经食道超声心动图在房间隔缺损封堵治疗中的应用

目的 :探讨经食道超声心动图(TEE)在引导Amplatzer封堵器堵闭房间隔缺损(ASD)术中的应用及价值。方法:应用TEE按Amplatzer封堵法适应症条件筛选6例中央型(II孔型)ASD患者,经TEE及X线引导进行封堵。结果:1例患者因合并肺动脉瓣狭窄,另1例因ASD缺损口距右房顶距离小于3mm而放弃封堵术,余4例成功进行了Amplatzer封堵术。所有病例TEE测量的ASD直径显著小于ASD最大伸展径[(18.6±1.8)mmvs(26.7±1.4)mm],术后即刻、24h、1个月行TTE检查,无残余分流及并发症。结论:TEE在ASD缺损介入治疗中占有极为重要的作用。     

超声评价外科封堵房间隔缺损

目的　评价经胸小切口外科介入封堵 孔型 ASD的疗效。　方法　术前用经胸及经食道超声心动图(TTE、TEE)筛选合适的病例 6人 ,术中用 TEE指导封堵 ,术后 1周、1月及 3月用 TTE观察封堵器的情况并测量各超声参数。　结果　 6例患者均封堵成功 ,仅 1例呈上下排列的二孔 ASD患者残留少量分流。所有患者术前术后左心大小均无增大 ,术后 3个月右心大小、肺动脉内径及肺动脉压基本恢复正常。　结论　超声心动图在术中监测安置以及术后疗效的评价方面起着非常重要的作用     

57例室间隔缺损的临床分析

分析影响先天性心脏病室间隔缺损纠治术的因素，以提高手术成功率。外科手术治疗５７例先天性心脏病室间隔缺损。手术死亡４例，无晚期死亡。严密修补室间隔缺损并防止损伤心传导束和主动脉瓣、彻底矫正合并畸形是手术成功的关键，但是肺动脉高压围术期的处理亦至关重要     

An unusual interatrial septum

The images focus on a very rare atrial septal anatomy known as "double atrial septum with persistent interatrial space.” Only scarce reports of this anomaly are found in literature. Due to increasing use of catheter-based interventions requiring a transseptal puncture, the recognition of this anomaly is essential for performing safe and effective procedures.     

Double‐Chambered Right Ventricle with Pulmonary Valve Endocarditis

We describe a rare case of pulmonary valve endocarditis associated with a double‐chambered right ventricle in an adolescent male highlighting the two‐dimensional and three‐dimensional transthoracic echocardiographic findings. He was managed with aggressive antibiotic therapy followed by surgery. The echocardiographic findings were confirmed during surgery.     

Correlation of anatomic and hemodynamic features with aortic valve leaflet deformity in doubly committed subarterial ventricular septal defect

Summary The records of 153 patients with doubly committed subarterial ventricular septal defect (DCVSD) who underwent intracardiac repair were analyzed to evaluate factors responsible for aortic valve leaflet deformity. The patients were divided into two groups according to their echocardiographic and angiographic features as well as anatomic findings at operation: DCVSD without (17/153, 11.1%) and with arterial valve offsetting (136/153, 88.9%). Aortic regurgitation (AR) was much more prevalent in the patients with (50.0%) than in those without leaflet deformity (2.2%,P < 0.01). Arterial valve offsetting is one of the major contributing factors to the development of leaflet deformity, accounting for 5.9% in the patients without offsetting and 46.3% in those with offsetting (P < 0.01). Among the patients with arterial valve offsetting, the pulmonary-to-systemic pressure ratio was significantly higher (P < 0.01) in the patients without (0.76 ± 0.14) than in those with leaflet deformity (0.36 ± 0.12), suggesting that pulmonary hypertension might prevent the aortic valve leaflet from prolapsing in DCVSD. In addition, increased severity of aortic valve leaflet deformity and subsequent AR were observed with increasing age. These results suggest that aging and the presence of arterial valve offsetting as well as the absence of pulmonary hypertension might be factors responsible for aortic valve leaflet deformity and subsequent AR in DCVSD. The anatomic and hemodynamic features in DCVSD have a great impact on the development of aortic valve leaflet deformity and subsequent AR.     

儿童先天性心脏病室间隔缺损致病因素分析

目的 :对儿童先天性室间隔缺损因素进行分析。方法 :报告 2 5 8例先天性室间隔缺损儿童 ,男性 14 4例 ,女性 114例 ,年龄 1～ 14岁。同时对 2 5 8例儿童的父母进行调查 ,调查对象为患先天性室间隔缺损儿童 ,儿童的父亲、母亲孕前和孕期多方面因素 ,将引起室间隔缺损的可能原因进行分析。结果 :发现家族中有遗传史 ,父母亲饮酒史 ,母孕期有感冒病史 ,母孕期服用抗病毒药物 ,父母孕期使用黄体酮及母孕期接触X射线 ,有较高先天性室间隔缺损的发病率。同时对患先天性室间隔缺损儿童血型分析 ,表明A型儿童和AB型儿童患先天性室间隔缺损频率较高 (分别为 4 2 2 5 %和 11 2 4 % )比值比(OR)分别为 1 6 3和 2 2 1。与对照组比较差异有显著性 (即A型 χ2 =7.0 2 ,P <0 0 0 1,AB型 χ2 =5 71,P <0 .0 5 )。A O ,AB O抗原患者组与对照组比较 ,OR分别为 1 72和 2 6 2 ,χ2 值分别为 6 72和 7 5 1均差异有显著性 (P <0 .0 0 1) ,而O型则相反患先天性室间隔缺损的机率相对减少。结论 :先天性室间隔缺损与家族遗传史、血型及父母孕期饮酒、服药等多方面因素有关。
