Usefulness of newly designed pigtail catheter with multiple side holes by reducing incidence of ventricular ectopy.
This study was designed to determine whether a newly designed 5 Fr pigtail catheter of Jet Balance with multiple side holes reduces the incidence of ventricular ectopy during left ventriculography. To examine the catheter movement in vitro, we injected a colored glycerin solution by an injector through 5 Fr Jet Balance catheter and 6 Fr conventional pigtail catheter suspended in a water filled, glass container. A recoil of the catheter caused by injection was observed for a 6 Fr conventional catheter; however, no catheter movement was observed when a 5 Fr Jet Balance was used. To evaluate clinical usefulness of the 5 Fr Jet Balance, we compared the number of incidence of ventricular ectopy during left ventriculography between 5 Fr Jet Balance and 6 Fr conventional pigtail catheters. In 104 consecutive patients who underwent left ventriculography, a 5 Fr Jet Balance was used in 55 patients (5 Fr Jet Balance group), and a 6 Fr conventional pigtail in 49 patients (6 Fr conventional pigtail group). The 5 Fr Jet Balance group had a significantly lower incidence of VPB (21.8% vs. 42.9%, P = 0.02), ventricular tachycardia (1.9% vs. 14.3%, P = 0.02), and multiple VPB (9.0% vs. 34.7%, P = 0.001), respectively, than the 6 Fr conventional pigtail group. In conclusion, a 5 Fr Jet Balance pigtail catheter is useful and safe as regard to the incidence of ventricular ectopy during left ventriculography. Cathet. Cardiovasc. Intervent. 48:220-225, 1999.
