Subacute groin complications associated with extracorporeal membrane oxygenation (ECMO) cannulation are well recognized, yet their effects on clinical outcomes remain unknown. This single-center, retrospective study reviewed all patients receiving venoarterial ECMO from 01/2017 to 02/2020. Cohorts analyzed included transplanted patients (TPs) and non-transplanted patients (N-TPs) who did or did not develop ECMO-related subacute groin complications. Standard descriptive statistics were used for comparisons. Logistic regressions identified associated risk factors. Overall, 82/367 (22.3%) ECMO patients developed subacute groin complications, including 25/82 (30.5%) seromas/lymphoceles, 32/82 (39.0%) hematomas, 18/82 (22.0%) infections, and 7/82 (8.5%) non-specified collections. Of these, 20/82 (24.4%) underwent surgical interventions, most of which were muscle flaps (14/20, 70.0%). TPs had a higher incidence of subacute groin complications than N-TPs (14/28, 50.0% vs. 68/339, 20.1%, P = 0.001). Seromas/lymphoceles more often developed in TPs than N-TPs (10/14, 71.4% vs. 15/68, 22.1%, P = 0.001). Most patients with subacute groin complications survived to discharge (60/68, 88.2%). N-TPs who developed subacute groin complications had longer post-ECMO lengths of stay than those who did not (34 days, IQR 16–53 days vs. 17 days, IQR 8–34 days, P < 0.001). Post-ECMO length of stay was also longer among patients who underwent related surgical interventions compared to those who did not (50 days, IQR 35–67 days vs. 29 days, IQR 16–49 days, P = 0.007). Transplantation was the strongest risk factor for developing subacute groin complications (OR 3.91, CI95% 1.52–10.04, P = 0.005). Subacute groin complications and related surgical interventions are common after ECMO cannulation and are associated with longer hospital stays. When surgical management is warranted, muscle flaps may reduce lengths of stay compared to other surgical interventions. [ABSTRACT FROM AUTHOR]

Introduction: In patients with preoperative atrial fibrillation (AF) undergoing aortic valve replacement, the addition of surgical ablation to surgical aortic valve replacement (SAVR-SA) is efficacious and a Class I guideline. We hypothesized that this subgroup may benefit from SAVR-SA compared to transcatheter aortic valve replacement (TAVR) alone. Methods: Medicare beneficiaries with persistent non-valvular AF who underwent SAVR-SA or TAVR alone between 2012 and 2018 were included. Patients with high-risk surgical comorbidities were excluded. Groups were matched using inverse probability weighting. The primary outcome was all-cause mortality. Secondary outcomes were stroke, transient ischemic attack, permanent pacemaker implantation, bleeding, rehospitalization for atrial arrhythmias, and rehospitalization for heart failure. Kaplan–Meier estimates and Cox proportional-hazards regression were used to compare outcomes. Outcomes were adjusted for variables with a standardized mean difference greater than 0.1. Results: Of 439,492 patients who underwent aortic valve replacement, 2591 underwent SAVR-SA and 1494 underwent TAVR alone. Weighting resulted in adequately matched groups. Compared to TAVR alone, SAVR-SA was associated with a significant reduction in all-cause mortality (HR 0.65, 95% CI 0.53–0.79), permanent pacemaker implantation (HR 0.62, 95% CI 0.44–0.87), bleeding (HR 0.63, 95% CI 0.39–1.00), and rehospitalization for heart failure (HR 0.49 (0.36–0.65). There was no difference in the incidence of stroke (HR 1.07, 95% CI 0.74–1.54), transient ischemic attack (HR 1.05, 95% CI 0.75–1.47), or rehospitalization for atrial arrhythmia. Conclusion: Select patients with persistent non-valvular AF may benefit from SAVR-SA compared to TAVR alone. [ABSTRACT FROM AUTHOR]

Introduction: A significant decrease in emergency presentations of acute cardiac conditions has been observed during the COVID-19 pandemic. We aimed to understand perceptions that influence people's decisions whether to present to the emergency department (ED) with symptoms related to acute cardiovascular events to inform necessary medical communication. Methods: We recruited users of Amazon Mechanical Turk (Seattle, WA) to participate in a survey to elucidate perceptions of COVID-19 risk associated with a visit to the ED. A conjoint analysis was designed based on commonly reported factors associated with people's decisions to present to the ED during the pandemic to calculate preference utilities. Results: After exclusions, 1003 participants completed the survey between 12/5/2020 and 12/6/2020. Participants ranked the perceived risk of contracting COVID-19 at the ED as one of the highest, only second to that at bars and restaurants. Only 68% (685/1003) were willing to present to the ED immediately with severe chest pain. Fear of further transmitting the virus to loved ones was the most frequently cited reason for not presenting. Conjoint analysis demonstrated severe chest pain to be the dominant factor in the decision to present to the ED. Conclusions: The risk of contracting COVID-19 while presenting to the ED for a life-threatening cardiovascular symptom is overestimated and is strongly affected by social factors.
