A Confounder in the Study of a Patient With Infective Endocarditis.

Positron emission tomography (18FDG PET-CT) is a widely used method to help in the diagnosis of infective endocarditis (IE). Lipomatous hypertrophy of the interatrial septum (LHIS) is an uncommon fat deposition in the region of the interatrial septum. PET-CT images of LHIS may be indistinguishable from changes associated with IE.

Percutaneous mitral valve repair in patients developing severe mitral regurgitation early after an acute myocardial infarction: A review.

Acute mitral regurgitation (MR) may develop in the setting of an acute myocardial infarction (AMI) because of papillary muscle dysfunction or rupture. Severe acute MR in this scenario is a life-threatening complication associated with hemodynamic instability and pulmonary edema, and has been linked to a worse prognosis even after reperfusion. Patients treated solely with medical therapy have the highest mortality rates. Surgery has been the only treatment strategy until recently, but the results of the technique are hindered by high rates of morbidity and mortality. Therefore, the development of less invasive interventions for correcting MR would be ideal. We aimed to review the current role of transcatheter interventions in this clinical setting.

Outcomes of culture-negative vs. culture-positive infective endocarditis: the ESC-EORP EURO-ENDO registry.

AIM: Fatality of infective endocarditis (IE) is high worldwide, and its diagnosis remains a challenge. The objective of the present study was to compare the clinical characteristics and outcomes of patients with culture-positive (CPIE) vs. culture-negative IE (CNIE). METHODS AND RESULTS: This was an ancillary analysis of the ESC-EORP EURO-ENDO registry. Overall, 3113 patients who were diagnosed with IE during the study period were included in the present study. Of these, 2590 (83.2%) had CPIE, whereas 523 (16.8%) had CNIE. As many as 1488 (48.1%) patients underwent cardiac surgery during the index hospitalization, 1259 (48.8%) with CPIE and 229 (44.5%) with CNIE. The CNIE was a predictor of 1-year mortality [hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.04-1.56], whereas surgery was significantly associated with survival (HR 0.49, 95% CI 0.41-0.58). The 1-year mortality was significantly higher in CNIE than CPIE patients in the medical subgroup, but it was not significantly different in CNIE vs. CPIE patients who underwent surgery. CONCLUSION: The present analysis of the EURO-ENDO registry confirms a higher long-term mortality in patients with CNIE compared with patients with CPIE. This difference was present in patients receiving medical therapy alone and not in those who underwent surgery, with surgery being associated with reduced mortality. Additional efforts are required both to improve the aetiological diagnosis of IE and identify CNIE cases early before progressive disease potentially contraindicates surgery.

Spanish Registry of Acute Aortic Syndrome (RESA). Changes in therapeutic management and lower mortality in acute aortic syndrome.

INTRODUCTION AND OBJECTIVES: The Spanish Registry of Acute Aortic Syndrome (RESA) was launched in 2005 to identify the characteristics of acute aortic syndrome (AAS) in Spain. The aim of this study was to analyze the differences in management and mortality in the 3 RESA iterations. METHODS: We analyzed data from patients with AAS prospectively included by 24 to 30 tertiary centers during the 3 iterations of the registry: RESA I (2005-2006), RESA-II (2012-2013), and RESA III (2018-2019). RESULTS: AAS was diagnosed in 1902 patients (74% men; age, 60.7±12.5 years): 1329 (69.9%) type A and 573 (30.1%) type B. Comparison of the 3 periods revealed that the use of computed tomography increased as the first diagnostic technique (77.1%, 77.9%, and 84.2%, respectively; P=.001). In type A, surgical management increased (79.6%, 78.7%, and 84.5%; P=.045) and overall mortality decreased (41.2%, 34.5%, and 31.2%; P=.002), due to a reduction in surgical mortality (33.4%, 25.1%, and 23.9%; P=.003). In type B, endovascular treatment increased (22.8%, 32.8%, and 38.7%; P=.006), while medical and surgical treatment decreased. Overall type B mortality also decreased (21.6%, 16.1%, and 12.0%; P=.005) in line with a reduction in mortality with medical (16.8%, 13.8%, and 8.8%, P=.030) and endovascular (27.0%, 18.0%, and 9.2%; P=.009) treatments. CONCLUSIONS: The iterations of RESA show a decrease in mortality from type A AAS, coinciding with an increase in surgical treatment and a reduction in surgical mortality. In type B, the use of endovascular treatment was associated with improved survival, allowing better management in patients with complications.

Value of non-apical echocardiographic views in the up-grading of patients with aortic stenosis.

Purpose. Echocardiography assessment from apical five-chamber view (A5CV) is the standard technique for aortic stenosis (AS) grading. Data on non-apical views, such as right parasternal (RPV), subcostal (SCV) and suprasternal notch (SSNV), is scarce and constitutes the aim of our study. Methods. We designed an observational study that included patients with AS recruited prospectively in whom the stenosis was graded by echocardiography from A5CV and non-apical view. The value of non-apical views in up-grading the stenosis severity (primary objective), the prognostic relevance of such reclassification and the feasibility and reproducibility of non-apical views assessment (secondary objectives) was evaluated. Results. Feasibility of AS appraisal from RPV, SCV and SSNV was 78%, 81% and 56%, respectively (SCV vs SSNV, p = .009). AS were up-graded from non-apical views according to peak gradient, mean gradient, area and indexed area by 24%, 17%, 24% and 22%, respectively (p < .0001). Non-apical views reclassified from non-severe to severe AS, from low gradient severe to high gradient severe AS and from non-critical to critical AS 19%, 23% and 3% of cases (p < .0001). The 4-years hard cardiac events rate was 41% in patients with non-severe AS, 67% in patients with severe AS from non-apical views, 68% in patients with severe AS from A5CV and 80% in patients with severe AS from A5CV and non-apical views (p < .001). Reproducibility of AS evaluation from non-apical views was fair to excellent (intraclass correlation coefficients: SSNV = 0.44, RPV = 0.61, SCV = 0.92). Conclusion. Assessment of AS from non-apical views is feasible, reproducible and valuable over A5CV; its use is encouraged.

A biomechanical model of the pathological aortic valve: simulation of aortic stenosis.

Aortic stenosis (AS) disease is a narrowing of the aortic valve (AV) opening which reduces blood flow from the heart causing several health complications. Although a lot of work has been done in AV simulations, most of the efforts have been conducted regarding healthy valves. In this article, a new three-dimensional patient-specific biomechanical model of the valve, based on a parametric formulation of the stenosis that permits the simulation of different degrees of pathology, is presented. The formulation is based on a double approach: the first one is done from the geometric point of view, reducing the effective ejection area of the AV by joining leaflets using a zipper effect to sew them; the second one, in terms of functionality, is based on the modification of AV tissue properties due to the effect of calcifications. Both healthy and stenotic valves were created using patient-specific data and results of the numerical simulation of the valve function are provided. Analysis of the results shows a variation in the first principal stress, geometric orifice area, and blood velocity which were validated against clinical data. Thus, the possibility to create a pipeline which allows the integration of patient-specific data from echocardiographic images and iFR studies to perform finite elements analysis is proved.

Impact of different models of improvement of continuity of care on lipid control and the delay of visits to cardiology.

Aims: To analyze the impact of implementing three different models of continuity of care on the delay of first visits to the cardiologist (management end point) and on LDL-cholesterol control rates among patients with atherosclerotic vascular disease (clinical end point). Methods: Observational, longitudinal and retrospective study of patients with cardiovascular disease and LDL-cholesterol ≥70 mg/dl attended in three hospitals (H1/H2/H3). In H1 and H2, a virtual system (telecardiology) was developed (in H1, internal audits and specific medical education were also performed). In H3 a cardiologist was integrated into the primary care center. Results: The delay of visits to cardiologist significantly improved from 66.5 ± 29.1 days to 34.1 ± 14.1 days (p < 0.001), as well as the intensification of lipid-lowering treatment and the achievement of lipid goals. LDL-cholesterol control rates were higher in H1 and the reduction of the delay of visits in H3. Conclusion: Continuity of care is associated with improvements in management and clinical end points.
