Between October 1997 and May 1998 a newly developed thinner (8 French) intra aortic balloon (IAB) catheter (Datascope®) was evaluated in 22 patients. Differences to known IAB systems are as follows: Reduction of the diameter to 8 French at a constant balloon volume of (40 cc); modification of the transition between catheter and balloon; radiolucent stripe in the catheter and a new flexible Nitinol coated guidewire.
All 22 patients required IAB support after coronary artery bypass grafting (CABG) for low-output-syndrom. Recipient age was 67 ± 7 years (range 50 to 77), 32% were female, body mass index was 26 ± 3. Preoperative ejection fraction (EF) was 40% ± 16.
Intra-aortic balloon catheter insertion was performed percutaneously in all 22 patients in 17 patients (77%) without and in 4 patients (19%) with sheath.
Due to severe peripheral arterial occlusive in one patient the IAB was implanted directly via a vascular graft to the ascending aorta.
Duration of IAB support was 61 ± 53 hours. There were neither limb ischemia, dissections, perforations of the artery nor severe bleeding in these patients.
In conclusion a thinner IAB catheter may be useful in reducing the incidence of limb ischemia complications. The new 8 French IAB is safe and thus a reliable alternative to conventional systems in patients. Further randomized trials have to be performed.
