RESUMO
Artificial Intelligence (AI) has greatly affected our everyday lives and holds great promise to change the landscape of medicine. AI is particularly positioned to improve care for the increasingly complex patients undergoing cardiac surgery utilizing immense amount of data generated in the course of their care. When deployed, AI can be used to analyze this information at the patient's bedside more expediently and accurately, all while providing new insights. This review summarizes the current applications of AI in cardiac surgery, from the vantage point of a patient's journey. Applications of AI include pre-operative risk assessment, intraoperative planning, post-operative patient care and out-patient telemonitoring, encompassing the spectrum of cardiac surgical care. Offloading of administrative processes and enhanced experience with information gathering also represent a unique and underrepresented avenue for future utilization of AI. As clinicians, understanding the nomenclature and applications of AI is important to contextualize problems, to ensure problem-driven solutions and for clinical benefit. Precision medicine, and thus clinically relevant AI, remains dependent on data curation and warehousing to gather insights from large multicenter repositories while treating privacy with the utmost importance. AI tasks should not be siloed but rather holistically integrated into clinical workflow to retain context and relevance. As cardiac surgeons, AI allows us to look forward to a bright future of more efficient utilization of our clinical expertise toward high-level decision making and technical prowess.
RESUMO
OBJECTIVES: The designation of pediatric hospital medicine (PHM) as a board-certified (BC) subspecialty has led to uncertainty about the importance of PHM board certification in hiring pediatric hospitalists and ambiguity in counseling trainees interested in PHM careers about the decision to pursue fellowship. We sought to determine the importance of PHM board eligibility or certification in hiring practices. METHODS: We conducted an online, cross-sectional, survey-based study of individuals who self-identified as PHM division leadership utilizing the PHM Division Director Listserv and participant recruitment at a national meeting. RESULTS: A total of 86 responses were received. A total of 64% (30/47) of university-setting hospitals, 77% (17/28) of community hospitals, and 100% (11/11) of combined settings reported that they will hire applicants who are not board-eligible (BE) or BC (P = .83). Of the hospitals who will be hiring non-BE hospitalists, 50% of university settings, 77% of community settings, and 55% of combined settings plan to give equal consideration to both BE and non-BE applicants (P = .21). A total of 57% (21/37) of programs with a PHM fellowship felt that fellowship training was an important or very important consideration in hiring, compared with 27% (13/49) of programs without a PHM fellowship (P = .04). CONCLUSIONS: Programs with a PHM fellowship were significantly more likely to believe that fellowship training is an important consideration in hiring hospitalists. PHM board certification and fellowship training are perceived as more important by university-based programs, although all settings will consider hiring applicants who are not BC or BE.

OBJECTIVE: Aortic root replacement requires construction of a composite valve-graft and reimplantation of coronary arteries. This study assessed the feasibility of valve-in-valve transcatheter aortic valve implantation after aortic root replacement. METHODS: A retrospective review was conducted on 74 consecutive patients who received a composite valve-graft at a single institution from 2019 to 2021. Forty patients had bioprosthetic valves with adequate postoperative gated computed tomographic angiography scans. Computational simulations of balloon and self-expanding transcatheter valve deployments were performed. The modeled coronary distances were compared with traditional, manually measured valve-to-coronary distances. RESULTS: There was a statistically significant difference in the modeled versus manual measurements of valve to coronary distances for all patients regardless of valve type or coronary artery analyzed (P < .05). Most patients are low risk for coronary obstruction per 3-dimensional modeling, including those with a valve-to-coronary distance <4 mm. Only 1 patient (2.5%) was at risk for coronary obstruction for the left coronary artery using a balloon valve. No other valve combination was considered high risk of coronary obstruction. Five patients (12.5%) were at risk for possible valve stent deformation at the outflow, due to angulation at the graft anastomosis. CONCLUSIONS: Following aortic root replacement, all patients were candidates for valve-in-valve procedure using 1 or both types of transcatheter heart valves. Self-expanding valves may be at higher risk for stent frame deformation at graft anastomotic lines and balloon-expandable valves may be at higher risk of coronary obstruction.
RESUMO
Background: The desire of patients to avoid anticoagulation, together with the potential of valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR), have resulted in the increasing use of bioprosthetic valves for aortic valve replacement (AVR). While patient-prosthesis mismatch (PPM) is known to be an adverse risk after AVR, few studies have addressed the effect of PPM on valve durability. This study evaluates the role of valve size and hemodynamics on long term durability after AVR with a Magna bioprosthesis. Methods: We performed a retrospective, single-center evaluation of patients who underwent a surgical AVR procedure between June 2004 through December 2022 using the Magna bioprosthesis. Perioperative information and long-term follow-up data were sourced from the institution's Society for Thoracic Surgeons Adult Cardiac Surgery Registry and outcomes database. Cumulative incidence of freedom from reintervention were estimated accounting for competing events. Group comparisons used Gray's test. Results: Among 2,100 patients, the mean patient age was 69 years (range, 22-95 years), of whom 98% had native aortic valve disease, 32.5% had concomitant coronary bypass grafting, and 19% had mitral valve surgery. Median follow-up was 5.8 (1.9-9.4) years, during which 116 reinterventions were performed, including 74 explants and 42 VIV procedures. Nine hundred and twenty-eight patients died prior to reintervention. Incidence of all cause reintervention was 1.2%, 4.5%, and 11.7% at 5, 10, and 15 years, respectively. Smaller valve size was associated with worse survival (P<0.001), but not with reintervention. Higher mean gradient at implant was associated with increased late reintervention [sub-distribution hazard ratio: 1.016; 95% confidence interval (CI): 1.005 to 1.028; P=0.0047, n=1,661]. Conclusions: While reintervention rates are low for the Magna prosthesis at 15 years, the analysis is confounded by the competing risk of death. PPM, as reflected physiologically by elevated post-operative valve gradients, portends an increased risk of intervention. Further study is necessary to elucidate the mechanism of early stenosis in patients who progress to reintervention.
RESUMO
BACKGROUND: The benefit of adjuvant therapy (AT) remains unclear in pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant therapy (NAT) and surgical resection. METHODS: The 2019 National Cancer Database was queried for patients with non-metastatic PDAC who received NAT followed by pancreaticoduodenectomy. Only patients with data regarding receipt of AT were included. Patients were classified if they had nodal down-staging specifically, or any downstaging (Tumor, Nodal, or overall). Propensity score matching (PSM) adjusted for pretreatment covariate imbalance between groups. The weighted Kaplan-Meier method and log-rank test were used to estimate the cumulative survival. RESULTS: After exclusion criteria and PSM, a total of 2784 patients remained; 1689 (60.7%) received AT and 1095 (39.3%) did not receive AT. Among all, those with additional AT had a significantly improved overall survival (OS) (p < 0.001). Upon evaluation of patients without downstaging after NAT, those who received AT had improved OS (no nodal downstaging or any downstaging; p = 0.002; p = 0.001). When evaluating patients with downstaging after NAT, those receiving AT did not have improved OS (nodal downstaging or any downstaging: p = 0.352; p = 0.99). CONCLUSION: Response to NAT appears to correlate with the benefit of AT following pancreaticoduodenectomy; patients who have a favorable response to NAT may not benefit from AT.

BACKGROUND: When unanticipated and/or poor patient outcomes occur, clinicians frequently experience guilt, anger, psychological distress, and fear, which can be intensified by traditional morbidity and mortality conferences. METHODS: The Pediatric Event Review and Learning (PEaRL) curriculum was developed to discuss unanticipated and/or poor patient outcomes and foster support while highlighting foundational safety concepts. Pre- and post-implementation evaluations of quarterly cased-based sessions were completed. RESULTS: All respondents endorsed that unanticipated and/or poor patient outcomes affected their mood, well-being, and functioning. Post-implementation of the PEaRL curriculum, significantly more respondents endorsed existence of a safe environment and structured format to discuss these outcomes, as well as feeling more supported. DISCUSSION: The PEaRL curriculum provides a valuable opportunity for trainees and experienced clinicians alike to explore and discuss unanticipated and/or poor patient outcomes while addressing key patient safety principles.

The number of individuals referred for coronary artery bypass grafting (CABG) with preoperative atrial fibrillation (AF) is reported to be 8% to 20%. Atrial fibrillation is a known marker of high-risk patients as it was repeatedly found to negatively influence survival. Therefore, when performing surgical revascularization, consideration should be given to the concomitant treatment of the arrhythmia, the clinical consequences of the arrhythmia itself, and the selection of adequate surgical techniques. This state-of-the-art review aimed to provide a comprehensive analysis of the current understanding of, advancements in, and optimal strategies for CABG in patients with underlying AF. The following topics are considered: stroke prevention, prophylaxis and occurrence of postoperative AF, the role of surgical ablation and left atrial appendage occlusion, and an on-pump vs off-pump strategy. Multiple acute complications can occur in patients with preexisting AF undergoing CABG, each of which can have a significant effect on patient outcomes. Long-term results in these patients and the future perspectives of this scientific area were also addressed. Preoperative arrhythmia should always be considered for surgical ablation because such an approach improves prognosis without increasing perioperative risk. While planning a revascularization strategy, it should be noted that although off-pump coronary artery bypass provides better short-term outcomes, conventional on-pump approach may be beneficial at long-term follow-up. By collecting the current evidence, addressing knowledge gaps, and offering practical recommendations, this state-of-the-art review serves as a valuable resource for clinicians involved in the management of patients with AF undergoing CABG, ultimately contributing to improved outcomes and enhanced patient care.

Background: Transcatheter mitral valve-in-valve (MViV) replacement has emerged as an alternative to redo mitral valve (MV) surgery for the management of failed bioprosthetic MVs. The degree of cardiac remodeling assessed by echocardiography has been shown to have prognostic implications in degenerative mitral regurgitation patients undergoing MV surgery. The impact of transcatheter MViV in patients with degenerative bioprosthetic MV failure on cardiac remodeling and its associated prognosis remains undescribed. Objectives: The aim of this study is to describe the early anatomic and functional changes of the left-sided chambers and right ventricle by echocardiography posttranscatheter MViV intervention and their impact on mortality outcomes. Additionally, we sought to analyze the outcome of heart failure in bioprosthetic MV failure patients undergoing transcatheter MViV replacement. Methods: We analyzed consecutive patients undergoing MViV intervention for symptomatic bioprosthetic MV failure. Echocardiograms before intervention and within 100 days postintervention were analyzed. A chart review was performed to obtain baseline characteristics, follow-up visits, 30-day heart failure and 1-year all-cause mortality outcomes. Results: A total of 62 patients (mean age 69 ± 13 years, 61% male) were included in the study. Most patients were undergoing MViV intervention for prosthetic mitral stenosis n = 48 (77.4%) and the rest for mitral regurgitation or mixed disease. Compared with baseline, significant reductions were observed in median left atrial volume (LAV; 103 [81-129] ml vs. 95.2 [74.5-117.5] ml, p < 0.01) and mean (SD) left atrial conduit strain (9.1% ± 5.2% vs. 10.8% ± 4.8%, p = 0.039) within 100 days postintervention. Early reduction in right ventricular free wall global longitudinal strain and fractional area change also occurred postintervention. No significant change in left ventricular chamber dimensions or ejection fraction was observed. During the 1-year follow up period, 5 (8%) patients died. While baseline LAV was not associated with 1-year all-cause mortality (OR 0.98 CI 0.95-1.01; p = 0.27), a change in LAV in the follow up period was associated with all-cause mortality at 1 year (OR 1.06 CI 1.01-1.12; p = 0.023). At 30 days postintervention, 65% of patients had an improvement in their New York Heart Association functional class. Conclusion: In this retrospective study of patients undergoing transcatheter MViV intervention for failed bioprosthetic MVs, early reverse remodeling of the left atrium occurs within 100 days postintervention and reduction in LAV is associated with reduced all-cause mortality at 1 year. In addition, there is significant improvement in heart failure symptoms at 30 days following intervention but further investigation into the longitudinal remodeling changes and long-term outcomes is needed.
RESUMO
BACKGROUND: Inflammatory bowel disease is a chronic, relapsing, and remitting inflammatory disorder that despite advances in medical therapy often requires hospitalization for treatment of acute flares with intravenous corticosteroids. Many patients will not respond to corticosteroids and require infliximab or cyclosporine as rescue therapy. If medical therapy fails, definitive surgical management is required. Recently, Janus Kinase inhibitors, including upadacitinib, have been proposed as an alternative rescue therapy. AIMS: We hypothesized that upadacitinib may be effective in treating acute severe colitis. METHODS: A retrospective review of 12 inflammatory bowel disease patients admitted for acute severe colitis who received upadacitinib induction therapy was performed. The rates of surgery, repeat or prolonged steroid use, and re-admission within 90 days of index hospitalization were measured. The need for re-induction with upadacitinib, change in medical therapy, rates of clinical remission, change in 6-point partial Mayo score, and laboratory markers of inflammation were measured as secondary outcomes. RESULTS: Five patients met the primary composite endpoint including four patients requiring surgery and one additional patient being unable to withdraw steroids within 90 days of hospital discharge. One patient required re-induction with upadacitinib within 90 days and no patients required change in medical therapy within 90 days. Most patients who did not undergo surgery were in clinical remission within 90 days and showed clinical improvement with decreased 6-point partial Mayo scores. CONCLUSION: Upadacitinib may be effective salvage therapy for acute severe colitis, but larger controlled trials are required to validate these results.

BACKGROUND: The management of aortic stenosis has evolved to stratification by age as reflected in recent societal guidelines. We evaluated age-stratified surgical aortic valve replacement (SAVR) trends and outcomes in patients with bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) from The Society of Thoracic Surgeons Adult Cardiac Surgery Database. METHODS: This cohort included adults (≥18 years) undergoing SAVR for severe aortic stenosis between July 2011 and December 2022. Comparisons were stratified by age (<65 years, 65-79 years, ≥80 years) and BAV or TAV status. Primary end points included operative mortality, composite morbidity and mortality, and permanent stroke. Observed to expected ratios by The Society of Thoracic Surgeons predicted risk of mortality were calculated. RESULTS: In total, 200,849 SAVR patients (55,326 BAV [27.5%], 145,526 TAV [72.5%]) from 1238 participating hospitals met study criteria. Annual SAVR volumes decreased by 45% (19,560 to 10,851) during the study period. The decrease was greatest (96%) for patients ≥80 years of age (4914 to 207). The relative prevalence of BAV was greater in younger patients (<65 years, 69,068 [49.5% BAV]; 65-79 years, 104,382 [19.1% BAV]; ≥80 years, 27,399 [4.5% BAV]). The observed mortality in <80-year-old BAV patients (<65 years, 1.08; 65-79 years, 1.21; ≥80 years, 3.68) was better than the expected mortality rate (<65 years, 1.22; 65-79 years, 1.54; ≥80 years, 3.14). CONCLUSIONS: SAVR volume in the transcatheter era has decreased substantially, particularly for patients ≥80 years old and for those with TAV. Younger patients with BAV have better than expected outcomes, which should be carefully considered during shared decision-making in the treatment of aortic stenosis. SAVR should remain the preferred therapy in this population.

BACKGROUND: Surgical ablation for atrial fibrillation at the time of isolated coronary artery bypass grafting is reluctantly attempted. Meanwhile, complete revascularization is not always possible in these patients. We attempted to counterbalance the long-term benefits of surgical ablation against the risks of incomplete revascularization. METHODS: Atrial fibrillation patients undergoing isolated coronary artery bypass grafting for multivessel disease between 2012 to 2022 and included in the HEart surgery In atrial fibrillation and Supraventricular Tachycardia registry were divided into complete revascularization, complete revascularization with additional grafts, and incomplete revascularization cohorts; these were further split into surgical ablation and non-surgical ablation subgroups. RESULTS: A total of 8,405 patients (78% men; age 69.3 ± 7.9) were included; of those, 5,918 (70.4%) had complete revascularization, and 556 (6.6%) had surgical ablation performed. Number of anastomoses was 2.7 ± 1.2. The median follow-up was 5.1 [interquartile range 2.1-8.8] years. In patients in whom complete revascularization was achieved, surgical ablation was associated with long-term survival benefit: hazard ratio 0.69; 95% confidence intervals (0.50-0.94); P = .020 compared with grafting additional lesions. Similarly, in patients in whom complete revascularization was not achieved, surgical ablation was associated with a long-term survival benefit of 0.68 (0.49-0.94); P = .019. When comparing surgical ablation on top of incomplete revascularization against complete revascularization without additional grafts or surgical ablation, there was no difference between the 2: 0.84 (0.61-1.17); P = .307, which was also consistent in the propensity score-matched analysis: 0.75 (0.39-1.43); P = .379. CONCLUSION: To achieve complete revascularization is of utmost importance. However, when facing incomplete revascularization at the time of coronary artery bypass grafting in a patient with underlying atrial fibrillation, concomitant surgical ablation on top of incomplete revascularization is associated with similar long-term survival as complete revascularization without surgical ablation.

BACKGROUND: Phigenics Validation Test (PVT) VIABLE® (Viability Identification Assay by Legionella Enrichment) is a method to detect viable Legionella bacteria in building water systems. OBJECTIVE: To evaluate PVT VIABLE against the ISO 11731:2017 Water Quality-Enumeration of Legionella reference method for the detection of viable Legionella species in potable and non-potable water. METHODS: PVT VIABLE was tested for inclusivity (n = 50 strains of Legionella) and exclusivity (n = 30 non-target strains), robustness, and stability. A multi-laboratory instrument variation study was performed to evaluate the PCR data. The matrix study was performed on potable and non-potable water samples inoculated with Legionella pneumophila at a low (n = 20) and high fractional level (n = 5). Samples were analyzed using the PVT VIABLE and confirmed using ISO 11731:2017. RESULTS: Statistical analysis showed no difference between PVT VIABLE and ISO 11731:2017 for 100 mL test portions of potable and non-potable water. PVT VIABLE demonstrated high levels of specificity and sensitivity in the inclusivity and exclusivity study. Results of the robustness and stability studies demonstrated the method was sufficiently robust to handle small method changes and met the method claims of stability. CONCLUSION: PVT VIABLE allows the end user to obtain presumptive results for viable Legionella spp. contamination of potable and non-potable water in 2-3 days. HIGHLIGHTS: PVT VIABLE provides viable Legionella results in 2-3 days versus 10-14 days for traditional spread plating. This novel diagnostic tool also differentiates between Legionella pneumophila sg1, Legionella pneumophila sg2-15, and Legionella spp. without the need for additional confirmation steps as outlined in ISO 11731:2017.

INTRODUCTION: Adjuvant (A) multiagent chemotherapy (MC) is the standard of care for patients with pancreatic adenocarcinoma (PDAC). Tolerating MC following a morbid operation may be difficult, thus neoadjuvant (NA) treatment is preferable. This study examined how the timing of chemotherapy was related to the regimen given and ultimately the overall survival (OS). METHODS: The National Cancer Database was queried from 2006 to 2017 for nonmetastatic PDAC patients who underwent surgical resection and received MC or single-agent chemotherapy (SC) pre- or postresection. Predictors of receiving MC were determined using multivariable logistic regression. Five-year OS was evaluated using the Kaplan-Meier and Cox proportional hazards model. RESULTS: A total of 12,440 patients (NA SC, n = 663; NA MC, n = 2313; A SC, n = 6152; A MC, n = 3312) were included. MC utilization increased from 2006-2010 to 2011-2017 (33.1%-49.7%; odds ratio [OR]: 0.59; p < 0.001). Younger age, fewer comorbidities, higher clinical stage, and larger tumor size were all associated with receipt of MC (all p < 0.001), but NA treatment was the greatest predictor (OR 5.18; 95% confidence interval [CI]: 4.63-5.80; p < 0.001). MC was associated with increased median 5-year OS (26.0 vs. 23.9 months; hazard ratio [HR]: 0.92; 95% CI: 0.88-0.96) and NA MC was associated with the highest survival (28.2 months) compared to NA SC (23.3 months), A SC (24.0 months), and A MC (24.6 months; p < 0.001). CONCLUSION: Use and timing of MC contribute to OS in PDAC with an improved 5-year OS compared to SC. The greatest predictor of receiving MC was being given as NA therapy and the greatest survival benefit was the NA MC subgroup. Randomized studies evaluating the timing of effective MC in PDAC are needed.

BACKGROUND: Hypercontractile esophagus (HE) is a disorder of increased esophageal body contractile strength on high-resolution esophageal manometry (HREM). Compartmentalized pressurization (CP) is a pattern with an isobaric contour of >30 mmHg extending from the contractile front to the lower esophageal sphincter on HREM. The relevance of CP to HE has yet to be explored. METHODS: A retrospective review was performed on 830 HREM studies of patients to identify HE. HE patients' CP status and symptoms by Eckardt score (ES) were reviewed. Diagnoses were made using Chicago Classification (CC) v4.0. KEY RESULTS: Forty-seven patients (5.6%) were identified as having HE by CCv3, 30 (3.6%) of which had HE by CCv4. 11/30 HE patients had CP, and 19/30 did not. CP was associated with chronic opioid use (36.4% vs. 5.3% p = 0.047). Presenting ES was greater for HE patients with CP (7 vs. 4). Seven HE patients with CP and 11 without CP were managed medically. ES after medical therapy was higher in HE patients with CP compared to those without CP (9 vs. 0). No HE patients with CP responded to medical therapy. Kaplan-Meier analysis demonstrated significance of this association over time. 83% of all HE patients had all-cause symptom remission. CONCLUSIONS & INFERENCES: HE patients with CP are associated with a higher presenting ES. HE patients with CP do not respond to medical therapy, while HE patients without CP frequently do respond. CP in HE may have prognostic value in determination of treatment strategy for patients with HE.
