RESUMO
KCNT1 mutations are associated with childhood epilepsy, developmental delay, and vascular malformations. We report a child with a likely pathogenic KCNT1 mutation (c.1885A>C, p.Lys629Glu) with recurrent pulmonary haemorrhage due to aortopulmonary collaterals successfully managed with coil embolisation followed by right upper lobectomy.

We report a 5-year-old girl with transient complete atrioventricular (AV) block following surgical closure of a symptomatic conoventricular ventricular septal defect (VSD) which recovered on post-operative day 9. She later presented with exertional dizziness and fatigue. While congenital cardiac defect repairs are occasionally complicated by complete heart block, this patient was found to have intra-Hisian Wenckebach which is rare in the pediatric population and can be very difficult to discern from surface electrocardiograms and by Holter monitoring. Mechanisms of post-surgical AV block, including intra-Hisian Wenckebach, are not well characterized in the pediatric population.
RESUMO
BACKGROUND: There is a paucity of information reported regarding the use of milrinone in patients with hypoplastic left heart syndrome prior to the Norwood procedure. At our institution, milrinone is initiated in the pre-operative setting when over-circulation and elevated serum lactate levels develop. We aimed to review the responses associated with the administration of milrinone in the pre-operative hypoplastic left heart syndrome patient. Second, we compared patients who received high- versus low-dose milrinone prior to Norwood procedure. METHODS: Single-centre retrospective study of patients diagnosed with hypoplastic left heart syndrome between January 2000 and December 2019 who underwent Norwood procedure. Patient characteristics and outcomes were compared. RESULTS: During the study period, 375 patients were identified; 79 (21%) received milrinone prior to the Norwood procedure with median lactate 2.55 mmol/l, and SpO2 93%. Patients who received milrinone were older at the time of Norwood procedure (6 vs. 5 days) and were more likely to be intubated and sedated. In a subset analysis stratifying patients to low- versus high-dose milrinone, median lactate decreased from time of initiation (2.39 vs 2.75 to 1.6 vs 1.8 mmol/l) at 12 hours post-initiation, respectively. Repeated measures analysis showed a significant decrease in lactate levels by 4 hours following initiation of milrinone, that persisted over time, with no significant difference in mean arterial pressure. CONCLUSIONS: The use of milrinone in the pre-operative over-circulated hypoplastic left heart syndrome patient is well tolerated, is associated with decreased lactate levels, and was not associated with significant hypotension or worsening of excess pulmonary blood flow.

OBJECTIVES: To describe the characteristics and outcomes associated with concomitant renal and respiratory failure in patients with critical coronavirus disease 2019. DESIGN, SETTING, AND PATIENTS: This is a case series of patients from a U.S. healthcare system in New York City. All adult patients (≥ 18 yr) admitted to the hospital with positive coronavirus disease 2019 testing between March 10, 2020, and March 31, 2020, who required mechanical ventilatory support were included. Patients who remained hospitalized were followed through May 1, 2020. INTERVENTIONS: Renal replacement therapy included at least one session of dialysis, continued venovenous hemofiltration, or peritoneal dialysis. MEASUREMENTS AND MAIN RESULTS: Baseline characteristics, laboratory markers, 30-day in-hospital outcomes, ventilator days, and survival to discharge were included. Multivariate predictors for mortality and need for renal replacement therapy were identified. A total of 330 patients were included in this analysis and were most commonly greater than or equal to 70 years (40%), male (61%), Black or African American (41%), and Hispanic or Latino (38%). Renal replacement therapy was required in 101 patients (29%), most commonly among Blacks or African Americans (50%). Elevated d-dimer, C-reactive protein, and procalcitonin were associated with renal replacement therapy, compared with the nondialysis cohort. Overall, 243 patients (74%) died and 56 (17%) were discharged from the hospital, of which 9 (3%) required renal replacement therapy. Male sex (odds ratio, 2.0; 1.1-3.5; p = 0.020), Black race (odds ratio, 1.8; 1.0-3.1; p = 0.453), and history of hypertension (odds ratio, 2.7; 1.3-5.4; p = 0.005) were predictors for requiring renal replacement therapy. Risk factors for in-hospital mortality included age greater than or equal to 60 years (odds ratio, 6.2; 3.0-13.0; p < 0.0001), male sex (odds ratio, 3.0; 1.4-6.4; p = 0.004), and body mass index greater than or equal to 30 kg/m2 (odds ratio, 2.1; 1.0-4.4; p = 0.039). Concomitant renal failure in critical coronavirus disease 2019 was not a significant predictor of death (odds ratio, 2.3; 0.98-5.5; p = 0.057). CONCLUSIONS: This case series concludes that respiratory failure conveys significant mortality risk in patients with coronavirus disease 2019 and that survival with concomitant renal failure is rare.

BACKGROUND: The impact of frailty status on TAVR outcomes in nonagenarians is unknown. The present study aims to investigate the impact of frailty status on procedural outcomes and overall survival in nonagenarians after TAVR. METHODS: A frailty score (FS) was derived by using preoperative grip strength, gait speed, serum albumin, and daily activities. Patients were divided into two groups: Frail (FS ≥ 3/4) and Non-Frail (FS <3/4). Health status was assessed using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ). Baseline demographic and clinical characteristics were compared in both groups. The effect of frailty status on outcomes was investigated. Cox regression analyses were performed to determine predictors of overall all-cause mortality. Kaplan-Meier survival curves were used to estimate survival. RESULTS: Seventy-five patients >90 years underwent full assessment for frailty status. There was a significant improvement in overall health status of non-frail patients (mean difference: 11.03, P = 0.032). Unadjusted 30-day and 2-year mortality rates were higher in the frail group than the non-frail group. (14% vs. 2% P = 0.059; 31% vs. 9% P = 0.018). Kaplan-Meier estimated all-cause mortality to be significantly higher in the frail group (log-rank test; P = 0.042). Frailty status was independently associated with increased mortality (hazard ratio: 1.84, 95% C.I: 1.06-3.17; P = 0.028) after TAVR. CONCLUSION: Among nonagenarians selected to undergo TAVR for severe aortic stenosis, a considerable number are frail. Nonfrail patients report a significant improvement in overall health status in the short term. Worse frailty is strongly associated with diminished long-term survival. © 2017 Wiley Periodicals, Inc.

BACKGROUND: The study aim was to investigate the relationship between postoperative morbidity after transcatheter aortic valve replacement (TAVR) and short-term patient-reported health status, using the Kansas City Cardiomyopathy Questionnaire (KCCQ). METHODS: The association between 30-day post-procedure changes in patient-reported heath status and post-TAVR outcomes was examined. Patients were stratified into three groups based on observed changes in KCCQ-Overall scores (OS): Group A, increase in KCCQ-OS ≥10 points; Group B, KCCQ-OS scores <10 points; and Group C, decline in KCCQ-OS ≥10 points. Variation components of KCCQ scores were determined using paired t-tests. Postoperative morbidity was investigated. Multivariable logistic regression was used to identify pre-procedural factors associated with an increase or decline in KCCQ-OS at 30 days. RESULTS: A total of 223 patients with complete baseline and postoperative 30-day KCCQ responses was studied. At the 30-day follow up there was a significant change in baseline mean KCCQ-OS for all patients (mean difference 14.1; p <0.0001). Improvement in KCCQ-OS ≥10 was observed in 130 patients (58%), 64 patients (29%) had no change, and 29 patients (13%) had a decline in KCCQ-OS ≥10. The incidence of acute kidney injury (AKI), permanent pacemaker (PPM) placement and new-onset arrhythmia (NOA) was higher in group C than in groups A and B: AKI, 11%, 0%, 0%; p <0.001; PPM, 21%, 4%, 6%; p = 0.004; and NOA, 21%, 5%, 8%, p = 0.026. Independent predictors of decline in KCCQ scores after TAVR were PPM requirement (estimate: 0.76 CI 0.22, 1.29; p = 0.005) and NYHA functional class (III/IV) (estimate: -0.41 CI -0.71, 0.10; p = 0.009). CONCLUSIONS: TAVR patients experienced an improvement in health status after the procedure, but for a smaller proportion their health status worsened. Patients who experience perioperative complications may have a decline in their health status after the procedure in the short term.

BACKGROUND: The purpose of this study is to assess the impact of frailty index comprised of commonly used frailty metrics on outcomes following transcatheter aortic valve replacement (TAVR) outcomes, including mortality, length of stay, and discharge destination. METHODS AND RESULTS: Retrospective data collection was performed for 342 consecutive patients who underwent TAVR at a single center from May 15, 2012, to September 17, 2015. Frailty index score was calculated using 15-ft walk test, Katz activities of daily living, preoperative serum albumin, and dominant handgrip strength. Patients were given a frailty score from 0/4 to 4/4, with higher scores indicating greater levels of frailty. There were 27 patients (8%) in 0/4, 82 patients (24%) in 1/4, 129 patients (38%) in 2/4, 73 patients (21%) in 3/4, and 31 patients (9%) in 4/4 frailty group. Multivariate cox, logistic, and linear regression analyses showed that patients with frailty score of 3/4 or 4/4 had increased all-cause mortality (P = .015 and P < .001) and were more likely to be discharged to an acute care facility (P = .083 and P = .001). 4/4 frail patients had increased post-operative length of stay (P = .014) when compared to less frail patients. Individual components of the frailty score were also independent predictors of all-cause mortality. Median survival in 4/4 frail patients was 7 months. CONCLUSIONS: Frailty index comprised of commonly used frailty metrics and its components are independent predictors of poor post-TAVR outcomes. There is a stepwise increase in mortality and post-TAVR length of stay with increasing frailty with dismal prognosis in extremely frail patients.

OBJECTIVES: To evaluate the association between allocation of donor lungs by geographic sharing type (GST) and lung allocation score (LAS). METHODS: UNOS data included lung transplant recipients between 5/4/05 and 09/30/15 (n = 17 416) grouped by GST of donor lungs: local, regional, or national. Recipients were stratified by LAS <50, 50-75, and >75. Kaplan-Meier analysis was used to assess five-yr survival. RESULTS: The majority of lungs were shared locally (n = 9200; 52.8%) followed by nationally (n = 5356; 30.8%) and regionally (n = 2860; 16.4%). There was a significant difference in the mean LAS at transplant (local: 43.7 ± 15; regional: 49.5 ± 18.8; national 51 ± 19.4; p < 0.001). There was a significant association between GST and LAS (p < 0.001). The majority (n = 7431; 58.2%) of recipients with LAS <50 received local lungs. Recipients with LAS >75 received a majority of their organs from national (n = 881; 45.4%) and regional (n = 414; 21.6%) donors. Although statistically significant (p = 0.024), absolute decline in five-yr survival by GST in the national GST was only 1.1% compared to the local GST. CONCLUSIONS: Nearly half of all lungs in the United States are allocated locally to recipients with an LAS <50. Additional studies should determine if organ sharing over broader geographies would improve waitlist outcomes.

The report is supplemented by a comprehensive review of the literature on Enterobacter cloacae cardiac implantable electronic device infections.
RESUMO
BACKGROUND: Lower institutional volume has been associated with inferior pediatric cardiac surgery outcomes. This study explored the variation in mortality rates among low-, mid-, and high-volume hospitals performing pediatric cardiac surgery in the United States. METHODS: The Kids' Inpatient Database was explored for the years 2016 and 2019. Hospitals performing only off-bypass coarctation and ventricular septal defect repair were omitted. The hospitals were divided into 3 groups by their annual case volume. Multivariable logistic regression models were fit to obtain risk-adjusted in-hospital mortality rates. RESULTS: A total of 25,749 operations performed by 235 hospitals were included in the study. The risk-adjusted mortality rate for the entire sample was 1.9%. There were 140 hospitals in the low-volume group, 64 hospitals in the mid-volume group, and 31 in the high-volume group. All groups had low-mortality (mortality <1.9%) and high-mortality (mortality >1.9%) hospitals. Among low-volume hospitals, 53% were low-mortality (n = 74) and 47% were high-mortality (n = 66) hospitals. Among mid-volume hospitals, 58% were low-mortality (n = 37) and 42% were high-mortality (n = 27) hospitals. Among high-volume hospitals, 68% were low-mortality (n = 21) and 32% were high-mortality (n = 10) hospitals. There was no statistically significant difference in risk-adjusted in-hospital mortality when comparing low-, mid-, and high-volume centers for 7 Society of Thoracic Surgeons benchmark procedures. CONCLUSIONS: This national, real-world, risk-adjusted volume outcome analysis highlights that volume alone may not be the sole arbiter to predict quality of pediatric cardiac surgery outcomes. Using case volume alone as a surrogate for quality may unfairly asperse high-performing, low-volume programs.

BACKGROUND: Societal guidelines support concomitant management of atrial fibrillation (AF) in patients undergoing cardiac surgery. To assess real-world adoption and outcomes, this study evaluated Medicare beneficiaries with AF who underwent isolated coronary artery bypass grafting (CABG) with surgical ablation (SA) or left atrial appendage obliteration (LAAO) or both procedures in combination (SA + LAAO). METHODS: The US Centers for Medicare & Medicaid Services inpatient claims database identified all patients with AF who underwent isolated CABG from 2018 to 2020. Diagnosis-related group and International Classification of Diseases-10th revision procedure codes defined covariates for doubly robust risk adjustment. RESULTS: A total of 19,524 patients with preoperative AF who underwent isolated CABG were stratified by SA + LAAO (3475 patients; 17.8%), LAAO only (4541 patients; 23.3%), or no AF treatment (11,508 patients; 58.9%). After doubly robust risk adjustment, longitudinal analysis highlighted that concomitant AF treatment with SA + LAAO (hazard ratio [HR], 0.74; P = .049) or LAAO alone (HR, 0.75; P = . 031) was associated with a significant reduction in readmission for stroke at 3 years compared with no AF treatment. Furthermore, SA + LAAO (HR, 0.86; P = .016) but not LAAO alone (HR, 0.97; P = .573) was associated with improved survival compared with no AF treatment. Finally, SA + LAAO was associated with a superior composite outcome of freedom from stroke or death at 3 years compared with LAAO alone (HR, 0.86;, P = .033) or no AF treatment (HR, 0.81; P = .001). CONCLUSIONS: In Medicare beneficiaries with AF who underwent isolated CABG, concomitant AF treatment was associated with reduced 3-year readmission for stroke. SA + LAAO was associated with superior reduction in stroke or death at 3 years compared with LAAO alone or no AF treatment.

OBJECTIVE: Recent approval of transcatheter aortic valve replacement (TAVR) in patients at low surgical risk has resulted in a rapid real-world expansion of TAVR in patients not otherwise examined in recent low-risk trials. We sought to evaluate the outcomes of surgical aortic valve replacement (SAVR) versus TAVR in low-risk Medicare beneficiaries. METHODS: Using the US Centers for Medicare and Medicaid Services claims database, we evaluated all beneficiaries undergoing isolated SAVR (n = 33,210) or TAVR (n = 77,885) (2018-2020). International Classification of Diseases 10th revision codes were used to define variables and frailty was defined by the validated Kim index. Doubly robust risk adjustment was performed with inverse probability weighting and multilevel regression models, as well as competing-risk time to event analysis. A low-risk cohort was identified to simulate recent low-risk trials. RESULTS: A total of 15,749 low-risk patients (8144 SAVR and 7605 TAVR) were identified. Comparison was performed with doubly robust risk adjustment accounting for all factors. TAVR was associated with lower perioperative stroke (odds ratio, 0.62; P < .001) and hospital mortality (odds ratio, 0.16; P < .001) compared with SAVR. However, risk-adjusted longitudinal analysis demonstrated TAVR was associated with higher late risk of stroke (hazard ratio, 1.65; P < .001), readmission for valve reintervention (hazard ratio, 1.88; P < .001), and all-cause mortality (hazard ratio, 1.54; P < .001) compared with SAVR. CONCLUSIONS: Among low-risk Medicare beneficiaries younger than age 75 years undergoing isolated AVR, SAVR was associated with higher index morbidity and mortality but improved 3-year risk-adjusted stroke, valve reintervention, and survival compared with TAVR.
RESUMO
BACKGROUND: Societal guidelines support atrial fibrillation (AF) treatment during surgical aortic valve replacement (SAVR). Recently, many patients with AF at low to intermediate risk are managed by transcatheter aortic valve replacement (TAVR). Therefore, we evaluated longitudinal outcomes in these populations. METHODS: The United States Centers for Medicare and Medicaid Services inpatient claims database was evaluated for all beneficiaries with AF undergoing TAVR or SAVR with/without AF treatment (2018-2020). Treatment of AF included concomitant left atrial appendage obliteration, with/without surgical ablation, or endovascular appendage occlusion and/or catheter ablation at any time. Diagnosis-related group and International Classification of Diseases, 10th Revision, codes defined procedures with doubly robust risk adjustment across each group. RESULTS: A total of 24,902 patients were evaluated (17,453 TAVR; 7,449 SAVR). Of patients undergoing SAVR, 3176 (42.6%) underwent AF treatment (SAVR+AF). Only 656 TAVR patients (4.5%) received AF treatment. Comparing well-balanced SAVR+AF vs SAVR vs TAVR, there were no differences in the in-hospital incidence of renal failure, bleeding, or stroke, but increased pacemaker requirement (odds ratio [OR], 3.45; P < .0001) and vascular injury (OR, 9.09; P < .0001) were noted in TAVR and higher hospital mortality (OR, 4.02; P < .0001) in SAVR+AF. SAVR+AF was associated with lower readmission for stroke compared with SAVR alone (hazard ratio [HR], 0.87; P = .029) and TAVR (HR, 0.68; P < .0001) and with improved survival vs TAVR (HR, 0.79; P = .019). CONCLUSIONS: In Medicare beneficiaries with AF requiring aortic valve replacement, SAVR+AF was associated with improved longitudinal survival and freedom from stroke compared with TAVR. SAVR+AF treatment should be considered first-line therapy for patients with AF requiring aortic valve replacement.

BACKGROUND: Despite prospective randomized evidence supporting concomitant treatment of atrial fibrillation (AF) during mitral valve (MV) surgery, variation in surgical management of AF remains. We assessed longitudinal outcomes after surgical treatment of persistent or paroxysmal AF during MV surgery in Medicare beneficiaries. METHODS: All Medicare beneficiaries with a diagnosis of AF undergoing MV surgery (2018-2020) were evaluated. Patients were stratified by no AF treatment, left atrial appendage obliteration (LAAO) alone, or surgical ablation and LAAO (SA+LAAO). Doubly robust risk adjustment and subgroup analysis by persistent or paroxysmal AF were performed. RESULTS: A total of 7517 patients with preoperative AF underwent MV surgery (32.1% no AF treatment, 23.1% LAAO alone, 44.7% SA+LAAO). After doubly robust risk adjustment, AF treatment with SA+LAAO or LAAO alone were associated with lower 3-year readmission for stroke or bleeding. However, SA+LAAO was associated with reduced 3-year mortality and readmission for AF or heart failure compared with no AF treatment or LAAO alone. Compared with no AF treatment or LAAO alone, SA+LAAO was associated with lower composite end point of stroke (hazard ratio, 0.75) or death (hazard ratio, 0.83) at 3 years. Subgroup analysis identified similar longitudinal benefits of SA+LAAO in patients with persistent or paroxysmal AF. CONCLUSIONS: In Medicare beneficiaries with AF undergoing MV surgery, SA+LAAO was associated with improved longitudinal outcomes compared with LAAO alone or no AF treatment in patients with paroxysmal or persistent AF. These contemporary real-world data further clarify the benefit of SA+LAAO during MV surgery across all types of AF.
RESUMO
BACKGROUND: Infants with single-ventricle physiology have increased morbidity, mortality, and ventricular dysfunction in the pre-superior cavopulmonary anastomosis (pre-SCPA) period. Echocardiography-derived longitudinal strain (LS) is emerging as a reliable marker of single-ventricle performance. We aim to assess evolution of LS during the pre-SCPA period across univentricular morphologies and explore associations of LS with modifiable and nonmodifiable factors. METHODS: Ninety-four term infants (36 females) with univentricular physiology who were discharged home prior to stage 2 palliation were serially analyzed for LS (single apical view) and other echo measures at initial hospital discharge and the last pre-SCPA encounter. Ventricular myocardium was tracked for strain along the septum and respective lateral wall for single right ventricular (RV) and left ventricular (LV) groups, and along both right and left lateral walls in functionally univentricular hearts with biventricular (BiV) morphology. Clinical data were obtained from the medical record. RESULTS: Longitudinal strain improved in the total cohort during the pre-SCPA period (16.48% ± 3.31% to 17.57% ± 3.81%, P = .003). Longitudinal strain improved between encounters in the single LV (P = .04) and BiV groups (P = .02). However, LS failed to improve in the RV group (P = .7) with lower LS at both visits compared with the other groups. The RV group, mostly composed of hypoplastic left heart syndrome patients-87% of cases-had a higher incidence of arrhythmias (57%) and unplanned reinterventions (60%), most of which were arch reinterventions. A subanalysis based on arch reintervention showed that LS improves between encounters in the single LV group needing arch reintervention (P = .05) compared with the single RV group needing arch reintervention (P = .89). Lower LS was independently associated with unplanned reinterventions at both encounters (P = .008 and .02). CONCLUSIONS: Single-ventricle LS evolves differently across ventricular morphologies during the pre-SCPA period and is related to the need for unplanned cardiac reinterventions. Lower LS is noted in the single RV group, who mostly have hypoplastic left heart syndrome.

BACKGROUND: ABO-incompatible heart transplant is a method to increase the infant donor pool. However data on long-term survival and rejection after ABO-incompatible heart transplant in recent era are limited. METHODS: The United Network for Organ Sharing database was queried for infant heart transplants performed from January 2008 to March 2020. Patient demographics and known risk factors for posttransplant mortality were collected. Statistical analysis using Bayesian additive regression trees was performed to evaluate the association of ABO incompatibility and overall survival, graft survival, acute rejection episodes, and length of stay. RESULTS: Of 1368 included infants (age < 1 year), 280 (20.47%) were ABO incompatible. ABO incompatibility was not associated with increased all-cause mortality, acute rejection episodes, or length of stay, whereas extracorporeal membrane oxygenation and intubation status of the recipient at the time of transplantation were associated with increased all-cause mortality and graft failure. Idiopathic cardiomyopathy was associated with a decreased likelihood of posttransplant all-cause mortality. One-, 5-, and 10-year survival rates among compatible vs incompatible transplants were estimated to be 90% vs 88%, 82% vs 79%, and 77% vs 73%, respectively. CONCLUSIONS: ABO-incompatible infant heart transplant does not affect posttransplant survival, incidence of rejection, or postoperative length of stay. Therefore it remains a viable and important strategy to increase the infant donor pool.

Acute type A aortic dissection requires timely diagnosis and intervention. Previous studies have examined risk factors associated with delayed diagnosis; however, the effect of socioeconomic status (SES) has not been previously studied. Our study examined the impact of various SES measures on time to diagnosis. We examined time to diagnosis in consecutive cases of acute type A aortic dissection at a single institution. SES variables included race/ethnicity, Medicaid eligibility, and residence in a zip code with an increased Distressed Communities Index-an aggregate measure of community SES. Delayed diagnosis was defined as time to diagnosis in the upper quartile of the study population (>6.6 hours). A model predicting risk factors for delayed diagnosis was created using multivariable logistic regression. Our study included 124 patients with a median time to diagnosis of 3.36 hours (interquartile range [IQR] 1.83 to 6.63). A total of 92 patients were in the nondelayed cohort (median diagnosis time of 2.59 hours, IQR 1.49 to 4.18) and 32 patients were in the delayed cohort (median diagnosis time of 15.57 hours, IQR 9.34 to 28.75). In multivariable logistic regression, residence in a high-Distressed Communities Index zip code was associated with diagnostic delay (adjusted odds ratio [aOR] 5.108, p = 0.008). Patient age (aOR 0.944, p = 0.011), chest pain at presentation (aOR 0.099, p = 0.004), back pain at presentation (aOR 0.247, p = 0.012), evidence of malperfusion syndrome (aOR 0.040, p <0.001), history of hyperlipidemia (aOR 3.507, p = 0.026), and history of congestive heart failure (aOR 0.061, p = 0.036) were also significantly associated. In conclusion, our findings suggest community-level SES affects time to diagnosis in acute type A aortic dissection.

BACKGROUND: Glass tables can break and cause traumatic injury. This public health issue is avoidable by adequate regulatory measures. We describe the burden and characteristics of these injuries using the National Electronic Injury Surveillance System (NEISS) database and data from a level 1 trauma center. METHODS: NEISS data was extracted from 2009 to 2015. Injuries were classified by type, severity, and involvement of faulty glass using predetermined criteria. A retrospective chart review of a level 1 trauma center data was performed. Epidemiologic and outcomes data are reported. RESULTS: 3241 cases were reviewed from NEISS. 56% of injuries were attributable to faulty tables. 15% were severe. A bimodal age distribution of age under 7 and early 20s was observed. Commonly injured areas were the upper extremity and forehead. 24 trauma center cases were reviewed. 21% presented with hemodynamic instability, 34% had major organ, body cavity or joint space injuries, and 58% required surgical intervention. 30-day mortality rate was 8%. More than 54% required inpatient care. CONCLUSION: Glass table injuries are common, estimated at over 2.5 million per year. Regulation of glass quality may prevent injury. SUMMARY: Glass table injuries are more common than may be recognized and represent a public health problem that can be mitigated through proper regulatory measures.

BACKGROUND: This study describes the impact of continuous-flow left-ventricular-assist device (CF-LVAD)-related complications on postoperative outcomes. METHODS: The United Network for Organ Sharing (UNOS) heart transplant follow-up data from 2005 to 2015 were obtained. CF-LVAD patients who were bridged to transplant were studied. Device-related complications (DRCs) at patient's last follow-up before transplantation were reported in 5 categories: device thrombosis (B1), infection (B2), device malfunction (B3), life-threatening arrhythmias (B4), and others (B5). Multivariable Cox regression models were used to evaluate the association of each category of complications and number of complications with postoperative graft survival. RESULTS: Of 3,877 patients analyzed, incidence of DRCs was as following: 374 (9.65%) for thrombosis (B1), 869 (22.41%) for device-related infection (B2), 400 (10.32%) for device malfunction (B3), 135 (3.48%) for life-threatening arrhythmias (B4), and 510 (13.15%) for others (B5). A total of 2,018 (52.05%) patients did not have any DRC at last follow-up; 1,482 (38.23%) patients had 1 DRC and 377 (9.72%) patients had 2 or more DRCs. Mean time from last preoperative follow-up to transplant in patients with 0, 1, and 2 or more DRCs was 93, 18, and 11 days, respectively. Multivariate analysis showed that none of the complications (from B1 to B5) were independent risk factors for poor graft survival after cardiac transplantation. Independent predictors of postoperative graft failure were increasing donor age, inpatient status, increasing body mass index, poor functional status, ventilator dependence, and extracorporeal membrane oxygenation at the time of transplant. CONCLUSIONS: DRCs are common among advanced heart failure patients bridged to transplant with CF-LVADs. Contrary to popular belief, DRCs are not associated with poor postoperative graft survival.
