RESUMO
OBJECTIVE: To assess whether bioimpedance spectroscopy analysis (BIA) can be used as a tool to guide postoperative fluid management in patients undergoing cardiac surgery. DESIGN: An observational study. SETTING: A single tertiary hospital. PARTICIPANTS: Patients who underwent cardiac surgery with cardiopulmonary bypass between June and November 2023 who were able to undergo BIA measurements. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Correlations between BIA measurements of extracellular fluid (ECF) and total body water (TBW) volumes and daily changes in weight and 24-hour net intake and output (I/O) of fluids were assessed. Correlations between predischarge ECF volume as a percentage of TBW volume (ECF%TBW) and predischarge pro-B-type natriuretic peptide (Pro-BNP) levels and readmissions were analyzed. Changes in daily ECF volume significantly correlated with daily weight changes (p < 0.01) and 24-hour I/O (p < 0 .01). TBW volume significantly correlated with daily weight changes (p < 0.01) and with 24-hour I/O (p = 0.04). Daily weight changes did not correlate with 24-hour I/O (p = 0.06). The patients with predischarge ECF%TBW(%) greater than or equal to 51 had significantly higher predischarge Pro-BNP than those with ECF%TBW(%) less than 51 (p < 0.01). Patients who had heart failure revisits or admissions after discharge had a higher predischarge ECF%TBW(%) on index admission compared with patients who did not have heart failure readmissions (p = 0.01). CONCLUSIONS: BIA measurements in postoperative cardiac surgery patients may be a valuable tool to quantitatively determine fluid status to help guide fluid management in this patient population. Further studies validating the use of BIA for postoperative care in this population are warranted.
RESUMO
OBJECTIVES: To compare the outcomes of factor eight inhibitor bypassing activity (FEIBA) versus fresh frozen plasma (FFP) as the primary treatment for postoperative coagulopathy in patients undergoing cardiac surgery. DESIGN: A retrospective, propensity-matched study. SETTING: A single, tertiary hospital. PARTICIPANTS: Patients who underwent noncoronary cardiac surgery with cardiopulmonary bypass between 2015 and 2023. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We stratified patients into 2 groups based on whether they received intraoperative FFP or FEIBA; cases using both were excluded. We analyzed 434 cases, with 197 receiving FFP and 237 receiving FEIBA. After propensity matching, there was no significant difference in the proportion of the patients who required packed red blood cell transfusions (p = 0.08). However, of those who required packed red blood cell transfusions, patients in the FEIBA group required significantly fewer units of packed red blood cells (p < 0.001). Significantly fewer patients in the FEIBA group required platelet (p < 0.001) and cryoprecipitate (p < 0.001) transfusions. The FEIBA group showed decreased prolonged postoperative intubation (p = 0.05), decreased intensive care unit length of stay (p = 0.04), and lower 30-day readmission rates (p = 0.03). There were no differences in the rates of thrombotic complications between the 2 cohorts. CONCLUSIONS: In the initial treatment of postcardiopulmonary bypass coagulopathy, FEIBA may be more effective than FFP in decreasing blood product transfusions and readmission rates. Further studies are needed to explore the potential routine use of FEIBA as first-line agent in this patient population.

OBJECTIVE: Oxygen consumption (VO2), carbon dioxide generation (VCO2), and respiratory quotient (RQ), which is the ratio of VO2 to VCO2, are critical indicators of human metabolism. To seek a link between the patient's metabolism and pathophysiology of critical illness, we investigated the correlation of these values with mortality in critical care patients. METHODS: This was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Age 18 years or older healthy volunteers and patients who underwent mechanical ventilation were enrolled. A high-fidelity automation device, which accuracy is equivalent to the gold standard Douglas Bag technique, was used to measure VO2, VCO2, and RQ at a wide range of fraction of inspired oxygen (FIO2). RESULTS: We included a total of 21 subjects including 8 post-cardiothoracic surgery patients, 7 intensive care patients, 3 patients from the emergency room, and 3 healthy volunteers. This study included 10 critical care patients, whose metabolic measurements were performed in the ER and ICU, and 6 died. VO2, VCO2, and RQ of survivors were 282 +/- 95 mL/min, 202 +/- 81 mL/min, and 0.70 +/- 0.10, and those of non-survivors were 240 +/- 87 mL/min, 140 +/- 66 mL/min, and 0.57 +/- 0.08 (p = 0.34, p = 0.10, and p < 0.01), respectively. The difference of RQ was statistically significant (p < 0.01) and it remained significant when the subjects with FIO2 < 0.5 were excluded (p < 0.05). CONCLUSIONS: Low RQ correlated with high mortality, which may potentially indicate a decompensation of the oxygen metabolism in critically ill patients.

OBJECTIVES: Enhanced recovery pathway (ERP) refers to extensive multidisciplinary, evidence-based pathways used to facilitate recovery after surgery. The authors assessed the impact that limited ERP protocols had on outcomes in patients undergoing cardiac surgery at their institution. DESIGN: A retrospective cohort study. SETTING: This study was a single-institution study conducted at a university hospital. PARTICIPANTS: Patients undergoing open adult cardiac surgery. INTERVENTIONS: Enhanced recovery pathways limited to preoperative, intraoperative, and postoperative management of pain, atrial fibrillation prevention, and nutrition optimization were implemented. MEASUREMENTS AND MAIN RESULTS: A total of 1,058 patients were included in this study. There were 374 patients in each pre- and post-ERP cohort after propensity matching, with no significant baseline differences between the 2 cohorts. Compared to the matched patients in the pre-ERP group, patients in the post-ERP group had decreased total ventilation hours (6.8 v 7.8, p = 0.006), less use of postoperative opioid analgesics as determined by total morphine milligram equivalent (32.5 v 47.5, p < 0.001), and a decreased rate of postoperative atrial fibrillation (23.3% v 30.5%, p = 0.032). Post-ERP patients also experienced less subjective pain and postoperative nausea and drowsiness as compared to their matched pre-ERP cohorts. CONCLUSIONS: Limited ERP implementation resulted in significantly improved perioperative outcomes. Patients additionally experienced less postoperative pain despite decreased opioid use. Implementation of ERP, even in a limited format, is a promising approach to improving outcomes in patients undergoing cardiac surgery.

OBJECTIVE: Using a system, which accuracy is equivalent to the gold standard Douglas Bag (DB) technique for measuring oxygen consumption (VO2), carbon dioxide generation (VCO2), and respiratory quotient (RQ), we aimed to continuously measure these metabolic indicators and compare the values between post-cardiothoracic surgery and critical care patients. METHODS: This was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Age 18 years or older patients who underwent mechanical ventilation were enrolled. RESULTS: We included 4 post-surgery and 6 critical care patients. Of those, 3 critical care patients died. The longest measurement reached to 12 h and 15 min and 50 cycles of repeat measurements were performed. VO2 of the post-surgery patients were 234 ± 14, 262 ± 27, 212 ± 16, and 192 ± 20 mL/min, and those of critical care patients were 122 ± 20, 189 ± 9, 191 ± 7, 191 ± 24, 212 ± 12, and 135 ± 21 mL/min, respectively. The value of VO2 was more variable in the post-surgery patients and the range of each patient was 44, 126, 71, and 67, respectively. SOFA scores were higher in non-survivors and there were negative correlations of RQ with SOFA. CONCLUSIONS: We developed an accurate system that enables continuous and repeat measurements of VO2, VCO2, and RQ. Critical care patients may have less activity in metabolism represented by less variable values of VO2 and VCO2 over time as compared to those of post-cardiothoracic surgery patients. Additionally, an alteration of these values may mean a systemic distinction of the metabolism of critically ill patients.

The Hospital Consumer Assessment of Health Care Providers and Systems (HCAHPS) is a survey tool that quantifies patient satisfaction after hospitalization. We sought to interrogate our HCAHPS results in order to identify any association between preoperative health, type of operation, and postoperative outcomes, with patient satisfaction after cardiac surgery. Of 12,572 patients who underwent cardiac surgery between December 2012 and December 2019, 2587 patients (20.6%) completed the HCAHPS survey. Patient satisfaction was quantified using HCAHPS responses, focused on 'top-box' rating in nursing care, physician care, hospital environment, and overall hospital rating, as primary endpoints. Multivariable logistic regression was used to identify those variables associated with top-box scores. Elevated patient risk, as measured by the Society of Thoracic Surgeons (STS) risk score in 2112 patients, was predictive of lower rates of top-box responses in nursing care (OR 0.963, Pâ¯=â¯0.003), physician care (OR 0.96, Pâ¯=â¯0.002), and overall hospital rating (OR 0.97, Pâ¯=â¯0.007). Major postoperative complications were associated with lower patient satisfaction for nursing care (OR 0.67, P = 0.038), physician care (OR 0.59, P = 0.012), and overall hospital rating (OR 0.64, P = 0.035); length of stay ≥ 6 days was associated with increased patient satisfaction for nursing care (OR 1.45, P < 0.001). Increased preoperative risk and postoperative complications are associated with lower rates of top-box patient satisfaction scores after cardiac surgery. When assessing patient satisfaction after cardiac surgery, we suggest that a preoperative risk profile be considered.

Background: Perioperative bleeding and transfusion have been associated with major morbidity and mortality after cardiac surgery. As concerns remain regarding potential graft thrombosis following administration of a prothrombin factor concentrate, the use of factor eight inhibitor bypassing activity (FEIBA) in managing refractory postoperative bleeding has never been evaluated in patients undergoing isolated coronary artery bypass grafting (CABG). Objectives: We aimed to examine the safety of FEIBA in patients undergoing isolated CABG, with respect to 30-day mortality, perioperative outcomes, and thrombotic complications. Methods: A retrospective review was undertaken of all consecutive patients who had undergone isolated on-pump CABG between January 2015 and December 2019 at North Shore University Hospital. Patients requiring intraoperative extracorporeal membrane oxygenator support were excluded. Patients were divided into two groups, dependent upon whether they received FEIBA (n = 63) versus no FEIBA (n = 2493). A 1:5 propensity match analysis was employed, and patients were analyzed with respect to thrombotic complications, reintervention for myocardial ischemia, and short-term clinical outcomes. Results: There was no difference in 30-day mortality between the two cohorts. There was also no significant difference in a composite of thrombotic complications (composed of deep vein thrombosis, pulmonary embolism, and stroke) between the two groups. Similarly, there was no significant difference in the requirement for postoperative reintervention for myocardial ischemia between patients who received FEIBA versus those who did not. Conclusions: Factor eight inhibitor bypassing activity may be safe when used as rescue therapy for refractory bleeding following isolated CABG.
RESUMO
BACKGROUND: The following cell cycle arrest urinary biomarkers, tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP-7), have been used for early detection of acute kidney injury (AKI) in critically ill patients. The purpose of this study is to validate the use of these urinary biomarkers in patients undergoing open heart surgery. MATERIALS AND METHODS: In a single-center prospective observational study, urine samples were collected in 108 consecutive patients who underwent open heart surgery immediately after separation from cardiopulmonary bypass and on postoperative day 1, and were sent for the biomarker [TIMP-2]*[IGFBP7] analysis. Acute kidney injury was defined based on KDIGO criteria, and levels of [TIMP-2]*[IGFBP7] were analyzed for the ability to predict AKI. RESULTS: Of the 108 patients, 19 (17.6%) patients developed postoperative AKI within 48 hours of surgery. At the threshold of > 0.3 (ng/mL)2/1,000, post-cardiopulmonary bypass [TIMP-2]*[IGFBP-7] had a sensitivity of 13% and specificity of 82% for predicting postoperative AKI. Postoperative day-1 [TIMP-2]*[IGFBP-7] had a sensitivity of 47% and a specificity of 59% for predicting postoperative AKI. There were no differences in [TIMP-2]*[IGFBP-7] values at either timepoint between patients who developed postoperative AKI as compared to those who did not. CONCLUSION: Urinary [TIMP-2]*[IGFBP7] was not predictive of the risk of AKI after cardiac surgery in this single-center study population.

OBJECTIVE: Transcathether edge-to-edge mitral valve repair (TEER) has been shown to be an effective treatment for secondary mitral regurgitation (MR). However, the outcomes of TEER in patients with severe cardiomyopathy is less clear. The objective of this study is to determine the outcomes of such patients who underwent TEER at our institution. METHODS: A retrospective review of patients with severe cardiomyopathy, defined as ejection fraction ≤30% or the requirement of inotropic support preoperatively, undergoing TEER for secondary MR at our institution from 11/2016 to 11/2020 was performed. Univariate analysis associating preoperative characteristics with our primary endpoint of 1-year death or orthotopic heart transplant (OHT) was performed. Kaplan-Meier analysis was conducted for the composite outcome of death or OHT, as well as for heart failure-related readmission. Finally, an assessment of changes in MR severity from the preoperative, to immediate postoperative period, to 30-day postoperative period was conducted. RESULTS: There were 48 patients identified. Median age was 74.5 years (IQR 65.5-79.5), median ejection fraction was 21.5% (IQR 16.0-27.5), and 81.4% of patients had severe or torrential mitral regurgitation preoperatively. The composite endpoint of 1-year mortality or OHT occurred in 15 of 48 patients (31.3%, 14 deaths and 1 OHT). One-year heart failure readmission rate was 47.9%. Mortality or OHT at 2 years occurred in 45.8%. CONCLUSION: Patients at extremes of heart failure who underwent TEER had poor outcomes when assessed at 1-year. Our study may suggest that the results of cardiovascular outcomes assessment of the mitraclip percutaneous therapy for heart failure patients with secondary mitral regurgitation may not be applicable to patients with severe cardiomyopathy.

Objective: Acute type A aortic dissection (ATAAD) is a surgical emergency with significant morbidity and mortality, as well as significant center-level variation in outcomes. Our study aims to leverage a nationally representative database to assess contemporary in-hospital outcomes in surgical repair of ATAAD, as well as the association of age and sex with outcomes. Methods: The National Inpatient Sample was queried to identify hospital discharge records of patients aged ≥18 years who underwent urgent surgical repair of ATAAD between 2017 and 2018. Patients with a diagnosis of thoracic aortic dissection, who underwent surgical intervention of the ascending aorta, were identified. Patient demographics were assessed, and predictors of in-hospital mortality were identified. Results: We identified 7805 weighted cases of surgically repaired ATAAD nationally, with an overall mortality of 15.3%. Mean age was 60.0 ± 13.6 years. There was a male predominance, although female subjects made up a larger proportion of older age groups-female subjects up 18.4% of patients younger than 40 years with ATAAD but 53.6% of patients older than 80 years. In multivariable analysis controlling for sex, race, comorbidities, and malperfusion, age was a significant predictor of mortality. Patients aged 71 to 80 years had a 5.3-fold increased risk of mortality compared with patients ≤40 years old (P < .001), and patients aged >80 years had a 6.8-fold increased risk of mortality (P < .001). Sex was not significantly associated with mortality. Conclusions: Surgical repair of ATAAD continues to carry high risk of morbidity and mortality, with outcomes impacted significantly by patient age, regardless of patient comorbidity burden.
RESUMO
OBJECTIVE: The utilization of extracorporeal membrane oxygenation (ECMO) during cardiopulmonary resuscitation (ECPR) has demonstrated promising evidence for the management of out-of-hospital cardiac arrest (OHCA). We aim to describe contemporary utilization and predictors of survival of patients receiving ECPR for OHCA. METHODS: The National Inpatient Sample (NIS) was queried to identify hospital discharge records of patients aged ≥18 years who underwent ECPR from 2012 to 2017. Patients with an International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis of cardiac arrest, admitted urgently and placed on ECMO on Day 0 of hospitalization, were selected. Patients with a primary diagnosis indicative of veno-venous ECMO were excluded. Predictors of mortality were assessed using multivariable analyses. RESULTS: There were 1675 cases of ECPR, increasing from 185 cases in 2012 to 400 in 2017 (p < .001). Overall mortality was 63.3%, which remained stable over time (p = .441). Common diagnoses included ST-elevation myocardial infarction (39.1%), non-ST-elevation myocardial infarction (9.3%), and pulmonary embolism (13.7%). Percutaneous coronary intervention was performed in 495 patients (29.6%); coronary artery bypass grafting was performed in 125 patients (7.5%). In multivariable analysis, decreased age, female gender, and left ventricular (LV) decompression were associated with reduced mortality. CONCLUSION: Utilization of ECPR is increasing nationally with stable mortality rates. Younger age, female gender, and utilization of LV decompression were associated with increased survival.

BACKGROUND: Cardiac interventions performed urgently are known to be associated with poor outcomes compared with electively performed procedures. Transcatheter edge-to-edge mitral valve repair (TMVr) has developed as a reasonable alternative to mitral valve surgery in certain patient populations. We aimed to leverage a national database to identify predictors of urgent versus elective TMVr, as well as the association between urgency and outcomes. METHODS: The National Inpatient Sample (NIS) was queried to identify patients who underwent TMVr from 2016 to 2017. Hospitalizations were identified within the database as elective versus nonelective. Univariate and multivariable analyses were performed to identify patient characteristics associated with urgent procedures. In-hospital outcomes were assessed. RESULTS: There were 10,195 cases of TMVr in this cohort, 24.2% of which were performed urgently. In multivariable analysis, Hispanic race, Medicaid insurance, and low income were associated with increased likelihood of urgent hospital admission and TMVr. Additionally, small hospital size and Northeast region were associated with increased likelihood of urgent admission and procedure. Urgent TMVr was associated with increased mortality (4.5% vs. 1.6%, p < .001), prolonged length of stay (6.0 vs. 2.0, p < .001), and increased cost ($71,451.90 vs. $44,981.20, p < .001). CONCLUSIONS: Racial and socioeconomic disparities exist in the utilization of TMVr as an urgent versus elective procedure, suggesting differences in access to surveillance and preventive care. Urgent TMVr is associated with increased morbidity and mortality, prolonged length of stay, and increased hospital costs. Priority should be placed on mitigating such disparities to improve outcomes.

BACKGROUND: As the symptoms for both chronic lung disease (CLD) and aortic stenosis (AS) frequently overlap, it may be challenging to determine the degree of symptomatic improvement expected for a patient with CLD after correction of AS. Our aim was to determine if patients with CLD have the same degree of quality-of-life improvement following transcatheter aortic valve replacement (TAVR) as patients without CLD. METHODS: A retrospective review of 238 TAVR patients from January 2017 to November 2018 who underwent preoperative pulmonary function tests and completed 30-day follow-up was performed. Patients were identified as having CLD with FEV1 more than 75% predicted. Postoperative outcomes and changes in Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) were compared between groups. RESULTS: Of the 238 patients identified, 143 (60.0%) had CLD, 50 (35.0%) of whom had an obstructive disease pattern. Patients with CLD were more likely to be male, had higher rates of peripheral artery disease, and had lower baseline ejection fraction. There was no difference in STS Predicted Risk of Mortality, but patients with CLD were more likely to be designated as high-risk by surgeon evaluation. While initial and follow-up KCCQ-12 was lower for patients with CLD, there was no significant difference in degree of improvement (p = .900). When comparing patients with obstructive lung disease (FEV1/FVC < 0.70) to those without CLD, there was also no significant difference in the change of quality of life (p = .720). CONCLUSION: Although patients with concomitant severe AS and CLD have reduced baseline quality of life compared to patients without CLD, they experience a comparable degree of improvement following TAVR.

OBJECTIVE: Patient-prosthesis mismatch (PPM) is associated with poor outcomes after aortic valve replacement. The aim of this study was to assess the accuracy of indexed effective orifice area (EOAi) charts in predicting PPM after transcatheter aortic valve replacement (TAVR). METHODS: A retrospective review of 346 TAVR patients from January 2017 to November 2018 was performed. EOAi was predicted for patients based on published predictive tables using valve type, annulus diameter, and body surface area. Actual EOAi was calculated based on intraoperative transesophageal echocardiogram (TEE) measurements. PPM was defined by EOAi ≤ 0.85 cm2 /m2 . The accuracy of predicted PPM was assessed. Differences in clinical outcomes, including mean gradient, length of stay, mortality, complications, and change in Kansas City cardiomyopathy questionnaire score as an indicator of quality of life, were evaluated based on actual PPM. RESULTS: Of the 346 patients analyzed, 44 (12.7%) of patients had PPM on intraoperative TEE. Of the 182 patients who received Sapien 3 valves, 42 (23.1%) were predicted to have PPM while 25 (13.7%) had actual PPM. Of the 164 patients who received Evolut valves, 3 (1.8%) were predicted to have PPM while 19 (11.6%) had actual PPM. EOAi charts had poor sensitivity (40.0% for Sapien 3; 5.25% for Evolut) and positive predictive value (23.8% for Sapien 3; 33.3% for Evolut) for both valve types. CONCLUSION: Preoperative prediction of PPM in TAVR patients using tables of expected EOA demonstrates significant variation from actual PPM. The utility of EOAi charts to predict PPM in patients undergoing TAVR may be limited.

RESUMO
BACKGROUND: Early mortality has plagued the otherwise good outcomes of heart transplantation in patients with adult congenital heart disease (ACHD), but perioperative care is improving. This study sought to identify risk factors for 1-year mortality currently and examine the results of patients without those risk factors compared with patients who did not have ACHD (nACHD). METHODS: The United Network of Organ Sharing database was searched for all adult (>17 years of age) heart transplant recipients from 2000 to 2018. They were divided into an early era and a late era. A multivariate analysis identified risk factors for 1-year mortality in the late era. Patients without these risk factors were compared with the nACHD group by Kaplan-Meier analysis. RESULTS: A total of 495 patients with ACHD were identified from 2000 to 2008, and 666 were identified from 2009 to 2018. The recent era had better 1-year survival (P <.001) and overall survival (P = .003) than did the era from 2000 to 2008. Patients with ACHD were different from the nACHD population in age (37 years vs 57 years), body mass index greater than 25 kg/m2 (45% vs 66%), incidence of renal dysfunction (23% vs 28%) and liver dysfunction (29% vs 23%), sensitization (38% vs 29%), and ischemic times (3.5 hours vs 3.1 hours). Multivariate analysis identified body mass index greater than 25 kg/m2 (hazard ratio [HR], 1.79), renal dysfunction (HR, 1.85), liver dysfunction (HR, 1.69), and longer ischemic time (HR, 1.46) as risk factors for early mortality. Patients with only 1 of the first 3 categorical risk factors had 1-year survival comparable to that reported in patients with nACHD. CONCLUSIONS: Patients with ACHD had better early and long-term outcomes in the recent era. When only 1 of 3 pretransplant risk factors for early mortality was present, patients had survival equal to that of nACHD patients and perhaps better long-term survival.

BACKGROUND: There are disparate data on the outcomes of nonagenarians undergoing transcatheter aortic valve replacement (TAVR) compared with younger patients. The purpose of this study is to determine whether the Society of Thoracic Surgeons (STS) score can be used to identify the subset of nonagenarians that are at a significantly higher risk for poor postoperative outcomes after TAVR. METHODS: A total of 425 patients above the age of 80 underwent elective TAVR between 12/2013 and 2/2018 and were included in this study. Patients were deemed intermediate or high risk based on an STS predicted the risk of surgical mortality score of 3% to 8% and more than 8%, respectively. Differences in postoperative outcomes and/or 6-month mortality between intermediate and high-risk octogenarians and nonagenarians were compared. RESULTS: Of the 425 patients, 112 (26.4%) patients were nonagenarians, and 313 (73.6%) patients were octogenarians. Fifty-four (48.2%) of the nonagenarians were stratified as high-risk, while 78 (24.9%) of the octogenarians were stratified as high-risk. There were no statistically significant differences in the composite outcomes between intermediate-risk nonagenarians and intermediate-risk octogenarians. In contrast, high-risk nonagenarians were significantly more likely to experience the composite outcome of major perioperative complications and/or 6-month mortality as compared to high-risk octogenarians. CONCLUSION: Intermediate-risk nonagenarians undergoing TAVR have similar postoperative outcomes compared to intermediate-risk octogenarians. However, high-risk nonagenarian patients undergoing TAVR experience significantly poorer outcomes compared to their octogenarian counterparts. Judicious patient selection for TAVR in this subgroup of patients is therefore warranted.

Objectives: Heparin-induced thrombocytopenia (HIT) is an immune-mediated complication that occurs in a small percentage of patients exposed to heparin. Concerns of HIT are particularly high in patients undergoing cardiac procedures requiring cardiopulmonary bypass, as they are exposed to high doses of heparin intraoperatively. Our aim was to identify and assess the hospital courses of patients who were diagnosed with HIT during readmission following cardiac surgery. Methods: A retrospective review of patients who underwent open cardiac surgical procedures from June 2017 through October 2019 was performed. Of these, we identified patients who were newly diagnosed with HIT upon readmission. HIT positivity was defined as a positive anti-PF4 antibody screening test, plus a positive serotonin release assay. Results: Of the 2496 patients identified, 13 patients were HIT positive on index admission and were excluded. Of the remaining 2483 patients, 351 were readmitted within 30 days. Six were newly diagnosed with HIT during readmission, 5 of whom presented with thrombotic complications. One patient was readmitted with thrombocytopenia and was started on argatroban; the remaining 5 did not have a significantly lower platelet count on readmission. Of the 12 patients readmitted for venous thromboembolism, 4 tested positive for HIT. Conclusions: HIT can have a delayed appearance following open heart surgery. Venous thromboembolism appears to be a significant indicator for HIT during readmission, even in the absence of thrombocytopenia. This may support the use of non-heparin anticoagulation for cardiac surgery patients readmitted with thromboembolism until HIT status is determined.
RESUMO
OBJECTIVES: The objective of this study is to determine incidence of acute kidney injury (AKI) associated with transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in patients with preexisting chronic kidney disease. BACKGROUND: The incidence of AKI in patients with preexisting renal insufficiency undergoing TAVR versus SAVR is not well described. METHODS: All patients with preexisting chronic kidney disease who underwent SAVR for aortic stenosis with or without concomitant coronary artery bypass grafting or TAVR from 5/2008 to 6/2017. Patients requiring preoperative hemodialysis were excluded. Chronic kidney disease was defined as an estimated glomerular filtrate rate (eGFR) of < 60 mL/min/1.73 m2. The incidence of postoperative AKI was compared using the RIFLE classification system for acute kidney injury. RESULTS: A total of 406 SAVR patients and 407 TAVR patients were included in this study. TAVR patients were older and had lower preoperative eGFR as compared to SAVR patients. Covariate adjustment using propensity score between the two groups showed that SAVR patients were more likely to have a more severe degree of postoperative AKI as compared to TAVR patients (OR = 4.75; 95% CI: 3.15, 7.17; p <.001). SAVR patients were more likely to require dialysis postoperatively as compared to TAVR patients (OR = 4.55; 95% CI: 1.29, 15.99; p <.018). CONCLUSION: In patients with preexisting chronic kidney disease, TAVR was associated with significantly less AKI as compared to SAVR.

OBJECTIVE: Predictors of operative outcome in patients with severely depressed left ventricular ejection fraction (LVEF) undergoing coronary artery bypass grafting (CABG) remain poorly defined. This study aims to identify preoperative variables that are associated with increased postoperative length of hospital stay or operative mortality in this patient population. DESIGN: Retrospective study. SETTING: Single tertiary care university hospital. PARTICIPANTS: Patients undergoing isolated CABG between January 2012 and March 2017 with an LVEF ≤ 25%. INTERVENTIONS: Isolated CABG. MEASUREMENTS AND MAIN RESULTS: Primary endpoint was a composite of prolonged length of stay, defined as postoperative length of stay >7 days or operative mortality. Of the 201 patients, 99 (49.3%) met the primary endpoint. Patient comorbidities, clinical presentation, presence of Q-waves on electrocardiogram, and echocardiographic parameters including ventricular dimensions and right heart dysfunction were not associated with the primary endpoint. On multivariable analysis, patients who were not on preoperative beta-blockers, patients with preoperative albumin of <3.5 g/dL, and higher Society of Thoracic Surgeons Predicted Risk of Mortality score were associated with increased prolonged length of stay or death. CONCLUSIONS: More than half of patients with severely depressed LVEF undergoing isolated CABG are able to be discharged within 7 days postoperatively. The absence of preoperative beta-blockers, low preoperative albumin levels, and higher Society of Thoracic Surgeons Predicted Risk of Mortality score are associated with more complicated or slower postoperative recovery after CABG in this patient population.
