BACKGROUND:Severe tricuspid regurgitation is associated with disabling symptoms and an increased risk of death. Data regarding outcomes after percutaneous transcatheter tricuspid-valve replacement are needed. METHODS:In this international, multicenter trial, we randomly assigned 400 patients with severe symptomatic tricuspid regurgitation in a 2:1 ratio to undergo either transcatheter tricuspid-valve replacement and medical therapy (valve-replacement group) or medical therapy alone (control group). The hierarchical composite primary outcome was death from any cause, implantation of a right ventricular assist device or heart transplantation, postindex tricuspid-valve intervention, hospitalization for heart failure, an improvement of at least 10 points in the score on the Kansas City Cardiomyopathy Questionnaire overall summary (KCCQ-OS), an improvement of at least one New York Heart Association (NYHA) functional class, and an improvement of at least 30 m on the 6-minute walk distance. A win ratio was calculated for the primary outcome by comparing all possible patient pairs, starting with the first event in the hierarchy. RESULTS:A total of 267 patients were assigned to the valve-replacement group and 133 to the control group. At 1 year, the win ratio favoring valve replacement was 2.02 (95% confidence interval [CI], 1.56 to 2.62; P<0.001). In comparisons of patient pairs, those in the valve-replacement group had more wins than the control group with respect to death from any cause (14.8% vs. 12.5%), postindex tricuspid-valve intervention (3.2% vs. 0.6%), and improvement in the KCCQ-OS score (23.1% vs. 6.0%), NYHA class (10.2% vs. 0.8%), and 6-minute walk distance (1.1% vs. 0.9%). The valve-replacement group had fewer wins than the control group with respect to the annualized rate of hospitalization for heart failure (9.7% vs. 10.0%). Severe bleeding occurred in 15.4% of the valve-replacement group and in 5.3% of the control group (P = 0.003); new permanent pacemakers were implanted in 17.4% and 2.3%, respectively (P<0.001). CONCLUSIONS:For patients with severe tricuspid regurgitation, transcatheter tricuspid-valve replacement was superior to medical therapy alone for the primary composite outcome, driven primarily by improvements in symptoms and quality of life.

BACKGROUND/UNASSIGNED:Stenting of bifurcation and non-aorto-ostial coronary lesions presents significant challenges due to geographic miss and restenosis. Drug-coated balloons (DCBs) offer an attractive alternative to drug-eluting stents in the treatment of these lesions. METHODS/UNASSIGNED:We conducted a systematic review of studies published from 2001 to 2024 comparing DCBs with plain old balloon angioplasty and/or drug-eluting stents (DES) in de novo coronary bifurcation lesions and non-aorto-ostial (NAO) lesions. A meta-analysis was performed with target lesion failure (TLF) as the selected outcome, defined as a composite of target lesion revascularization, target vessel myocardial infarction, or cardiovascular death. RESULTS/UNASSIGNED:= .0015), respectively. CONCLUSIONS/UNASSIGNED:In our meta-analysis, DCBs were associated with a lower rate of TLF compared with plain old balloon angioplasty and DES. These findings suggest that DCBs could be preferred for the treatment of bifurcation and NAO lesions.

Wearables yield a wide array of sleep-related measures that are relevant to Long COVID. We leveraged wearables-derived sleep measures (WDSM) to identify differences between individuals with Long COVID (LC) versus individuals with possible or no LC in the RECOVER adult cohort. We found significant associations between LC and reduced heart rate variability measured during sleep and increased nightly variability in sleep duration after adjusting for confounders. Moreover, LC was independently associated with lower sleep efficiency, greater variability of nighttime sleep timing, higher resting heart rate, lower respiratory rate during rapid eye movement (REM) sleep, prolonged REM sleep onset latency, worse global physical and mental health. Cluster analysis identified distinct multidimensional patterns of WDSM that are associated with LC and quality of life. Together, the strong association between WDSM, or WDSM clusters, with LC provides a potential biomarker for future validation efforts to detect LC and monitor treatment effectiveness.

Stereotactic body radiotherapy (SBRT) for prostate cancer is a generally well-tolerated treatment but can rarely lead to complications such as fistula formation. We report a 69-year-old male on maintenance ibrutinib for chronic lymphocytic leukemia who developed a fistula between his bladder and vas deferens in the setting of ascending scrotal infection. Despite his prior history of SBRT, the fistula was successfully treated with minimally invasive measures. A combination of abscess debridement, urinary diversion, and broad-spectrum antibiotics helped to achieve fistula resolution. The unique presentation described herein highlights the importance of early aggressive intervention for source control and infection management in patients with complex pelvic infections post-SBRT.

BACKGROUND:The COVID-19 pandemic had a significant impact on healthcare delivery. Older adults with multimorbidities were at risk of healthcare disruptions for the management of their chronic conditions. OBJECTIVE:To characterize healthcare disruptions during the COVID-19 healthcare shutdown and recovery period (March 7, 2020-October 6, 2020) and their effects on disease management among older adults with multimorbidities who were patients of NYC Health + Hospitals (H + H), the largest municipal safety-net system in the United States. DESIGN/METHODS:Observational. PATIENTS/METHODS:Patients aged 50 + with hypertension or diabetes and at least one other comorbidity, at least one H + H ambulatory visit in the six months before COVID-19 pandemic onset (March 6, 2020), and at least one visit in the post-acute shutdown period (October 7, 2020 to December 31, 2023). MAIN MEASURES/METHODS:We characterized disruption in care (defined as no ambulatory or telehealth visits during the acute shutdown) and estimated the effect of disruption on blood pressure control, hemoglobin A1c (HbA1c), and low-density lipoprotein (LDL) cholesterol using difference-in-differences models. KEY RESULTS/RESULTS:Out of 73,889 individuals in the study population, 12.5% (n = 9,202) received no ambulatory or telehealth care at H + H during the acute shutdown. Low pre-pandemic healthcare utilization, Medicaid insurance, and self-pay were independent predictors of care disruption. In adjusted analyses, the disruption group had a 3.0-percentage point (95% CI: 1.2-4.8) greater decrease in blood pressure control compared to those who received care. Disruption did not have a significant impact on mean HbA1c or LDL. CONCLUSIONS:Care disruption was associated with declines in blood pressure control, which while clinically modest, could impact risk of cardiovascular outcomes if sustained. Disruption did not affect HbA1c or LDL. Telehealth mitigated impacts of the pandemic on care disruption and subsequent disease management. Targeted outreach to those at risk of care disruption is needed during future crises.

BACKGROUND AND AIMS/OBJECTIVE:Endoscopic submucosal dissection (ESD) is preferred over endoscopic mucosal resection (EMR) for resection of colon cancer with suspected superficial invasion. Data on appropriate utilization of ESD such as rates of cancer and non-curative resection (NCR) are under-reported. METHODS:Retrospective multicenter study of 547 consecutive colonic lesions undergoing ESD was performed. Outcomes were rates of cancer, NCR, surgery and predictors of NCR. RESULTS:Of all lesions, histopathology demonstrated cancer in 12% (n = 66). Overall, NCR was seen in 59.1% (n = 39) patients and 24.6% (n = 135) lesions contained high-grade dysplasia. For NCR, patients underwent surgery in 7.6% (n = 3) and adverse events were observed in 8.8% (n = 48). CONCLUSIONS:In our large multicenter Western cohort, the pathology was found to be benign in most of the colon ESDs and there was high NCR for resected lesions with cancer. The overall surgery rate, however, remained low. This study highlights the need to refine lesion selection criteria while continuing to optimize ESD technique to match the efficiency and safety of EMR.
