摘　　要：目的 探讨三尖瓣游离壁起源室性早搏的标测与消融策略。方法 将起源于三尖瓣游离壁的室性早搏,采用Carto3三维电解剖标测系统和长鞘支持,标测消融导管经股静脉途径至三尖瓣下,采用反U方式标测和消融。结果 19例起源于三尖瓣游离壁室性早搏患者标测消融导管采用反U法,于三尖瓣游离壁瓣下进行标测消融,即刻均获成功,无并发症发生,6个月随访1例患者室性早搏复发。结论 三尖瓣环游离壁起源室性早搏术前可通过体表心电图特点做出大致定位判断,采用反U法标测和消融简单、安全、疗效可靠。Objective to investigate the mapping and ablation strategy of premature ventricular contraction(PVC) originating from the free wall of tricuspid annulus.Methods With the Carto3 three-dimensional electro-anatomical mapping system and long sheath supporting, the PVC originating from the free wall of the tricuspid annulus was mapped and ablated by inverted U-shaped catheter via the femoral vein access.Results In 19 patients with PVC originating from the free wall of the tricuspid annulus, mapping and ablation with an inverted U-shaped catheter under the free wall of tricuspid annulus was carried out.The treatment was immediately successful in all the 19 patients, and no complications occurred.During the 6-month follow-up period, one patient developed recurrence of PVC.ConclusionThe PVC originating from the free wall of the tricuspid annulus can be roughly judged by the features of the electrocardiogram of the body surface before operation, and the mapping and ablation treatment by using inverted U-shaped catheter is technically-simple and clinically-safe with reliable therapeutic efficacy.
