Abstract

Background: We analyzed patients with left ventricular assist device (LVAD) related and specific infection, and aimed to determine whether surgical technique implantation affect the frequency of infection. Methods: We retrospectively analyzed the data of 99 patients who received LVAD at our department between June 2013 and June 2019. Patients were divided into two groups according to the surgical technique. Group A ( n = 58) was conventional sternotomy (CS) and group B ( n = 41) was on-pump minimally invasive left thoracotomy (MILT). Demographics, preoperative risk factors, LVAD infections, surgical incision site, driveline site, and outcomes were compared between these two groups. Results: Mean follow up time was 589 ± 480 (31–2171) days. Infection was detected in 34% (41/99) of LVAD patients. Admission to emergency department and intensive care unit (ICU) in last 6 months were significantly higher in MILT group. There was no difference between the two groups in terms of driveline exit site infection (CS: 28%, MILT: 27%) ( p > 0.05). Seven (17%) patients had infection in the thoracotomy incision site area in the MILT group. The rate of ICU hospitalization in the last 6 months was seen as the only independent risk factor increasing the frequency of infection (R = 0.30; p = 0.016). Survival analysis at 60 days, 1 year and 2 years showed no difference between the two groups ( p = 0.09). Conclusions: Despite advances in pump technology and surgical technique, infection is still an important cause of mortality and morbidity.
