摘要
Objectives: CentriMag (R) (Abbott, Pleasanton, CA, USA) is indicated for temporary circulatory support for up to 30 days. Extended support is not uncommon, and the results vary considerably. Herein, we review our experience on extended support. Methods: We retrospectively analyzed 19 patients supported with CentriMag as a bridge to recovery, long-term ventricular assist device or transplantation from September 2011 to October 2021. Results: Nineteen patients (16 men and 3 women; mean age 51.7 +/- 9.2 years) had CentriMag left ventricular assist device (LVAD) implantation with the skirted-cannula technique. Twelve (63.2%), 6 (31.6%), and 1 (5.3%) patient were in INTERMACS 1, 2, and 3, respectively. The aims of support were bridge-to-decision in 3 patients (15.8%), and bridge-to-transplantation in 16 patients (84.2%). Fourteen patients were supported for longer than 30 days, while 5 patients had their CentriMag removed before 30 days. Of the 5 patients supported for less than 30 days, 3 died early after implantation due to complications of prolonged shock. The other 2 patients were successfully transplanted. Among the 14 patients supported for longer than 30 days, 1 patient died after transplantation and 13 patients survived either after transplantation or weaning off CentriMag. The overall 1-year survival rate was 73.7%. The duration of support for all patients ranged from 6 to 191 days (64 +/- 61 days; median 41 days). Conclusions: The skirted cannula technique for apical cannulation in implantation of CentriMag LVAD is an easy, safe and durable technique. Immediate post-operative and long-term complications are not common. Its use over 30 days is associated with acceptable survival.
