ABSTRACT

BACKGROUND: Hospital readmissions following left ventricular assist device (LVAD) remain a frequent comorbidity, associated with decreased quality of life and increased resources utilization. This study sought to determine causes, predictors, and impact on survival of hospitalizations during HeartMate 3 (HM3) support. METHODS: All patients implanted with HM3 between November 2014 to December 2019 at Columbia University Irving Medical Center were consecutively enrolled in the study. Demographics and clinical characteristics from the index admission and the first outpatient visit were collected and used to estimate 1-year and 900-day readmission-free survival and overall survival. Multivariable analysis was performed for subsequent readmissions. RESULTS: Of 182 patients who received a HM3 LVAD, 167 (92%) were discharged after index admission and experienced 407 unplanned readmissions over the median follow up of 727 (interquartile range (IQR): 410.5, 1124.5) days. One-year and 900-day mean cumulative number of all-cause unplanned readmissions was 0.43 (95%CI, 0.36, 0.51) and 1.13 (95%CI, 0.99, 1.29). The most frequent causes of rehospitalizations included major infections (29.3%), bleeding (13.2%), device-related (12.5%), volume overload (7.1%), and other (28%). One-year and 900-day survival free from all-cause readmission was 38% (95%CI, 31-46%) and 16.6% (95%CI, 10.3-24.4%). One-year and 900-day freedom from 2, 3, and ≥4 readmissions were 60.7%, 74%, 74.5% and 26.2%, 33.3%, 41.3%. One-year and 900-day survival were unaffected by the number of readmissions and remained >90%. Male sex, ischemic etiology, diabetes, lower serum creatinine, longer duration of index hospitalization, and a history of readmission between discharge and the first outpatient visit were associated with subsequent readmissions. CONCLUSIONS: Unplanned hospital readmissions after HM3 are common, with infections and bleeding accounting for the majority of readmissions. Irrespective of the number of readmissions, one-year survival remained unaffected.

ABSTRACT

Objective: This study assessed characteristics and outcomes of younger (18-65) versus older (>65) recipients of simultaneous heart-kidney (SHK) transplantation with varying functional dependence. Methods: This study retrospectively analyzed 1398 patients from the United Network for Organ Sharing database who received SHK between 2010 and 2021. Patients who were <18 year old, underwent transplant of additional organs simultaneously, or had previous heart transplant were excluded. The primary end point was all-cause mortality, and secondary end points included adverse events and cause of death. Outcomes were also evaluated by propensity score-matched comparison. Results: The number of annual SHK transplantation in the United States has significantly increased among both age groups over the past 2 decades (P < .0001). After propensity score matching of recipients aged 18 to 65 years (n = 1162) versus age >65 years (n = 236), baseline characteristics were similar and well-balanced between the 2 cohorts. Between matched cohorts, older recipients did not have increased posttransplant mortality compared with younger recipients (90-day survival, P = .85; 7-year survival, P = .61). Multivariable Cox regression analysis found that age (hazard ratio [HR], 1.039 [0.975-1.106], P = .2415) and pretransplant functional status with interaction term for age (some assistance, HR, 0.965 [0.902-1.033], P = .3079; total assistance, HR, 0.976 [0.914-1.041], P = .4610) were not significant risk factors for 7-year post-SHK transplantation mortality. Conclusions: Older and more functionally dependent recipients in this study did not have increased post-SHK transplantation mortality. These findings have important implications for organ allocation among elderly patients, as they support the need for thorough assessment of SHK candidates in terms of comorbidities, rather than exclusion solely based on age and functional dependence.

ABSTRACT

While disparities in access to reconstruction persist, a comprehensive analysis comparing state-based outcomes and national patterns in breast reconstruction as a result of Medicaid expansion has never been examined. In this study, we investigated how breast reconstruction rates changed as a result of Medicaid expansion and compared these state-based findings to national counterparts. Patient data from the Healthcare Cost and Utilization Project among states that chose to expand Medicaid were compared with those from states that did not expand. The difference-in-differences estimate of expansion to nonexpansion states was 7.05 (p = 0.10) for implant-based reconstruction, -11.56 (p = 0.01) for autologous reconstruction, and -7.08 (p = 0.18) for overall reconstruction. Comparing rates of nonexpansion states to national trends yielded estimates of -0.06 (p = 0.04), 0.06 (p = 0.01), and 0.004 (p = 0.90) for implant-based, autologous, and overall breast reconstruction, respectively. Similarly, comparing rates of expansion states to national trends yielded estimates of 0.02 (p = 0.38), -0.05 (p = 0.03), and -0.02 (p = 0.44) for implant-based, autologous, and overall breast reconstruction, respectively. In this study on national health policy, Medicaid expansion was associated with a significant increase in autologous rates while state-specific trends alone did not appear to predict the national outcomes of sweeping legislative changes that were differentially applied among states.

ABSTRACT

BACKGROUND: The benefits of mitral valve repair vs replacement are well documented. However, survival benefits in the elderly population are more controversial. In this novel lifetime analysis, we hypothesize that survival benefits for valve repair vs replacement in the elderly are sustained throughout the patient's lifetime. METHODS: From January 1985 through December 2005, 663 patients, aged ≥65 years with myxomatous degenerative mitral valve disease underwent primary isolated mitral valve repair (n = 434) or replacement (n = 229). Propensity score matching was used to balance variables potentially related to outcome. RESULTS: Follow-up was complete in 99.1% of mitral repair and 99.6% of mitral replacement patients. In matched patients, perioperative mortality was 3.9% (9 of 229) for repair and 10.9% (25 of 229) for replacement (P = .004). Survival estimates (95% confidence limits) from 29-year follow-up for matched patients were 54.6% (48.0%, 61.1%) and 11.0% (6.8%, 15.2%) at 10 years and 20 years for repair patients, and 34.2% (27.7%, 40.7%) and 3.7% (1%, 6.4%) for replacement patients, respectively. Median survival (95% confidence limits) was 11.3 years (9.6, 12.2 years) for repair patients compared with 6.9 years (6.3, 8.0 years) for replacement patients (P < .001). CONCLUSIONS: This study demonstrates that although the elderly population is prone to multiple comorbidities, survival benefits of isolated mitral valve repair vs replacement are sustained throughout the patient's lifetime.

ABSTRACT

OBJECTIVES: To determine the role of adding open distal anastomosis to proximal aortic aneurysm repairs in bicuspid aortic valve (BAV) patients. METHODS: Retrospective review was performed of 1132 patients at our Aortic Center between 2005 and 2019. Inclusion criteria were all patients diagnosed with a BAV who underwent proximal aortic aneurysm repair with open or clamped distal anastomosis. Exclusion criteria were patients without a BAV, age < 18 years, aortic arch diameter ≥ 4.5 cm, type A aortic dissection, previous ascending aortic replacement, ruptured aneurysm, and endocarditis. Propensity score matching in a 2:1 ratio (220 clamped: 121 open repairs) on 18 variables was performed. RESULTS: Median follow-up time was 45.6 months (range 7.2-143.4 months). In the matched groups, no significant differences were observed between the respective open and clamped distal anastomosis groups for Kaplan Meier 10-year survival (86.9% vs. 92.9%; p = 0.05) and landmark survival analysis after 1 year (90.6%; vs. 93.3%; p = 0.39). Overall incidence of aortic arch-related reintervention was low (n = 3 total events). In-hospital complications were not significantly different in the open with respect to the clamped repair group, including in-hospital mortality (2.5% vs. 0.5%; p = 0.13) and stroke (0% vs. 0.9%; p = 0.54). In multivariable analysis, open distal anastomosis repair was not associated with long-term mortality (Hazard Ratio (HR) 1.98; p = 0.06). CONCLUSION: We found no significant inter-group differences in survival, reintervention, or in-hospital complication rates, with low rates of mortality, and aortic arch-related reintervention, suggesting adding open distal anastomosis may not provide benefit in BAV patients undergoing proximal aortic aneurysm repairs.

ABSTRACT

BACKGROUND: Little is known regarding the profile of patients with multiorgan failure listed for simultaneous cardiac transplantation and secondary organ. In addition, few studies have reported how these patients are bridged with mechanical circulatory support (MCS). In this study, we examined national data of patients listed for multiorgan transplantation and their outcomes after bridging with or without MCS. METHODS: United Network for Organ Sharing data were reviewed for adult multiorgan transplantations from 1986 to 2019. Post-transplant patients and total waitlist listings were examined and stratified according to MCS status. Survival was assessed via Cox regression in the post-transplant cohort and Fine-Gray competing risk regression with transplantation as a competing risk in the waitlist cohort. RESULTS: There were 4534 waitlist patients for multiorgan transplant during the study period, of whom 2117 received multiorgan transplants. There was no significant difference in post-transplant survival between the MCS types and those without MCS in the whole cohort and heart-kidney subgroup. Fine-Gray competing risk regression showed that patients bridged with extracorporeal membrane oxygenation had significantly greater waitlist mortality compared with those without MCS when controlling for preoperative characteristics (subdistribution hazard ratio, 2.27; 95% confidence interval, 1.48-3.47; P < .001), whereas those bridged with a ventricular assist device had a decreased incidence of death compared with those without MCS (subdistribution hazard ratio, 0.78; 95% confidence interval, 0.63-0.96; P = .017). CONCLUSIONS: MCS, as currently applied, does not appear to compromise the survival of multiorgan heart transplant patients. Waitlist data show that extracorporeal membrane oxygenation patients have profoundly worse survival irrespective of preoperative factors including organ type listed. Survival on the waitlist for multiorgan transplant has improved across device eras.

ABSTRACT

BACKGROUND: Continuous-flow left ventricular assist devices commonly lead to aortic regurgitation, which results in decreased pump efficiency and worsening heart failure. We hypothesized that non-physiological wall shear stress and oscillatory shear index alter the abundance of structural proteins in aortic valves of left ventricular assist device (LVAD) patients. METHODS: Doppler images of aortic valves of patients undergoing heart transplants were obtained. Eight patients had been supported with LVADs, whereas 10 were not. Aortic valve tissue was collected and protein levels were analyzed using mass spectrometry. Echocardiographic images were analyzed and wall shear stress and oscillatory shear index were calculated. The relationship between normalized levels of individual proteins and in vivo echocardiographic measurements was evaluated. RESULTS: Of the 57 proteins of interest, there was a strong negative correlation between levels of 15 proteins and the wall shear stress (R < -0.500, p ≤ 0.05), and a moderate negative correlation between 16 proteins and wall shear stress (R -0.500 to -0.300, p ≤ 0.05). Gene ontology analysis demonstrated clusters of proteins involved in cellular structure. Proteins negatively correlated with WSS included those with cytoskeletal, actin/myosin, cell-cell junction and extracellular functions. C: In aortic valve tissue, 31 proteins were identified involved in cellular structure and extracellular junctions with a negative correlation between their levels and wall shear stress. These findings suggest an association between the forces acting on the aortic valve (AV) and leaflet protein abundance, and may form a mechanical basis for the increased risk of aortic leaflet degeneration in LVAD patients.

ABSTRACT

BACKGROUND: The elderly population is growing at an unprecedented rate. Aortic valve disease increases with age. Bioprostheses are the valves of choice for older patients; however, the optimal tissue valve remains undetermined. The purpose of this investigation was to perform a life-of-patient survival comparison of the prototypical porcine and pericardial prostheses in elderly patients. METHODS: The study population (N = 1480) consisted of patients 65 years of age and older who underwent isolated aortic valve replacement from 1990 through 2005 with a Carpentier-Edwards Porcine (n = 650) or Pericardial (n = 830) bioprosthesis. Propensity score-matched groups were created. RESULTS: Valve selection was not associated with operative mortality. Survival estimates at 10 years were better for Pericardial (41.8%; 95% CI: 37.9 to 45.7) than Porcine (32.6%; 95% CI: 28.8 to 36.3); and 5.2% (95% CI: 3.2 to 7.1) versus 2.0%; (95% CI: 0.8 to 3.2) at 20 years (p < 0.001). E-value analysis found minimal influence of unknown study confounders. Factors associated with long-term mortality were porcine valve (p < 0.001), age (p < 0.001), diabetes mellitus (p < 0.001), preop renal insufficiency (p < 0.001), peripheral artery disease (p = 0.011), congestive heart failure (p = 0.003), New York Heart Association Class III or IV (p = 0.004), surgical history-reoperation (p = 0.012), transient ischemic attack (p = 0.009), prolonged ventilation (p = 0.010), postop renal insufficiency (p < 0.001), and atrial fibrillation (p = 0.009). The indexed Effective Orifice Area (EOAi) was assessed and did not influence observed long-term survival differences. CONCLUSIONS: This unusual lifetime study provided substantial evidence for the superiority of the pericardial over the porcine bioprosthesis in the aortic position in elderly patients. It demonstrated enhanced long-term survival benefits for elderly patients without any increase in perioperative mortality. It is intended to inform future investigation into aortic valve design.

ABSTRACT

OBJECTIVE: Implantation of a transcatheter valve-in-mitral annular calcification (ViMAC) has emerged as an alternative to traditional surgical mitral valve (MV) replacement. Previous studies evaluating ViMAC aggregated transseptal, transapical, and transatrial forms of the procedure, leaving uncertainty about each technique's advantages and disadvantages. Thus, we sought to evaluate clinical outcomes specifically for transatrial ViMAC from the largest multicenter registry to-date. METHODS: Patients with symptomatic MV dysfunction and severe MAC who underwent ViMAC were enrolled from 12 centers across the United States and Europe. Clinical characteristics, procedural details, and clinical outcomes were abstracted from the electronic record. The primary end point was all-cause mortality. RESULTS: We analyzed 126 patients who underwent ViMAC (median age 76 years [interquartile range {IQR}, 70-82 years], 28.6% female, median Society of Thoracic Surgeons score 6.8% [IQR, 4.0-11.4], and median follow-up 89 days [IQR, 16-383.5]). Sixty-one (48.4%) had isolated mitral stenosis, 25 (19.8%) had isolated mitral regurgitation (MR), and 40 (31.7%) had mixed MV disease. Technical success was achieved in 119 (94.4%) patients. Thirty (23.8%) patients underwent concurrent septal myectomy, and 8 (6.3%) patients experienced left ventricular outflow tract obstruction (7/8 did not undergo myectomy). Five (4.2%) patients of 118 with postprocedure echocardiograms had greater than mild paravalvular leak. Thirty-day and 1-year all-cause mortality occurred in 16 and 33 patients, respectively. In multivariable models, moderate or greater MR at baseline was associated with increased risk of 1-year mortality (hazard ratio, 2.31; 95% confidence interval, 1.07-4.99, P = .03). CONCLUSIONS: Transatrial ViMAC is safe and feasible in this selected, male-predominant cohort. Patients with significant MR may derive less benefit from ViMAC than patients with mitral stenosis only.

ABSTRACT

The 2021 Coronary Artery Disease revascularization guidelines of the American College of Cardiology (ACC), the American Heart Association (AHA), and the Society for Cardiovascular Angiography and Interventions (SCAI) provide recommendations for managing nonculprit arteries in ST-segment elevation myocardial infarction (STEMI). Although staged revascularization is preferred, at times same-setting intervention, coronary artery bypass surgery, or medical therapy may be preferable. These cases exemplify clinical scenarios for treating nonculprit arteries in STEMI. (Level of Difficulty: Intermediate.).

ABSTRACT

BACKGROUND: As cardiac re-transplantation is associated with inferior outcomes compared with primary transplantation, allocating scarce resources to appropriate re-transplant candidates is important. The aim of this study is to elucidate the factors associated with 1-year mortality in cardiac re-transplantation using the random forests algorithm for survival analysis. METHODS: We retrospectively reviewed the United Network for Organ Sharing registry and identified all adult (> 17 years old) recipients who underwent cardiac re-transplantation between January 2000 and March 2020. The random forest algorithm on Cox modeling was used to calculate the variable importance (VIMP) of independent variables for contributing to 1-year mortality. RESULTS: A total of 1294 patients underwent cardiac re-transplantation. Of these, 137 patients were re-transplanted within 1 year of their first transplant, while 1157 patients were re-transplanted more than 1 year after their first transplant. One-year mortality was significantly higher for patients receiving early transplantation compared with those receiving late transplantation (Early 40.6% vs. Late 13.6%, log-rank P < .001). Machine learning analysis showed that total bilirubin (> 2 mg/dl) (VIMP, 2.99%) was an independent predictor of 1-year mortality after early re-transplant. High BMI (> 30.0 kg/m2 ) (VIMP, 1.43%) and ventilator dependence (VIMP, 1.47%) were independent predictors of 1-year mortality for the late re-transplantation group. CONCLUSION: Machine learning showed that optimal 1-year survival following cardiac re-transplantation was significantly related to liver function in early re-transplantation, and to obesity and preoperative ventilator dependence in late re-transplantation.

ABSTRACT

INTRODUCTION: Venous thromboembolism (VTE), such as deep vein thrombosis (DVT) and pulmonary embolism (PE), is an important and serious postoperative complication after heart transplantation. We sought to characterize in-hospital VTE after heart transplantation and its association with clinical outcomes. METHOD: Adult (≧18 years) patients undergoing heart transplantation from 2015 to 2019 at our center were retrospectively reviewed. Post-transplant VTE was defined as newly diagnosed venous system thrombus by imaging studies. RESULTS: There were 254 patients. The cohort's median age was 55 years. A total of 61 patients were diagnosed with VTE, including one with right atrial thrombus, 54 with upper extremity DVT in which one patient subsequently developed PE, four with lower extremity DVT, and two with upper and lower extremity DVT. The cumulative incidence of VTE was 42% at 60-days of post heart transplant. Patients with VTE had longer hospital stay (P < .001), higher in-hospital mortality (P = .010), and worse 5-year survival (P = .009). On the multivariable Cox analysis, history of DVT/PE and intubation for more than 3 days were associated with an increased risk of in hospital VTE. CONCLUSION: The incidence of VTE in heart transplant recipients is high. Post-transplant surveillance, and appropriate preventive measures and treatment strategies after diagnosis are warranted.

ABSTRACT

BACKGROUND: This large cohort, single-center study compared the 10-year survival and freedom from aortic valve reintervention between valve-sparing root replacement (VSRR) and bioprosthetic Bentall (bio-Bentall). METHODS: All patients undergoing elective VSRR or bio-Bentall for aortic root aneurysm between March 2005 through October 2019 were retrospectively reviewed (N = 796; n = 360 for VSRR). Inverse probability of treatment weighting (IPTW) balanced clinical variables between groups. Mean follow-up was 58.0 ± 45.4 months (range, 0-167 months). RESULTS: After IPTW adjustment, 10-year survival did not differ between VSRR (87.0%) and bio-Bentall (92.7%, P = 0.780). Cumulative incidence of aortic valve reintervention was 5.9% for VSRR (95% confidence interval [CI], 2.9%-10.4%) and 10.6% for bio-Bentall (95% CI, 6.2%-16.4%; P = .798). A Fine and Gray competing risk regression model identified age at operation (subdistribution hazard ratio [sHR], 0.97; 95% CI, 0.95-0.99; P = .015), body surface area (sHR, 6.21; 95% CI, 1.97-19.59; P = .002), and bicuspid aortic valve (sHR, 2.15; 95% CI, 1.04-4.44; P = .038) as independently associated with aortic valve reintervention. For patients aged 50 years or younger, the cumulative incidence of aortic valve reintervention was 16.2% for VSRR (95% CI, 7.0%-28.8%) and 17.8% for bio-Bentall (95% CI, 6.9%-32.8%; P = .363). CONCLUSIONS: VSRR and bio-Bentall show similar excellent survival and freedom from aortic reintervention rates up to 10 years; however, a durable valve solution for young patients with bicuspid aortic valve remains a challenge.

ABSTRACT

BACKGROUND: Composite performance measures for the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database participants (typically hospital departments or practice groups) are currently available only for individual procedures. To assess overall participant performance, STS has developed a composite metric encompassing the most common adult cardiac procedures. METHODS: Analyses included 1-year (July 1, 2018 to June 30, 2019) and 3-year (July 1, 2016 to June 30, 2019) time windows. Operations included isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve repair (MVr) or replacement (MVR), AVR + CABG, MVr or MVR + CABG, AVR + MVr or MVR, and AVR + (MVr or MVR) + CABG. The composite was estimated using Bayesian hierarchical models with risk-adjusted mortality and morbidity end points. Star ratings were based upon whether the 95% credible interval of a participant's score was entirely lower than (1 star), overlapping (2 star), or higher than (3 star) the STS average composite score. RESULTS: The North American procedural mix in the 3-year study cohort was as follows: 448 569 CABG, 72 067 AVR, 35 708 MVr, 29 953 MVR, 45 254 AVR + CABG, 12 247 MVr + CABG, 10 118 MVR + CABG, 3743 AVR + MVr, 6846 AVR + MVR, and 3765 AVR + (MVr or MVR) + CABG. Mortality and morbidity weightings were similar for 1- and 3-year analyses (76% and 24% [3-year]), as were composite score distributions (median, 94.7%; interquartile range, 93.6% to 95.6% [3-year]). The 3-year time frame was selected for operational use because of higher model reliability (0.81 [0.78-0.83]) and better outlier discrimination (26%, 3 star; 16%, 1 star). Risk-adjusted outcomes for 1-, 2-, and 3-star programs were 4.3%, 3.0%, and 1.8% mortality and 18.4%, 13.4%, and 9.7% morbidity, respectively. CONCLUSIONS: The STS participant-level, multiprocedural composite measure provides comprehensive, highly reliable, overall quality assessment of adult cardiac surgery practices.

ABSTRACT

BACKGROUND: Anorectal cases may be a common gateway to the opioid epidemic. Opioid reduction is inherent in enhanced recovery after surgery (ERAS) protocols, but little work has evaluated ERAS in these cases. OBJECTIVE: To determine if ERAS could reduce postoperative opioid utilization in ambulatory anorectal surgery without sacrificing patient pain or satisfaction. METHODS: A randomized controlled trial assigned ambulatory anorectal patients to ERAS (experimental) or routine care (surgeon's choice) for pain management (control) over 30-days postoperatively. Primary outcome was overall days of opioid use. Secondary outcomes included pain and satisfaction scores over multiple time points and new persistent opioid use. The Visual Analog Scale, Functional Pain Scale, and EQ-5D-3L measured patient-reported pain and satisfaction. Univariate analysis compared outcomes overall and at individual time points. Two-way mixed ANOVA evaluated pain and satisfaction measures between groups and over time. RESULTS: Thirty-two patients were randomized into each arm (64 total). The control group consumed significantly more opioids after discharge (median 121.3MME vs 23.5MME, P < 0.001). Significantly more control patients requested additional narcotics (P  =  0.004), made unplanned calls (P = 0.009), and had unplanned clinic visits (P = 0.003). The control group had significantly more days on opioids (mean 14.4 vs 2.2, P < 0.001). Three control patients (9.4%) versus no experimental patients had new persistent opioid use. The mean global health, EQ5D-3L, Visual Analog Scale, and Functional Pain scores were comparable between groups over time. CONCLUSIONS: An ERAS protocol in ambulatory anorectal surgery is feasible, and resulted in reduced opioid use, and healthcare utilization, with no difference in pain or patient satisfaction. This challenges the paradigm that extended opioids are needed for effective postoperative pain management.

ABSTRACT

BACKGROUND: This study aims to comprehensively characterize details of aortic and aortic valve reinterventions after aortic root replacement (ARR). METHODS: Between 2005 and 2019, 882 patients underwent ARR. Indications were aneurysm in 666, aortic valve related in 116, aortic dissection in 64, and infective endocarditis (IE) in 36. Valve-sparing root replacement was performed in 290 patients, whereas a Bio-Bentall procedure was done in 528. Among them, 52 patients (5.9%) required reintervention. The incidence, cause, and time to reintervention and the outcomes after reintervention were investigated. A cause-specific Cox hazard model was performed to identify predictors for reintervention after ARR. RESULTS: The 10-year cumulative incidence of aortic and aortic valve reintervention after ARR was 10.3% (95% confidence interval, 7.3%-14.0%). Age per year decrease was the only independent predictor for reintervention (subdistribution hazard ratio, 0.97; 95% confidence interval, 0.95-0.99). The causes for 52 reinterventions were aortic valve causes in 29 patients (55.8%), including aortic stenosis/insufficiency, and prosthetic valve dysfunction; IE in 15 (28.9%); aortic-related causes in 7 (13.5%), including pseudoaneurysm, development of aneurysm, and residual dissection; and coronary button pseudoaneurysm in 1 (1.9%). Median time to reintervention was 11.0 months (interquartile range, 2.0-20.5) for IE, 24.0 months (interquartile range, 3.7-46.1) for aortic-related causes, and 77.0 months (interquartile range, 28.4-97.6) for aortic valve-related causes (P = .005). Overall in-hospital mortality after the reinterventions was 7.7% (4/52) with 20.0% for IE (3/15). CONCLUSIONS: Reintervention for IE occurred relatively early after ARR, whereas aortic valve- and aortic-related reinterventions gradually increased over time. In-hospital mortality after the reintervention was low, with the exception of IE.

ABSTRACT

BACKGROUND: The Society of Thoracic Surgeons (STS) Quality Measurement Task Force has developed risk models and composite performance measures for isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve replacement or repair (MVRR), AVR+CABG, and MVRR+CABG. To further enhance its portfolio of risk-adjusted performance metrics, STS has developed new risk models for multiple valve operations ± CABG procedures. METHODS: Using July 2011 to June 2019 STS Adult Cardiac Surgery Database data, risk models for AVR+MVRR (n = 31,968) and AVR+MVRR+CABG (n = 12,650) were developed with the following endpoints: Operative Mortality, major morbidity (any 1 or more of the following: cardiac reoperation, deep sternal wound infection/mediastinitis, stroke, prolonged ventilation, and renal failure), and combined mortality and/or major morbidity. Data were divided into development (July 2011 to June 2017; n = 35,109) and validation (July 2017 to June 2019; n = 9509) samples. Predictors were selected by assessing model performance and clinical face validity of full and progressively more parsimonious models. Performance of the resulting models was evaluated by assessing discrimination and calibration. RESULTS: C-statistics for the overall population of multiple valve ± CABG procedures were 0.7086, 0.6734, and 0.6840 for mortality, morbidity, and combined mortality and/or morbidity in the development sample, and 0.6953, 0.6561, and 0.6634 for the same outcomes, respectively, in the validation sample. CONCLUSIONS: New STS Adult Cardiac Surgery Database risk models have been developed for multiple valve ± CABG operations, and these models will be used in subsequent STS performance metrics.

ABSTRACT

Stroke has potentially devastating consequences for patients receiving veno-arterial extracorporeal membrane support (VA-ECMO). Arterial cannulation sites for VA-ECMO include the ascending aorta, axillary artery, and femoral artery. However, the influence of cannulation site on stroke risk has not been well described. The purpose of this study was to investigate the association between occurrence and patterns of stroke with ECMO arterial cannulation sites. We retrospectively reviewed 414 consecutive patients who received VA-ECMO support for cardiogenic shock between March 2007 and May 2018. Patients were categorized by cannulation strategy. The rates, subtype and location of strokes as assessed by neuroimaging during and after VA-ECMO support were analyzed. Median age was 61 years (IQR 50-69); 67% were men. 77 patients were cannulated via the ascending aorta (17%), 31 via the axillary artery (7%), and 306 (69%) via the femoral artery. In total, 26 patients (6.3%) developed 30 stroke lesions at a median of 6.0 (IQR 3.1-8.7) days after ECMO cannulation. Ischemic stroke was the most common subtype (64%), followed by hemorrhagic transformation (20%) and hemorrhagic stroke (16%). Location by CT was right hemispheric in 38%, left hemispheric in 24%, bilateral in 21%, and vertebrobasilar in 17%. The incidence of stroke was similar across cannulation strategies: aorta (n = 5, 6.5%), axillary artery (n = 2, 6.5%), and femoral artery (n = 19, 6.2%), (p = 0.99). Incidence of stroke does not appear to differ among patients cannulated via the ascending aorta, axillary artery, or femoral artery. Ischemic stroke was the most common subtype of stroke.
