biopsy proven liver fibrosis and outcomes in patients supported with a continuous-flow left...
TRANSCRIPT
groups we confirmed that results are optimal when elective LVAD
implantation is performed before development of inotropic depen-
dency or cardiogenic shock. These results suggest that age need not be
a limiting factor in the decision to implant MCS in end stage heart
failure.

Temporary RVAD Support after LVAD – Longterm OutcomeC.C.O. Oezpeker, M.M.S. Schoenbrodt, S.S.E. Ensminger,J.J.G. Gummert, M.M.M. Morshuis. Department of Thoracic andCardiovascular Surgery, Heart- and Diabetes Center NRW, RuhrUniversity Bochum, Bad Oeynhausen, North-Rhine Westphalia,Germany.
Purpose: Right heart failure after LVAD implantation can still be a
significant problem in patients with moderate reduced right ventricular
function. The aim of this study was to analyse the outcome of 42
patients with temporary centrimac RVAD support.
Methods and Materials: From September 2004 until March 2012 281
LVADs were implanted at our center. Out of this cohort, 42 patients
14.9 % (gender: male n ¼33; female n¼9 Age: 53.6 � 13.8 years)
needed temporary RVAD support with Centrimag. The mean
supporting time was 36.2 days (min. 1 / max. 183 days). The following
LVADs were used in this patient cohort: HW (18), HMII (16), DH (2),
Ventras (2), Novacor (2), HeartAs (1) and CorAid (1). Cannulation
was performed via right atrium/ pulmonary artery (22), pulmonary
artery / femoral vein (14) and femoral artery/vein (4). In 27 patients an
Oxygenator was also required. Clinical outcomes of the patients
were assessed with respect to survival, successful weaning and major
complications such as bleeding or ischemia and neurological events
were analysed.
Results: Out of 42 patients, 8 patients were weaned successfully and
discharged home. 5 patients initially successfully weaned expired
during follow up as a consequence of complications such as sepsis and
MOF under LVAD support. In addition, 4 patients were directly
bridged to heart transplantation. However, in 3 patients weaning was
not possible and these were bridged to longterm RVAD- HeartWare
(1) and TT (2) support. 22 patients expired under combined LVAD/
RVAD support. Reason for death included MOF (10), MOF and
sepsis (7), sepsis (1) and intracerebral bleeding (4). Additional pro-
blems were acute abdominal complications requiring surgery (3) and
one leg ischemia.
Conclusions: These data suggest that even patients suffering RV failure
after LVAD support can nowadays have an acceptable longterm
outcome.

Prolonged Mechanical Circulatory Support – 1000 Days with a LeftVentricular Assist DeviceC. Oezpeker, S. Oemer, M. Schoenbrodt, K. Hakim, L. Kizner,J. Boergermann, H. Milting, S. Ensminger, J. Gummert, M. Morshuis.Clinic for Thoracic and Cardiovascular Surgery, Ruhr-UniversityBochum, Heart & Diabetescenter NRW, Bad Oeynhausen, Germany.
Purpose: Ventricular assist devices (LVADs) are used for bridge to
heart transplantation (BTR) and long term destination therapy (DT)
for patients with end stage heart failure. Due to the growing number of
patients with terminal heart failure and a decrease in suitable donor
organs, timespans on mechanical circulatory support (MCS) of
patients are continuously increasing.
Methods and Materials: Since 2006 283 patients received LVAD
support with HeartMate II (HM2; n¼160), Duraheart (DUH; n¼74)
and Ventrassist (VA; n¼46). We analysed 34 patients (12.01%) who
were supported with a device for more than 1000 days. The patients
were divided into two groups, DT (n¼11: VA n¼5, HM2 n¼4, DUH
n¼2) and BTR (n¼22: HM2 n¼9; VA n¼7; DUH n¼6). Patients were
analysed retrospectively with regard to neurologic, infectious and
gastrointestinal complications.
Results: Mean duration of support of all patients was 1278 days. 7 out
of 34 patients, were succesfully transplanted, 4 died and 1 was
successfully weaned and 22 patients are still on support. Major
complications during support were driveline infections (n¼7), gastro-
intestinal bleedings (n¼7), technical failure (n¼6/cable breakage n¼4),
neurologic events (n¼6). First hospitilization after inital discharge
home was after 9.8 months, the mean frequency of hospitilizations
being 4.1 times. The overall mean duration of hospital stay was 65
days. Reasons for high urgency transplantation were neurologic
complications (n¼3; TIA,intracerebral bleeding, stroke), cable break-
age (n¼3) and hemolysis (n¼1). Five patients expired (min. 1063days/
max. 1392days) under support because of malignant tumors (n¼2), late
right heart failure (n¼1), intracerebral bleeding (n¼1) and one patient
becuase of primary graft failure post heart transplantation.
Conclusions: In the light of substantial donor organ shortage and the
growing number of heart failure patients prolonged MCS has become
a more frequent treatment modality. Here we show that this can be
achieved with acceptable longterm results.

Biopsy Proven Liver Fibrosis and Outcomes in Patients Supported with aContinuous-Flow Left Ventricular Assist DeviceS. Lee,1 M. Halkar,2 D. Nagpal,3 M. Bennett,1 N.N. Zein,4

Purpose: It is not clear whether patients with biopsy proven liver
fibrosis have worse outcomes following continuous-flow left ventri-
cular assist device (CF LVAD) implantation.
Methods and Materials: We retrospectively reviewed all patients in our
institution that had a liver biopsy prior to implantation of a CF
LVAD. Continuous variables were analyzed with Student’s T-test and
categorical variables were analyzed with Fischer’s Exact test.
Results: From June 2006 to August 2012, there were 14 patients that
had a liver biopsy prior to CF LVAD implant. The mean age of
patients was 55�10 years, 87% were male, and 47% had ischemic
cardiomyopathy. Indications for CF LVAD implant were destination
therapy (n¼5; 36%), bridge to transplant (n¼8; 57%) and bridge to
decision (n¼1; 7%). The patients were divided into two groups: those
with liver fibrosis grade 0 to 1 (Group A, n¼5) and those with liver
fibrosis grade41 (Group B, n¼9). Baseline demographics were similar
between the two groups. There were no significant differences in post-
operative renal failure requiring dialysis (p40.99), reoperation for
bleeding (p¼0.36), requirement of inotropes414 days post LVAD
implant (p¼0.5) or post operative hospital length of stay (LOS)
(p¼0.72). No patients in either group required RVAD implantation.
Post LVAD implant survival was 100% in both groups at 30 days and
was 100% and 78% at 1 year for group A and B respectively (p¼0.5).
Conclusions: In this single center retrospective review, patients with liver
biopsy proven4 stage 1 fibrosis have similar outcomes in terms of short
and mid-term survival, need for dialysis, reoperation for bleeding, post-
operative inotrope requirement and LOS compared to those with zero
or low grade liver fibrosis. No patients in either group required RVAD
support. These findings may have important implications in the selection
of LVAD candidates with liver dysfunction.
