Tricuspid regurgitation burden following transcatheter aortic valve replacement requiring early pacemaker implantation.

Background: Conduction abnormality requiring the implantation of a permanent pacemaker (PPM) is a well-known and clinically important complication of transcatheter aortic valve replacement (TAVR). However, PPM implantation may result in lead-associated tricuspid valve regurgitation (TR). This study sought to determine the incidence and progression of TR following PPM implantation after TAVR. Methods: This was a retrospective review of all echocardiograms of patients who underwent PPM following TAVR at the Baylor Scott & White hospitals from 2012 to 2021. The primary endpoint was TR progression at 30 days and 1 year. A subanalysis comparing the change in TR progression between small and large TAVR devices was also conducted. Secondary outcomes included all-cause death at 30 days and 1 year. Results: Out of the 2744 patients who underwent TAVR between April 2012 and August 2021, 177 patients (6.5%) subsequently received a new PPM. There was a statistically significant progression of TR at 1-year follow-up (McNemar's P value = 0.02). TR progression rates were comparable between the small and large valve groups at 1-year follow-up (4% vs 11%, P = 0.09, respectively). Conclusion: In this single healthcare system study, we demonstrated a significant progression of TR in patients with PPM post TAVR at 1 year.

Three-year outcomes of de novo tacrolimus extended-release tablets (LCPT) compared to twice-daily tacrolimus in adult heart transplantation.

BACKGROUND: Extended-release tacrolimus for prophylaxis of allograft rejection in heart transplant (HT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release (IR-) tacrolimus. We compared long-term efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. METHODS: 25 prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 3 years following transplant was compared between groups using non-inferiority analysis. RESULTS: LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 16% (90%CI, -37%, -1%, non-inferiority p = 0.002) up to 3 years following heart transplant. Up to 3-years post-transplant, 14 patients remained on once-daily LCPT and 10 patients were switched to IR-tacrolimus due to lack of insurance coverage. There were no significant differences in the rate of chronic kidney disease requiring dialysis, cytomegalovirus requiring treatment, cardiac allograft vasculopathy, and malignancy within 3 years following transplant. CONCLUSION: LCPT is non-inferior in efficacy to IR-tacrolimus in heart transplantation with a similar safety profile. Narrowly-constrained FDA labels specific to kidney transplant remain a barrier to consistent access to many immunosuppressant medications for recipients of non-kidney solid organs. We recommend the FDA consider developing facile pathways for expanding the approved label of extended-release tacrolimus formulations to heart transplant recipients.

Early elevated donor-derived cell-free DNA levels in heart transplant recipients following precision-controlled cardiac transport system or ice-cooled organ transport.

BACKGROUND: Recent innovations in temperature-controlled cardiac transportation allow for static hypothermic preservation of transplant organs during transportation. We assessed differences in donor-derived cell-free DNA (dd-cfDNA) using the SherpaPak cardiac transport system (SCTS) and traditional ice transportation. METHODS: Single-organ heart transplant recipients between January 2020 and January 2022 were included if they had dd-cfDNA measures ≤6 weeks post-transplant along with the baseline biopsy at 6 weeks as part of the surveillance protocol and no biopsy-confirmed rejection ≤90 days. Elevated dd-cfDNA ≥.20% were compared between groups using logistic regression including a subject effect. RESULTS: Of 65 hearts transplanted, 30 were transported with SCTS and 35 on ice. Recipient characteristics were similar between groups. Donors in the SCTS group were older (34 vs. 40 years, p = .04) with a longer total ischemic time (171 vs. 212 min, p = .002). Recipients in the SCTS group had a greater risk of elevated dd-cfDNA unadjusted and adjusted for donor age, and prolonged ischemic times > 3.5 h (Unadjusted odds ratio: 4.9, 95%-CI: 1.08-22.5, p = .039 and Adjusted odds ratio: 5.5, 95%-CI: 1.03-29.6, p = .046). Primary graft dysfunction rates and 1-year mortality were comparable between groups. CONCLUSION: Elevated dd-cfDNA in patients procured with SCTS may indicate that graft injury was not negated relative to ice transport. However, there were no clinical differences noted in short or long-term outcomes including mortality despite a longer ischemic time in the SCTS group.

Bioimpedance Spectroscopy in Heart Transplantation: Posttransplant Changes in Body Composition and Effects in Outcomes.

BACKGROUND: Bioimpedance spectroscopy yields measurements of fat-free mass, fat mass, phase angle, and other measures. Bioimpedance spectroscopy has been validated as a preoperative assessment tool in cardiac surgical studies, in which low phase angle predicted morbidity and mortality. No studies have evaluated bioimpedance spectroscopy following heart transplantation. METHODS: We evaluated body composition, nutrition status (Subjective Global Assessment, body mass index, midarm muscle circumference, and triceps skinfolds), and functional status (handgrip strength and 6-min walk test) in 60 adults. Body composition measurements via a 256-frequency bioimpedance spectroscopy device included fat and fat-free mass as well as phase angle calculated at 50 kHz. Testing was completed at baseline and 1, 3, 6, and 12 mo following heart transplantation. Mortality and hospital readmissions were analyzed. RESULTS: Phase angle and fat mass increased while fat-free mass decreased; grip strength and 6-min walk test improved after transplantation (all P < 0.001). Improvement in phase angle in the first month postoperatively was associated with reduced risk of readmission. Low perioperative and 1-mo phase angles were associated with prolonged posttransplant length of stay (median: 13 versus 10 d, P = 0.03), increased infection-related readmissions (40% versus 5%, P = 0.001), and increased 4-y mortality (30% versus 5%, P = 0.01). CONCLUSIONS: Phase angle, grip strength, and 6-min walk test distance improved after heart transplantation. Low phase angle appears to be associated with suboptimal outcomes and may be a feasible and affordable method to predict outcomes. Further research should ascertain whether preoperative phase angle can predict outcomes.

Outcomes After Supratentorial Craniotomy for Primary Malignant Brain Tumor Resection in Adult Patients: A National Surgical Quality Improvement Program Analysis.

BACKGROUND: The rate of complications remains significant after craniotomy for supratentorial primary malignant brain tumors despite recent advances. OBJECTIVE: The goal of this study is to characterize factors associated with these complications. METHODS: Data were extracted from the National Surgical Quality Improvement Program database from 2016 to 2019. Patients who underwent a craniotomy for resection of supratentorial primary malignant brain tumors were included. Covariates included demographics/comorbidities, preoperative laboratory values, American Society of Anesthesiologists (ASA) classification, operative time, and postoperative complications. Multivariable logistic regression with backward and forward selection was used to evaluate independent predictors of death, prolonged hospitalization, postoperative stroke with neurologic deficit (CVA), and unplanned readmission. Predictive fit of the model was evaluated using the area under the receiver operating curve (AUC). RESULTS: Of 8965 included cases, the 30-day postoperative risks were 1.9% for CVA, 10.1% for unplanned readmission, 1.2% for prolonged hospitalization, and 2.4% for death. Age, ASA category, disseminated cancer, preoperative functional dependence, and postoperative respiratory complications were predictors of 30-day mortality (AUC, 0.83; P < 0.001). CVA was best predicted by increased operation time (P < 0.001), age, ASA category, and recent weight loss (AUC, 0.63; P = 0.009). Prolonged hospitalization was predicted by nonelective surgery status, time from admission to surgery, reintubation, and postoperative sepsis (AUC, 0.78; P < 0.001). Unplanned readmission was predicted by chronic steroid use, postoperative thrombotic complications after surgery, organ/space surgical site infection, deep vein thrombosis, postoperative systemic sepsis, and septic shock (AUC, 0.68; P < 0.001). CONCLUSIONS: Our study identifies predictors of major 30-day complications after craniotomy for this subset of patients with brain tumor.

The Utility of Home Sleep Apnea Testing in the Advanced Heart Failure Populations.

Untreated sleep disorders form a risk of coronary artery disease, hypertension, obesity, and diabetes mellitus. Access to polysomnography is limited, especially during the COVID-19 pandemic, with home sleep apnea testing (HSAT) being a potentially viable alternative. We describe an HSAT protocol in patients with advanced heart failure (HF). In a single-center, observational analysis between 2019 and 2021 in patients with advanced HF and heart transplant (HT), 135 screened positive on the STOP-Bang sleep survey and underwent a validated HSAT (WatchPAT, ZOLL-Itamar). HSAT was successful in 123 patients (97.6%), of whom 112 (91.1%; 84 HF and 28 HT) tested positive for sleep apnea. A total of 91% of sleep apnea cases were obstructive, and 63% were moderate to severe. Multivariable linear regression showed that the apnea hypopnea index was 34% lower in the HT group than in the HF group (p = 0.046) after adjusting for gender, and that this effect persisted in White patients but not among African-Americans. Patient characteristics were similar between groups, with coronary artery disease, diabetes mellitus, and hypertension as the most prevalent co-morbidities. In conclusion, sleep apnea remains prevalent in patients with HF with a high co-morbidity burden. HSAT is a feasible and effective tool for screening and diagnosis in this population.

Distal Versus Proximal Radial Artery Access for Cardiac Catheterization and Intervention: Design and Rationale of the DIPRA Trial.

BACKGROUND: Radial artery (RA) catheterization is the access of choice over femoral artery access for most interventional vascular procedures given its safety and faster patient recovery. There has been growing interest in distal radial artery (dRA) access as an alternative to the conventional proximal radial artery (pRA) access. Preserving the RA is important which serves as a potential conduit for future coronary artery bypass surgery, dialysis conduit or preserve the artery for future cardiovascular procedures. The dRA runs in close proximity to the radial nerve, which raises the concern of potential detrimental effects on hand function. STUDY DESIGN: The Distal versus Proximal Radial Artery Access for cardiac catheterization and intervention (DIPRA) trial is a prospective, randomized, parallel-controlled, open-label, single center study evaluating the outcomes of hand function and effectiveness of dRA compared to pRA access in patients undergoing cardiac catheterization. The eligible subjects will be randomized to dRA and pRA access in a (1:1) fashion. The primary end point is an evaluation of hand function at one and twelve months follow-up. Secondary end points include rates of access site hematoma, access site bleeding, other vascular access complications, arterial access success rate, and RA occlusion at one and twelve months follow up. CONCLUSION: Effects of dRA on hand function remains unknown and it's use questionable in the presence of a widely accepted pRA. DIPRA trial is designed to determine the safety and effectiveness of dRA for diagnostic and interventional cardiovascular procedures compared to the standard of care pRA.

Urinary Cell-Cycle Arrest Biomarkers as Early Predictors of Acute Kidney Injury After Ventricular Assist Device Implantation or Cardiac Transplantation.

OBJECTIVES: Acute kidney injury (AKI) remains a leading source of morbidity and mortality after cardiothoracic surgery. Insulin-like growth factor-binding protein 7 (IGFBP7), and tissue inhibitor of metalloproteinases-2 (TIMP-2), are novel early-phase renal biomarkers that have been validated as sensitive predictors of AKI. Here the authors studied the efficacy of these biomarkers for predicting AKI after left ventricular assist device (LVAD) implantation and cardiac transplantation. DESIGN/SETTING/PARTICIPANTS/INTERVENTIONS: This was a prospective study of 73 patients undergoing LVAD implantation (n = 37) or heart transplant (n = 36) from 2016 to 2017 at the authors' center. TIMP-2 and IGFBP7 were measured with the NephroCheck Test on urine samples before surgery and one-to-six hours after surgery. NephroCheck scores were assessed as predictors of moderate/severe AKI (Kidney Disease International Global Outcomes 2/3 creatinine criteria) within 48 hours of surgery, and the association with survival to one year was investigated. MEASUREMENTS AND MAIN RESULTS: The LVAD and transplant cohorts overall were similar in demographics and baseline creatinine (p > 0.05), with the exception of having more African-American patients in the LVAD arm (p = 0.003). Eleven (30%) LVAD and 16 (44%) transplant patients developed moderate/severe AKI. Overall, AKI was associated with postsurgery NephroCheck (odds ratio [95% confidence interval] for 0.1 mg/dL increase: 1.36 [1.04-1.79]; p = 0.03), but not with baseline NephroCheck (p = 0.92). When analyzed by cohort, this effect remained for LVAD (1.68 [1.05-2.71]; p = 0.03) but not for transplant (p = 0.15). Receiver operating characteristic analysis showed postoperative NephroCheck to be superior to baseline creatinine in LVAD (p = 0.046). Furthermore, an increase of 0.1 mg/dL in postoperative NephroCheck was associated with a 10% increase in the risk of mortality (adjusted hazard ratio: 1.11 [1.01-1.21]; p = 0.04) independent of age and body mass index. CONCLUSION: Assessment of TIMP-2 and IGFBP7 within six hours after surgery appeared effective at predicting AKI in patients with LVADs. Larger studies are warranted to validate these findings.

A system-wide extracorporeal membrane oxygenation quality collaborative improves patient outcomes.

OBJECTIVE: Extracorporeal membrane oxygenation (ECMO) use in adult patient populations has grown rapidly with wide variation in practices and outcomes. We evaluated the impact on patient outcomes, resource use, and costs of an initiative to coordinate and standardize best practices across ECMO programs within a large integrated health care system. METHODS: The ECMO Collaborative Project brought clinicians and service-line leaders from 4 programs within a single health care system together with operational subject matter experts tasked with developing and implementing standardized guidelines, order sets, and an internal database to support an automated quarterly report card. Patient outcomes, resource use, and financial measures were compared for the 16 months before (January 2017 to April 2018; "precollaborative," n = 185) versus the 14 months after (November 2018 to December 2019, "postcollaborative," n = 243) a 6-month implementation and blanking period. Subset analyses were performed for venoarterial ECMO, venovenous ECMO, and extracorporeal cardiopulmonary resuscitation. RESULTS: Survival to discharge/transfer increased significantly (in-hospital mortality hazard ratio, 0.75; 95% confidence interval [95% CI], 0.58-0.99) for the postcollaborative versus the precollaborative period (107/185, 57.8% vs 113/243, 46.5%, P = .03), predominantly due to improvement among patients receiving venoarterial ECMO (hazard ratio, 0.61; 95% CI, 0.41-0.91). The percentage of patients successfully weaned from ECMO increased from 58.9% (109/185) to 70% (170/243), P = .02. Complication rates decreased by 40% (incidence rate ratio, 0.60; 95% CI, 0.49-0.72). No significant changes were observed in ECMO duration, intensive care unit or hospital length of stay, or cost-per-case; payment-per-case and contribution-margin-per-case both decreased significantly. CONCLUSIONS: The ECMO Collaborative Project improved survival to discharge/transfer, weaning rates and complications, without additional costs, through coordination and standardization across ECMO programs within a health care system.

Observed elevated donor-derived cell free DNA in orthotopic heart transplant recipients without clinical evidence of rejection.

Donor-derived cell free DNA (dd-cfDNA) has rapidly become part of rejection surveillance following orthotopic heart transplantation. However, some patients show elevated dd-cfDNA without clinical evidence of rejection. With the aim to provide a clinical description of this subpopulation, we retrospectively analyzed 35 cardiac transplant recipients at our center who experienced elevated (≥.20%) dd-cfDNA in the absence of clinical rejection, out of a total 106 recipients who had dd-cfDNA results available during the first year. The median time to first elevated dd-cfDNA level was 46 days, and the highest dd-cfDNA recorded within 1 year was .31% [inter-quartile range, .23-.45]. Twenty-two (63%) patients experienced infections (cytomegalovirus (CMV) or other), and 16 (46%) presented with de novo donor-specific antibodies. Cluster analysis revealed four distinct groups characterized by (a) subclinical rejection with 50% CMV (n = 16), (b) non-CMV infections and the longest time to first elevated dd-cfDNA (187 days) (n = 8), (c) right ventricular dysfunction (n = 6), and (d) women who showed the youngest median age (45 years) and highest median dd-cfDNA (.50%) (n = 5). Continued prospective analysis is needed to determine if these observations warrant changes in patient management to optimize the utilization of this vital non-invasive graft surveillance tool.

De novo tacrolimus extended-release tablets (LCPT) versus twice-daily tacrolimus in adult heart transplantation: Results of a single-center non-inferiority matched control trial.

Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. Twenty-five prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 1 year was compared using non-inferiority analysis. LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 20% (90% CI: -40%, -.5%; non-inferiority P = .001). Tacrolimus trough levels peaked at 2-3 months and were higher in LCPT (median 14.5 vs. 12.7 ng/ml; P = .03) with similar dose levels (LCPT vs. IR-tacrolimus: .08 vs. .09 mg/kg/day; P = .33). Cardiovascular-related readmissions were reduced by 62% (P = .046) in LCPT patients. The complication rate per transplant admission and all-cause readmission rate did not differ significantly. These results suggest that LCPT is non-inferior in efficacy to IR-tacrolimus with a similar safety profile and improved bioavailability in OHT.

Pneumothorax and Pneumomediastinum in COVID-19 Suggest a Pneumocystic Pathology.

OBJECTIVE: To determine whether the apparent excess incidence of pneumothorax and pneumomediastinum in patients with coronavirus disease 2019 (COVID-19) is explained adequately by iatrogenic causes vs reflecting sequelae of severe acute respiratory syndrome coronavirus 2 infection. PATIENTS AND METHODS: We retrospectively reviewed patients within our health care system from March 15, 2020, through May 31, 2020, who had a diagnosis of pneumothorax or pneumomediastinum during hospitalization for confirmed COVID-19 infection with attention to timing of pneumothorax and pneumomediastinum; presence, laterality, and placement, or attempts at central lines; and presence of mechanical ventilation before the event. RESULTS: We report clinical data and outcomes from 9 hospitalized patients with COVID-19 who developed pneumothorax and/or pneumomediastinum among more than 1200 hospitalized patients admitted within our hospital system early in the pandemic. Many events were inexplicable by iatrogenic needle injury, including 1 spontaneous case without central line access or mechanical ventilation. One occurred before central line placement, 2 in patients with only a peripherally inserted central line, and 1 contralateral to a classic central line. Three of these 9 patients died of complications of COVID-19 during their hospital stay. CONCLUSION: With COVID-19 affecting the peripheral lung pneumocytes, patients are vulnerable to develop pneumothorax or pneumomediastinum irrespective of their central line access site. We hypothesize that COVID-19 hyperinflammation, coupled with the viral tropism that includes avid involvement of peripheral lung pneumocytes, induces a predisposition to peripheral bronchoalveolar communication and consequent viral hyperinflammatory-triggered pneumothorax and pneumomediastinum.

Impact of risk-stratified mycophenolate dosing in heart transplantation.

Mycophenolate mofetil (MMF), the prodrug of mycophenolic acid, is a highly effective immunosuppressive agent in heart transplant therapy. While the FDA approved dose is 1500 mg twice daily, dosing is often reduced due to dose-dependent adverse effects. However, empiric MMF dose reductions may lead to sub-therapeutic dosing and impair clinical outcomes. Our single center protocolized a risk-stratified approach based on age and weight to dose 500 mg twice daily or 1000 mg twice daily to patients after heart transplantation. This retrospective single-center study analyzed 140 consecutive heart transplant patients who were initiated on our risk-stratified MMF protocol post-transplant. The analysis revealed that the composite rate of biopsy-proven rejection, graft loss, or mortality at 1-year post-transplantation was similar between the two groups. Incidence of neutropenia, thrombocytopenia, infection, cardiac allograft vasculopathy, or acute kidney injury by 1-year also showed similar results between the two groups. Risk-stratification of MMF dosing appears to be a safe and effective strategy after heart transplantation.

Impact of antimicrobial selection for prophylaxis of left ventricular assist device surgical infections.

BACKGROUND: Surgical site infections (SSIs) after left ventricular assist device (LVAD) implantation are associated with high mortality, while surgical prophylaxis is variable. METHODS: This retrospective study included adult patients who underwent LVAD implantation at a single center. We compared outcomes in patients who received narrow antimicrobial prophylaxis (cefazolin, vancomycin, or both) to those who received broad antimicrobial prophylaxis (any antimicrobial combination targeting gram-positive and gram-negative organisms not included in the narrow group) at 30-day and 1-year postimplantation. Cox-proportional hazards models and log-rank tests were used for survival analysis. RESULTS: Among the 39 and 65 patients comprising narrow and broad groups respectively, there was no difference in rate of SSI at 30 days (6.2% vs. 12.8%, p = .290) and 1 year (16.9% vs. 25.6%, p = .435). Comparing narrow to broad prophylaxis, the risk of mortality (hazard ratio [HR] = 0.44, 95% confidence interval [CI] = 0.15-1.35, logrank p = .14), and composite of mortality and infection was reduced (HR = 0.92, 95% CI = 0.45-1.88, logrank p = .83), but did not reach statistical significance. Most culture positive infections were due to gram-positive bacteria (70%) and the most common organisms were the Staphylococcus spp (47%). There were no significant differences in the rate of SSI at 1-year (p = 1.00) and mortality (p = .33) by device type. CONCLUSIONS: The rates of infection and all-cause mortality were not different between patients who received narrow or broad prophylaxis. This highlights an opportunity for institutions to narrow their surgical infection prophylaxis protocols to primarily cover gram-positive organisms.

ALLY in fighting COVID-19: magnitude of albumin decline and lymphopenia (ALLY) predict progression to critical disease.

The global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic leading to coronavirus disease 2019 (COVID-19) is straining hospitals. Judicious resource allocation is paramount but difficult due to the unpredictable disease course. Once hospitalized, discerning which patients may progress to critical disease would be valuable for resource planning. Medical records were reviewed for consecutive hospitalized patients with COVID-19 in a large healthcare system in Texas. The main outcome was progression to critical disease within 10 days from admission. Albumin trends from admission to 7 days were analyzed using mixed-effects models, and progression to critical disease was modeled by multivariable logistic regression of laboratory results. Risk models were evaluated in an independent group. Of 153 non-critical patients, 28 (18%) progressed to critical disease. The rate of decrease in mean baseline-corrected (Δ) albumin was -0.08 g/dL/day (95% CI -0.11 to -0.04; p<0.001) or four times faster, in those who progressed compared with those who did not progress. A model of Δ albumin combined with lymphocyte percentage predicting progression to critical disease was validated in 60 separate patients (sensitivity, 0.70; specificity, 0.74). ALLY (delta albumin and lymphocyte percentage) is a simple tool to identify patients with COVID-19 at higher risk of disease progression when: (1) a 0.9 g/dL or greater albumin drop from baseline within 5 days of admission or (2) baseline lymphocyte of ≤10% is observed. The ALLY tool identified >70% of hospitalized cases that progressed to critical COVID-19 disease. We recommend prospectively tracking albumin. This is a globally applicable tool for all healthcare systems.

Usefulness of Thoracic Aortic Calcium to Predict 1-Year Mortality After Transcatheter Aortic Valve Implantation.

In patients who underwent transcatheter aortic valve implantation (TAVI), vascular disease is associated with increased risk of mortality. Thoracic aortic calcification (TAC), an objective surrogate of vascular disease, could be a predictor of mortality after TAVI. We aimed to analyze the association between TAC burden and 1-year all-cause mortality in patients who underwent TAVI in a US population. From July 2015 through July 2017, a retrospective review of TAVI procedures was performed at Baylor Scott & White-The Heart Hospital, Plano, Texas. Patients were analyzed for comorbidities, cardiac risk factors, and 30-day and 1-year all-cause mortality. Restricted cubic splines analysis was used to define low, moderate, and high TAC categories. The association between TAC and survival was evaluated using unadjusted and adjusted Cox models. A total of 431 TAVI procedures were performed, of which TAC was measured in 374 (81%) patients. Median (interquartile range) age was 82 (77, 87) years, and 51% were male. Median (interquartile range) STS PROM was 5.6 (4.1, 8.2) %. Overall 30-day and 1-year all-cause mortality was 1% and 10%, respectively. TAC was categorized as low (<1.6 cm3), moderate (1.6 to 2.9 cm3), and high (>2.9 cm3). At 1 year, all-cause mortality was 16% in patients with high TAC compared with 6% in the low and moderate TAC categories (p = 0.008). Unadjusted and adjusted Cox regression analysis showed a significant increase in mortality for patients with high TAC compared with low TAC (hazard ratio 2.98, 95% confidence interval [1.34-6.63]), but not significant compared with moderate TAC group. TAC is a predictor of late mortality after TAVI. In conclusion, adding TAC to preoperative evaluation may provide an objective, reproducible, and potentially widely available tool that can help in shared decision-making.
