摘要
目的探讨导管法消融右室流出道室性早搏伴左心室增大患者的疗效。方法对30例右室流出道室性早搏伴左心室增大的患者进行导管法射频消融(Radiofrequency cathter ablation,RFCA)治疗。术前常规完成心脏超声检查,成功消融术后5年每年随访超声心动图(ultrasound echocardiography,UCG)及动态心电图(Dynamic Electrocardiogram,DCG,又称Hol-ter)。结果 30例患者即刻成功者20例,远期成功8例,无效者2例。术后1年随访20例即刻成功者,UCG结果提示18例患者左室舒张末期内径已在正常值范围内,与自身相比缩小值在3～7 mm以上;随访至第2、3、4、5年,UCG结果无明显变化。另2例患者心脏大小虽未达到正常值范围,但与自身相比较亦有相应缩小。8例远期成功者临床症状也有明显改善。结论导管法消融治疗右室流出道室早伴左心室增大具有良好临床疗效。
Objective To investigate the therapeutic efficacy of catheter ablation in treatment of patients with premature ven- tricular complexes originating from the right ventricular outflow tract accompanied with left ventricular enlargement. Methods The catheter ablation was performed to 30 patients selected. The routine cardiac ultrasound examination was carried out before operation. Af- ter surgery, the patients were followed-up for 5 years. During the period of follow-up, echocardiography and dynamic electrocardiogram DCG （Holter） monitoring were performed every year. Results In the 30 patients,20 were acute success, 8 were effective, and 2 were in- effective. At the first year follow-up, the UCG results showed that 18 of 20 acute success patients presented a normal left ventricular end- diastolic diameter,and at least reduced 3 ~ 7 mm compared to pre-operation. During the periods of 2 -5 years follow-up, no further changes were observed. The heart size of another 2 acute success patients was also reduced although not reach to the normal range. The clinical symptoms of 8 effective cases were also significantly improved. Conclusions The catheter ablation is clinical efficacy in the treatment of ventricular premature right ventricular outflow tract with left ventricular enlargement.
