHg, average pulmonary resistance(4. 17 ±0. 56) woods. Radionuclide pulmonary blood perfusion shows: pulmonary blood of upper lung was reduced significantly with unbalanced distribution. Cardiopulmonary exercise test shows: both of lung ventilation function and heart reserve function decreased moderately or severely. Protein losing enteropathy was found in 1 case. Conclusion The decrease of cardiopulmonary function is found after Fontan operation during the long-term follow up for 20 years, especially for cardiac function. More attention should be paid to the early postoperative atrioventricular valve regurgitation. Unbalanced distribution of pulmonary blood is Found in long term. The incidence of arrhythmia after extra conduit Fontan operation is lower than other methods.

ABSTRACT

Objective To study the radiofrequency ablation (RA) and vagal denervafion (VD) in surgical treatment of long-standing atrial fibrillation (AF) associated with rheumatic heart disease (RHD).Methods Retrospective analysis the cardiac rhythm by 24-hour Holter monitoring during 5-year follow-up after total Maze procedure accompanied rheumatic mitral valve replacement.Between June 2006 and December 2007,a total of 173 consecutive patients with long-standing AF-associated RHD underwent mitral valve replacement and ablation maze procedure,92 cases had RA alone and 81 had RA + VD.Results Although Kaplan-Meier curve shows that the freedom from AF at 5 years follow-up time were similar(P =0.718),the percentage of antiarrhythmic drug therapy was significant higher in the RA group during early postoperative period(4th month,54.1% vs.34.7%,P=0.017;5th month,39.2% vs.21.3%,P=0.018;6th month,23.0% vs.10.7%,P =0.044),and the percentage of those free by AF was significant lower(6th month,82.2% vs.93.8%,P =0.023;1st year,76.1% vs.89.9%,P=0.019).Conclusion Total maze procedure with bipolar radiofrequency ablation is effective to treat longstanding AF associated with rheumatic valve disease.Vagal denervation helped to maintain stable sinus rhythm and lower antiarrhythmic drug therapy at the early stage,but there was no additional benefit after the 1 st year of follow-up,it may be caused from the reactivation of vagal plexus electrical activity.

ABSTRACT

Objective@#To evaluate the reliability and validity of warning signs checklist developed by the National Health and Family Planning Commission of the People′s Republic of China (NHFPC), so as to determine the screening effectiveness of warning signs on developmental problems of early childhood.@*Method@#Stratified random sampling method was used to assess the reliability and validity of checklist of warning sign and 2 110 children 0 to 6 years of age(1 513 low-risk subjects and 597 high-risk subjects) were recruited from 11 provinces of China. The reliability evaluation for the warning signs included the test-retest reliability and interrater reliability. With the use of Age and Stage Questionnaire (ASQ) and Gesell Development Diagnosis Scale (GESELL) as the criterion scales, criterion validity was assessed by determining the correlation and consistency between the screening results of warning signs and the criterion scales.@*Result@#In terms of the warning signs, the screening positive rates at different ages ranged from 10.8%(21/141) to 26.2%(51/137). The median (interquartile) testing time for each subject was 1(0.6) minute. Both the test-retest reliability and interrater reliability of warning signs reached 0.7 or above, indicating that the stability was good. In terms of validity assessment, there was remarkable consistency between ASQ and warning signs, with the Kappa value of 0.63. With the use of GESELL as criterion, it was determined that the sensitivity of warning signs in children with suspected developmental delay was 82.2%, and the specificity was 77.7%. The overall Youden index was 0.6.@*Conclusion@#The reliability and validity of warning signs checklist for screening early childhood developmental problems have met the basic requirements of psychological screening scales, with the characteristics of short testing time and easy operation. Thus, this warning signs checklist can be used for screening psychological and behavioral problems of early childhood, especially in community settings.

Objective To evaluate the value of multi-modality imaging (PET/CT+CAG+CMRI) in post myocardial infract (MI) patients followed coronary artery bypass graft (CABG) and autologous bone marrow stem cell (BMSC) therapy.Methods A total of 43 patients with MI (27 males, 16 females, age range: 47-72 years) were prospectively enrolled in the year 2012 between January and December.All patients underwent CABG+BMSC transplantation and were divided into 3 groups according to the time interval between two treatments (group 1: 0-3 d;group 2: 4-14 d;group 3: 15-30 d).All patients were orderly scanned with CMRI, PET/CT (13N-NH3·H2O/18F-FDG) and CAG at different time-points pre-/post-treatment.The quantitative parameters included vascular stenosis degree(VSD), LVEF, percentage size of infarction (PSI), the number of segments in mismatched myocardial perfusion/metabolic and the K value for radioactive distribution grading.One-way analysis of variance and the least significant difference t test were used to compare parameters before and after treatment in the same group and among three different groups.Results Regarding PET/CT diagnostic efficacy of abnormal myocardial segments, the sensitivity, specificity, positive predictive value and negative predictive value were 95.4%(540/566), 87.3%(144/165), 96.3%(540/561) and 84.7%(144/170), respectively.After CABG and BMSC transplantation treatments for 12 months, VSD decreased significantly((69.1±9.5)%;F=12.854, P0.05).PSI of patients in group 2 decreased greatly after 12 months treatment ((35.70±12.59)%;F=3.792, t values:-2.916-4.059, all P0.05).Conclusions Multi-modality imaging may be used for accurately detecting abnormal myocardium and predicting prognosis.CABG+BMSC therapy during day 4-14 post-MI may temporarily improve perfusion and metabolism in viable myocardium, but the long term prognosis seemed not be improved.

ABSTRACT

Objeetive We sought to compare the safety and efficacy of cut-and-sew Cox-maze Ⅲ procedure for atrial fi brillation associated with degenerative mitral regurgitation,by comparing with patients without atrial fibrillation.Methods From May 2013 to November 2015,217 patients underwent mitral valve repair were enrolled,including 145 without atrial fibrillation(control group) and 28 received concomitant cut-and-sew Cox-maze Ⅲ procedure (treatment group).Propensity scores were calculated on the basis of 16 known preoperative factors and yielded the best matched patients.Safety and outcomes were compared between the two matched groups.Results 28 pairs of patients were matched successfully.No hospital deaths occurred and the major complications showed no statistical differences (P > 0.05).Cardiopulmonary bypass time and crossclamp time,proportion of amiodarone use and temporary pacemaker use,and postoperative hospital stay in the treatment group were higher than those in the control group(P <0.001).Patients were followed up from 6 months to 3 years,and no patients occurred deaths and strokes.After 6 months,there were no significant differences in the rates of sinus rhythm and drug free between the two groups (P > 0.05).In both groups,left atrial diameter and left ventricular diameter decreased,and ejection fraction increased compared with those before operation.Atrial function in the treatment group recovered 3 years after operation.At the latest follow-up,patients in both groups were all at NYHA functional class Ⅰ.Conclusion The additional cut-and-sew Cox-maze Ⅲ procedure for treatment of degenerative mitral disease complicated by atrial fibrillation does not increase the operative risks of mitral valve repair,and had early and mid-term outcomes similar to that of patients without atrial fibrillation.
