Intermediate-Term Outcomes Following Transcatheter Aortic Valve Implantation in Patients with a History of Chest Radiation Therapy: A Propensity Score Matched Analysis.

Chest radiation therapy (XRT) has been associated with a higher rate of mortality following surgical aortic valve replacement. We performed a single-center retrospective analysis of patients with severe AS who underwent TAVI from January 1 2012 to July 31 2020 comparing patients with and without XRT. A total of 915 patients met inclusion criteria, with a total of 50 patients found to have a history of XRT. At a mean follow-up of 2.4 years, unadjusted and propensity score matching analysis demonstrated no differences in mortality, heart failure or bleeding-related hospitalization, overall stroke, and 30-day pacemaker implantation in patients with and without XRT.

Clinical Predictors of Mortality and Heart Failure Hospitalization in Patients With Severe Tricuspid Regurgitation.

Background: There is an incomplete understanding of the predictors of morbidity and mortality in patients with severe tricuspid regurgitation (TR). This study sought to identify key risk factors for all-cause mortality and heart failure (HF) hospitalization among patients with severe TR. Methods: Patients with severe TR were identified from 2 centers, Oregon Health & Science University and Abrazo Health, from January 01, 2016 to December 31, 2018. Patients with any concomitant severe valvular diseases or prior valvular intervention were excluded. Multivariable regression was utilized to identify demographic, clinical, and echocardiographic variables independently associated with all-cause mortality or HF hospitalization. Results: 435 patients with severe TR were followed for a median of 2.8 years. The mean age of the population was 66.9 ± 18.5 years and 58% were female. All-cause mortality was identified in 20.5% of the population. Of the cohort, 35.4% of patients were hospitalized for HF. Isolated tricuspid valve intervention was performed in 2.5% of patients. Independent predictors of all-cause mortality included history of solid tumor (odds ratio [OR] 6.6, 95% confidence interval [CI] 2.1-19.1, p = 0.001), history of peripheral artery disease (OR 3.5, 95% CI 1.2-9.4, p = 0.013), and elevated international normalized ratio in the absence of anticoagulation (OR 1.9, 95% CI 1.2-3.2, p = 0.008). Predictors of HF hospitalization included history of diabetes mellitus (OR 2.2, 95% CI 1.1-4.0, p = 0.014) and history of reduced left ventricular ejection fraction (OR 5.7, 95% CI 2.9-11.7, p < 0.0001). Conclusions: Severe untreated TR is associated with high mortality and frequent HF hospitalizations. Understanding predictors of these outcomes is important to identify patients who may benefit from early tricuspid valve intervention to help improve outcomes in this patient population.

A National Evaluation of Surgeon Experiences in Telemedicine for the Care of Hernia and Abdominal Core Health Patients.

BACKGROUND: Surgeons are increasingly utilizing telemedicine to provide perioperative services to patients. Safety, satisfaction, and feasibility of these programs in general populations have been established, but it is unclear how telemedicine can be integrated into subspecialty care. We report results of a national survey related to telehealth practices among members of the Abdominal Core Health Quality Collaborative (ACHQC). METHODS: Survey responses were analyzed to determine current strategies in telemedicine utilization. Surgeon preferences, perceptions of validity, and identified barriers to implementation of telemedicine were assessed. RESULTS: Forty surgeons within the ACHQC responded, with 90% of respondents reporting use of telemedicine to deliver perioperative care to patients with hernias and abdominal core health concerns. Surgeons appeared to be more comfortable managing preoperative patients with image-confirmed diagnoses of hernias. Surgeons were universally more comfortable delivering postoperative care via telemedicine. Connectivity, patient engagement, and reimbursement were identified as potential barriers to expansion of telemedicine. Seventy-eight percent of respondents reported that they would increase telemedicine utilization if current regulations were maintained in the future. CONCLUSIONS: This study found that hernia specialists are utilizing telemedicine at a higher rate than before the COVID-19 pandemic, with surgeons reporting interest in continued use of this modality beyond the pandemic. These findings suggest that future work in telemedicine optimization may improve the quality of care that can be delivered to patients with abdominal core health concerns.

Clinical Predictors of Mortality in Patients with Moderate to Severe Mitral Regurgitation.

BACKGROUND: Mitral regurgitation is the most common form of valvular heart disease worldwide, however, there is an incomplete understanding of predictors of mortality in this population. This study sought to identify risk factors of mortality in a real-world population with mitral regurgitation. METHODS: All patients with moderate or severe mitral regurgitation were identified at a single center from January 1, 2016 to August 31, 2017. Multivariate regression was performed to evaluate variables independently associated with all-cause mortality. RESULTS: A total of 490 patients with moderate (76.3%) or severe (23.7%) mitral regurgitation due to primary (20.8%) or secondary (79.2%) etiology were identified. The mean age was 66.7 years; 50% were male. At a median follow-up of 3.1 years, the incidence of all-cause mortality was 30.1%, heart failure hospitalization 23.1%, and mitral valve intervention 11.6%. Of 117 variables, multivariate analysis demonstrated 5 that were independently predictive of mortality: baseline creatinine (hazard ratio [HR] 1.2; 95% CI, 1.0-1.3; P = .02), right atrial pressure by echocardiogram (HR 1.3; 95% CI, 1.07-1.55; P = .008), hemoglobin (HR 0.65; 95% CI, 0.52-0.83; P = .001), hospitalization for heart failure (HR 1.6; 95% CI, 1.1-2.4; P = .015), and mitral valve intervention (HR 0.40; 95% CI, 0.16-0.83; P = .049). CONCLUSION: In this retrospective, pragmatic analysis of patients with moderate or severe mitral regurgitation, admission for heart failure exacerbation, elevated right atrial pressure, renal dysfunction, anemia, and lack of mitral valve intervention were independently associated with increased risk of all-cause mortality. Whether these risk factors may better identify select patients who may benefit from more intensive monitoring or earlier intervention should be considered in future studies.

Current Surgical Trainee Perceptions and Experiences in Telehealth.

Introduction:Broad expansion of telehealth technologies has been implemented during the coronavirus disease 2019 (COVID-19) pandemic to allow for physical distancing and limitation of viral transmission within health care facilities. Although telehealth has been studied for its impact on patients, payors, and practitioners, its educational impact is largely unstudied. To better understand the trainee experience and perception of telehealth during the COVID-19 pandemic, we conducted a survey of the membership of the American College of Surgeons Resident and Associate Society (RAS).Methods:An anonymous survey was sent to members of RAS. Descriptive analysis was used to report experiences and perceptions. Chi-square analysis was used to compare cohorts with and without exposure to telehealth.Results:Of the 465 RAS respondents, 292 (62.8%) reported knowledge of telehealth technologies at their institutions. The majority of these respondents experienced a decrease in in-person clinic volume (94.4%) and an associated increase in virtual clinic volume (95.7%) related to the COVID-19 pandemic. Trainee integration into telehealth workflows increased drastically from prepandemic levels (11% vs. 54.5%, p < 0.001). Likelihood of trainee exposure to telehealth was associated with university-based training programs or larger program size. Trainees demonstrated a desire for more integration and development of curricula.Conclusions:These data serve as the first description of surgical trainee experience with, and opinion of, telehealth. Trainees recognize the importance of their integration and training in telehealth. These results should be used to guide the development of workflows and curricula that integrate trainees into telemedicine clinics.
