Abstract

Background: Patients with chest pain represent a large portion of emergency department (ED) presentations around the world. Accurate risk assessment to rule out acute coronary syndrome (ACS) is required. Aim: To measure accuracy and characteristics of ED doctors and nurses when assessing patients for suspected ACS and the associations with outcome. Methods: A sub-analysis of a large randomised trial that compared high-sensitivity troponin to conventional troponin was carried out. Both nurses and doctors conducted ACS risk assessments on 1857 patients and concordance comparisons were undertaken. Findings: There was no difference between the accuracy of ED nurses and doctors (c-statistic: 0.67 vs 0.68 respectively; P=0.35). Both clinician types made similar ACS risk assessments. Nurses with specialist qualifications and consultant doctors were the most accurate, at 65.4% and 74.2%, respectively. Conclusion: Nurses and doctors in the ED made similar ACS risk assessments but both were sub-optimal. Standard clinical pathways to assist ED doctors and nurses improve their ACS impression accuracy could be beneficial. [ABSTRACT FROM AUTHOR]

Abstract

Background: Transcatheter heart valve (THV) dysfunction with an elevated gradient or paravalvular leak (PVL) may be documented late after THV implantation. Medical management, paravalvular plugs, redo THV replacement, or surgical valve replacement may be considered. However, late balloon dilatation is rarely utilized because of concerns about safety or lack of efficacy.Objectives: We aimed to evaluate the safety and efficacy of late dilatation in the management of THV dysfunction.Methods: All patients who underwent late dilatation for symptomatic THV dysfunction at 2 institutions between 2016 and 2021 were identified. Baseline, procedural characteristics, and clinical and echocardiographic outcomes were documented. THV frame expansion was assessed by multislice computed tomography before and after late dilatation.Results: Late dilatation was performed in 30 patients a median of 4.6 months (IQR: 2.3-11.0 months) after THV implantation in the aortic (n = 25; 83.3%), mitral (n = 2; 6.7%), tricuspid (n = 2; 6.7%) and pulmonary (n = 1; 3.3%) position. THV underexpansion was documented at baseline, and frame expansion substantially improved after late dilatation. The mean transvalvular gradient fell in all patients. For aortic THVs specifically, mean transaortic gradient fell from 25.4 ± 13.9 mm Hg to 10.8 ± 4.1 mm Hg; P < 0.001. PVL was reduced to ≤mild in all 11 patients with a previous >mild PVL. Embolic events, stroke, annular injury, and bioprosthetic leaflet injury were not observed. Symptomatic benefit was durable at 19.6 months (IQR: 14.8-36.1 months) follow-up.Conclusions: Balloon dilatation late after THV implantation appears feasible and safe in appropriately selected patients and may result in THV frame expansion resulting in improvements in hemodynamic performance and PVL.
