- Abstract
Background: Use of continuous-flow left ventricular assist devices (LVAD) has increased over the years as a bridge to transplant. The HeartWare HVAD (Medtronic, Minneapolis, MN) and HeartMate III (HM3, Abbott, Abbott Park, IL) are currently approved centrifugal-flow devices used for bridge to transplant. We sought to evaluate outcomes of the patients listed and who received a transplant after receiving these 2 devices., Methods: The United Network of Organ Sharing thoracic transplant database was queried after August 23, 2017, until December 2018 to identify patients aged older than 18 years listed for heart transplant and supported by the HVAD or HM3. Patient characteristics were evaluated at the time of listing and transplant. The primary study end point was 1-year mortality after LVAD implantation. Nonparametric tests were used to evaluate the device groups., Results: Of 569 patients listed for heart transplant during the study period, 226 had HM3 and 343 had HVAD. The HM3 group had more men (82% vs 74%, P = .02), patients with diabetes (38% vs 29%, P = .02), and the body mass index was higher (28 vs 27 kg/m
2 , P = .04) at listing. Between the HM3 and HVAD groups, the 1-year mortality was 20% vs 17%, respectively (log-rank P = .28; Figure 1), and the posttransplant survival at 1 year was 97% and 94%, respectively (P = .1)., Conclusions: In a relatively well-matched group of patients listed for heart transplant with a centrifugal-flow LVAD, the 6-month and 1-year mortality on the waiting list as well as after transplant were not statistically different. Additional real-world experience or a randomized trial would be needed to determine whether one LVAD is superior., (Copyright © 2022 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Patients with clinically/pathologically diagnosed stage IIIa non-small cell lung cancer (NSCLC) considered for surgery are recommended to undergo neoadjuvant chemotherapy with or without radiation. The timing of an operation after therapy is not standardized; therefore, we investigated the timing of intervention after neoadjuvant therapy and the impact on outcomes in this demographic., Methods: The National Cancer Database was queried between 2010 and 2015 for patients with clinical/pathologic stage IIIa NSCLC. Patients were then divided into short (<77 days), mid (77-114 days), and long delay (>114 days) groups based on interquartile values. These groups were then compared for age, race, gender, insurance type, Charlson-Deyo score, length of stay, readmission rate, and overall survival based on timing of operation., Results: There were 31,357 patients with clinical/pathologic stage IIIa NSCLC, and 5946 patients underwent surgical intervention. Preoperatively 3593 patients underwent chemoradiotherapy, 2185 underwent chemotherapy only, and 168 received radiation alone. The short, mid, and long delay groups were clinically and statistically similar in age, gender, insurance type, comorbidity index, treating facility type, and distance from home. Long delay groups had larger tumor size compared with other groups. Postoperative length of stay, rates of 30-day readmission, and 30- and 90-day mortality were similar across all groups. Cox modeling demonstrated a significant difference in survival when patients underwent earlier operative intervention compared with late operative intervention and when patients received chemoradiation compared with chemotherapy alone. Short, mid, and long delay group 1-year survivals were 82%, 83%, and 80% and 3-year survival 59%, 58%, and 52%, respectively (P = .0003)., Conclusions: The delay in surgical resection of stage IIIa NSCLC is not associated increased early mortality; however, it is associated with worse 3-year postresection survival., (Copyright © 2020 The Society of Thoracic Surgeons.

- Abstract
Background: There is no objective method to estimate post-lung transplant survival solely on the basis of cumulative donor risk factors., Methods: The United Network Organ Sharing thoracic transplant database was queried to identify patients who underwent lung transplantation between 2005 and 2015. A Cox proportional hazard model was generated using a training set to identify donor risk factors significantly associated with posttransplant survival. Significant donor risk factors were assigned a score on the basis of their hazard ratio. Donor risk score was calculated for each patient by adding the individual donor risk factor scores. Donors in the validation set were then categorized into low-risk (score = 0), intermediate-risk (score = 1), and high-risk (score >1) categories on the basis of the cumulative risk score. The Lung Allocation Score was used as a surrogate for recipient risk. Survival for each risk group was calculated using Kaplan-Meier curves., Results: The donor risk groups' respective survival at 1 year was 85%, 81%, and 77%, and at 5 years it was 53%, 50%, and 42% (p < 0.001). The combination of low-risk recipients and low-risk donors had 1- and 5-year survival of 89% and 59%, respectively. The combination of high-risk recipients and high-risk donors had 1- and 5-year survival of 70% and 30%, respectively., Conclusions: The proposed lung donor scoring system is a simple, easy to use method that can aid transplant surgeons in the selection of a potential lung transplant donor. Using the lung donor score in conjunction with the Lung Allocation Score can allow for matching of recipients and donors, to optimize posttransplant outcomes., (Copyright © 2019 The Society of Thoracic Surgeons.

- Abstract
Background: Optimal surgical treatment of infective tricuspid endocarditis is debatable, especially in the setting of inherent social and pathologic concerns. This study compared tricuspid valve repair, replacement, and excision for the treatment of infective endocarditis METHODS: A single-center cardiac surgery database was queried to identify patients aged older than 18 years who underwent tricuspid valve operations for infective endocarditis between 2012 and 2016. Patients were divided into three groups by the type of tricuspid valve operation: valvectomy, repair, or replacement. Patients were evaluated to identify differences between preoperative factors and outcomes, including death, length of stay, and complications., Results: During the study period, 63 patients underwent surgical treatment of infective tricuspid valve endocarditis. Demographic and baseline characteristics were comparable across all groups, except that the valve repair group was older compared with valvectomy and replacement (46 vs 29 and 31 years, respectively; p = 0.007), with more hypertension, elevated creatinine, and a lower incidence of diffuse, bilateral pulmonary emboli. Staphylococcus species were the most common organisms. The incidence of death, bleeding requiring reoperation, major stroke, prolonged ventilator time, intensive care unit stay, and overall hospital length of stay were similar in all groups. Of patients undergoing initial valvectomy, 36% were available for follow-up at 1 year, highlighting the challenges associated with the intravenous drug abuse cohort. Patients who underwent tricuspid valvectomy in the group available for follow-up had significantly lower unplanned readmission rates at 1 year., Conclusions: Tricuspid valve endocarditis patients who undergo tricuspid valve excision, repair, and replacement have similar 30-day operative mortality, as defined by The Society of Thoracic Surgeons. Excision patients have significantly lower unplanned readmission rates at 1 year. Tricuspid valvectomy is an acceptable initial treatment in this high-risk group as part of a surgical strategy to identify patients who are candidates for eventual valve replacement. Further study of long-term outcomes and survival is warranted., (Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

- Abstract
Recent reports have shown an increase in the number of organ donors from drug intoxication. The impact of donor drug use on survival after cardiac transplant remains unclear. The aim of our study was to illustrate changes in donor death mechanisms and assess the impact on posttransplant survival. We queried United Network of Organ Sharing thoracic transplant and deceased donor databases to identify patients undergoing heart transplantation between 2005 and 2015. We evaluated annual trends in donor death mechanisms. Recipients were propensity matched (drug-intoxicated-non-drug-intoxicated = 1:2) and posttransplant survival was compared using Kaplan-Meier curves. In total, 19 384 donor hearts were used for transplant during the period (donor age 31.6 ± 11.8 years, 72% male). Use of drug-intoxicated donors increased from 2% (2005) to 13% (2015) and decreased from blunt injury (40%-30%) and intracranial hemorrhage (29%-25%). After propensity matching, posttransplant survival of drug-intoxicated donor hearts was 90%, 82%, and 76% at 1, 3, and 5 years, which was similar to non-drug-intoxicated. Heart transplants using drug-intoxicated donors have significantly increased; however, they have not adversely affected posttransplant survival. Hearts from drug-intoxicated donors should be carefully evaluated and considered for transplant., (© 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.)

- Abstract
Background: In an effort to expand the donor pool for lung transplants, numerous studies have examined the use of advanced age donors with mixed results, including decreased survival among younger recipients. We evaluated the impact of the use of advanced age donors and single versus double lung transplantation on posttransplant survival., Methods: The United Network for Organ Sharing database was retrospectively queried between January 2005 and June 2014 to identify lung transplant patients aged at least 18 years. Patients were stratified by recipient age 50 years or less, donor age 60 years or more, and single versus double lung transplantation. Overall survival was assessed using the Kaplan-Meier method. Multivariable survival analysis was performed using a Cox proportional hazards model., Results: In all, 14,222 lung transplants were performed during the study period. With univariate analysis, donor lungs aged 60 years or more were associated with slightly worse 5-year survival (44% versus 52%; p < 0.001). Among recipients aged more than 50 years, this trend was not present in the multivariate model (hazard ratio 1.23, p = 0.055). Among recipients aged 50 years or more, receiving older donor lungs showed worse survival with the use of single lung transplant (5-year survival 15% versus 50%, p = 0.01). No significant difference in survival between young and old donors was seen when double lung transplant was performed (p = 0.491). Cox proportional hazards model showed a trend toward interaction between single lung transplantation and older donors (hazard ratio 2.36, p = 0.057)., Conclusions: Reasonable posttransplant outcomes can be achieved with use of advanced age donors in all recipient groups. Double lung transplantation should be performed when older donors (age more than 60) are used in young recipients (age 50 or less)., (Copyright © 2018 The Society of Thoracic Surgeons.

- Abstract
Background: Optimum use of donor organs can increase the reach of the transplantation therapy to more patients on waiting list. The heart transplantation (HTx) has remained stagnant in United States over the past decade at approximately 2,500 HTx annually. With the use of the United Network of Organ Sharing (UNOS) deceased donor database (DCD) we aimed to evaluate donor factors predicting donor heart utilization., Methods: UNOS DCD was queried from 2005 to 2014 to identify total number of donors who had at least one of their organs donated. We then generated a multivariate logistic regression model using various demographic and clinical donor factors to predict donor heart use for HTx. Donor hearts not recovered due to consent or family issues or recovered for nontransplantation reasons were excluded from the analysis., Results: During the study period there were 80,782 donors of which 23,606 (29%) were used for HTx, and 38,877 transplants (48%) were not used after obtaining consent because of poor organ function (37%), donor medical history (13%), and organ refused by all programs (5%). Of all, 22,791 donors with complete data were used for logistic regression (13,389 HTx, 9,402 no-HTx) which showed significant predictors of donor heart use for HTx. From this model we assigned probability of donor heart use and identified 3,070 donors with HTx-eligible unused hearts for reasons of poor organ function (28%), organ refused by all programs (15%), and recipient not located (9%)., Conclusions: An objective system based on donor factors can predict donor heart use for HTx and may help increase availability of hearts for transplantation from existing donor pool., (Copyright © 2017 The Society of Thoracic Surgeons.

- Abstract
Background: Survival following retransplantation with a single lung is worse than after double lung transplant. We sought to characterize survival of patients who underwent lung retransplantation based on the type of their initial transplant, single or double., Methods: The United Network for Organ Sharing database was queried for adult patients who underwent lung retransplantation from 2005 onward. Patients were excluded if they underwent more than one retransplantation. The patient population was divided into 4 groups based on first followed by second transplant type, respectively: single then single, double then single, double then double, and single then double. Descriptive analysis and Kaplan-Meier survival analysis were performed. A p value less than 0.05 was considered significant., Results: A total of 410 patients underwent retransplantation in the study time period. Overall mean survival for all patients who underwent retransplantation was 1,213 days. Kaplan-Meier survival analysis demonstrated no difference in graft survival between the 4 study groups (p = 0.146)., Conclusions: There was no significant difference in graft survival between recipients of retransplant with single or double lungs when stratified by previous transplant type. These results suggest that when retransplantation is performed, single lung retransplantation should be considered, regardless of previous transplant type, in an effort to maximize organ resources., (Copyright © 2017 The Society of Thoracic Surgeons.

- Abstract
Background: Heart transplantation remains the gold standard therapy for end-stage heart failure patients; however, volumes are limited because of donor organ shortage. With the increasing availability of more durable continuous flow left ventricular assist devices (CFLVADs), the matrix of the heart transplantation waiting list and that of donor allocation have seen substantial changes. We aimed to evaluate the impact of the stated reasons for status 1A at time of transplantation on post-transplantation survival in CFVAD patients., Methods: The United Network of Organ Sharing (UNOS) thoracic organ transplantation database was queried between 2006 and 2013 to identify patients aged 18 years or older who underwent heart transplantation as UNOS status 1A. We further assessed the data to identify reasons for status 1A at time of transplantation in CFVAD patients. We also computed post-transplantation survival of patients supported with CFLVAD who were status 1A at the time of transplantation., Results: A total of 15,779 patients underwent heart transplantation during the study time period, of whom 8,429 were Status 1A, and 3,913 had CFLVAD at time of transplantation. Of all status 1A patients, 2,737 had CFLVAD at time of transplantation, of which 52% (1,413) had device complications (thrombosis, infection, malfunction, and other) and 48% (1,314) were on 30-day grace status 1A. Post-transplantation survival (at 3 years) of CFLVAD patients who received a transplant on 30-day grace status 1A was similar to patients who underwent transplantation on status 1B (84% versus 85%, p = 0.5), both of which were significantly better than status 1A patients because of device complications (84% and 85% versus 78%, p = 0.01) (Fig 1)., Conclusions: CFLVAD patients who underwent transplantation as Status 1B or on the 30-day grace Status 1A have similar post-transplantation survival. These data suggest that there needs to be an objective organ allocation system for recipients of heart transplant that prioritize patients with CFVAD complications and patients not eligible for CFVAD for transplantation over 30-day grace period patients., (Copyright © 2016 The Society of Thoracic Surgeons.

- Abstract
The obstruction of blood flow through the superior vena cava (SVC) into the right atrium may present as a severe clinical syndrome. One of the benign causes of SVC obstruction is the long-term use of indwelling catheters and wires, increasing the chances of SVC thrombosis. The treatment of the benign SVC syndrome is focused on achieving long-term durability and patency of the superior venocaval system and normal life expectancy. We report the successful surgical management of a patient with severe symptomatic SVC syndrome and emphasize technical details that might be of value in treating this challenging pathologic condition., (Copyright © 2016 The Society of Thoracic Surgeons.

- Abstract
Background: Quantitative analysis of specific exhaled carbonyl compounds (ECCs) has shown promise for the detection of lung cancer. The purpose of this study is to demonstrate the normalization of ECCs in patients after lung cancer resection., Methods: Patients from a single center gave consent and were enrolled in the study from 2011 onward. Breath analysis was performed on lung cancer patients before and after surgical resection of their tumors. One liter of breath from a single exhalation was collected and evacuated over a silicon microchip. Carbonyls were captured by oximation reaction and analyzed by mass spectrometry. Concentrations of four cancer-specific ECCs were measured and compared by using the Wilcoxon test. A given cancer marker was considered elevated at 1.5 or more standard deviations greater than the mean of the control population., Results: There were 34 cancer patients with paired samples and 187 control subjects. The median values after resection were significantly lower for all four ECCs and were equivalent to the control patient values for three of the four ECCs., Conclusions: The analysis of ECCs demonstrates reduction to the level of control patients after surgical resection for lung cancer. This technology has the potential to be a useful tool to detect disease after lung cancer resection. Continued follow-up will determine whether subsequent elevation of ECCs is indicative of recurrent disease., (Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Donor heart availability has limited the number of heart transplants performed in the United States, while the number of patients waiting for a transplant continues to increase. Optimizing the use of all available donor hearts is important to reduce waiting list deaths and to increase the number of patients who can ultimately undergo a successful heart transplant. Donor cardiopulmonary resuscitation (CPR) time has been proposed to be a selection criterion to consider in donor selection. This study examined whether the duration of donor CPR time affects recipient posttransplantation outcomes and survival., Methods: The United Network of Organ Sharing database was retrospectively queried from January 2005 to December 2013 to identify adult patients who underwent heart transplantation. This population was divided into four groups: donors with no CPR, CPR of less than 20 minutes, CPR of 20 to 30 minutes, and CPR exceeding 30 minutes. Kaplan-Meier analysis was used to compare the recipient posttransplant survival between groups, and posttransplant outcomes were examined. Propensity matching was performed for comparison of posttransplant survival of recipients of donors who did and did not undergo CPR. Multivariable logistic regression analysis was performed to examine individual independent variables for death after transplant., Results: During this period, 17,022 patients underwent heart transplantation. Of those, 16,042 patients received hearts from a donor with no CPR, 639 patients with donor CPR of less than 20 minutes, 154 patients with donor CPR 20 to 30 minutes, and 187 patients with donor CPR exceeding 30 minutes. The posttransplant survival at 1 year for each group was 89% vs 90% vs 88% vs 89% and at 5 years was 75% vs 74% vs 74% vs 72%, respectively, which was not significantly different among the groups. Recipient primary graft failure and rejection rates were similar among the groups. The multivariable regression model showed CPR duration was not an independent risk factor for posttransplant death., Conclusions: Donor CPR does not significantly affect outcomes and survival after transplant. In an effort to optimize donor heart use, donor CPR time alone should not be used to rule out the acceptance of a potential donor heart., (Copyright © 2016 The Society of Thoracic Surgeons.

- Abstract
Background: The shortage of donor hearts has limited cardiac transplantation for end-stage heart failure, leading to the increased use of left ventricular assist devices (LVADs) as bridge-to-transplant (BTT) and marginal donor hearts; however, outcomes have been mixed. This study examines differences in wait list survival of patients with continuous flow LVADs and post-transplantation survival of patients receiving a marginal donor heart., Methods: The United Network of Organ Sharing database was retrospectively queried from January 2005 to June 2013 to identify adult patients listed for heart transplant. Marginal donor criteria included age greater than 55 years, hepatitis C positive, cocaine use, ejection fraction less than 0.45, or donor to recipient body mass index mismatch of greater than 20%. The primary endpoint was wait list survival of patients with LVADs compared with post-transplant survival of marginal donor heart recipients using Kaplan-Meier analysis., Results: A total of 2,561 and 4,737 patients received LVAD support or a marginal donor heart, respectively. The 30-day, 1-year, and 2-year survival was 96%, 89%, and 85%, for patients with LVAD support on the waiting list and 97%, 89%, and 85%, respectively, for recipients of marginal donor hearts (p = 0.213). Recipients of marginal hearts had worse survival than non-marginal heart recipients at 3 years (p = 0.011)., Conclusions: There was no significant difference between waiting list survival of patients with LVAD support as BTT and post-transplant survival of recipients with marginal donor hearts. There could be clinical benefits for using LVAD support as BTT to allow time for better allocation of optimal donor hearts as opposed to transplantation with a marginal donor heart., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Background: Continued donor organ shortage and improved outcomes with current left ventricular assist device (LVAD) technology have increased the number of patients supported with bridge-to-transplantation (BTT) therapy. Using the United Network of Organ Sharing (UNOS) database, we assessed the impact on survival in patients supported with BTT while on the heart transplant waiting list., Methods: The UNOS database was queried from January 2005 to June 2012 to identify patients listed for heart transplantation as UNOS status 1A or 1B. Patients implanted with a pulsatile-flow device or an LVAD other than the HeartMate II (HM II; Thoratec Inc, Pleasanton, CA) were excluded. Patients were divided into LVAD and non-LVAD groups based on status at the time of listing. Patients were propensity matched (LVAD -non-LVAD = 1:2) for age, sex, weight, presence of diabetes, creatinine levels, mean pulmonary artery pressure, and UNOS status. Kaplan-Meier curves were analyzed for survival., Results: A total of 8,688 patients were analyzed, with 1,504 (17%) in the LVAD group. Average age (52.6 ± 11.8 versus 51.3 ± 12.9 years; p = 0.0002) and weight (86.6 ± 18.6 versus 80.8 ± 18.2 kg; p < 0.0001) at time of listing were higher in the LVAD group. There were more men (79% versus 74%; p < 0.0001) and more patients with diabetes (30% versus 27%; p = 0.03) in the LVAD group. Of all patients, 6,943 patients (80%) underwent transplantation, 862 (10%) died, and 883 (10%) remained on the waiting list. After propensity matching, survival to transplantation was significantly better in the LVAD group than in the non-LVAD group at both 1 year (91% versus 77%) and 2 years (85% versus 68%)., Conclusions: Patients supported with an HM II LVAD as BTT therapy were older with increased comorbidities; they demonstrated an improved survival while listed for heart transplantation. The use of LVADs as a BTT strategy can potentially improve patient survival while waiting for transplantation and allow better allocation of donor hearts., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
Background: Despite modern advances in surgical care, triple-valve surgery (TVS) remains a challenge and carries a mortality of 10% to 20%. No validated risk score is available for TVS, and the effect of advanced age is unknown. This study examined our results in the modern era with the aim of identifying perioperative predictors of adverse outcomes., Methods: Between 1997 and 2013, 131 patients (mean age, 67.2±13.4 years) underwent TVS at our institution. Sixty-eight patients (51.9%) were aged 70 years and older. The most common etiology for aortic and mitral disease was degenerative (77.1%), rheumatic (10%), and endocarditis or prosthetic-related, or both, in the rest. Tricuspid valve disease was functional in 96%. New York Heart Association functional class III/IV was present in 69.4%, and 24% had had previous cardiac operations. One or more concomitant cardiac procedures were performed in 77 patients (58.8%), including coronary revascularization in 54. All aortic procedures were replacements, 14 patients required a prosthetic root conduit and 7 thoracic aorta replacement. Mitral replacements were used in 55%, repairs in 45%, and 96.2% of tricuspid procedures were repairs. Univariate and multivariate analyses were used to determine predictors of adverse outcomes., Results: The 30-day and hospital mortality was 10.6% (n=14). Major complications occurred in 70 (53.4%). Univariate analysis identified New York Heart Association functional class III/IV (p=0.04), preoperative renal failure requiring dialysis (p=0.04), urgent operation (p=0.04), intraaortic balloon pump placement (p=0.02), and postoperative low cardiac output (p<0.0001) as predictors for early death. Proximal aortic operations, urgent operation, and New York Heart Association class IV correlated with increased early mortality (p<0.04) in patients aged 70 and older in addition to their decreased overall survival and decreased likelihood of discharge to home. Overall actuarial survival at 1, 5, and 10 years was 84.5%, 75%, and 45%, respectively., Conclusions: TVS remains a surgical challenge in the modern era. Despite a trend of increasing age and surgical risk, the early mortality rate and long-term survival remain respectable. Advanced age is associated with increased perioperative risk, but age per se should not be a contraindication for TVS., (Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Porcine bioprosthesis (bioroots) are an attractive surgical strategy for ascending aorta and arch replacement. This study evaluated the perioperative and late outcomes using this strategy for proximal aortic aneurysmal disease., Methods: Between March 1998 and November 2009, 170 patients (40% women; median age, 70 years) underwent proximal thoracic aortic replacement using the Freestyle (Medtronics Inc, Minneapolis, MN) bioroot, with graft extension in 149 (87.6%). Aneurysmal etiology included degenerative-atherosclerotic (91.2%), acute dissection (5.3%), and chronic dissection (3.5%); 78% had greater than moderate aortic insufficiency. Surgical procedures were bioroot alone or with aortoplasty (12.3%), bioroot with ascending aortic graft (38.2%), bioroot with hemiarch graft (44.1%), and bioroot with total arch (5.3%). Hypothermic circulatory arrest was required in 49%., Results: The 30-day mortality was 4.7% (n=8). The overall complication rate was 58% (n=100), including stroke (6.5%), renal failure (9.2%), respiratory failure (25.9%), and postoperative bleeding (7.6%). Mean hospitalization was 10.5±7.3 days; 38 were discharged to a rehabilitation facility (23.5%). Predictors of 30-day/hospital death were coronary artery disease (p=0.0003), renal insufficiency (p<0.0001), emergent/urgent procedure (p=0.02), and hypothermic circulatory arrest (p=0.002). The 1-year, 5-year, and 10-year survivals were 90%, 80%, and 35% respectively. Freedom from endocarditis and reoperation was 96% at 1 year and 94% and 95% at 5 years, respectively., Conclusions: Proximal thoracic aortic replacement using a porcine bioroot as part of the repair can be achieved with low perioperative mortality and acceptable late survival in a predominantly elderly population., (Copyright © 2011 The Society of Thoracic Surgeons.

- Abstract
Background: Patients listed for heart transplant have a prolonged wait time, with continued deterioration, poor quality of life, and 10% mortality. Although recent bridge to transplant (BTT) studies demonstrated 1-year survival similar to heart transplantation, doubt remains about overall effectiveness as a treatment strategy compared with waiting and implanting a left ventricular device (LVAD) only as a last resort. We evaluated 1-year outcome and effectiveness of LVAD vs heart transplantation., Methods: Patients on the heart transplantation list, either receiving an allograft or LVAD for BTT from January 2009 to December 2009 were evaluated. Of 43 patients treated, 1 received both LVAD and an allograft during same admission was removed from the analysis. All patients but one who received an allograft had prior LVAD. Descriptive and univariate (t test) statistics and Kaplan-Meier survival curve were used for analyses., Results: LVAD for BTT was used in 29 patients (51.4±12.8 years, 6.9% women), and 13 (51.1±11.6 years, 15.38% women) underwent heart transplantation. Initial hospital length of stay was 17.5±14.4 days in BTT group and 14.3±4.6 days in heart transplant group (p=0.44) At 1 year, the total number of days spent in the hospital (operation and related complications), including index hospitalization was 11.6±14.3 days/100 days in BTT and 7.9±9.0 days/100 days in heart transplantation (p=0.38). A total of 41% BTT and 46% heart transplant patients had one readmission within 3 months of the index hospitalization. Infection was the most common cause of readmission in both groups. The 1-year survival was similar for both groups (no hospital death in either group; 3 late deaths in the BTT group)., Conclusions: One-year outcomes for patients eligible for heart transplantation were similar whether they received an allograft or LVAD for BTT. Heart transplant outcome for patients with LVAD were not adversely affected. Improving outcomes for patients treated with LVAD suggest that current decision models for patients eligible for heart transplantation may need to be reevaluated., (Copyright © 2011 The Society of Thoracic Surgeons.
