ventricular outflow tract

Objective To evaluate the condition of right ventricular outflow tract ( RVOT) during perioperative period by transesophageal echocardiography ( TEE) in children with tetralogy of Fallot ( TOF).

目的运用经食管超声心动图（TEE）对儿童法洛四联症（TOF）的右室流出道（RVOT）情况进行围术期评价。

Objective To compare the difference of effect while using homograft pericardium patch and Gore-tex patch in staged repair of tetralogy of Fallot ( TOF) to enlarge the right ventricular outflow tract ( RVOT).

目的比较人同种心包补片和Gore-tex补片在法洛四联症（Tetralogy of Fallot，TOF）分期手术中扩大右心室流出道（right ventricular outflow tract，RVOT）的效果。

Other 28 patients underwent TASH successfully. Just after operations and 7 days, left ventricular outflow tract pressure gradient decreased at no less than 50%.

余28例均成功消融，术后即刻及术后7d，左室流出道压力阶差下降≥50%。

Objective To explore the clinical application of spiral electrode wire in the right ventricular outflow tract ( RVOT) pace-making and its therapeutic effect.

目的探讨右室流出道起搏螺旋电极导线的临床应用疗效。

Conclusion DSAS is a progressive disease, Better knowledge of pathological anatomy, timing of surgery, the key to the operation is that left ventricular outflow tract should be thoroughly dredged, no injury should be made to the aortic valve, mitral valve and conduction bundle.

结论局限性主动脉瓣下狭窄是进展性的疾病，需掌握该病的病理解剖和手术适应症，手术关键是彻底解除狭窄，同时防止对主动脉瓣、二尖瓣及传导束的损伤。
