Background: The number of studies of long‐term follow up to adolescence is very low on spontaneous closure (SC) of perimembranous ventricular septal defects (P‐VSD) in children not undergoing surgical closure because of small left‐to‐right shunting. Methods: Seventy patients with a P‐VSD with pulmonary‐to‐systemic flow ratio (Qp/Qs) < 1.7 underwent cardiac catheterization at the age of 2–10 years (mean, 5.1 years). Excluding 22 patients who dropped out by 15 years, 48 were selected. Qp/Qs ranged from 1.00 to 1.68 (mean, 1.17). The average follow‐up period of 37 patients excluding the SC patients was 17.8 years. They were classified according to Qp/Qs into three groups: group I, 1.4 ≤ Qp/Qs < 1.7; group II, 1.2 ≤ Qp/Qs < 1.4; and group III, 1.0 ≤ Qp/Qs < 1.2. Results: SC occurred in 11 patients (23%). SC rates in group I and II were lower than those in group III (I, 0/8 0%; II, 1/10 10%; III, 10/30 33%). In 23 patients (48%), an aneurysm of the ventricular membranous septum (AVMS) was detected, but no significant relationship was found between the presence of AVMS and SC rate. Conclusions: SC occurred in 23% of patients with a P‐VSD of Qp/Qs < 1.7 up to adolescence. But a P‐VSD of Qp/Qs ≥ 1.2 showed no tendency to close spontaneously. The factor most influencing SC of P‐VSD after school age seemed to be the shunt ratio. 相似文献

Miyake T Shinohara T Inoue T Marutani S Takemura T 《Acta paediatrica (Oslo, Norway : 1992)》2011,100(10):e158-e162
Aim: To evaluate the timing and frequency of spontaneous closure of the muscular trabecular ventricular septal defect (VSD). Methods: We performed a historical cohort study for which 150 patients <3 months of age (median age, 9 days) diagnosed as having a muscular trabecular VSD were selected. Median age at latest follow‐up was 2.8 years. Another 32 patients diagnosed after 3 months of age were also reviewed. Using colour Doppler, defects were classified into three groups: anterior, apical and midventricular. Results: Spontaneous closure occurred in 126 patients (84%): anterior, 36 of 47 (83%); apical, 26 of 31 (84%); and midventricular, 64 of 72 (89%). Multivariate analyses showed a lower frequency of spontaneous closure for patients of age of ≥20 days at initial echocardiography [hazard ratio 0.60, 95% confidence interval (CI) 0.39–0.89] and for anterior and apical muscular trabecular VSD (hazard ratio 0.66, 95% CI 0.47–0.95). The prevalence of the midventricular muscular trabecular VSD was significantly lower in patients ≥3 months of age at initial echocardiography than in those <3 months (p = 0.010). Conclusion: We infer that midventricular muscular trabecular VSD tends to close spontaneously earlier and more frequently than either anterior or apical muscular trabecular VSD. 相似文献

??Abstract??Objective To evaluate the clinical effect of transcatheter closure for ventricular septal defect in infants and young children. Methods Clinical data from 184 children under 3 years old who underwent the transcatheter VSD closure from Jan. 2011 to Dec. 2012 were analyzed. Results Procedure was successful in 176 cases ??95.7%??. No death occurred?? residual shunt in 13 cases?? tricuspid inflow accelerated in 2 cases?? late-onset complete atriovenous block in one case ??6 months after procedure??. All cases had no vascular complications. Conclusion Transcatheter closures for ventricular septal defects are effective in small children. Long-term follow-up is needed to evaluate the safety of this operation. The keys to the success of operation are the proper indications,suitable apparatus,skillful vascular punction and good anaesthetic management. 相似文献

Intrauterine closure of membranous ventricular septal defects: Mechanism of closure in two autopsy specimens 总被引:2,自引:0,他引:2
Summary Anatomic evidence of intrauterine closure of ventricular septal defects (VSDs) has been reported rarely. Between 1985 and 1990, 112 autopsies were performed at the Mayo Clinic on third trimester stillborns and infants who died during the first week of life. There were 21 (19%) cases of congenital heart disease. VSD was found in 12 (11%) cases: in eight (7%) as a part of a more complex heart defect and in four (4%) as an isolated lesion. Two cases with membranous VSDs with tricuspid valve tissue partially occluding the ventricular septal defect were found. A 2280-g female infant (case 1) with trisomy 18 died at 4 days of age. Autopsy revealed bilateral superior venae cavae, a large atrial septal defect, cor triatriatum, an atypical tricuspid valve with large septal leaflet partially obstructing a large membranous VSD, a hypoplastic right ventricle, and severe pulmonic stenosis. A 2610-g female infant (case 2), born with congenital heart block died at 4 days of age. Autopsy revealed cor triatriatum dexter obstructing the tricuspid orifice, a large membranous VSD partially obstructed by the septal leaflet of the tricuspid valve, four small muscular VSDs, and pulmonic stenosis. These cases suggest that closure of membranous VSDs may gegin in utero and the mechanism of closure is similar to that reported postnatally. 相似文献

Meberg A, Otterstad JE, Frøland G, Sørland S, Nitter-Hauge S. Increasing incidence of ventricular septal defects caused by improved detection rate. Acta Pzdiatr 1994;83:653–7. Stockholm. ISSN 0803–5253
In a population-based study in childrcn born alive during the 10-year period from 1982 to 1991 ( n = 22 810), ventricular septal defects (VSDs) were diagnosed in 127 cases, an incidence of 5.6 per 1000. The incidence was significantly higher in the cohort of children born during the 6-year period from 1986 to 1991 than among those born in the preceding 4-year period, 1982–1985 (6.5 and 4.0 per 1000 respectively; p < 0.05). The increase was caused entirely by an increased detection rate of small defects in the muscular part of the interventricular septum after introducing echocardiography as a standard method for investigating suspect congenital heart defects in the neonatal period. This also explained entirely an increase in the total incidence of congenital hcart defects to 10.6 per 1000 in the last period from 8.4 per 1000 in the first, although this increase was not significant ( p > 0.05). Morc children born in 1986–1991 had spontaneous closure of their VSDs (75.5%) than those born in 1982–1985 (51.5%) ( p<0.05 ). In 69.3% of patients the VSDs closed during the first year of life. For the cohort born in 1986–1991, 84.6% of the defects located in the muscular part of the septum closed spontaneously. Small defects in the muscular part of the interventricular septum with spontaneous closure in early life may represent the tail of a normal developmental process, and not defects in the sense of malformations. 相似文献

OBJECTIVE: The main aim of this study was to determine the understanding and perception of parents following the diagnosis of a minor cardiac abnormality, namely a small ventricular septal defect, in the child. Other aims included discovering the reasons behind these perceptions and whether they affected the parents' management of their child and his/her cardiac problem. METHODS: Fifty-six infants and children from two tertiary centres and the private practices of the participating cardiologists were enrolled over a 5-month period. Questionnaires were prepared and distributed to all their parents. RESULTS: Complete data was obtained from 40 parents. Close to 80% of the parents perceived the small ventricular septal defect as a minor problem and most understood the nature of the defect. However, when asked about precautions for their child, only two-thirds recalled the need for antibiotic prophylaxis. Most parents experienced distress and anxiety when told initially of the diagnosis but none reportedly restricted their child's physical activity. CONCLUSIONS: Most parents have a clear understanding and perception of their child's small ventricular septal defect. There is a need for further improvement to facilitate parental understanding, especially with regard to the need for antibiotic prophylaxis. 相似文献

目的 通过分析膜周部室间隔缺损(perimenbranous ventricular septal defects,PMVSD)封堵治疗术前、术中和术后发生心律失常的情况,探讨介入治疗发生心律失常的相关影响因素,以期降低术后心律失常的发生率.方法 分析2005年11月至2008年1月行封堵治疗的65例先心病室间隔缺损患者封堵术前、术中和术后心律失常的发生率、类型及其可能的相关因素.结果 65例室间隔缺损患者术前有7例心律失常,表现为不完全或完全性右束支阻滞(IRBBB或CRBBB)、左前分支阻滞(LAH)等.术中可见多种类型的心律失常,其中在导丝和输送鞘通过室间隔时多出现房室传导阻滞(AVB)、交界性逸博、室性早博、室内差异性传导、室性心动过速等.术后心律失常发生率为12.3%(8/65),分别为l度房室传导阻滞2例,ILBBB 1例,LAH 1例,IRBBB 3例,室性早博1例,与术中的心律失常情况有一定的关系.术前已存在的7例心律失常经封堵治疗后,有1例Ⅰ度房室传导阻滞合并左前分支阻滞,其余无变化,随访未出现新的心律失常.对封堵术后心律失常影响因素进行单因素分析,提示与封堵器大小、缺损距三尖瓣隔瓣、主动脉右冠瓣距离、术中动一静脉轨道建立时问、术中是否出现Ⅱ度或Ⅲ度房室传导阻滞密切相关.结论 临床选择VSD封堵器直径≤8 cm、缺损距主动脉右冠瓣和三尖瓣隔瓣距离≥3 cm的患者进行封堵治疗,可减少术后心律失常的发生率;术中建立轨道时间长短及有无发生Ⅱ度AVB和(或)Ⅲ度AVB,也是影响术后发生心律失常的重要因素.临床在把握介入治疗适应证的同时,重视PMVSD与传导系统的空间位置,避免选择过大的封堵器用于治疗,缩短手术时间,注意手术过程心电变化的提示作用,是降低PMVSD封堵术后发生严重心律失常的有效措施. 相似文献

Echocardiographic evaluation of the development of aortic valve prolapse in supracristal ventricular septal defect 总被引:1,自引:0,他引:1

The development and timing of aortic weve prolapse (AoVP) and aortic regugitation (AR) was studied by two limensional echocardiography in 99 consecutive patients with supracristal ventricular septal defect (VSD). Thirty patients (30%) had aortic valve prolapse (VSD+AoVP group), and 31 patients (31%) had AoVP with AR (VSD+AoVP+AR group). In the VSD+AoVP group, AoVP was detected first by echocardiography at the age of 6.8±4.2 years (mea±SD). In the VSD+AoVP+AR group, the interval from detection of AoVP to the appearance of Al was 3.4±2.0 years. The configuration of the prolapsed aortic valve was echocardiographically classified into two types: teardrop type (small) prolapse and box type (large) prolapse. The frequency of tear-drop tyrolapse was not significantly different between VSD+AoVP and VSD+AoVP-AR groups (43% versus 32%, respectively), indicating that even minor AoVP can result, AR. Four infants (4%) had AoVP at the ages of 1, 5, 7, and 11 months, respectively. All infants had tear-drop type prolapse. Two infants developed AR by colour flow mapping at the ages of 3 and 11 months, and the interval from prolapse to AR was only 2 and 4 months, respectively.Conclusion Aortic valce, involement can develop under the age of 1 year in supracristal VSD. Regular evaluation by two-dimensional echocardiography with colour flow mapping is important in the followup of children with supracristal VSD. 相似文献

Summary Left ventricular function was examined angiographically in 64 patients with ventricular septal defect and 13 postoperative patients with a preoperatively large shunt (postoperative group). The unoperated 64 patients were divided into three groups; small (left-to-right shunt ratio <35%), moderate (35%–50%), and large (>50%). The control group consisted of 27 patients with Kawasaki disease. For assessing left ventricular function, left ventricular shape and the end-systolic wall stress to end-systolic volume index ratio, as well as left ventricular ejection fraction were examined. Left ventricular ejection fraction was higher in the small-shunt group (p<0.05) than in the control group, but normal in the other groups. Left ventricular end-diastolic shape was normal only in the small-shunt group and more spherical in the other groups. The large-shunt group alone manifested more spherical left ventricular end-systolic shape and lower end-systolic wall stress to end-systolic volume index (p<0.001). These findings suggest that the left ventricular dysfunction is present in patients with a left-to-right shunt larger than 50%, but this change was reversible in patients who underwent early repair of ventricular septal defect. 相似文献

膜周部室间隔缺损经导管封堵术后早期心律失常危险因素的探讨 总被引:22,自引:0,他引:22
目的心律失常是经导管封堵膜周部室间隔缺损术后的常见并发症,不仅影响术后心功能的恢复,而且直接关系到预后。分析18岁以内患者膜周部室间隔缺损经导管封堵术后早期心律失常及其危险因素,以期降低术后心律失常的发生率。方法2002年6月—2004年6月,89例膜周部室间隔缺损患者根据家长意愿接受了经导管应用Amplatzer装置及国产封堵器进行堵塞。80例应用AGA公司制造的Amlatzer膜周部室间隔缺损封堵器,9例应用国产封堵装置,术后定期行心脏超声及心电图检查。结果89例膜周部室间隔缺损封堵术均获成功。11例术后5d内发生了不同类型的传导阻滞,发生率为12%,分别为Ⅰ°房室传导阻滞1例,Ⅲ°房室传导阻滞1例,左前分支阻滞5例,不完全(部分)性右束支传导阻滞4例,完全性右束支传导阻滞3例,其中3例并发两种传导阻滞。分析本组心律失常的影响因素,发现:(1)室间隔缺损上缘距主动脉右冠瓣距离<3mm;(2)室间隔缺损直径≥8mm,封堵器直径≥10mm;(3)穿刺成功后动脉静脉(A-V)轨道建立时间≥60min及术中pH值<7·35与心律失常密切相关。结论心律失常是膜周部室间隔缺损封堵术后早期严重的并发症;严格选择手术适应证、缩短手术操作时间、防止酸中毒是降低膜周部室间隔缺损介入封堵术后心律失常发生率的有效措施。 相似文献
