Strategy of surgical management for pulmonary atresia with intact ventricular septum and mid-term follow-up / 中国胸心血管外科临床杂志

@#To evaluate the surgical strategy and follow-up for pulmonary atresia with intact ventricular septum (PA/IVS) in our heart center. Methods    From January 2008 to December 2018, 151 patients with PA/IVS were divided into two groups: a one-stage surgery group (26 patients), including 17 males and 9 females at an average age of 14.7±13.2 months, and a staged surgery group (125 patients) including 72 males and 53 females at an average age of 6.4±6.3 months. The clinical effectiveness of the two groups were analyzed. Results    All patients were followed up for 1-11 years. Eighteen patients died and 19 patients were lost to follow-up. The 1-year, 5-year and 10-year survival rate was 90.2%, 87.0%, and 85.2%, respectively. Two patients died in the one-stage surgery group. Twelve patients died after initial surgery, and 4 patients died after final operation in the staged surgery group. The Z value of tricuspid valve (P=0.013) and severe right ventricular dysplasia (P=0.025) were the risk factors of postoperative death in the patients with PA/IVS. Furthermore, 58 patients completed final operation, and the total number of the final operation (including one-stage radical surgery) accounted for 55.6% (84/151). Five patients accepted the re-operation intervention in the medium-term follow-up. The rest of the patients recovered well. Only 2 patients were classified as grade Ⅲ in cardiac function, and the rest patients were classified as gradeⅠ-Ⅱ. Conclusion    According to the degree of right ventricular hypoplasia, the age at operation and the presence or absence of coronary artery malformation, the individualized surgical strategy could significantly improve the success rate of PA/IVS, and early completion of right ventricular decompression operation is conducive to improve the chance for biventricular repair.

Effect of off-pump pulmonary valvotomy as the initial surgery for pulmonary atresia with intact ventricular septum: A single-center clinical analysis / 中国胸心血管外科临床杂志

@#Objective    To evaluate the effect of off-pump pulmonary valvulotomy for the patients with pulmonary atresia with intact ventricular septum (PA/IVS). Methods    The clinical data of 61 PA/IVS patients who underwent off-pump right ventricular decompression surgery in our hospital from January 2013 to September 2019 were retrospectively analyzed, including 37 males and 24 females, with an average age of 29.7 (2.0-86.0) d and weight of 4.1 (2.5-6.9) kg. Thirty-nine patients received off-pump pulmonary valvulotomy (an open-view valvulotomy group) and 22 patients received balloon valvuloplasty through the right ventricle pulmonary valve (a hybrid therapy group). The postoperative mortality, early re-intervention, and completion of final operation of the two groups were compared. Results    There were 2 deaths in the study with a mortality rate of 3.3% (2/61), and the mortality rate of the two groups was not significantly different (2.6% vs.4.5%, P=0.68). The rate of early re-intervention in the two groups was 5.3% and 19.0%, respectively (P=0.09). There was no statistical difference in intubation time (56.0±25.9 h vs. 62.0±28.9 h, P=0.41), ICU retention time (4.7±2.9 d vs. 5.5±2.2 d, P=0.23) and postoperative hospital stay time (3.9±0.9 d vs. 4.3±1.1 d, P=0.38) between the two groups. The follow-up time was 45.3 (4.0-84.0) months. There were 5 patients lost to follow-up. During the follow-up period, in the open-view valvulotomy group, 17 patients did not need further operation, 13 patients completed the final operation. In the hybrid therapy group, 7 patients did not need further operation, 8 patients completed the final operation. Heart function classification of all patients was in New York Heart Association class Ⅰ-Ⅱ. Conclusion    Compared with the hybrid therapy, off-pump pulmonary valvulotomy for PA/IVS also has the advantages of simple operation, short operation time and high survival rate, and it may be easier to be promoted in clinical application because of its more economic benefits and relatively lower re-intervention rate.

Efficacy of Hybrid Therapy and Bismuth Quadruple Therapy in Treatment of Helicobacter pylori Infection / 胃肠病学

Bismuth quadruple therapy is recommended as a first-line therapeutic regimen for Helicobacter pylori (Hp) infection in China.However, the renal toxicity induced by bismuth resulted in limitation of its clinical use.Aims: To assess the efficacy and safety of hybrid therapy for initial eradication of Hp infection.Methods: One hundred and fifty-two patients proved to be positive for Hp infection and treatment-na(i)ve at the Fuzhou General Hospital of Nanjing Military Command of Chinese PLA from Jan.2014 to Dec.2015 were enrolled and randomized to receive either hybrid therapy (esomeprazole and amoxicillin for 7 days, followed by esomeprazole, amoxicillin, clarithromycin and metronidazole for 7 days) or bismuth quadruple therapy (esomeprazole, amoxicillin, clarithromycin and colloidal bismuth pectin for 14 days).Hp eradication was assessed by 14C/13C-urea breath test at a minimum of 4 weeks after the end of treatment.Results: No significant differences were found in general status between the two groups at baseline (P>0.05).A total of 149 patients completed the therapy.In hybrid therapy group the eradication rate was 97.4% (75/77) by ITT analysis and 98.7% (75/76) by PP analysis;while in bismuth quadruple therapy group the eradication rates by ITT and PP analyses were 89.3% (67/75) and 91.8% (67/73), respectively.Hybrid therapy was superior to bismuth quadruple therapy (P all <0.05).Although the incidence of adverse events was higher in hybrid therapy group than in bismuth quadruple therapy group (29.9% vs.16.0%, P<0.05), none of the patients discontinued the therapy because of severe adverse events.Conclusions: Hybrid therapy showed better efficacy than bismuth quadruple therapy for treatment of Hp infection, and the adverse events were well tolerated.Hybrid therapy might be used as first-line treatment for Hp infection.

Clinical observation of Hybrid therapy in repairing muscular ventricular septal defect associated with additional congenital heart disease / 天津医药

Objective To discuss the clinical efficacy of Hybrid therapy in repairing muscular ventricular septal defect (mVSD) associated with additional congenital heart disease in children. Methods The clinical data of 18 patients (9 males and 9 females) admitted to our hospital from December 2012 to December 2016 were retrospectively analyzed. The mainly additional congenital heart diseases were tetralogy of fallot, coarctation of aorta, complete transposition of great arteries, double outlet right ventricle, mitral valve cleft. All of the patients were treated with corrective surgeries of Hybrid therapy under direct supervision. Results Four patients died through the operation. One patient died of postoperative infection, 1 patient died of the complex malformation, which wasn′t repaired, 1 patient died of mitral valve damage for occluder device replacement, 1 patient died of arrhythmia with unknown reason. One patient received non planned re-operation because of the huge membranous ventricular septal defect for the first stage surgery, in which no mVSD was found. All the rest patients were completed their first stage treatment and discharged from hospital. During the followed ups ( 1 month to 5 years), no patient died. The occluder devices were in correct position in 14 patients, no residual shunt was found in 12 cases. The cardiac function was normal in 13 cases [ejection fraction (EF)=0.63 ± 0.05]. Conclusion It is safe and effective for the treatment of mVSD using Hybrid therapy, which is especially suitable for patients with complex cardiac malformations and patients with complicated vascular situation.

Clinical observation of the effect of one stop hybrid approach for tetralogy of fallot with aorta pulmonary collateral arteries / 中国介入心脏病学杂志

Objective To summarize the clinical effects of one stop hybrid approach for treating the tetralogy of fallot complicated with aorta pulmonary collateral arteries. Methods From Janu 2008 to June 2013, 79 cases of tetralogy of fallot were complicated with aorta pulmonary collateral arteries with mean age (5.4±3.9) years and weight (18.2±5.7) kg. All patients were diagnosed by echocardiography examination and accepted 64-row CT for demonstration of no dysplasia in pulmonary ressels, McGoon index was (1.7±0.6) and Nakata index was (176.7±7.3). 76 cases had aorta pulmonary collateral arteries for preliminary screening, and accepted cardiovascular angiography before operation. 3 cases were misdiagnosed before surgery and were confirmed by cardiovascular angiography after operation. Results There were 4 deceased cases with an operative mortality of 5.1%. 1 case died of lung infection and 3 cases died of refractory heart failure. In all aorta pulmonary collateral arteries, the smallest diameter was 2.5 mm, the largest was 9.4 mm, average (5.3±2.1) mm. 2 to 21 coils were implanted in respective case with an average of 10.2 coils per case. The maximum number of coils implanted in 1 single ressel was 9. The average number of ressels occluded was 3.7 (range from 1 to 11 ressels) in each case. One case received second closure due to re-open of collateral arteries on neo-vasculanigation. 14 cases had lung infection and 3 cases had pulmonary edema post operation. 75 cases were followed up for 3-72 months. 4 cases with post operative heart function of NYHA gradeⅢtoⅣand all other cases with gradeⅡon higher. Conclusions Peri-operative hybrid management for aorta-pulmonary collateral arteries can increase the operative success rates and reduce complications.
