Introduction: A growing number of patients are implanted with a continuous-flow left ventricular assist device (CF-LVAD) for destination therapy (DT). Hypothesis: We sought to determine if indication for DT was associated with adverse events and survival. Methods: Between May 2004 and May 2014, 211 patients (age 66 (19-82), 89% male) underwent implantation of a HeartMate II CF-LVAD. The cohort was stratified according to primary listed indication for DT at time of implant: Group 1=advanced age (n=124, 59%); Group 2=high BMI (n=33, 16%), and Group 3=end-organ comorbidities (n=54, 25%). DT patients who later became BTT were eliminated for homogeneity. Results: Follow-up was available in all patients for a total of 376 patient-years of support (median 1.4 years). Preoperative characteristics (creatinine 1.5, INTERMACS 3, IABP 49%) were comparable between groups (all p>0.05). Overall 1, 3 and 5-year survival was 81%, 58%, and 41%, respectively. Kaplan-Meier analysis revealed comparable survival between groups stratified by DT indications (Figure, p=0.07). While gastrointestinal (GI) bleeding was more frequent in patients implanted for advanced age DT indications (p=0.01, group 1 vs group 2 and 3), the incidence of adverse events (pump thrombus/exchange, stroke) was comparable between groups. After adjusting for covariates (creatinine, hemoglobin, prior sternotomy and diabetes), Cox regression analysis demonstrated only preoperative renal dysfunction (HR 1.86 CI 1.28, 2.69; p=0.001) and lower Hemoglobin (HR 0.82 CI 0.71, 0.95; p=0.008) were associated with late mortality after implantation. Conclusions: Advanced age remains the most frequent contemporary indication for DT in patients undergoing CF-LVAD implantation. Indication for DT implantation does not influence long-term survival. Elderly patients may be at greater risk of GI bleeding events. These results continue to favor a uniform selection process across the spectrum of DT indications.

Introduction: Frailty has recently been shown to be associated with increased risk of death after continuous-flow left ventricular assist device (CF-LVAD) implantation as destination therapy (DT), but no data exists specifically analyzing its association with specific early and late adverse events. Methods: Between February 2007 and May 2014, 251 patients (205 male) underwent primary implantation of CF-LVAD at our institution; 157 (63%) were implanted as DT and preoperative frailty assessment was available in 96 pt. Frailty was identified in 58/96 (60%) patients according to the deficit index (31 impairments, disabilities and comorbidities) and defined as > 25% deficits. Age (67 vs. 64 years, p=0.12), male sex (79% vs. 87%, 0.63), chronic kidney disease (64% vs. 63%, p=0.74), creatinine (1.7 vs. 1.5, p=0.1), hemoglobin (11.6 vs. 11.5, p=0.98), and albumin levels (3.7 vs. 3.8, p=0.53) were similar between frail and non-frail pt, while diabetes (59% vs. 13%, p<0.001), ischemic etiology (64% vs. 45%, p=0.04), and preop balloon pump (50% vs. 26%, p=0.01) were significantly different. Results: All patients underwent CF-LVAD implantation and cardiopulmonary bypass time was similar between groups (102 vs. 111 min., p=0.3). There were no significant differences in early adverse events between frail and non-frail pt, including inotrope duration (120 vs. 96 hr., p=0.11), right ventricular failure (19% vs. 13%, p=0.44), respiratory failure (26% vs. 18%, p=0.34), acute renal failure (16% vs. 13%, p=0.69), and hepatic dysfunction (16% vs. 13%, p=0.69). Median length of stay (20 vs. 16 days, p=0.25) and early mortality (12% vs. 8%, p=0.48) were also similar. During a median follow up of 2 years with 224 patient/years of support, any GI bleed (43% vs. 42%, p=0.79), any thromboembolic event (34% vs. 39%, p=0.74), and driveline infection (10% vs. 26%, p=0.052). Conclusions: In this select cohort of patients, frailty did not portend higher risk of adverse events after CF-LVAD implantation for DT despite prior observation that late survival is reduced in these patients. These findings are extremely important in patient selection and counseling of patients prior to LVAD implantation.

Background: Tobacco smoking is a significant source of morbidity in patients with a durable left ventricular assist device. While various cessation strategies have been investigated, the ability of ventricular assist device centers to implement a successful tobacco cessation program remains uncertain. We explored various cessation strategies employed by ventricular assist device centers and assessed perspectives of their effectiveness, as well as institutional investment in these programs. Methods: A 37-question online self-report survey was created using Survey Monkey® and distributed worldwide. We investigated (1) programmatic strategies utilized for smoking cessation, (2) the respondent’s perspective on the effectiveness of these strategies, (3) the structure with which these therapies are administered, and (4) overall organizational support for these treatments. Results: A total of 47 centers worldwide completed the survey. The most common methods of tobacco cessation were pharmacologic and nicotine replacement therapy (78% and 66%). However, only about half (47% and 50%, respectively) of the centers indicated that these strategies were effective. When asked whether a respondent’s center perceives that tobacco smoking should be a deciding factor in destination therapy evaluations, nearly a third (15, 32%) responded in the affirmative. Conclusion: While significant overlap exists among centers regarding treatments used for smoking cessation with left ventricular assist device patients, the most common treatments are not thought to be effective. While the current recommendations require tobacco smoking cessation in only bridge-to-transplant patients and not destination therapy patients, a number of centers disagree with the national guidelines and believe smoking should be prohibited in both populations.
