Racial disparities in surgical treatment of type A acute aortic dissectionCentral MessagePerspective

Objective: To determine whether there are racial disparities associated with mortality, cost, and length of hospital stay after surgical repair of type A acute aortic dissection (TAAAD). Methods: Patient data from 2015 to 2018 were collected using the National Inpatient Sample. In-hospital mortality was the primary outcome. Multivariable logistical modeling was used to identify factors independently associated with mortality. Results: Among 3952 admissions, 2520 (63%) were White, 848 (21%) were Black/African American, 310 (8%) were Hispanic, 146 (4%) were Asian and Pacific Islander (API), and 128 (3%) were classified as Other. Black/African American and Hispanic admissions presented with TAAAD at a median age of 54 years and 55 years, respectively, whereas White and API admissions presented at a median age of 64 years and 63 years, respectively (P < .0001). Additionally, there were higher percentages of Black/African American (54%; n = 450) and Hispanic (32%; n = 94) admissions living in ZIP codes with the lowest median household income quartile. Despite these differences on presentation, when adjusting for age and comorbidity, there was no independent association between race and in-hospital mortality and no significant interactions between race and income on in-hospital mortality. Conclusions: Black and Hispanic admissions present with TAAAD a decade earlier than White and API admissions. Additionally, Black and Hispanic TAAAD admissions are more likely to come from lower-income households. After adjusting for relevant cofactors, there was no independent association between race and in-hospital mortality after surgical treatment of TAAAD

Adoption and Usage of Video Telehealth in a Large, Academic Department of Surgery

Objectives:. To understand the impact that video telehealth has on outpatient visit volume and reimbursement as a method of maintaining care. Background:. As the coronavirus disease 2019 (COVID-19) spread across the United States starting in 2020, it caused numerous areas of medicine and healthcare to reexamine how we provide care to patients across all disciplines. One method clinicians used to rapidly adapt to these transformed settings was video telehealth, which was previously rarely used. Methods:. This retrospective review examined outpatient volume and reimbursement data of a large, academic department of surgery. The study reviewed data during 2 time periods: pre-COVID-19 (February 1, 2020, to March 15, 2020) and COVID-19 (March 16, 2020, to April 30, 2020). Results:. During the period of February 1 to April 30, 13,193 outpatient visits were analyzed. The pre-COVID-19 group contained 9041 (68.5%) visits, whereas the COVID-19 group contained 4152 (31.4%) visits. All divisions noted a drop in visit volume from pre-COVID-19 compared with COVID-19. There was rapid adoption of video telehealth during COVID-19, which made up most patient visits during that time (61.3%). We also found that video telehealth led to significant reimbursements while also allowing patients in numerous states to receive care. Conclusions:. Previously, video telehealth was used by clinicians in a small portion of outpatient visits. However, safety concerns surrounding COVID-19 forced multiple changes to the way care is provided. Although outpatient volume at our center was less than that before the pandemic, video telehealth was rapidly adopted by providers and allowed for safe and effective outpatient care to patients in a high number of states while still being reimbursed at a high rate

Central aortic versus axillary artery cannulation for aortic arch surgeryCentral MessagePerspective

Objective: Central aortic cannulation for aortic arch surgery has become more popular over the last decade; however, evidence comparing it with axillary artery cannulation remains equivocal. This study compares outcomes of patients who underwent axillary artery and central aortic cannulation for cardiopulmonary bypass during arch surgery. Methods: A retrospective review of 764 patients who underwent aortic arch surgery at our institution between 2005 and 2020 was performed. The primary outcome was failure to achieve uneventful recovery, defined as having experienced at least 1 of the following: in-hospital mortality, stroke, transient ischemic attack, bleeding requiring reoperation, prolonged ventilation, renal failure, mediastinitis, surgical site infection, and pacemaker or implantable cardiac defibrillator implantation. Propensity score matching was used to account for baseline differences across groups. A subgroup analysis of patients undergoing surgery for aneurysmal disease was performed. Results: Before matching, the aorta group had more urgent or emergency operations (P = .039), fewer root replacements (P < .001), and more aortic valve replacements (P < .001). After successful matching, there was no difference between the axillary and aorta groups in failure to achieve uneventful recovery, 33% versus 35% (P = .766), in-hospital mortality, 5.3% versus 5.3% (P = 1), or stroke, 8.3% versus 5.3% (P = .264). There were more surgical site infections in the axillary group, 4.8% versus 0.4% (P = .008). Similar results were seen in the aneurysm cohort with no differences in postoperative outcomes between groups. Conclusions: Aortic cannulation has a safety profile similar to that of axillary arterial cannulation in aortic arch surgery

Effect of venoarterial extracorporeal membrane oxygenation initiation timing on tricuspid valve surgery outcomesCentral MessagePerspective

Objectives: Tricuspid valve surgery is associated with high rates of shock and in-hospital mortality. Early initiation of venoarterial extracorporeal membrane oxygenation after surgery may provide right ventricular support and improve survival. We evaluated mortality in patients undergoing tricuspid valve surgery based on the timing of venoarterial extracorporeal membrane oxygenation. Methods: All consecutive adult patients undergoing isolated or combined surgical tricuspid valve repair or replacement from 2010 to 2022 requiring venoarterial extracorporeal membrane oxygenation use were stratified by initiation in the operating room (Early) versus outside of the operating room (Late). Variables associated with in-hospital mortality were explored using logistic regression. Results: There were 47 patients who required venoarterial extracorporeal membrane oxygenation: 31 Early and 16 Late. Mean age was 55.6 years (standard deviation, 16.8), 25 (54.3%) were in New York Heart Association class III/IV, 30 (60.8%) had left-sided valve disease, and 11 (23.4%) had undergone prior cardiac surgery. Median left ventricular ejection fraction was 60.0% (interquartile range, 45-65), right ventricular size was moderately to severely increased in 26 patients (60.5%), and right ventricular function was moderately to severely reduced in 24 patients (51.1%). Concomitant left-sided valve surgery was performed in 25 patients (53.2%). There were no differences in baseline characteristics or invasive measurements immediately before surgery between the Early and Late groups. Venoarterial extracorporeal membrane oxygenation was initiated 194 (23.0-840.0) minutes after cardiopulmonary bypass in the Late venoarterial extracorporeal membrane oxygenation group. In-hospital mortality was 35.5% (n = 11) in the Early group versus 68.8% (n = 11) in the Late group (P = .037). Late venoarterial extracorporeal membrane oxygenation was associated with in-hospital mortality (odds ratio, 4.00; 1.10-14.50; P = .035). Conclusions: Early postoperative initiation of venoarterial extracorporeal membrane oxygenation after tricuspid valve surgery in high-risk patients may be associated with improvement in postoperative hemodynamics and in-hospital mortality

Hospital characteristics associated with failure to rescue in cardiac surgeryCentral MessagePerspective

Objective: The study objective was to examine the association between hospital processes of care and failure to rescue in a diverse, multi-institutional cardiac surgery network. Methods: Failure to rescue was defined as an operative mortality after 1 or more of 4 complications: prolonged ventilation, stroke, renal failure, and unplanned reoperation. Society of Thoracic Surgeons data from 20,950 consecutive patients in the Columbia HeartSource network who underwent 1 of 7 cardiac operations—coronary artery bypass grafting, aortic valve replacement ± coronary artery bypass grafting, mitral valve repair or replacement ± coronary artery bypass grafting—were analyzed to calculate failure to rescue rates. Hospital-specific characteristics were ascertained by survey method. Multivariable mixed-effects logistic models assessed the association of these hospital characteristics with failure to rescue while adjusting for patient-related factors known to be associated with mortality. Results: Failure to rescue rates at affiliate hospitals ranged from 5.45% to 21.74% (median, 12.5%; interquartile range, 6.9%). When controlling for Society of Thoracic Surgeons–predicted risk of mortality with hospital as a random effect, 4 hospital characteristics were found to be associated with lower failure to rescue rates; the presence of cardiac-trained anesthesiologists (odds ratio, 0.41; CI, 0.31-0.55, P < .001), availability of extracorporeal membrane oxygenation mechanical circulatory support (odds ratio, 0.41; CI, 0.31-0.54, P < .001), ratio of intensive care unit beds to intensivists (odds ratio, 0.87; CI, 0.76-0.99, P = .039), and total number of intensive care unit beds (odds ratio, 0.97; CI, 0.96-0.99, P = .002) Conclusions: In a diverse multi-institutional cardiac surgical network, we were able to identify specific hospital processes of care associated with failure to rescue, even when adjusting for patient-related predictors of operative mortality

Do age and functional dependence affect outcomes of simultaneous heart–kidney transplantation?Central MessagePerspective

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 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

Outcomes of a Combined Approach of Percutaneous Coronary Revascularization and Cardiac Valve Surgery.

A subset of patients requiring coronary revascularization and valve surgery may benefit from a combined approach of percutaneous coronary intervention (PCI) and valve surgery, as opposed to the standard median sternotomy approach of combined coronary artery bypass and valve surgery. To evaluate its potential benefits and limitations, a literature search was performed using PubMed, EMBASE, Ovid, and the Cochrane library, through March 2016 to identify all studies involving a combined approach of PCI and valve surgery in patients with coronary artery and valvular disease. There were five studies included in the study with a total of 324 patients, of which 75 (23.1%) had a history of previous cardiac surgery. The interval between PCI and surgery ranged from simultaneous intervention to a median of 38 days (interquartile range, 18-65 days). The surgical approach performed consisted of a minimally invasive one or median sternotomy. There were 275 single valve surgery (84.9%) and 49 double-valve surgery (15.1%) with a 30-day mortality ranging from 0% to 5.5%. The 1-year survival ranged from 78% to 96%, and the follow-up period ranged from 1.3 to 5 years. Herein, we present a review of the literature using this technique
