Socioeconomic status as a predictor of post-operative mortality and outcomes in carotid artery stenting vs. carotid endarterectomy. Front Cardiovasc Med 2024; 11:1286100. [PMID: 38385132 PMCID: PMC10879273 DOI: 10.3389/fcvm.2024.1286100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 01/08/2024] [Indexed: 02/23/2024] Open
Abstract
Background The association between low socioeconomic status (SES) and worse surgical outcomes has become an emerging area of interest. Literature has demonstrated that carotid artery stenting (CAS) poses greater risk of postoperative complications, particularly stroke, than carotid endarterectomy (CEA). This study aims to compare the impact of low SES on patients undergoing CAS vs. CEA. Methods The National Inpatient Sample (NIS) was queried for patients undergoing CAS and CEA from 2010 to 2015. Patients were stratified by highest and lowest median income quartiles by zip code and compared through demographics, hospital characteristics, and comorbidities defined by the Charlson Comorbidity Index (CCI). Primary outcome was in-hospital mortality. Secondary outcomes included acute kidney injury (AKI), post-operative stroke, sepsis, and bleeding requiring reoperation.Multivariable logistic regression was used to determine the effect of SES on outcomes. Results Five thousand four hundred twenty-five patients underwent CAS (Low SES: 3,516 (64.8%); High SES: 1,909 (35.2%) and 38,399 patients underwent CEA (Low SES: 22,852 (59.5%); High SES: 15,547 (40.5%). Low SES was a significant independent predictor of mortality [OR = 2.07 (1.25-3.53); p = 0.005] for CEA patients, but not for CAS patients [OR = 1.21 (CI 0.51-2.30); p = 0.68]. Stroke was strongly associated with low SES, CEA patients (Low SES = 1.5% vs. High SES = 1.2%; p = 0.03), while bleeding was with high SES, CAS patients (Low SES = 5.3% vs. High SES = 7.1%; p = 0.01). CCI was a strong predictor of mortality for both procedures [CAS: OR1.45 (1.17-1.80); p < 0.001. CEA: OR1.60 (1.45-1.77); p < 0.001]. Advanced age was a predictor of mortality post-CEA [OR = 1.03 (1.01-1.06); p = 0.01]. While not statistically significant, advanced age and increased mortality trended towards a positive association in CAS [OR = 1.05 (1.00-1.10); p = 0.05]. Conclusions Low SES is a significant independent predictor of post-operative mortality in patients who underwent CEA, but not CAS. CEA is also associated with higher incidence of stroke in low SES patients. Findings demonstrate the impact of SES on outcomes for patients undergoing carotid revascularization procedures. Prospective studies are warranted to further evaluate this disparity.

Ambulatory Electrocardiography Monitoring for Early Discharge After Minimally Invasive Valve Surgery. J Surg Res 2023; 292:182-189. [PMID: 37633247 DOI: 10.1016/j.jss.2023.07.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 07/11/2023] [Accepted: 07/13/2023] [Indexed: 08/28/2023]
Abstract
INTRODUCTION We sought to compare outcomes after early discharge in patients with and without predischarge diagnosis of arrhythmia following minimally invasive valve surgery (MIVS). MATERIALS AND METHODS We retrospectively reviewed ambulatory electrocardiography (AECG) datasheets and medical records of patients discharged with 14-d AECG monitoring from our facility between October 2019 and March 2022 ≤ 3 d after MIVS. Baseline and clinical characteristics, arrhythmias during AECG monitoring, and 30-d adverse outcomes were reported for the population and stratified by presence or absence of predischarge arrhythmia. RESULTS Of 41 patients discharged ≤3 d postoperatively of MIVS, 17 (41.5%) experienced predischarge arrhythmias and 24 (58.5%) did not. The population was predominantly male and White with a median age of 62 y [57, 70]. Baseline and clinical characteristics did not differ between subgroups. Most patients (92.7% [n = 38]) experienced one or more tachyarrhythmias during the AECG monitoring period. There were similar proportions of patients experiencing atrial fibrillation in both groups, but patients with predischarge arrhythmias had higher burden of atrial fibrillation on AECG monitoring (27.60% [6.57%, 100%] versus 1.65% [0.76%, 4.32%]; P = 0.004). The predischarge arrhythmia subgroup had higher proportions of patients experiencing nonsustained ventricular tachycardia but lower proportions experiencing supraventricular tachycardia. There were no mortalities within 30 d of surgery. Six (14.6%) patients were readmitted within 30 d with equal proportions of readmissions between subgroups (P = 0.662). CONCLUSIONS Early discharge timelines and noninvasive monitoring techniques can allow patients to return to their normal activities quicker in the comfort of their own home with no increased risk of morbidity or mortality.

Abstract
Objective To investigate the effect of minimally invasive cardiac surgery (MICS) on resource utilization, cost, and postoperative outcomes in patients undergoing left-heart valve operations. Methods Data were retrospectively reviewed for patients undergoing single-valve surgery (eg, aortic valve replacement, mitral valve replacement, or mitral valve repair) at a single center from 2018 to 2021, stratified by surgical approach: MICS vs full sternotomy (FS). Baseline characteristics and postoperative outcomes were compared. Primary outcome was high resource utilization, defined as direct procedure cost higher than the third quartile or either postoperative LOS ≥7 days or 30-day readmission. Secondary outcomes were direct cost, length of stay, 30-day readmission, in-hospital and 30-day mortality, and major morbidity. Multiple regression analysis was conducted, controlling for baseline characteristics, operative approach, valve operation, and lead surgeon to assess high resource utilization. Results MICS was correlated with a significantly lower rate of high resource utilization (MICS, 31.25% [n = 115] vs FS 61.29% [n = 76]; P < .001). Median postoperative length of stay (MICS, 4 days [range, 3-6 days] vs FS, 6 days [range, 4 to 9 days]; P < .001) and direct cost (MICS, $22,900 [$19,500-$28,600] vs FS, $31,900 [$25,900-$50,000]; P < .001) were lower in the MICS group. FS patients were more likely to experience postoperative atrial fibrillation (P = .040) and renal failure (P = .027). Other outcomes did not differ between groups. Controlling for stratified Society of Thoracic Surgeons predicted risk of mortality, cardiac valve operation, and lead surgeon, FS demonstrated increased likelihood of high resource utilization (P < .001). Conclusions MICS for left-heart valve pathology demonstrated improved postoperative outcomes and resource utilization.

Abstract
INTRODUCTION Time is the greatest challenge in stroke management. This study aimed to examine factors contributing to prehospital delay and decision delay among stroke patients. MATERIALS AND METHODS A cross-sectional study involving acute stroke patients admitted to Seri Manjung Hospital was conducted between August 2019 and October 2020 via faceto- face interview. Prehospital delay was defined as more than 120 minutes taken from recognition of stroke symptoms till arrival in hospital, while decision delay was defined as more than 60 minutes taken from recognition of stroke symptoms till decision was made to seek treatment. RESULTS The median prehospital delay of 102 enrolled patients was 364 minutes (IQR 151.5, 1134.3) while the median for decision delay was 120 minutes (IQR 30.0, 675.0). No history of stroke (adj. OR 4.15; 95% CI 1.21, 14.25; p=0.024) and unaware of thrombolysis service (adj. OR 17.12; 95% CI 1.28, 229.17; p=0.032) were associated with higher odds of prehospital delay, while Indian ethnicity (adj. OR 0.09; 95% CI 0.02, 0.52; p=0.007) was associated with lower odds of prehospital delay as compared to Malay ethnicity. On the other hand, higher National Institutes of Health Stroke Scale (NIHSS) score (adj. OR 0.86; 95% CI 0.78, 0.95; p=0.002) was associated with lower odds of decision delay. CONCLUSION Public awareness is crucial to shorten prehosital delay and decision delay for better patients' outcomes in stroke. Various public health campaigns are needed to improve the awareness for stroke.

Does arterial cannulation site for aortic dissection repair impact surgical outcomes? J Thorac Dis 2023; 15:1057-1062. [PMID: 37065559 PMCID: PMC10089872 DOI: 10.21037/jtd-22-576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 09/02/2022] [Indexed: 03/06/2023]
Abstract
Background Establishing cardiopulmonary bypass remains critical to the successful repair of an acute type A aortic dissection. A recent trend away from femoral arterial cannulation has occurred in part due to concerns of stroke risk from retrograde perfusion to the brain. The purpose of this study was to determine if arterial cannulation site for aortic dissection repair impacts surgical outcomes. Methods A retrospective chart review was performed at Rutgers Robert Wood Johnson Medical School from January 1st, 2011 to March 8th, 2021. Of the 135 patients included, 98 (73%) underwent femoral arterial cannulation, 21 (16%) axillary artery cannulation, and 16 (12%) direct aorta cannulation. The study variables included demographic data, cannulation site, and complications. Results The mean age was 63.6±14 years, with no difference between the femoral, axillary, and direct cannulation groups. Eighty-four patients (62%) were male, with similar percentages amongst each group. The rates of bleeding, stroke, and mortality specifically due to the arterial cannulation did not significantly differ based on cannulation site. None of the patients had strokes that were attributable to cannulation type. No patients died as a direct complication of arterial access. The overall in-hospital mortality was 22%, similar between groups. Conclusions This study found no statistically significant different in rates of stroke or other complications based on cannulation site. Femoral arterial cannulation thus remains a safe and efficient choice for arterial cannulation in the repair of acute type A aortic dissection.

Is cardiopulmonary bypass standby still required for laser lead extractions? J Cardiothorac Surg 2022; 17:235. [PMID: 36109812 PMCID: PMC9476252 DOI: 10.1186/s13019-022-01987-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Accepted: 08/24/2022] [Indexed: 11/30/2022] Open
Abstract
Objective Over the last two decades there has been an increase in the number of cardiac implantable electronic devices and consequently, there has also been an increased need for lead extractions. Fibrotic attachments develop between the lead and the venous and cardiac structures that may require the use of a laser to mobilize the lead. Cardiothoracic surgeons (CTS) have traditionally provided backup for surgical emergencies for these extractions. This study evaluates the surgical outcomes of patients undergoing transvenous laser lead extractions (TLE) and determines if CTS are still needed for backup. Methods A retrospective review of consecutive patients undergoing laser lead extractions at a single academic center. Lead extractions using only laser sheaths were analyzed. The clinical characteristics, complications, and mortality of the patients were evaluated. Results One hundred and twenty-one patients underwent TLEs from January 1st, 2014 to December 31st, 2018. The majority were male (N = 80, 66.1%), and the average age was 66.48 ± 14 years. The indication for removal was either laser lead malfunction or infection. A total of 30 patients (24.8%) had complications postoperatively including wound hematomas, superficial infections, and arrhythmias. The average length of stay was 9 ± 12 for all the patients in the study. 2 patients (1.6%) had injuries that required emergency surgical repair with injuries to the posterior superior vena cava and right ventricle. Both patients survived the initial injury with one patient was discharged home on day 4 and the other succumbing to his injuries on postoperative day 20. Conclusion Although the incidence of surgical emergencies is rare the morbidity and mortality for TLE require that surgical backup be available.

Abstract
Objective Bioprosthetic surgical aortic valve replacement remains an important treatment option in the era of transcatheter interventions. Real-world outcomes are not well characterized because of limited prospective follow-up studies. We present the 10-year clinical outcomes of Medicare beneficiaries undergoing surgical aortic valve replacement with a contemporary supra-annular porcine valve. Methods This is a single-arm observational study using Medicare fee-for-service claims data. De-identified patients undergoing surgical aortic valve replacement with the Epic Supra valve (Abbott) in the United States between January 1, 2008, and December 31, 2019, were selected by International Classification of Diseases 9th and 10th Revision procedure codes and then linked to a manufacturer device tracking database. All-cause mortality, heart failure rehospitalization, and aortic valve reintervention (surgical or transcatheter valve-in-valve) were evaluated at 10 years using the Kaplan-Meier method. Results Among 272,591 Medicare beneficiaries undergoing surgical aortic valve replacement during the study period, 11,685 received the Epic Supra valve, of whom 51.6% (6029) had underlying heart failure. Mean age was 76 ± 7 years. Survival at 10 years in patients without preoperative heart failure was 43.5% (95% confidence interval, 41.8-45.2) compared with 24.1% (95% confidence interval, 22.6-25.5) for patients with heart failure (P < .001). The 10-year freedom from heart failure rehospitalization was 64.0% (95% confidence interval, 62.6-65.3). Freedom from aortic valve reintervention was 94.6% (95% confidence interval, 93.8-95.3) at 10 years. Conclusions This real-world nationwide study of US Medicare beneficiaries receiving the Epic Supra valve demonstrates more than 94% freedom from all-cause valve reintervention and 64% freedom from heart failure rehospitalization at 10 years postimplant. Long-term survival and heart failure rehospitalization in this population with aortic valve disease undergoing surgical aortic valve replacement were found to be impacted by underlying heart failure.

Abstract
BACKGROUND We investigated patient outcomes in relation to their postoperative length of stay after minimally invasive valve surgery. METHODS All adults who survived elective, uncomplicated minimally invasive aortic or mitral valve surgery at a single center between 2012 and 2019 were classified by postoperative length of stay: early discharge (≤3 days) or late discharge (>3 days). The trend in early discharge was investigated over the study period, predictors of early discharge were identified using multivariate logistic regression modeling, and 1:1 propensity score matching was used to determine which patients in the late-discharge cohort had similar health to patients discharged early. Adjusted outcomes of 30-day mortality, readmission, and direct costs were analyzed. RESULTS Among 1262 consecutive patients undergoing minimally invasive valve surgery, 618 were elective and uncomplicated, 25% (n = 162) of whom were discharged early. The proportion of early-discharge patients increased over time (P for trend < .05). A history of congestive heart failure, stroke, or smoking and higher Society of Thoracic Surgeons predictive risk of mortality score negatively predicted early discharge (P < .05). Propensity score matching identified 101 (22%) late-discharge patients comparable with early-discharge patients. Adjusted 30-day mortality and readmission rates were comparable between cohorts. The median direct costs per patient ($20,046 vs $22,124, P < .05) were significantly lower in the early-discharge cohort. CONCLUSIONS In well-selected patients early discharge after minimally invasive valve surgery was associated with lower costs but comparable postoperative outcomes. About one-fifth of patients who remain in the hospital beyond postoperative day 3 may be candidates for earlier discharge.

Abstract
BACKGROUND To derive and validate a risk score that accurately predicts 1-year mortality after heart transplantation (HT) in patients bridged to transplant (BTT) with a left ventricular assist device (LVAD). METHODS The UNOS database was queried to identify patients BTT with an LVAD between 2008 and 2018. Patients with ⩾1-year follow up were randomly divided into derivation (70%) and validation (30%) cohorts. The primary endpoint was 1-year mortality. A simple additive risk score was developed based on the odds of 1-year mortality after HT. Risk groups were created, and survival was estimated and compared. RESULTS A total of 7759 patients were randomly assigned to derivation (n = 5431) and validation (n = 2328) cohorts. One-year post-transplant mortality was 9.8% (n = 760). A 33-point scoring was created from six recipient variables and two donor variables. Risk groups were classified as low (0-5), intermediate (6-10), and high (>10). In the validation cohort, the predicted 1-year mortality was significantly higher in the high-risk group than the intermediate and low-risk groups, 14.7% versus 9% versus 6.1% respectively (log-rank test: p < 0.0001). CONCLUSION The BTT-LVAD Score can serve as a clinical decision tool to guide therapeutic decisions in advanced heart failure patients.

Abstract
Heparin purge solution is recommended to be used in Impella devices to prevent biomaterial buildup and subsequent device dysfunction. The use of sodium bicarbonate purge solution in an Impella device is described in two patients with heparin-induced thrombocytopenia (HIT). The first case details a patient with severe mitral regurgitation and cardiogenic shock who had an Impella CP placed who developed HIT. Heparin purge solution was replaced by sodium bicarbonate purge solution in addition to systemic direct thrombin inhibitor (DTI) initiation. There was no significant change in Impella purge pressure or flow over the 13 days of Impella use. The second case describes a patient who developed an acute myocardial infarction and subsequent cardiogenic shock for which an Impella CP was placed who also developed HIT. Heparin purge solution was replaced by sodium bicarbonate purge solution. There was no significant change in purge pressure, flow, or motor current spikes over 11 days of use. In conclusion, we describe the successful use of a novel sodium bicarbonate purge solution utilized in patients with HIT for Impella management alone and in combination with systemic direct thrombin inhibitor therapy. This resulted in no protein deposition in the device gaps or device dysfunction.

[PMID: 34949396 DOI: 10.1016/j.jcin.2021.08.039] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 07/27/2021] [Accepted: 08/17/2021] [Indexed: 01/06/2023]
Abstract
OBJECTIVES The aim of this study was to determine the impact of delayed high-degree atrioventricular block (HAVB) or complete heart block (CHB) after transcatheter aortic valve replacement (TAVR) using a minimalist approach followed by ambulatory electrocardiographic (AECG) monitoring. BACKGROUND Little is known regarding the clinical impact of HAVB or CHB in the early period after discharge following TAVR. METHODS A prospective, multicenter study was conducted, including 459 consecutive TAVR patients without permanent pacemaker who underwent continuous AECG monitoring for 14 days (median length of hospital stay 2 days; IQR: 1-3 days), using 2 devices (CardioSTAT and Zio AT). The primary endpoint was the occurrence of HAVB or CHB. Patients were divided into 3 groups: 1) no right bundle branch block (RBBB) and no electrocardiographic (ECG) changes; 2) baseline RBBB with no further changes; and 3) new-onset ECG conduction disturbances. RESULTS Delayed HAVB or CHB episodes occurred in 21 patients (4.6%) (median 5 days postprocedure; IQR: 4-6 days), leading to PPM in 17 (81.0%). HAVB or CHB events were rare in group 1 (7 of 315 [2.2%]), and the incidence increased in group 2 (5 of 38 [13.2%]; P < 0.001 vs group 1) and group 3 (9 of 106 [8.5%]; P = 0.007 vs group 1; P = 0.523 vs group 2). No episodes of sudden or all-cause death occurred at 30-day follow-up. CONCLUSIONS Systematic 2-week AECG monitoring following minimalist TAVR detected HAVB and CHB episodes in about 5% of cases, with no mortality at 1 month. Whereas HAVB or CHB was rare in patients without ECG changes post-TAVR, baseline RBBB and new-onset conduction disturbances determined an increased risk. These results would support tailored management using AECG monitoring and the possibility of longer hospitalization periods in patients at higher risk for delayed HAVB or CHB.

Utilizing ambulatory electrocardiogram monitoring to reduce conduction related death after transcatheter aortic valve replacement. Catheter Cardiovasc Interv 2021; 99:1243-1250. [PMID: 34851550 DOI: 10.1002/ccd.30027] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/18/2021] [Accepted: 11/17/2021] [Indexed: 11/05/2022]
Abstract
OBJECTIVE The purpose of this study is to assess the utility of ambulatory cardiac monitoring (ACM) in detecting delayed advanced conduction abnormalities (DACA) and associated 30-day mortality. BACKGROUND DACA are well-known complications of TAVR and may be associated with post-discharge mortality within 30-days. METHODS Between October 2019 and October 2020, TAVR patients who were discharged home without a permanent pacemaker (PPM) were monitored with an ACM device for 14-days. The incidence of DACA at follow up, mortality and readmission within 30-days were investigated. The risk of DACA was assessed in three patient categories based on a composite of their 12-lead electrocardiogram (ECG) data. Group I: Normal pre-TAVR, periprocedural, and discharge ECGs. Group II: Normal pre-TAVR and abnormal subsequent ECGs. Group III. Abnormal baseline and abnormal subsequent ECGs. RESULTS Among 340 TAVR patients, 248 were discharged home with an ACM device. The overall incidence of DACA was 7% (n = 17), of whom 4% (n = 10) required a PPM. Mortality and readmission between discharge and 30 days was 0% and 8.3%, respectively. Stratification of patients identified 96 (38.7%) patients in Group I: 50 (20%) in Group II, and 102 (41%) in Group III. The incidence of DACA requiring a PPM was 0% in Group I, 4% (n = 2) in Group II, and 8.5% (n = 8) in Group III (p < 0.004). CONCLUSIONS In TAVR patients who were discharged home with ACM, none died between discharge and 30-days. For those with normal baseline, perioperative and discharge ECG, there were no events of DACA at 14-days.

Abstract
BACKGROUND Minimally invasive heart valve surgery has previously been shown to be safe and feasible in obese patients. Within this population, we investigated the effect of obesity class on the patient outcomes of minimally invasive aortic valve replacement (mini-AVR). METHODS A single-center retrospective cohort study of consecutive patients with obese body mass indices (BMIs) who underwent mini-AVR between 2012 and 2020. Patients were stratified into three groups according to Centers for Disease Control and Prevention adult obesity classifications: Class I (BMI: 30.0-<35.0), Class II (BMI: 35.0-<40.0), and Class III (BMI ≥ 40.0). The primary outcomes were postoperative length of stay (LOS), 30-day mortality, and direct cost. RESULTS Among 206 obese patients who underwent mini-AVR, LOS (Class I 5 [3-7] vs. Class II 6 [5-7] vs. Class III 6 [5-7] days; p = .056), postoperative 30-day mortality (Class I 2.44% [n = 3] vs. Class II 4.44% [n = 2] vs. Class III 7.89% [n = 3]; p = .200), and costs (Class I $24,118 [$20,237-$29.591] vs. Class II $22,215 [$18,492-$28,975] vs. Class III $24,810 [$20,245-$32,942] USD; p = .683) did not differ between obesity class cohorts. CONCLUSIONS Mini-AVR is safe and feasible to perform for obese patients regardless of their obesity class. Patients with obesity should be afforded the option of minimally invasive aortic valve surgery regardless of their obesity class.

Change in Renal Function and Its Impact on Survival in Chronic Kidney Disease Patients Bridged to Heart Transplantation With a Left Ventricular Assist Device. ASAIO J 2021; 67:1204-1210. [PMID: 33769354 DOI: 10.1097/mat.0000000000001384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022] Open
Abstract
The study investigates the incidence of change in renal function and its impact on survival in renal dysfunction patients who were bridged to heart transplantation with a left ventricular assist device (BTT-LVAD). BTT-LVAD patients with greater than or equal to moderately reduced renal function (estimated glomerular filtration rate [eGFR] ≤ 60 ml/min/1.73 m2) at the time of listing between 2008 and 2018 were identified from a prospectively maintained database of the United Network for Organ Sharing. Patients with a baseline eGFR less than or equal to 15 ml/min/1.73 m2 or on dialysis were excluded. Patients were divided into three groups based on percent change ([Pretransplant eGFR - listing eGFR/listing glomerular filtration rate (GFR)] × 100) in eGFR: Improvement greater than or equal to 10%, no change, decline greater than or equal to 10%, and their operative outcomes were compared. Posttransplant survival was estimated and compared among the three groups with the Kaplan-Meier survival curves and the log-rank test. Cox proportional hazards modeling was used to identify predictors of posttransplant survival. Out of 14,395 LVAD patients, 1,622 (11%) met the inclusion criteria. At the time of transplant, 900 (55%) had reported an improvement in eGFR greater than or equal to 10%, 436 (27%) had no change, and 286 (18%) experienced a decline greater than or equal to 10%. Postoperatively, the incidence of dialysis was higher in the decline than in the unchanged or improved groups (22% vs. 12% vs. 12%; p = 0.002). After a median follow-up of 5 years, there was no difference in posttransplant survival among the stratified groups (improved eGFR: 24.8%, unchanged eGFR: 23.2%, declined eGFR: 20.3%; p = 0.680). On Cox proportional hazard modeling, independent predictors of worse survival were: [hazard ratio: 95% CI; p] history of diabetes (1.43 [1.13-1.81]; p = 0.002) or tobacco use (1.40 [1.11-1.79]; p = 0.005) and ischemic time greater than 4 hours (1.36 [1.03-1.76]; p = 0.027). More than half of the patients with compromised renal function who undergo BTT-LVAD demonstrate an improvement in renal function at the time of transplant. A 10% change in GFR while listed was not associated with worse posttransplant survival.

Abstract
INTRODUCTION Despite the ever-growing number of community onset (CO) Pseudomonas aeruginosa (P. aeruginosa) bacteraemia, there is a dearth of district hospital-based research examining this significant infection, which is associated with high mortality. The objectives of this study were as following: (1) to determine the risk factors of CO P. aeruginosa bacteraemia, (2) to compare the 30-day mortality rate between P. aeruginosa and Escherichia coli bacteraemia and (3) to identify the predictors of 30-day mortality for CO gram negative bacteraemia. METHODS This is a retrospective case control study in Hospital Seri Manjung and Hospital Teluk Intan, Perak, Malaysia. P. aeruginosa bacteraemia cases that occurred between 1st January 2015 to 31st December 2019 were included, whilst E. coli bacteraemia cases that occurred within the same period were recruited successively until 1:2 case control ratio was achieved. Subjects below 12-year-old and those with polymicrobial bacteraemia were excluded. Demographic, clinical and treatment data were collected using pre-tested data collection forms by trained investigators. RESULTS A total of 61 patients with P. aeruginosa bacteraemia and 122 patients with E. coli bacteraemia were included. Recent admission in the earlier three months, regular haemodialysis, immunosuppressive therapy in the past 30 days, chronic wound/pressure sore at presentation and indwelling urinary catheter at presentation were identified as independent predictors of CO pseudomonal bacteraemia. Whilst older age was identified as a negative predictor of CO Pseudomonal bacteraemia (all p<0.05). The 30-day mortality rate was 34.4% in subjects with P. aeruginosa bacteraemia and 27.0% in those with E. coli bacteraemia (p=0.302). Predictors of 30-day mortality for community onset gram negative bacteraemia were as follow: older age, underlying solid tumours, neutropaenia at presentation, in-patient mechanical ventilation, and inpatient nasogastric tube insertion. Unexpectedly, receipt of inappropriate empirical antibiotics which was switched later (delayed and non-delayed switching) was identified as the negative predictors of mortality (all p<0.05). CONCLUSION It is prudent to restrict the usage of empirical anti-pseudomonal antibiotics among individuals at risk as liberal usage of broad-spectrum antibiotics engenders emergence of drug resistant organism, particularly in district setting where community onset pseudomonal bacteraemia remains scarce. Subjects with elevated risk of mortality should receive early escalation of care as per sepsis management guidelines.

Short-term and intermediate outcomes of cardiogenic shock and cardiac arrest patients supported by venoarterial extracorporeal membrane oxygenation. J Cardiothorac Surg 2021; 16:290. [PMID: 34627305 PMCID: PMC8502086 DOI: 10.1186/s13019-021-01674-w] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 09/27/2021] [Indexed: 12/31/2022] Open
Abstract
Background Cardiogenic shock and cardiac arrest are life-threatening emergencies with high mortality rates. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) and extracorporeal cardiopulmonary resuscitation (e-CPR) provide viable options for life sustaining measures when medical therapy fails. The purpose of this study is to determine the utilization and outcomes of VA ECMO and eCPR in patients that require emergent cardiac support at a single academic center. Methods A retrospective chart review of prospectively collected data was performed at an academic institution from January 1st, 2018 to June 30th, 2020. All consecutive patients who required VA ECMO were evaluated based on whether they underwent traditional VA ECMO or eCPR. The study variables include demographic data, duration on ECMO, length of stay, complications, and survival to discharge. Results A total of 90 patients were placed on VA ECMO for cardiac support with 44.4% (40) of these patients undergoing eCPR secondary to cardiac arrest and emergent placement on ECMO. A majority of the patients were male (n = 64, 71.1%) and the mean age was 58.8 ± 15.8 years. 44.4% of patients were transferred from outside hospitals for a higher level of care and 37.8% of patients required another primary therapy such as an Impella or IABP. The most common complication experienced by patients was bleeding (n = 41, 45.6%), which occurred less often in eCPR (n = 29, 58% vs. n = 12, 30%). Other complications included infections (n = 11, 12.2%), limb ischemia (n = 13, 14.4%), acute kidney injury (n = 17, 18.9%), and cerebral vascular accident (n = 4, 4.4%). The length of stay was longer for patients on VA ECMO (32.1 ± 40.7 days vs. 17.7 ± 18.2 days). Mean time on ECMO was 8.1 ± 8.3 days. Survival to discharge was higher in VA ECMO patients (n = 23, 46% vs. n = 8, 20%). Conclusion VA ECMO provided an effective rescue therapy in patients in acute cardiogenic shock with a survival greater than the expected ELSO guidelines of 40%. While the survival of eCPR was lower than expected, this may reflect the severity of patient’s condition and emphasizes the importance of careful patient selection and planning.

Abstract
INTRODUCTION Pseudomonas aeruginosa is known to be the epitome of nosocomial infections associated with high morbidity and mortality. The dearth of local pseudomonal studies has prompted us to conduct this study with the following objectives: (1) to examine the local pseudomonal bacteraemia (PB) epidemiology and clinical characteristics, (2) to compare the 30-day mortality among PB of different onsets and (3) to determine the predictors of 30-day mortality outcome. METHODS This retrospective study was conducted in Hospital Seri Manjung, Perak, Malaysia. All cases of blood culture proven PB that occurred between 1st January 2015 and 31st December 2019 were reviewed. Subjects below 12 year old and whose index blood cultures grew more than one organism were excluded. Demographic, clinical and treatment data were collected using pre-tested data collection forms and analysed using SPSS version 20.0. RESULTS Among the 59 subjects included, healthcare associated (HCA) infections were the most prevalent, next to hospital onset (HO) and community onset (CO) infections. The commonest underlying comorbidities were cardiovascular disease, diabetes mellitus, and chronic kidney disease. Respiratory tract was the most frequently implicated source amongst all, while the urinary tract was more frequently implicated as the source of infection among HCA cases. Seventeen patients were admitted to ICU, and they were predominantly from the HO group. Despite having a higher rate of adequate empirical antibiotics administered, the HO group reported the lowest 30-day survival rate. Multiple logistic regression analysis demonstrated the following were independent predictors of 30-day mortality: requiring mechanical ventilator support, requiring central venous line insertion, not requiring surgery, and receiving inappropriate definite antibiotics. CONCLUSION The incidence of community onset PB was appreciably low, as cases were predominantly HCA and HO in origin. Significant morbidities were observed among pseudomonal infections, with HO infections portending the worst prognosis. Lastly, prognostic factors for determining the mortality caused by PB depended more on the severity of sepsis than the timeliness of appropriate antibiotics.

Abstract
OBJECTIVE The current study aims to report trends of early discharges and identify associated direct costs using a nationally representative database of real-world data experience. METHODS We used nationally weighted data on all patients who had transfemoral transcatheter aortic valve replacement (TAVR) from 2012 to 2017 and discharged alive from the National Inpatient Sample. Patients were divided into early (discharge ≤3 days of admission) and late discharge. Demographics and clinical characteristics were compared. Trends in early discharge and costs associated with admissions were analyzed over the study period. RESULTS Of the 125,188 patients identified, 59,424 (46.9%) were discharged early. The proportion of early discharge increased from 15% in early 2012 to 68% in late 2017 (P < 0.001), with the largest increase occurring from 2014 to 2015. Overall, the average cost of TAVR decreased from $58,408 in 2012 to $49,875 in 2017 (P < 0.001). Compared to late discharge, patients discharged early reported costs savings of ≥$20,000 over the study period. Among the early discharge group, no significant differences in costs were observed for patients discharged on 0 to 1, 2, or 3 days after the procedure. CONCLUSIONS Postoperative length of stay after TAVR has decreased dramatically within the last decade with an observed reduction in procedural costs. While discharge within 3 days appeared cost effective, no differences in costs were noted among patients discharged ≤3 days.

Abstract
Background Cardiac fibromas are rare benign cardiac neoplasms, most frequently occurring in the pediatric population; with very rare cases identified in adults. The tumors are comprised of spindled cells with myofibroblastic ultrastructural features embedded in generally collagenous and elastic stroma. The tumors are intramural in the ventricles, most commonly the left ventricle. Clinical symptoms vary by location and size of tumor and some are asymptomatic. Surgical resection is curative, but rare cases require cardiac transplantation. Case presentation We report an asymptomatic, large, right ventricular fibroma in a 64-year-old woman. The patient underwent open incisional tumor biopsy via lower hemi-sternotomy, followed by complete tumor resection via full sternotomy a week later after confirming the tumor is benign. The tumor was resected using cardiopulmonary bypass, and the defect of right ventricular free wall was repaired using a prosthetic double-patch technique. The postoperative course was uneventful. The patient was discharged to home on day 4 post-complete tumor resection. Conclusion This report expands the existing literature for better comprehension and detection of cardiac fibroma patients and also highlights the various imaging modalities, surgical management, and histological analysis.

Abstract
CREG1 is a small glycoprotein which has been proposed as a transcription repressor, a secretory ligand, a lysosomal, or a mitochondrial protein. This is largely because of lack of antibodies for immunolocalization validated through gain- and loss-of-function studies. In the present study, we demonstrate, using antibodies validated for immunofluorescence microscopy, that CREG1 is mainly localized to the endosomal-lysosomal compartment. Gain- and loss-of-function analyses reveal an important role for CREG1 in both macropinocytosis and clathrin-dependent endocytosis. CREG1 also promotes acidification of the endosomal-lysosomal compartment and increases lysosomal biogenesis. Functionally, overexpression of CREG1 enhances macroautophagy/autophagy and lysosome-mediated degradation, whereas knockdown or knockout of CREG1 has opposite effects. The function of CREG1 in lysosomal biogenesis is likely attributable to enhanced endocytic trafficking. Our results demonstrate that CREG1 is an endosomal-lysosomal protein implicated in endocytic trafficking and lysosomal biogenesis.Abbreviations: AIFM1/AIF: apoptosis inducing factor mitochondria associated 1; AO: acridine orange; ATP6V1H: ATPase H+ transporting V1 subunit H; CALR: calreticulin; CREG: cellular repressor of E1A stimulated genes; CTSC: cathepsin C; CTSD: cathepsin D; EBAG9/RCAS1: estrogen receptor binding site associated antigen 9; EIPA: 5-(N-ethyl-N-isopropyl)amiloride; ER: endoplasmic reticulum; GFP: green fluorescent protein; HEXA: hexosaminidase subunit alpha; IGF2R: insulin like growth factor 2 receptor; LAMP1: lysosomal associated membrane protein 1; M6PR: mannose-6-phosphate receptor, cation dependent; MAPK1/ERK2: mitogen-activated protein kinase 1; MTORC1: mechanistic target of rapamycin kinase complex 1; PDIA2: protein disulfide isomerase family A member 2; SQSTM1/p62: sequestosome 1; TF: transferrin; TFEB: transcription factor EB.

Abstract
BACKGROUND Octogenarians undergoing cardiac surgery have higher mortality than their younger counterparts. OBJECTIVES To determine if various risk factors have the same effect on mortality in octogenarians as in younger patients. METHODS The National Inpatient Sample data set from 2004 to 2014 was queried to select patients aged 65 years and older who underwent either coronary artery bypass grafting (CABG), valvular heart surgery (VHS), or both (CABG + VHS) within 10 days of hospital admission. The patients were divided into two groups 65-79 years and 80 years and greater. Hospital mortality, patient demographics, comorbidities, and type of hospital admission was evaluated and compared using χ2 and multivariable logistic regressions. RESULTS About 397,713 patients were identified including 86,345 (21.7%) aged 80 and above. Octogenarians had higher in-hospital mortality for all procedures: CABG (4.94% vs. 2.39%, p < .001), VHS (5.49% vs. 4.08%, p < .001), and CABG + VHS (7.59% vs. 5.95%, p < .001), and this relationship persisted when gender, race, comorbidities, and type of hospital admission were controlled for: CABG (odds ratio [OR] = 1.71; 95% confidence interval [CI] 1.62-1.81); VHS (OR = 1.18; 95% CI 1.11-1.27); and CABH + VHS (OR = 1.17; 95%CI 1.10-1.26). Female gender, renal, or heart failure, nonelective admission, and CABG + VHS were associated with increased risk of in-hospital mortality. Octogenarians had higher rates of these factors (p < .001). The effect size of renal and heart failure and type of surgery was smaller for octogenarians. CONCLUSIONS Octogenarians undergoing cardiac surgery have higher rates of nonelective admissions, renal and heart failure, and female gender, which are most strongly associated with in-hospital mortality. Differing effect sizes suggest that certain risk factors, such as renal and heart failure, contribute more to mortality in younger patients.

Abstract
INTRODUCTION The Malaysian Association of Clinical Biochemists (MACB) established a Task Force for Chronic Kidney Disease. A survey was undertaken by the Task Force on the reporting of estimated glomerular filtration rate (eGFR) and urine albumin by hospital laboratories in Malaysia in both the government and private sectors. MATERIALS AND METHODS An e-mail invitation to participate in an online survey was sent to hospital laboratories in Malaysia (n=140). Questions regarding methods for measuring creatinine, equations for calculating eGFR, eGFR reporting, the terminology used in reporting urine albumin, types of samples and the cut-off values used for normal albuminuria. RESULTS A total of 42/140 (30%) laboratories answered the questionnaire. The prevalent method used for serum creatinine measurement was the Jaffé method (88.1%) traceable to isotope-dilution mass spectrometry. eGFR was reported along with serum creatinine by 61.9% of laboratories while 33.3% of laboratories report eGFR on request. The formula used for eGFR reporting was mainly MDRD (64.3%) and results were reported as exact numbers even when the eGFR was <60 ml/min/1.73m2. The term microalbumin is still used by 83.3% of laboratories. There is a large heterogeneity among the labs regarding the type of sample recommended for measuring urine albumin, reference interval and reporting units. CONCLUSION It is evident that the laboratory assessment of chronic kidney disease in Malaysia is not standardised. It is essential to provide a national framework for standardised reporting of eGFR and urine albumin. Recommendations developed by the MACB CKD Task Force, if adopted by all laboratories, will lead to a reduction in this variability.

Abstract
OBJECTIVE We investigated health and healthcare disparities in the treatment of aortic stenosis with transcatheter aortic valve replacement (TAVR) and how they affect resource utilization and costs. METHODS We retrospectively reviewed all patients who were discharged alive after TAVR between 2012 and 2017 from the National Inpatient Sample. Patients were stratified by race and outcomes investigated were in-hospital complications, total procedural costs, and resource utilization. High resource utilization (HRU) was defined as length of stay (LOS) ≥7 days or discharge to a nonhome location. Multivariable regression models were used to identify predictors of HRU. RESULTS TAVR patients (N = 29,464) were stratified into Caucasians (n = 25,691), others (n = 1,274), Hispanics (n = 1,267), and African Americans (AA, n = 1,232). More AA and Hispanics had TAVR at urban teaching centers (P = 0.003) and were less likely to be Medicare beneficiaries (P < 0.001). Distribution of TAVR patients in the lowest income quartile showed AA (50%) versus Caucasian (20%) versus Hispanic (33%, P < 0.001). In-hospital complications were higher among Hispanics and AA than Caucasians with prolonged LOS, procedural costs, and HRU. On multivariable analysis, independent predictors of HRU were TAVR year (P < 0.001), advanced age (P < 0.001), female sex (P < 0.001), non-Caucasian race (P = 0.038), history of coronary artery bypass grafting (P < 0.001), smoking (P < 0.001), chronic lung disease (P = 0.003), stroke (P < 0.001), and lowest income quartile (P = 0.002). CONCLUSIONS There exist significant healthcare and health disparities among patients undergoing TAVR in the United States. Consequently, this unequal access to care and determinants of heath translate into higher resource utilization and costs.

Abstract
Background The optimal cannulation site for repair of type A aortic dissection remains controversial. The concern for Malperfusion syndrome has initiated a national trend away from femoral cannulation to axillary artery and direct ascending aortic cannulation. The purpose of this study was to report a single center experience with femoral artery cannulation for the repair of a type A dissection. Methods A retrospective study was performed on 52 patients who underwent surgical repair for a type A dissection between January 1st, 2012 and June 30th, 2019 at a single institution. Of the 52 patients analyzed, 35 (67.3%) underwent femoral artery, 11 (21.2%) direct ascending aortic, and 6 (11%) axillary artery cannulation for arterial access. Deep hypothermic circulatory arrest was used in all the patients. Rates of postoperative complication and mortality were reported. Results The mortality and bleeding rates for all the patients undergoing repair of the type A dissection repairs were 27% (14/52) and 19% (10/52), respectively. Cardiopulmonary bypass was established in 100% of the patients that had femoral arterial cannulation. There were no complications specifically related to femoral arterial cannulation nor the axillary or direct aortic approach. Specifically, there was no episodes of malperfusion syndrome, bleeding, or injury with femoral artery cannulation. Bleeding rates were higher in cases that proceeded with a femoral (13%) versus alternate (6%) approach however; neither of the bleeding was related to the cannulation site. None of the mortalities identified were directly attributable to the cannulation approach in each case. Conclusions Despite the recent shift away from femoral cannulation, the results of the study show that femoral artery cannulation is safe and produces excellent results for establishing cardiopulmonary bypass. The concerns for malperfusion syndrome related to femoral cannulation were not seen.

The role of the axillary Impella 5.0 device on patients with acute cardiogenic shock. J Cardiothorac Surg 2020; 15:218. [PMID: 32795321 PMCID: PMC7427736 DOI: 10.1186/s13019-020-01251-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 07/21/2020] [Indexed: 11/10/2022] Open
Abstract
Background Acute cardiogenic shock is associated with high mortality rates. The Impella device is a microaxial left ventricular assist device that can be inserted through the axillary artery. The purpose of our study is to determine the role of the Axillary Impella devices on patients with acute cardiogenic shock. Methods A retrospective chart review was conducted to identify patients who underwent Axillary Impella device placement for acute cardiogenic shock from January 1st, 2014 to September 30th, 2018 at a single institution. In-patient records were examined to determine duration of device, length of stay (LOS), postoperative complications, and 30-day in-hospital mortality. Results A total of 40 patients, who were primarily men (N = 29) with a mean age of 61.2 ± 10.7 years old, underwent Axillary Impella placement for cardiogenic shock. The primary reasons for implant were (1) required upgraded support from an Impella CP or intra-aortic balloon pump (iabp) to Impella 5.0, (2) to treat left ventricular (LV) distention for patients on extracorporeal mechanical oxygenation (ECMO), and (3) to provide longer term support and allow for mobilization of the patients in whom a device was already indwelling. Twenty-three of the patients had previous devices already in place including a Femoral Impella CP device or an iabp and 9 patients were on ECMO support. The duration of the device was 21.05 ± 17 days with the LOS of 40.8 ± 28 days for those patients. Seventeen of the patients went on to additional surgery including (1) Heartmate 3 device placement (N = 6), (2) other cardiac procedures such as surgical revascularization (N = 9), and orthotopic heart transplantation (N = 2). A total of 21 patients of the 40 (52%) died during their hospitalization with 7 patients (17%) having complications related to the Impella device. These complications included right arm ischemia or neuropathy (N = 3) and Impella malfunction requiring device replacement (N = 4). The majority of these devices were placed in the right axillary artery (N = 38) versus the left axillary artery (N = 2). Conclusions A total of 58% (N = 23) of the study patients had previous mechanical support and 23% (N = 9) were on ECMO demonstrating the severity of disease and accounting for the high mortality. The Axillary Impella device allows for a minimally invasively placed device that is durable with a mean duration of 3 weeks. The Axillary artery Impella 5.0 provides upgraded full cardiac support while allowing for mobilization of the patient. In addition, it treats LV distention in patients on ECMO while avoiding sternotomy. Finally, the Axillary Impella provides time for decision making for explant, additional therapy with either long-term devices or orthotopic heart transplant.

PTEN suppresses epithelial-mesenchymal transition and cancer stem cell activity by downregulating Abi1. Sci Rep 2020; 10:12685. [PMID: 32728066 PMCID: PMC7391766 DOI: 10.1038/s41598-020-69698-1] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Accepted: 07/14/2020] [Indexed: 02/07/2023] Open
Abstract
The epithelial–mesenchymal transition (EMT) is an embryonic program frequently reactivated during cancer progression and is implicated in cancer invasion and metastasis. Cancer cells can also acquire stem cell properties to self-renew and give rise to new tumors through the EMT. Inactivation of the tumor suppressor PTEN has been shown to induce the EMT, but the underlying molecular mechanisms are less understood. In this study, we reconstituted PTEN-deficient breast cancer cells with wild-type and mutant PTEN, demonstrating that restoration of PTEN expression converted cancer cells with mesenchymal traits to an epithelial phenotype and inhibited cancer stem cell (CSC) activity. The protein rather than the lipid phosphatase activity of PTEN accounts for the reversal of the EMT. PTEN dephosphorylates and downregulates Abi1 in breast cancer cells. Gain- and loss-of-function analysis indicates that upregulation of Abi1 mediates PTEN loss-induced EMT and CSC activity. These results suggest that PTEN may suppress breast cancer invasion and metastasis via dephosphorylating and downregulating Abi1.

Abstract
Aims This study investigated outcomes after continuous flow left ventricular assist device (CF‐LVAD) implantation as bridge to heart transplantation (BTT) in advanced heart failure patients stratified by race. Methods and results De‐identified data from the United Network for Organ Sharing database was obtained for all patients who had a CF‐LVAD as BTT from 2008 to 2018. Patients were stratified into four groups on the basis of ethnicity [Caucasian, African American (AA), Hispanic, and others (Asian, Pacific Islanders, and American Indian)]. Outcomes investigated were waitlist mortality or delisting and post‐transplant 5 year survival. Cox proportional hazards modelling was used to identify independent predictors of waitlist mortality or delisting and post‐transplant survival. We used Kaplan–Meier survival curves and the log‐rank test to estimate and compare survival among groups. A total of 14 234 patients who had CF‐LVADs as BTT were identified. Of these, 64% (n = 9058) were Caucasians, 26% (n = 3677) were AA, 7% (n = 997) were Hispanic, and 3% (n = 502) had a different race. Compared with Caucasian, AA, and Hispanic patients had higher body mass indexes and a lower level of education and are more likely to be public health insurance beneficiaries. There was a significantly lower incidence of transplantation in AAs compared with Caucasians, Hispanics, and others at 12, 24, and 60 months, respectively (Gray's test, P < 0.001). The AA race was a significant predictor of waitlist mortality or delisting owing to worsening clinical status [hazard ratio, 95% confidence interval: 1.10 (1.01 to 1.16; P < 0.001)]. Among those who were successfully BTT, risk‐adjusted post‐transplant survival was similar among the four groups (log‐rank test: P = 0.589). Conclusions Disparities exist among different races that receive a CF‐LVAD as a BTT. These disparities translate into increased waitlist morbidity and mortality but not long‐term post‐transplant survival among those who successfully reach transplant.

Abstract
OBJECTIVE As the population ages, increasing number of older patients are undergoing adult cardiac surgery. The purpose of the study is to assess the impact of age on postoperative outcomes in patients that undergo coronary artery bypass grafting (CABG). METHODS Patients that are ≥70 years old who underwent CABG were selected from the Nationwide/National Inpatient Sample from 2010 to 2015 using ICD-9-CM diagnosis and procedure codes. The patients who were 70-79 years old were compared to patients aged 80-89 years old to determine if the age difference of the patients had an impact on surgical outcomes. In addition, a secondary endpoint is to compare surgical outcomes between the 2 genders of the patients 80-89 years old. The rates of postoperative complications, and mortality were compared. RESULTS A total of 67,568 patients were identified who were ≥ 70 years old and underwent CABG. Compared to the Septuagenarians, the Octogenarians were more likely to develop cardiac complications (OR [odds ratio] =1.20, 95% CI [confidence interval] 1.12-1.23. They were also more likely to develop renal complications (P < 0001), and respiratory complications (P < 0001). The Octogenarians were also more likely to bleed postoperatively (P < 0.0001) and have a higher mortality (P < 0001). Furthermore, the female Octogenarians had a higher mortality (OR 1.25 95% CI 1.07-1.46) compared to males in the same age group. CONCLUSIONS The patients who were ≥ 80-89 years old had worse postoperative outcomes. The Octogenarians who were females had a higher mortality compared to their male counterparts.

Abstract
Objectives The optimal timing of coronary artery bypass grafting (CABG) in patients with ST elevated acute myocardial infarction (STEMI) is unclear. The purpose of the study is to evaluate and compare the outcomes in STEMI patients who underwent CABG within the various time intervals within the first 7 days of either emergent or urgent hospital admission. Methods Patients aged 30 years old and older diagnosed with STEMI who underwent CABG within first 7 days after non-elective hospital admission were selected from the National Inpatient Sample 2010–2014 using the appropriate ICD-9-CM diagnosis and procedure codes. These patients were divided into 3 cohorts based on timing of surgery: within 24 h (group A), 2nd-3rd day (group B), and 4th–7th day (group C). The rates of postoperative complications, mortality, and postoperative hospital length of stay (LOS) were compared using the Chi-square test, multivariable logistic regression analysis, and Wilcoxon rank sum test. Results A total of 5963 patients were identified: group A = 28.5%, group B = 36.1%, group C = 35.4%. Mean age overall was 63.1 ± 11.1 years; 76.9% were males and 72.9% were whites. Compared to groups B and C, patients in group A were more likely to develop cardiac complications (OR [odds ratio] =1.33, 95%CI [confidence interval] 1.12–1.59 and OR = 1.39, 95%CI 1.17–1.67, respectively) and respiratory complications (OR = 1.31, 95%CI 1.13–1.51 and OR = 1.53, 95%CI 1.32–1.78, respectively). They were also more likely to have renal complications (OR = 1.31, 95%CI 1.11–1.54) and bleeding (OR = 1.20, 95%CI 1.05–1.37) than patients in group B and had a similar tendency compared to group C. We did not find significant differences in the above complications between groups B and C. Postoperative stroke and sternal wound infection rates were similar between all three groups. In-hospital mortality was also higher in group A (8.2%) compared to group B (3.5%) and group C (2.9%, P < 0.0001 for both); differences between groups B and C were not significant. This was confirmed in the multivariable logistic regression analysis with controlling for age, gender, race, the Elixhauser Comorbidity Index, and complications (group A vs B: OR = 1.85, 95%CI 1.52–2.25; group A vs C: OR = 2.21; 95%CI 1.82–2.68). Patients in group A had a significantly longer postoperative LOS (median 7 days with IQR [interquartile range] 5–10 days) compared to those in group B (median 6 days, IQR 5–8 days) and group C (median 6 days, IQR 4–8 days; P < 0.0001 for both). Conclusions The results of this study show that despite the urgency and severity of STEMI, patients who undergo CABG within the first 24 h after non-elective hospital admission have increased hospital morbidity and mortality. These findings suggest that a delay in surgery beyond the first 24 h may be beneficial to patient outcomes. Furthermore, there is a significant cost effectiveness when the patients delay surgery because the hospital length of stay is reduced as well as the subsequent hospital costs.

Abstract
BACKGROUND To examine the incidence and trends of peri-procedural complications after TAVR and their impact on resource utilization. METHODS The incidence of complications by type [acute kidney injury (AKI), permanent pacemaker (PPM), vascular, paravalvular leak, in-hospital mortality, others] was calculated for TAVR patients at a high-volume center between 2012 and 2018. Clinical data were matched with hospital-billing data of patients. Trends in high resource utilization (discharge to a rehabilitation facility or PLOS >7 days) (HRU) and complication rates were assessed. Multivariable logistic regression models were used to determine predictors of HRU. RESULTS Out of 1163 patients, 966 (83%) had no complications, others in 95 (8%), PPM in 56 (5%), AKI alone in 32 (3%), vascular in 31 (3%), in-hospital mortality in 28 (2%) and PVL in 10 (1%). A significant decreasing trend in the incidence of complications (29% vs 10%; p trend <0.001) and HRU (75% vs 12%; p trend <0.001) was observed between 2012 and 2018 respectively. Mean ± SD direct procedure cost of having a complication was $58,234 ± $24,568, was associated with an incremental cost of $10, 649 and a prolonged stay of 3-days. On multivariable logistic regression analysis, PPM, vascular complications, high STS risk score, NYHA class III/IV, frailty and ≥ moderate tricuspid regurgitation were significantly associated with HRU. TAVR year was protective against HRU. CONCLUSIONS We established that, post-TAVR resource utilization and morbidity is high among frail and patients with higher STS risk scores. However, these rates decrease over time with experience.

Abstract
BACKGROUND This study aims to investigate the association between social behaviors of increased-risk donors (IRD) and recipient outcomes after heart transplantation. METHODS The United Network for Organ Sharing (UNOS) database was queried to identify patients who received a heart transplant between 2004 and 2015. Patients were grouped based on donor's risk status (IRD vs standard risk donor [SRD]). Recipients of IRD were categorized based on donor social behaviors (SB), and recipient survival was assessed. Cox regression analysis was used to identify associations between SB of donors and recipient survival. RESULTS Out of 22 333 heart transplantations performed during the study period, 2769 (12%) received an IRD graft with the following SB: Unprofessional tattoos or piercings (n = 1722) (63%), cocaine use (n = 916) (33%), heavy smoking (n = 437) (16%), and heavy alcohol abuse (n = 610) (22%). Viral screens detected 72(3%) hepatitis B virus (HBV) positive and 12 (0.4%) hepatitis C virus (HCV) positive at donation. There was no difference in recipient survival based on both donor risk and their social behaviors. Cox regression analysis found only donor HCV infection and non-identical ABO mismatch to be associated with poor recipient survival among recipients of IR grafts. CONCLUSION Cardiac allografts from IRD, serologically negative for viruses, can safely be used. There is no association between social behaviors of IRD and recipient survival.

Abstract
Significant aortic calcification is a known sequelae of homograft aortic root replacement and creates a treatment challenge if these patients require cardiac reintervention. The standard surgical option for patients requiring an aortic valve replacement in the setting of a calcified aortic homograft has been a Bentall procedure, which is high-risk with extended cross-clamp, cardiopulmonary bypass and operative times. We present a patient with a severely calcified aortic homograft who underwent successful valve replacement using a rapid deployment aortic valve leaving the aortic root and arch intact and avoiding the more extensive redo aortic root replacement. Similar cases in the literature are rare.

Abstract
Objective The treatment of active infective endocarditis (IE) presents a clinical dilemma with uncertain outcomes. This study sets out to determine the early and intermediate outcomes of patients treated surgically for active IE at an academic medical center. Methods A retrospective chart review was conducted to identify patients who underwent surgical intervention for IE at our institution from July 1st, 2011 to June 30th, 2018. In-patient records were examined to determine etiology of disease, surgical intervention type, postoperative complications, length of stay (LOS), 30-day in-hospital mortality, and 1-year survival. Results Twenty-five patients underwent surgical intervention for active IE. The average age of the patients was 47 ± 14 years old and most of the patients were male (N = 15). The majority of the patients had the mitral valve replaced (N = 10), with the remaining patients having tricuspid (N = 8) and aortic (N = 7) valve replacements. The etiology varied and included intravenous drug use (IVDU), and presence of transvenous catheters. The 30-day in-hospital mortality was 4% with 1 patient death and the 1-year survival was 80%. The average LOS was 27 days ±15 and the longest LOS was 65 days. Conclusions Surgical management of IE can be difficult and challenging however mortality can be minimized with acceptable morbidity. The most common complication was CVA. The average LOS is longer than traditional adult cardiac surgery procedures and the recurrence rate of valvular infection is not minimal especially if the underlying etiology is IVDU.

Abstract
Purpose Cardiothoracic surgeons are frequently called upon to perform surgical pericardial drainage procedures (pericardial window) for pericardial effusions. These procedures have therapeutic value, but the diagnostic value of such procedures is debated. We set out to determine the sensitivity of pericardial drainage to detect the disease when cytology, microbiology, and pathology are evaluated. Methods A retrospective chart review of patients who underwent pericardial windows from 1 July 2011 to 1 January 2018 at a single academic institution was conducted. All patients who had undergone a recent trauma or cardiac procedure were excluded. Cytology, microbiology, and pathology were examined. The charts were then carefully reviewed to determine if a clinical diagnosis was reached. Sensitivity was then calculated for all diseases and for those that should have been able to be detected. Results One hundred sixty‐two patients who had undergone a pericardial drainage procedure were identified; 49 patients were excluded for recent cardiac procedure or trauma. Of the 113 patients who met our inclusion criteria, 56 patients (49.6%) were female with a mean age of 59.7 ± 15.1 years. A diagnosis based on the pathology, microbiology, or cytology was obtained for 27 patients. The most common pathologies detected were adenocarcinoma (11), bacteremia (9), and small cell lung cancer (3); 56 patients had underlying pathologies that would have been possible to detect with either pathology, microbiology, or cytology. The most common detectable diagnoses were adenocarcinoma (20), bacteremia (12), and lymphoma (7). The most common undetectable diagnoses were idiopathic (17), cardiorenal fluid overload (17), and viral (11). The sensitivity of a pericardial drainage procedure for detecting disease was 0.24 for all cases, and 0.48 when restricted to cases where a detectable disease was present. Conclusion Cytology, microbiology, and pathology for pericardial drainage procedures were unable to detect a diagnosis for 76% of all cases and greater than 50% of cases with the theoretically detectable disease. Pericardial drainage procedures have a clear therapeutic value, but they have limited diagnostic utility.
