目的:探讨肌部室间隔缺损封堵的超声心动图筛选适应证及价值。方法:应用HPsonos1500和5500彩色超声诊断仪检查12例拟行封堵术的患者,观测左右室侧缺损口大小、缺损残端距主动脉瓣和三尖瓣的距离。结果:9例封堵成功,左右室侧缺损口大小差异显著,分别为8.5±2.6(6.0~14.0)mm及6.1±1.2(4.0~7.0)mm,残端距主动脉右瓣距离6.0~13.0mm,距三尖瓣7.0~15.0mm,室缺多位于室间隔中部或调节束上方。3例封堵不成功,2例室缺口较大且左右室面大小相同,位于右室流入道部,放置封堵器时因出现Ⅲ度房室传导阻滞而放弃。另1例右室侧缺损口过小,造成穿隔失败。结论:用超声心动图筛选适应证对肌部室间隔缺损封堵成功与否有重要的作用。 相似文献

Residual muscular ventricular septal defects are surgical challenges, especially after the repair of complex congenital heart defects. We investigated perventricular device closure as a salvage technique in pediatric patients who had postoperative residual muscular ventricular septal defects.From February 2009 through June 2011, 14 pediatric patients at our hospital had residual muscular ventricular septal defects after undergoing surgical repair of complex congenital heart defects. Ten patients met our criteria for perventricular device closure of the residual defects: significant left-to-right shunting (Qp/Qs >1.5) or substantial hemodynamic instability (a defect ≥2 mm in size). The patients'' mean age was 20.4 ± 13.5 months, and their mean body weight was 10 ± 3.1 kg. The median diameter of the residual defects was 4.2 mm (range, 2.5–5.1 mm).We deployed a total of 11 SQFDQ-II Muscular VSD Occluders (Shanghai Shape Memory Alloy Co., Ltd.; Shanghai, China) in the 10 patients, in accord with conventional techniques of perventricular device closure. The mean procedural duration was 31.1 ±9.1 min. We recorded the closure and complication rates perioperatively and during a 12-month follow-up period. Complete closure was achieved in 8 patients; 2 patients had persistent trivial residual shunts. No deaths, conduction block, device embolism, or other complications occurred throughout the study period.We conclude that perventricular device closure is a safe, effective salvage treatment for postoperative residual muscular ventricular septal defects in pediatric patients. Long-term studies with larger cohorts might further confirm this method''s feasibility.Key words: Cardiac surgical procedures/instrumentation/methods, equipment design, heart defects, congenital/adverse effects, heart septal defects, ventricular/complications/pathology/therapy, hemodynamics, postoperative complications, prostheses and implants, surgical procedures, minimally invasive/methods, treatment outcomeMuscular ventricular septal defects (VSDs) constitute approximately 20% of all VSDs1 and are possibly associated with other complex congenital heart conditions, such as tetralogy of Fallot and double-outlet right ventricle.2 Surgical closure is the mainstay treatment for most VSDs; however, muscular VSDs cannot be approached adequately without a ventricular incision, especially when associated with a large left-to-right shunt, pulmonary hypertension, or interventricular septal hypertrophy.3–5 After complex congenital heart defects with severe left-to-right shunting are repaired, residual muscular VSDs can significantly increase the patient''s risk of death.4,5
Particularly in pediatric patients, postoperative residual muscular VSD poses a surgical challenge. Open surgical repair is associated with repeat cardiopulmonary bypass (CPB), the risk of ventriculotomy because of an inadequate operative field of vision, and postoperative ventricular dysfunction.5,6 Fluoroscopically guided transcatheter device closure is another treatment option; however, restricted vascular access and the technical difficulty of this procedure are well documented in pediatric patients. Radiation exposure and hemodynamic instability during device positioning can also compromise the prognosis.2,7
Perventricular device closure of VSDs with transesophageal echocardiographic (TEE) guidance was first reported by Amin and colleagues.8 This method enables direct access, which is especially suitable in closing apical muscular VSDs.9 We investigated the feasibility of perventricular device closure as a salvage procedure in pediatric patients who had residual muscular VSDs after having undergone repair of complex congenital heart defects. 相似文献

Ventricular septal defect is the most common congenital heart malformation. Surgical closure, when indicated, has been practiced for over 50 years with good results; however, surgical closure is still associated with significant morbidity and mortality. Over the past decade, several occluding devices have been developed that made catheter device closure an attractive alternative to surgery with widely satisfactory results. In this article, a comprehensive review of percutaneous and perventricular (hybrid) device closure of each type of ventricular septal defect is presented. 相似文献

Postinfarction ventricular septal defect remains an important complication for myocardial infarction. It is associated with high mortality and morbidity. Despite early surgical closure attempts, mortality remains about 19–49%. Percutaneous approach, especially in high surgical risk patients is a promising alternative to traditional surgical closure, thus avoiding the deleterious effects of cardiopulmonary bypass and the ventriculotomy. The Amplatzer P.I. Ventricular Septal Defect Occluder is a device specifically designed to percutaneously close these defects in adult patients. The results reported using this device are comparable (if not better) to those for surgical closure. Here, we review the experience using this device and depict in detail the technical aspects of the procedure. 相似文献
