Driveline infections in left ventricular assist devices-Incidence, epidemiology, and staging proposal.

BACKGROUND: Driveline infections (DLI) are a serious complication in patients with left ventricular assist devices (LVAD). Apart from the differentiation between superficial and deep DLI, there is no consensus on the classification of the severity of DLI. Little is known about risk factors and typical bacteria causing DLI in centrifugal-flow LVADs. METHODS: In this single-center study with 245 patients, DLI were classified by their local appearance using a modification of a score suggested by the Sharp Memorial group. The driveline exit site was inspected routinely every 6 months. RESULTS: Severe DLI were detected in 34 patients (15%) after 6 months and in 24 patients (22%) after 24 months. The proportion of patients with DLI increased significantly during the follow-up (p = 0.0096). The most common bacteria in local smears were Corynebacterium, coagulase-negative Staphylococcus, and Staphylococcus aureus. Fifty-nine patients were hospitalized more than once for DLI. In these patients, S. aureus was the most common bacterium. It was also the most common bacterium in blood cultures. Higher BMI, no partnership, and a HeartMate 3 device were identified as risk factors for DLI in a multivariable cause-specific Cox regression. CONCLUSION: This study is a standardized analysis of DLI in a large cohort with centrifugal-flow LVADs.

Absorbable antibiotic beads for treatment of LVAD driveline infections.

BACKGOUND: Infections of the left ventricular assist device (LVAD) driveline are a dreaded complication that results in high mortality and morbidity. METHOD: We retrospectively reviewed five consecutive patients with severe continuous-flow LVAD (HVAD, Heartmate 2, and Heartmate 3) driveline infection. These infections, which developed on an average of 960.4 ± 843.9 days after LVAD placement, were refractory to systemic antibiotics and local wound care. All were treated with extensive surgical debridement, local installation of absorbable antibiotic-loaded calcium sulfate beads (vancomycin and tobramycin), primary wound closure, and 6 weeks of systemic antibiotics after surgery. RESULTS: Four patients had resolution of DLI, and one had a recurrent infection at another part of the driveline 7 months after the complete resolution of the previous site. This patient was successfully treated with debridement and bead placements. Three patients still have their LVADs, while two received orthotopic heart transplants. At the time of the transplant, there was no evidence of gross infection of the LVAD drivelines or pumps. At the average follow-up time of 425.8 ± 151 days, no patients have an active infection. CONCLUSION: Treatment of LVAD driveline infection with absorbable antibiotic beads with primary wound closure is a viable option and merits further investigation.

HFSA Expert Consensus Statement on the Medical Management of Patients on Durable Mechanical Circulatory Support.

The medical management of patients supported with durable continuous flow left ventricular assist device (LVAD) support encompasses pharmacological therapies administered in the preoperative, intraoperative, postoperative, and chronic LVAD support stages. As patients live longer on LVAD support, the risks of LVAD-related complications and progression of cardiovascular and other diseases increase. Using existing data from cohort studies, registries, randomized trials, and expert opinion, this Heart Failure Society of America Consensus Document on the Medical Management of Patients on Durable Mechanical Circulatory Support offers best practices on the management of patients on durable mechanical circulatory support, focusing on pharmacological therapies administered to patients on continuous flow LVADs. Although quality data in the LVAD population are few, the use of guideline-directed heart failure medical therapies and the importance of blood pressure management, right ventricular preload and afterload optimization, and antiplatelet and anticoagulation regimens are discussed. Recommended pharmacological regimens used to mitigate or treat common complications encountered during LVAD support, including arrhythmias, vasoplegia, mucocutaneous bleeding, and infectious complications, are addressed. Finally, this document touches on important potential pharmacological interactions from antidepressants and herbal and nutritional supplements of relevance to providers of patients on LVAD support.

Experience with dalbavancin for long-term antimicrobial suppression of left ventricular assist device infections.

BACKGROUND: Left ventricular assist devices (LVAD) are a common strategy for management of end-stage heart failure. LVADs carry a risk of infection of the implanted device components, and skin flora are commonly implicated. Long-term antibiotics may be needed for management of deep device infection or recurrent superficial infections. In appropriately selected patients, dalbavancin can be a feasible option given its extended dosing interval. METHODS: This is a retrospective, single-center review of patients presenting with an LVAD infection between January 2011 and November 2022, where management included the use of dalbavancin. Data regarding LVAD placement, details of index infection, dalbavancin use and outcomes was obtained from chart review, and documented in a RedCap database. RESULTS: The mean time from LVAD placement to index infection was 131.6 weeks (standard deviation 87.2 weeks). The most common targeted organism was Corynebacterium striatum in six of 10 patients. Index infection presented as deep driveline infection in four patients and recurrent superficial driveline infection in three patients. Five patients had a concurrent bloodstream infection. Dalbavancin was discontinued in two patients due to breakthrough infection, with one patient requiring surgical intervention. No drug-related adverse events were noted. CONCLUSION: Dalbavancin is an attractive option in the management of long-term LVAD infection in patients for whom alternative oral or parenteral antibiotics are not a feasible option. Additional studies are needed to determine the optimal dosing of dalbavancin in this setting, and to study adverse events and long-term outcomes of dalbavancin.

Impact of an improved driveline management for HeartMate II and HeartMate 3 left ventricular assist devices.

BACKGROUND: We evaluated the impact of a standardized driveline care strategy, including a subfascial-tunneling method and dressing protocol, on the incidence of driveline infection (DLI). METHODS: DLI data from all HeartMate II (HMII) and HeartMate 3 (HM3) patients (including exchange devices) were retrospectively collected between 2013 and 2021. The driveline subfascial-tunneling method was altered in three steps (A: right direct; B: left triple, C: right triple), and the shower protocol was changed in two steps (A: with/without cover, B: with cover). Disinfection was individually tailored after changing the shower protocol. Complications associated with morbidity and mortality were evaluated for each modification. RESULTS: During the study period, 80 devices were implanted (HMII, n = 54; HM3, n = 26). The 8-year incidence of DLI was 15% (n = 8) in HMII patients and 0% in HM3 patients (p = 0.039). DLI was not associated with hospital mortality. The modified dressing protocol and tunneling method was associated with a significantly better DLI incidence rate in comparison to the previous one: Protocol-A (n = 17), Protocol-B (n = 63), 35% vs 3% (p = 0.0009), Method-A (n = 13), Method-B (n = 42), Method-C (n = 25), 46% vs 5% vs 0% (p = 0.0001). The rete of freedom form DLI at 1, 2, and 3 years had also significant difference between groups: Protocol-A and Protocol-B, 80%, 54%, 54% vs 96%, 96%, 96%, respectively (p < 0.0001), Method-A, Method-B and Method-C, 76%, 44%, 44%, vs 94%, 94%, 94% vs 100%, 100%, respectively (p < 0.0001). CONCLUSIONS: A standardized triple driveline tunneling strategy and waterproof dressing protocol reduced driveline infection in HM3 patients to 0%.

Prophylactic negative pressure wound therapy is not effective for preventing driveline infection following left ventricular assist device implantation.

BACKGROUND: Driveline infection (DLI) following left ventricular assist device (LVAD) implantation remains an unresolved problem. Negative pressure wound therapy (NPWT) promotes wound healing by applying negative pressure on the surface of the wound. Recently, the prophylactic application of NPWT to closed surgical incisions has decreased surgical site infections in various postsurgical settings. Therefore, we evaluated the efficacy and safety of prophylactic NPWT for preventing DLI in patients with LVAD implantation. METHODS: Prophylactic NPWT was provided to 50 patients who received continuous-flow LVADs as bridge-to-transplant therapy at our institution between May 2018 and October 2020 (NPWT group). The negative pressure dressing was applied immediately after surgery and retained on the driveline exit site for 7 days with a continuous application of -125 mm Hg negative pressure. The primary outcome was DLI within 1 year of LVAD implantation. We compared the rate of DLI incidence in the NPWT group with that in the historical control cohort (50 patients) treated with the standard dressing (SD) who received LVAD implantation between July 2015 and April 2018 (SD group). RESULTS: No severe complications were associated with the NPWT. During the follow-up period, DLI was diagnosed in 16 participants (32%) in the NPWT group and 21 participants (42%) in the SD group. The rates of DLI incidence and freedom from DLI did not differ between groups (p = 0.30 and p = 0.63). CONCLUSIONS: Prophylactic NPWT at the driveline exit site was safe following LVAD implantation. However, it did not significantly reduce the risk of DLI.

Preventing driveline infection during left ventricular assist device support by the HeartMate 3: A survey-based study.

PURPOSE: Driveline infection (DLI) is a significant source of morbidity and mortality during left ventricular assist device (LVAD) support yet limited studies are available to describe the center-level prevalence, preventive practices, and their potential effectiveness. METHODS: We surveyed LVAD centers in the United States to determine program burden and preventive practices for DLI during HeartMate (HM) 3 support. An online, anonymous, question-based survey was sent to expert providers at implanting centers. Only a single respondent completed the survey for each center. As an exploratory analysis, we compared specific DLI preventive practices between centers with low (≤10%) and high (>10%) reported prevalence of DLI. RESULTS: Seventy-eight centers responded to the survey (response rate: 50%). Respondents were comprised of 37 (47%) heart failure cardiologists, 27 (35%) LVAD coordinators, and 14 (18%) cardiothoracic surgeons. The prevalence of DLI during HM3 was reported as ≤10% by 27 (35%), 11%-25% by 36 (46%), and >25% by 16 (19%) centers. Thirteen (17%) centers had a body mass index threshold for device placement, 29 (37%) utilized a counter incision, 66 (81%) placed an anchor stitch, and 69 (88%) used an external device to stabilize the DL. Proportionally, more centers with a low DLI prevalence used a wound vacuum 6 (22%) versus 3 (6%, p = 0.03) than those with high DLI. CONCLUSION: Variation exists in reported prevalence and practices of preventing and managing driveline infections across centers during HM3 support. Further studies are warranted to develop and assess the effectiveness of standardized preventive strategies.

Epidemiology of Left Ventricular Assist Device Infections: Findings From a Large Nonregistry Cohort.

BACKGROUND: Infection is a major complication during circulatory support with a left ventricular assist device (VAD). Changes in device characteristics and treatment practices in the last decade can affect the epidemiology of infection. The International Society for Heart and Lung Transplantation (ISHLT) has published recommendations on the prevention and management of VAD infections, but data to support these recommendations remain sparse. METHODS: We performed a retrospective review of 455 patients who underwent VAD placement from 2009 to 2015. Infection episodes were defined using ISHLT criteria and were also grouped as endovascular or local. Analysis included descriptive statistics. RESULTS: There were 174 patients (38.6%) with a VAD infection. Infection incidence was 36.9 cases per 100 person-years of VAD support. The driveline was the most common infection site (67.2%). Systemic inflammatory response syndrome (SIRS) criteria were not satisfied in 29.2% of patients with endovascular infections, and computed tomography (CT) examinations were normal in 37.7% of cases. Gram-positive bacteria caused 65.6% of infections in patients with an available culture. Antimicrobial suppression was used in 72.3% of patients who survived treatment. Median survival after infection was 35 months for patients with VAD-related infections versus 14 months for patients with VAD-specific infections. CONCLUSIONS: VAD infections continue to be a major complication after implantation. Clinical criteria alone were not predictive of serious infections, and many patients with confirmed infection had normal CTs. Patients with VAD-specific infections had lower median survival than patients with VAD-related infections.

Left ventricular assist device driveline infections in three contemporary devices.

Driveline infections (DLI) are common adverse events in left ventricular assist devices (LVADs), leading to severe complications and readmissions. The study aims to characterize risk factors for DLI readmission 2 years postimplant. This single-center study included 183 LVAD patients (43 HeartMate II [HMII], 29 HeartMate 3 [HM3], 111 HVAD) following hospital discharge between 2013 and 2017. Demographics, clinical parameters, and outcomes were retrospectively analyzed and 12.6% of patients were readmitted for DLI, 14.8% experienced DLI but were treated in the outpatient setting, and 72.7% had no DLI. Mean C-reactive protein (CRP), leukocytes and fibrinogen were higher in patients with DLI readmission (P < .02) than in outpatient DLI and patients without DLI, as early as 60 days before readmission. Freedom from DLI readmission was comparable for HMII and HVAD (98% vs. 87%; HR, 4.52; 95% CI, 0.58-35.02; P = .15) but significantly lower for HM3 (72%; HR, 10.82; 95% CI, 1.26-92.68; P = .03). DLI (HR, 1.001; 95% CI, 0.999-1.002; P = .16) or device type had no effect on mortality. DLI readmission remains a serious problem following LVAD implantation, where CRP, leukocytes, and fibrinogen might serve as risk factors already 60 days before. HM3 patients had a higher risk for DLI readmissions compared to HVAD or HMII, possibly because of device-specific driveline differences.

Driveline damage and repair in continuous-flow left ventricular assist devices: A systematic review.

With mounting time on continuous-flow left ventricular assist device (CF-LVAD) support, patients occasionally sustain damage to the device driveline. Outcomes associated with external and internal driveline damage and repair are currently not well documented. We sought to evaluate the outcomes of driveline damage and its repair. Electronic search was performed to identify all relevant studies published over the past 20 years. Fifteen studies were selected for analysis comprising of 55 patients with CF-LVAD dysfunction due to driveline damage. Demographic and perioperative variables along with outcomes including survival rates were extracted and pooled for the systematic review. Most patients (53/55) were supported on HeartMate II LVAD (Abbott Laboratories, Abbott Park, IL). Internal damage was more commonly reported than external damage [69.1% (38/55) vs. 30.9% (17/55), P = .01]. Median time to driveline damage was 1.9 years [IQR 1.0, 2.5]. Most patients presented with a CF-LVAD alarm [94.5% (52/55)] and patients with internal driveline damage had a significantly higher rate of alarm activation compared to that observed for those with external damage [38/38 (100%) vs. 14/17 (82.4%), P = .04]. Patients with internal driveline dysfunction were more likely to experience component wear compared to those with external driveline dysfunction [10/38 (26.3%) vs. 0/17 (0%), P = .05]; 14.5% of patients (8/55) underwent external repair of the driveline, 5.5% (3/55) were treated with rescue tape, and 5.5% (3/55) were placed on an ungrounded cable, indicating a short-to-shield event had occurred. A total of 49.1% of patients (27/55) underwent CF-LVAD exchange, 5.5% (3/55) were weaned off the CF-LVAD to explant, and 5.5% (3/55) underwent emergent heart transplantation. The median length of hospital stay was 12 days [IQR 7, 12] and 30-day mortality rate was 14.5% (8/55). Driveline damage was more commonly reported at an internal location and despite being a well-recognized complication, mortality still appears high.

Complex HeartWare left ventricular assist device infection treated with pump exchange: clinical alert for the driveline location.

Infection is a major complication in patients with a left ventricular assist device (LVAD). Once a driveline exit-site infection (DLI) reaches the LVAD component, LVAD exchange may become necessary for radical treatment, although clinical results are not satisfactory. In this report, we describe two cases of LVAD infection successfully treated with pump exchange. During LVAD support, the DLI extended into the pump pocket and the outflow graft despite aggressive surgical debridement and negative pressure wound therapy. These two patients required LVAD exchange for radical treatment, because the estimated waiting period for heart transplantation was at least more than 1 year. The LVAD exchange was performed through median re-sternotomy, and the infected HeartWare ventricular assist device (HVAD) was completely removed under cardiopulmonary bypass. Then, a new LVAD covered with the omentum flap was implanted. These two patients were successfully bridged to heart transplantation after 10 months and 2 years of support without recurrence of infection. These two cases may suggest that the driveline of the HVAD needs to be kept away from the outflow graft to prevent refractory outflow graft infection.

Efficacy and safety of chronic antimicrobial suppression therapy for left ventricular assist device driveline infections: A single-center descriptive experience.

BACKGROUND: Driveline infection (DLI) is the most common left ventricular assist device (LVAD) infectious complication. Short-term antimicrobial therapy and local debridement are the cornerstones of management for these infections, but the use of chronic antimicrobial suppression (CAS) therapy is not well characterized. METHODS: To better characterize the efficacy of CAS therapy, we performed a retrospective review of all patients (N = 219) receiving care at our tertiary transplant center with continuous-flow LVADs placed between August 2007 and July 2019. RESULTS: A total of 24 patients were identified as having received CAS therapy as treatment for DLIs. The mean age was 56 years, 50% were female, and chronic kidney disease affected 63% of patients. Staphylococcus aureus accounted for half of all initial DLIs, and the mean length of CAS therapy was 486 days (range 48-2287 days). All patients received per os regimens as suppression therapy. Adverse events impacted 5 of 24 patients (0.43 events per 1000 days). Overall, the use of CAS therapy led to successful outcomes in 50% of patients and 29% experienced treatment failures. The remaining patients experienced stable symptoms. Relapses were the most common cause of treatment failure, and three patients experienced reinfections while on CAS therapy. CONCLUSIONS: Our study suggests that CAS therapy for DLIs can be well tolerated, and future studies are needed to determine which patients merit suppression.

Absorbable antibiotic beads as an adjuvant therapy in treating ventricular assist devices driveline infection: A case report.

BACKGROUND: Ventricular assist devices driveline infections are common, recalcitrant, and carry high morbidity and mortality. Herein, we reported a patient with driveline infection that was successfully treated with a combination of systemic antibiotics, surgical debridement, and instillation of absorbable antibiotic beads to the wound bed. METHODS AND RESULTS: A 39-year-old man with nonischemic cardiomyopathy underwent insertion of a continuous flow left ventricular assist device. Four years postoperatively, the patient presented with clinical, laboratory, and radiologic signs of driveline tract infection. He underwent extensive surgical debridement, installation of absorbable antibiotic beads that consisted of calcium sulfate, vancomycin, and tobramycin, into the wound bed, and systemic antibiotics. The patient was free of infection 9 month postoperatively. CONCLUSION: Absorbable calcium sulfate antibiotic beads may serve as a beneficial adjunct to surgical debridement and systemic antibiotics for the treatment of ventricular assist device driveline infection, and merit further investigation.

Contemporary Management Strategies in VAD Infection.

PURPOSE OF REVIEW: The use of durable ventricular assist devices (VAD) to manage end-stage heart failure is increasing, but infection remains a leading cause of morbidity and mortality among patients with VAD. In this review, we synthesize recent data pertaining to the epidemiology, diagnosis, management, and prevention of VAD infections, discuss transplant considerations in patients with VAD infections, and highlight remaining knowledge gaps. We also present a conceptual framework for treating clinicians to approach these infections that draws on the same principles that guide the treatment of analogous infections that occur in patients without VAD. RECENT FINDINGS: Despite advances in device design, surgical techniques, and preventative interventions, more than a third of VAD recipients still experience infection as an adverse outcome. Positron emission tomography has emerged as a promising modality for identifying and characterizing VAD infections. High-quality data to support many of the routine therapeutic strategies currently used for VAD infections-including suppressive antibiotic therapy, surgical debridement/device exchange, and novel antimicrobials for emerging multidrug-resistant organisms-remain limited. Although pre-transplant VAD infection may impact some early transplant outcomes, transplantation remains a viable option for patients with most types of VAD infection. Standardized definitions of VAD infection applied to large registry datasets have yielded key insights into the epidemiology of infectious complications among VAD recipients, but more prospective studies are needed to evaluate the effectiveness of existing and novel diagnostic and therapeutic strategies.

New Treatment for Driveline Infection Following Implantation of a Ventricular Assist Device.

In patients with an implantable ventricular assist device (VAD), driveline infection (DLI) is a challenging complication. Once DLI occurs, it may lead to pump contamination and/or septicemia, which means that early treatment is essential. We hereby report our initial experiences of a mechanically-powered portable negative pressure wound therapy system (Smart Negative Pressure: SNaPTM) to treat DLI at an outpatient clinic.

Role of Gallium-SPECT-CT in the Management of Patients With Ventricular Assist Device-Specific Percutaneous Driveline Infection.

BACKGROUND: Percutaneous driveline infection is a major complication of left ventricular assist device (LVAD). This study evaluated the role of gallium-67 single-photon emission computed tomography (Ga-SPECT)-CT in LVAD-specific percutaneous driveline infection. METHODS: Thirty-six patients with implantable continuous-flow LVAD, who underwent Ga-SPECT-CT to evaluate percutaneous driveline infections, were enrolled and divided into uptake and no-uptake groups based on tracer concentration uptake on Ga-SPECT-CT. Primary outcomes were surgical intervention and readmission for driveline infection. RESULTS: Twenty-two patients had uptake on Ga-SPECT-CT. No significant differences were noted in patient characteristics, wound appearance, or laboratory results. The prevalence of positive skin culture at the driveline exit site (DLES), and usage and duration of antibiotics did not differ. However, the uptake group had higher 1-year event rates (surgical intervention: 39% vs 0%, P = .019; readmission: 74% vs 6.9%, P = .0016). In addition to positive skin culture at DLES and short duration of antibiotic therapy, uptake on Ga-SPECT-CT was a risk factor for surgical intervention (odds ratio 9.00; P = .018) and readmission (odds ratio 7.86; P = .0051). CONCLUSIONS: Ga-SPECT-CT could be one of the clinical modalities for guiding the treatment of driveline infection in patients with a LVAD.

Ventricular assist device-related infections and solid organ transplantation-Guidelines from the American Society of Transplantation Infectious Diseases Community of Practice.

The Infectious Diseases Community of Practice of the American Society of Transplantation has published evidenced-based guidelines on the prevention and management of infectious complications in SOT recipients since 2004. This updated guideline reviews the epidemiology of ventricular assist device (VAD) infections and provides recommendations for the management and prevention of these infections. Almost one half of those awaiting heart transplantation are supported with VADs. Despite advances in device technologies, VAD infections commonly complicate mechanical circulatory support and remain typified by common components and anatomic locations. These infections have important implications for transplant candidates, most notably increased wait-list mortality. Strategic management of these infections is crucial for successful transplantation. Coincidentally, explantation of all VAD components at the time of transplantation is often the definitive cure for the device-associated infection. Highlighted in this updated guideline is the reported success of transplantation in patients with a variety of pre-existing VAD infections and guidance on post-transplant management strategies.

Driveline angle is crucial for preventing driveline infection in patients with HeartMate II device.

We hypothesized that the externalizing direction of the driveline (the driveline angle) at the percutaneous exit site would influence the occurrence of driveline infection after left ventricular assist device implantation. From August 2013 to May 2017, 71 patients were implanted with a HeartMate II device in our center. The driveline angle was measured on anteroposterior radiography just after implantation. Risk factors for driveline infection were analyzed by uni- and multivariate analyses. Driveline infection developed in 10 (14%) patients during follow-up. Overall actual freedoms from driveline infection at 6, 12, and 24 months were 96%, 88%, and 86%, respectively. Overall number of driveline infection events per patient-year was 0.16. Receiver operating characteristic analysis determined the cut-off point of the driveline angle as 41°. The 6-, 12-, and 24-month actuarial freedoms from driveline infection in those with driveline angle more than 42° (84%, 74%, and 74%, respectively) were significantly lower than in those with driveline angle less than 41° (97%, 94%, and 90%, respectively; p < 0.02). The numbers of driveline infection events per patient-year were 0.16 in patients with driveline angle more than 42°, and 0.04 in patients with driveline angle less than 41°. Multivariate analysis demonstrated that driveline angle more than 42° was an independent risk factor for driveline infection (hazard ratio 4.71). Driveline angle more than 42° is an independent risk factor for driveline infection in patients with HeartMate II. Externalization of the driveline toward the horizontal direction is important to prevent driveline infection with HeartMate II.

[Driveline Wound Care: Key to the Long-Term Use of Implantable Ventricular Assist Devices].

Heart failure is a complicated chronic disease. Although numerous new medications are used to treat and improve the quality of life of patients with heart failure, the final treatment for terminal heart failure still relies heavily on heart transplants. However, as the number of heart donations is limited, many health institutions implant mechanical assist devices to perform heart functions temporarily. These implanted ventricular assist devices help reduce heart failure symptoms and enhance quality of life. However, driveline infection is one of the more severe complications associated with these devices. If this infection is not controlled, another heart surgery will be necessary to replace the device. Severe driveline infection may even lead to patient death. An approach to care that includes driveline wound care standardization and immobilization of the driveline has been shown to effectively decrease the incidence of driveline infections and to increase the survival rate. As Taiwan still lacks the relevant clinical care standards for implantable ventricular assist device support and driveline wound care, this study introduces the relevant Western literature and the author's clinical experience related to driveline wound management. We hope that this article serves as a useful reference for related nursing care.

Substantial Reduction in Driveline Infection Rates With the Modification of Driveline Dressing Protocol.

BACKGROUND: Driveline infection (DLI) is a cause of morbidity and mortality in patients with continuous-flow left ventricular assist devices (CF-LVADs). We hypothesized that an alternate dressing protocol would decrease the rate of DLIs. METHODS AND RESULTS: A retrospective review of CF-LVAD implants at a single institution from January 2010 to October 2015 was conducted. Patients were divided into implants before (group 1) and after (group 2) the introduction of the new protocol on September 1, 2012. Patients were followed until death, transplantation, change in dressing type, or 2 years. 153 patients were included: 61 in group 1 and 92 in group 2. Group 1 had fewer HVADs than group 2 (27.9% vs 71.7%; P < .001) and more destination therapy, although the latter was not statistically significant (50.8% vs 34.8%; P = .118). At 24 months, the freedom from DLI was 53% in group 1 and 89% in group 2 (P = .01). Group 1 had a significantly greater risk of DLI than group 2 (incident rate ratio 3.18, 95% confidence interval 1.23-8.18; P = .016). CONCLUSIONS: Dramatic improvement in freedom from DLI at 2 years was achieved with a new driveline dressing protocol. This demonstrates that DLI rates can be improved with alternate percutaneous site care techniques in CF-LVAD patients.
