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. 792 Temporary RVAD Support after LVAD – Longterm Outcome C.C.O.

Department of Thoracic and Cardiovascular Surgery, Heart- and Diabetes Center NRW, Ruhr University 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. 793 Prolonged Mechanical Circulatory Support – 1000 Days with a Left Ventricular Assist Device C. 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-University Bochum, 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. 794 Biopsy Proven Liver Fibrosis and Outcomes in Patients Supported with a Continuous-Flow Left Ventricular Assist Device S.

Starling. 1 1 Section of Heart Failure and Cardiac Transplant Medicine, Cleveland Clinic, Cleveland, OH; 2 Internal Medicine, Cleveland Clinic, Cleveland, OH; 3 Cardiothoracic Surgery, Cleveland Clinic, Cleveland, OH; 4 Digestive Disease Institute, Cleveland Clinic, Cleveland, OH. 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 5510 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 grade 41 (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 proven 4 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. 795 Home Discharge and Out-of-Hospital Follow-Up of Total Artificial Heart Patients Supported by a Portable Driver A.

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.

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.

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.
