Infective endocarditis in adult patients with congenital heart disease

Background: Congenital Heart Disease (CHD) predisposes to Infective Endocarditis (IE), but data about characterization and prognosis of IE in CHD patients is scarce. Methods: The ESC-EORP-EURO-ENDO study is a prospective international study in IE patients (n = 3111). In this pre-specified analysis, adult CHD patients (n = 365, 11.7%) are described and compared with patients without CHD (n = 2746) in terms of baseline characteristics and mortality. Results: CHD patients (73% men, age 44.8 ± 16.6 years) were younger and had fewer comorbidities. Of the CHD patients, 14% had a dental procedure before hospitalization versus 7% in non-CHD patients (p < 0.001) and more often had positive blood cultures for Streptococcus viridans (16.4% vs 8.8%, p < 0.001). As in non-CHD patients, IE most often affected the left-sided valves. For CHD patients, in-hospital mortality was 9.0% vs 18.1% in non-CHD patients (p < 0.001), and also, during the entire follow-up of 700 days, survival was more favorable (log-rank p < 0.0001), even after adjustment for age, gender and major comorbidities (Hazard Ratio (HR) 0.68; 95%CI 0.50–0.92). Within the CHD population, multivariable Cox regression revealed the following effects (HR and [95% CI]) on mortality: fistula (HR 6.97 [3.36–14.47]), cerebral embolus (HR 4.64 [2.08–10.35]), renal insufficiency (HR 3.44 [1.48–8.02]), Staphylococcus aureus as causative agent (HR 2.06 [1.11–3.81]) and failure to undertake surgery when indicated (HR 5.93 [3.15–11.18]). Conclusions: CHD patients with IE have a better outcome in terms of all-cause mortality. The observed high incidence of dental procedures prior to IE warrants further studies about the current use, need and efficacy of antibiotic prophylaxis in CHD patients

Multicentric Atrial Strain COmparison between Two Different Modalities: MASCOT HIT Study

Two methods are currently available for left atrial (LA) strain measurement by speckle tracking echocardiography, with two different reference timings for starting the analysis: QRS (QRS-LASr) and P wave (P-LASr). The aim of MASCOT HIT study was to define which of the two was more reproducible, more feasible, and less time consuming. In 26 expert centers, LA strain was analyzed by two different echocardiographers (young vs senior) in a blinded fashion. The study population included: healthy subjects, patients with arterial hypertension or aortic stenosis (LA pressure overload, group 2) and patients with mitral regurgitation or heart failure (LA volume–pressure overload, group 3). Difference between the inter-correlation coefficient (ICC) by the two echocardiographers using the two techniques, feasibility and analysis time of both methods were analyzed. A total of 938 subjects were included: 309 controls, 333 patients in group 2, and 296 patients in group 3. The ICC was comparable between QRS-LASr (0.93) and P-LASr (0.90). The young echocardiographers calculated QRS-LASr in 90% of cases, the expert ones in 95%. The feasibility of P-LASr was 85% by young echocardiographers and 88% by senior ones. QRS-LASr young median time was 110 s (interquartile range, IR, 78-149) vs senior 110 s (IR 78-155); for P-LASr, 120 s (IR 80-165) and 120 s (IR 90-161), respectively. LA strain was feasible in the majority of patients with similar reproducibility for both methods. QRS complex guaranteed a slightly higher feasibility and a lower time wasting compared to the use of P wave as the reference

Global and regional myocardial function and outcomes after transcatheter aortic valve implantation for aortic stenosis and preserved ejection fraction.

AIM: To investigate the effects of transcatheter aortic valve implantation (TAVI) on early recovery of global and segmental myocardial function in patients with severe symptomatic aortic stenosis and preserved left ventricular ejection fraction (LVEF) and to determine if parameters of deformation correlate with outcomes. METHODS: The echocardiographic (strain analysis) and outcome (hospitalizations because of heart failure and mortality) data of 62 consecutive patients with preserved LVEF (64.54 ± 7.97%) who underwent CoreValve prosthesis implantation were examined. RESULTS: Early after TAVI (5 ± 3.9 days), no significant changes in LVEF or diastolic function were found, while a significant drop of systolic pulmonary artery pressure (PAP) occurred (42.3 ± 14.9 vs. 38.1 ± 13.9 mmHg, P = 0.028). After TAVI global longitudinal strain (GLS) did not change significantly, whereas significant improvement in global mid-level left ventricular (LV) radial strain (GRS) was found (-16.71 ± 2.42 vs. -17.32 ± 3.25%; P = 0.33; 16.57 ± 6.6 vs. 19.48 ± 5.97%, P = 0.018, respectively). Early significant recovery of longitudinal strain was found in basal lateral and anteroseptal segments (P = 0.038 and 0.048). Regional radial strain at the level of papillary muscles [P = 0.038 mid-lateral, P < 0.001 mid-anteroseptum (RSAS)] also improved. There was a significant LV mass index reduction in the late follow-up (152.42 ± 53.21 vs. 136.24 ± 56.67 g/m, P = 0.04). Mean follow-up period was 3.5 ± 1.9 years. Parameters associated with worse outcomes in univariable analysis were RSAS pre-TAVI, LV end-diastolic diameter after TAVI, relative wall thickness, and mitral E and E/A after TAVI. CONCLUSION: Global and regional indices of myocardial function improved early after TAVI, suggesting the potential of myocardium to recover with a reduced risk for clinical deterioration

Left atrial strain determinants and clinical features according to the heart failure stages. New insight from EACVI MASCOT registry

International audienceFew studies analyzed left atrial (LA) peak atrial longitudinal strain (PALS) determinants, particularly across heart failure (HF) stages. We aimed to analyze the pathophysiological and clinical PALS correlates in a large multicentric prospective study. This is a multicenter prospective observational study enrolling 745 patients with HF stages. Data included PALS and left ventricular global longitudinal strain (LV-GLS). Exclusion criteria were: valvular prosthesis; atrial fibrillation; cardiac transplantation; poor acoustic window. Median global PALS was 17% [24-32]. 29% of patients were in HF-stage 0/A, 35% in stage-B, and 36% in stage-C. Together with age, the echocardiographic determinants of PALS were LA volume and LV-GLS (overall model R(2) = 0.50, p &lt; 0.0001). LV-GLS had the strongest association with PALS at multivariable analysis (beta: -3.60 ± 0.20, p &lt; 0.0001). Among HF stages, LV-GLS remained the most important PALS predictor (p &lt; 0.0001) whereas age was only associated with PALS in lower HF-stage 0/A or B (R = - 0.26 p &lt; 0.0001, R = - 0.23 p = 0.0001). LA volume increased its association to PALS moving from stage 0/A (R = - 0.11; P = 0.1) to C (R = - 0.42; P &lt; 0.0001). PALS was the single most potent echocardiographic parameter in predicting the HF stage (AUC for B vs. 0/A 0.81, and AUC vs. 0/A for C 0.76). PALS remained independently associated with HF stages after adjusting for ejection fraction, E/e’ ratio, and mitral regurgitation grade (p &lt; 0.0001). Although influenced by LV-GLS and LA size across HF stages, PALS is incrementally and independently associated with clinical status. LA function may reflect a substantial part of the hemodynamic consequences of ventricular dysfunction

Prognostic Value of Preprocedural LV Global Longitudinal Strain for Post-TAVR-Related Morbidity and Mortality: A Meta-Analysis

BACKGROUND: Left ventricular ejection fraction (LVEF) demonstrates limited prognostic value for post-transcatheter aortic valve replacement (TAVR) outcomes. Evidence regarding the potential role of left ventricular global longitudinal strain (LV-GLS) in this setting is inconsistent. OBJECTIVES: The aim of this systematic review and meta-analysis of aggregated data was to evaluate the prognostic value of preprocedural LV-GLS for post-TAVR-related morbidity and mortality. METHODS: The authors searched PubMed, Embase, and Web of Science for studies investigating the association between preprocedural 2-dimensional speckle-tracking-derived LV-GLS and post-TAVR clinical outcomes. An inversely weighted random effects meta-analysis was adopted to investigate the association between LV-GLS vs primary (ie, all-cause mortality) and secondary (ie, major cardiovascular events [MACE]) post-TAVR outcomes. RESULTS: Of the 1,130 identified records, 12 were eligible, all of which had a low-to-moderate risk of bias (Newcastle-Ottawa scale). On average, 2,049 patients demonstrated preserved LVEF (52.6% ± 1.7%), but impaired LV-GLS (-13.6% ± 0.6%). Patients with a lower LV-GLS had a higher all-cause mortality (pooled HR: 2.01; 95% CI: 1.59-2.55) and MACE (pooled odds ratio [OR]: 1.26; 95% CI: 1.08-1.47) risk compared with patients with higher LV-GLS. In addition, each percentage point decrease of LV-GLS (ie, toward 0%) was associated with an increased mortality (HR: 1.06; 95% CI: 1.04-1.08) and MACE risk (OR: 1.08; 95% CI: 1.01-1.15). CONCLUSIONS: Preprocedural LV-GLS was significantly associated with post-TAVR morbidity and mortality. This suggests a potential clinically important role of pre-TAVR evaluation of LV-GLS for risk stratification of patients with severe aortic stenosis.

Predictors of embolism and death in left-sided infective endocarditis: the European Society of Cardiology EURObservational Research Programme European Infective Endocarditis registry

International audienceBackground and Aims Even though vegetation size in infective endocarditis (IE) has been associated with embolic events (EEs) and mortality risk, it is unclear whether vegetation size associated with these potential outcomes is different in left-sided IE (LSIE). This study aimed to seek assessing the vegetation cut-off size as predictor of EE or 30-day mortality for LSIE and to determine risk predictors of these outcomes. Methods The European Society of Cardiology EURObservational Research Programme European Infective Endocarditis is a prospective, multicentre registry including patients with definite or possible IE throughout 2016–18. Cox multivariable logistic regression analysis was performed to assess variables associated with EE or 30-day mortality. Results There were 2171 patients with LSIE (women 31.5%). Among these affected patients, 459 (21.1%) had a new EE or died in 30 days. The cut-off value of vegetation size for predicting EEs or 30-day mortality was &gt;10 mm [hazard ratio (HR) 1.38, 95% confidence interval (CI) 1.13–1.69, P = .0015]. Other adjusted predictors of risk of EE or death were as follows: EE on admission (HR 1.89, 95% CI 1.54–2.33, P &lt; .0001), history of heart failure (HR 1.53, 95% CI 1.21–1.93, P = .0004), creatinine &gt;2 mg/dL (HR 1.59, 95% CI 1.25–2.03, P = .0002), Staphylococcus aureus (HR 1.36, 95% CI 1.08–1.70, P = .008), congestive heart failure (HR 1.40, 95% CI 1.12–1.75, P = .003), presence of haemorrhagic stroke (HR 4.57, 95% CI 3.08–6.79, P &lt; .0001), alcohol abuse (HR 1.45, 95% CI 1.04–2.03, P = .03), presence of cardiogenic shock (HR 2.07, 95% CI 1.29–3.34, P = .003), and not performing left surgery (HR 1.30 95% CI 1.05–1.61, P = .016) (C-statistic = .68). Conclusions Prognosis after LSIE is determined by multiple factors, including vegetation size
