Objective To report the experiences of cardiac valve operation in children. Methods Cardiac valve operations were performed in 87 children who were 58 male and 19 female between age of 4 to 14 years (mean 10.2 years). Of the 87 patients, 36 underwent mitral valve replacement, 13 aortic valve replacement, 6 mitral and aortic valve replacement, 13 aortic valvuloplasty, and 19 mitral valvuloplasty. Associated cardiac lesions were simultaneously managed. Results Postoperative complications included low car...

ObjectiveTo investigate the prognosis and risk factors of mild to moderate or moderate atrioventricular valve regurgitation (AVVR) after Fontan operation.MethodsA total of 34 patients with mild to moderate or moderate AVVR who accepted Fontan operation and atrioventricular valve (AVV) repair between 2004 and 2018 in our center were selected as an AVV repair group. The patients in the same period were matched as a control group by the ratio of 1 : 1-2. Finally 99 patients were included into this study, including 64 males and 35 females, with an average age of 63.4±36.3 months and weight of 17.3±6.7 kg. Grades of AVVR decreased more than 1 was defined as significant improvement. Endpoints of the study were death, Fontan takedown, AVV replacement. Risk factors including Fontan procedures, AVV repair procedures, cardiac anatomy were analyzed.ResultsPatients were followed up for 1.5 (0.3-4.0) years. Overall mortality was 15.2%. Most (82.4%) of AVV repair group accepted single AVV repair procedure while partial annuloplasty was the most common (52.9%). With the extension of follow-up, the degree of AVVR in the whole group showed a gradually increasing trend (r=0.352, P=0.000). Mild to moderate AVVR improved spontaneously after Fontan operation, while moderate AVVR did not. AVV repair could improve the degree of AVVR after moderate regurgitation, without increasing the surgical mortality, and regurgitation significantly decreased in 8.8% patients. AVV repair was not effective for mild to moderate AVVR and would increase surgical mortality. ConclusionAVV function shows a gradual downward trend after Fontan operation. AVV repair is effective for moderate AVVR, does not increase mortality, but the degree of improvement is limited. AVV repair is not effective for mild to moderate AVVR and increases surgical mortality.
Objective To evaluate the surgical characteristics, methods and clinical effect of pediatric valvoplasty through an analysis of valvoplasty in children in the age from 15 h to 14 years. Methods From January 1993 to June 2003, 376 children underwent valvoplasty. There were 349 cases (92.8%) of congenital heart disease and 27 cases(7.2%) of acquired heart disease. The procedure included mitral valvoplasty in 79 (19.4%), tricuspid valvoplasty in 159 (39.1%), aortic valvoplasty in 40 (9.8%), and pulmonary valvoplasty in 129(31.7%). Results There were 12 early deaths (3.2%) after the procedure. 297 patients were followed up from 1 month to 10 years (mean, 4.9±2.4 years). There were 2 late deaths (0.7%) after discharge. There were 5 cases (1.7%) of re-operation due to valve problem. Conclusions Valvoplasty should be the first choice in dealing with valve diseases in children. The effect of the valvoplasty works on the prognosis of the operation.
Objective To evaluate the surgical effects of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins stripping on primary deep venous valvular incompetence of the lower limb.Methods Seventy-eight patients (92 limbs) with primary deep venous valvular incompetence of the lower limbs received the operations of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins from 1997 to 2004. There were 65 males and 13 females, and their ages ranged from 32 years to 72 years (mean age of 52.5 years). The valvular reflux grades of these 92 limbs varied from Ⅲ to Ⅳ according to Kistner’s standard. A sleeve made from the stripped great saphenous vein was used in the indirect loop valvuloplasty of the superficial femoral vein. The early results of surgery were retrospectively analyzed. Results Pre-operative symptoms, such as edema, ulceration, pigmentation and heavy feeling of the performed limbs disappeared or were remarkably improved in 65 cases (76 limbs) after operation. Eight cases (10 limbs) had alleviative symptoms compared with pre-operative ones. Meanwhile, no improvement of symptoms was observed in 3 patients (4 limbs). Acute ilio-femoral vein thrombosis occurred in 2 patients (2 limbs), which manifested as more servious edema of the lower limbs than those before operation. The overall effective rate of surgery was 93.5%（86/92）, and the complications rate was 2.2% (2/92). Conclusion Indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose vein stripping is an effective and convenient way to correct the primary deep venous valvular incompetence of the lower limb. The surgical indications of this disease should be emphasized strictly to assure the good outcomes.
The clinical results of one-staged indirect valvuloplasty of the superficial femoral vein by wrapping an autogenous saphanous vein cuff to treat 20 patients with primary valvular incompetence of deep vein. The results following postoperative follow-up were 16 patients ahd striking improvement, excellent improvement in 2. venuos thrombosis in 1 and one failure. The operative procedure was introduced, the indications for operation was discussed, and the results were vealuated.
ObjectiveTo analyze the clinical efficacy of valve surgeries for infective endocarditis and the affecting factors, and compare the early- and long-term postoperative outcomes of different surgery approaches. MethodsThe patients with infective endocarditis who underwent valve replacement/valvuloplasty in our hospital from 2010 to 2022 were retrospectively collected. The clinical data of the patients were analyzed. ResultsA total of 343 patients were enrolled, including 197 patients with mechanical valve replacement, 62 patients with bioprosthetic valve replacement, and 84 patients with valvuloplasty. There were 238 males and 105 females with an average age of (44.2±14.8) years. Single-valve endocarditis was present in 200 (58.3%) patients, and multivalve involvement was present in 143 (41.7%) patients. Sixty (17.5%) patients had suffered thrombosis before surgery, including cerebral embolisms in 32 patients. The mean follow-up time was (60.6±43.8) months. Early mortality within one month after the surgery occurred in 17 (5.0%) patients, while later mortality occurred in 19 (5.5%) patients. Eight (2.3%) patients underwent postoperative dialysis, 13 (3.8%) patients suffered postoperative stroke, 6 patients underwent reoperation, and 3 patients suffered recurrence of infective endocarditis. Smoking (P=0.002), preoperative embolisms (P=0.001), duration of surgery (P=0.001), and postoperative dialysis (P=0.001) were risk factors for early mortality, and left ventricular ejection fraction ≥60% (P=0.022) was protective factor for early mortality. New York Heart Association classification Ⅲ-Ⅳ (P=0.010) and ≥3 valve procedures (P=0.028) were risk factors for late mortality. The rate of composite endpoint events was significantly lower in the valvuloplasty group than that in the valve replacement group. ConclusionFor patients with infective endocarditis, smoking and preoperative embolisms are associated with high postoperative mortality, multiple-valve surgery is associated with a poorer prognosis, and valvuloplasty has advantages over valve replacement and should be attempted in the surgical management of patients with infective endocarditis.
目的 探讨四维经食管超声心动图（4D-TEE）在瓣膜修复中的作用。 方法 2016 年 1 月我院对 3 例行二尖瓣修复和 1 例行主动脉瓣膜修复的患者采用西门子 SC2000 4D-TEE 进行术前术后评估，其中男 2 例、女 2 例，年龄38～59 （48.0±10.5）岁。同期采用二维经食管超声心动图指导二尖瓣和主动脉瓣修复的 13 例患者作为对照，其中男 8 例、女 5 例，年龄43～67（56.4±7.5）岁。 结果 术中 4D-TEE 可实时显示瓣叶的各项参数，如不同节段瓣叶高度、交界区面积、瓣叶面积、对合面的大小、窦管交界大小，瓣膜运动形态、主动脉管壁位移等信息。可根据内置软件建立个性化的瓣膜几何模型，动态模拟瓣膜启闭并直观呈现。对照组仅可显示某切面的瓣膜、腱索、乳头肌、心腔等信息。 结论 4D-TEE 跳过了对二维图像的解读步骤，更直观完整地显示了瓣膜形态和动态，可以通过它的辅助来进行更有效的手术决策。
