Relationship between overweight and obesity and cardiac dimensions and function in a paediatric population.

Obesity in adults is associated with left ventricular hypertrophy, dilatation, and myocardial fibrosis, as well as heart failure and coronary heart disease. These associations have been studied to a lesser extent in the paediatric population. This study aims to investigate the relationship between obesity and cardiac structure and function in the paediatric population. In a southern Spanish village, we selected all inhabitants aged 6-17 years stratifying by age, gender, and educational centres. We performed a complete transthoracic echocardiogram evaluating all the cardiac morphological and functional parameters commonly measured in an echocardiographic study. There were 212 children and adolescents included. Of them, 48.1% were males. The mean age was 10.9 ± 3.0 years. A total of 106 (50%) were normal weight, 57 (26.9%) overweight, and 49 (23.1%) obese. Sex and age were similar in all three groups. Overweight and obesity were associated with larger left ventricular end-diastolic and end-systolic volumes (p < 0.0005), greater left ventricular mass (p < 0.0005), and smaller ejection fraction (p < 0.0005). They were also associated with larger atrial, aortic, and right ventricular size. Lateral and mean E/e' ratios were higher (p = 0.007 and p = 0.01 respectively). Body mass index was independently associated with all cavity size variables as well as left ventricular ejection fraction. CONCLUSION: Childhood obesity is independently associated with larger heart chambers, greater left ventricle mass, and smaller left ventricle ejection fraction. WHAT IS KNOWN: • Childhood obesity is related to the development of cardiovascular risk factors and is considered an epidemic of the twenty-first century; its prevalence is rising. WHAT IS NEW: • Childhood overweight and obesity lead to changes in cardiac structure and function which, although not considered clinically pathological, are significant and a result of obesity, and which behave as unfavourable incipient alterations at an early age.

Impact on daily clinical practice of the latest evidence on percutaneous closure of patent foramen ovale after cryptogenic stroke: a single-center experience.

INTRODUCTION AND OBJECTIVES: At the end of 2017, three clinical trials demonstrated that, in selected patients, percutaneous closure of patent foramen ovale (PFO) after cryptogenic stroke (CS) reduces the risk of recurrence. Our aim was to determine the impact of these findings on routine clinical practice in a tertiary hospital. METHODS: Patients with CS and percutaneous closure of PFO during 2001-2020 were included. The clinical characteristics of the patient and the anatomical characteristics of the foramen were analyzed. Based on both, the closure indications were classified into three groups according to the latest European recommendations and were analyzed in two periods, before and after the publication date of the clinical trials. RESULTS: A total of 293 patients were included. The mean age was 49 ± 11 years, and 15% were older than 60 years. The median RoPE score was 6 [p25-75, 5-7] and 75% had complex anatomy (CA). After the publication of the studies, the frequency of CA and the mean age of the patients were significantly higher (89% vs. 69% p < 0.0005 and 51 ± 11 vs. 48 ± 11 years, p = 0.02, respectively), and the RoPE score, significantly lower (5 [5-7] versus 6 [5-7], p = 0.02). Inadequate closure indications were significantly reduced (8% vs. 18%, p = 0.02). CONCLUSION: After the publication of clinical trials that have shown benefit of PFO closure after CS, the number of inappropriate indications for closure has decreased significantly in our institution, with a higher percentage of CA, despite a clinical profile suggestive of lower causal probability of PFO.

CHA2DS2-VASc score as predictor of stroke and all-cause death in stable ischaemic heart disease patients without atrial fibrillation.

BACKGROUND: Cerebrovascular and coronary artery disease share risk factors. The aim was to study CHA2DS2-VASc score as predictor of stroke incidence and death in a sample of patients with sinus rhythm and stable ischemic heart disease (sIHD) during long-term follow-up. METHODS: 1184 patients with sIHD and without atrial fibrillation were included in this single-centre prospective cohort study between February 2000 and January 2004. Stroke and death prediction abilities of CHA2DS2-VASc score in this population were investigated. RESULTS: The median age was 66 (interquartile range (IQR), 60-73 years). The mean follow-up was 11.2 ± 10 years (maximum 17 years). Along this period, 137 patients (11.6% of the sample) suffered a stroke. The mean value of CHA2DS2-VASc score was 3.04 ± 1.36, with CHA2DS2-VASc score ≤ 4 in 85.5% of the sample. Higher CHA2DS2-VASc score at baseline was associated with higher risk of suffering stroke (Hazard Ratio = 1.36, 95% CI 1.20-1.54, p < 0,001) and all-cause death during follow-up (Hazard Ratio = 1.49, 95% CI 1.40-1.58, p < 0,001). CONCLUSIONS: Higher CHA2DS2-VASc score values were associated with higher risk of stroke and all-cause mortality during long-term follow-up in this real-world sample of patients with sIHD in sinus rhythm.

Direct Anticoagulants Versus Vitamin K Antagonists in Patients Aged 80 Years or Older With Atrial Fibrillation in a "Real-world" Nationwide Registry: Insights From the FANTASIIA Study.

OBJECTIVE: To describe major events at follow up in octogenarian patients with atrial fibrillation (AF) according to anticoagulant treatment: direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs). METHODS: A total of 578 anticoagulated patients aged ≥80 years with AF were included in a prospective, observational, multicenter study. Basal features, embolic events (stroke and systemic embolism), severe bleedings, and all-cause mortality at follow up were investigated according to the anticoagulant treatment received. RESULTS: Mean age was 84.0 ± 3.4 years, 56% were women. Direct oral anticoagulants were prescribed to 123 (21.3%) patients. Compared with 455 (78.7%) patients treated with VKAs, those treated with DOACs presented a lower frequency of permanent AF (52.9% vs 61.6%, P = .01), cancer history (4.9% vs 10.9%, P = .046), renal failure (21.1% vs 32.2%, P = .02), and left ventricular dysfunction (2.4% vs 8.0%, P = .03); and higher frequency of previous stroke (26.0% vs 16.6%, P = .02) and previous major bleeding (8.1% vs 3.6%, P = .03). There were no significant differences in Charlson, CHA2DS2VASc, nor HAS-BLED scores. At 3-year follow up, rates of embolic events, severe bleedings, and all-cause death (per 100 patients-year) were similar in both groups (DOACs vs VKAs): 0.34 vs 1.35 (P = .15), 3.45 vs 4.41 (P = .48), and 8.2 vs 11.0 (P = .18), respectively, without significant differences after multivariate analysis (hazard ratio [HR]: 0.25, 95% confidence interval [CI]: 0.03-1.93, P = .19; HR: 0.88, 95% CI: 0.44-1.76, P = .72 and HR: 0.84, 95% CI: 0.53-1.33, P = .46, respectively). CONCLUSION: In this "real-world" registry, the differences in major events rates in octogenarians with AF were not statistically significant in those treated with DOACs versus VKAs.

Comparison of 1-Year Outcome in Patients With Severe Aorta Stenosis Treated Conservatively or by Aortic Valve Replacement or by Percutaneous Transcatheter Aortic Valve Implantation (Data from a Multicenter Spanish Registry).

The factors that influence decision making in severe aortic stenosis (AS) are unknown. Our aim was to assess, in patients with severe AS, the determinants of management and prognosis in a multicenter registry that enrolled all consecutive adults with severe AS during a 1-month period. One-year follow-up was obtained in all patients and included vital status and aortic valve intervention (aortic valve replacement [AVR] and transcatheter aortic valve implantation [TAVI]). A total of 726 patients were included, mean age was 77.3 ± 10.6 years, and 377 were women (51.8%). The most common management was conservative therapy in 468 (64.5%) followed by AVR in 199 (27.4%) and TAVI in 59 (8.1%). The strongest association with aortic valve intervention was patient management in a tertiary hospital with cardiac surgery (odds ratio 2.7, 95% confidence interval 1.8 to 4.1, p <0.001). The 2 main reasons to choose conservative management were the absence of significant symptoms (136% to 29.1%) and the presence of co-morbidity (128% to 27.4%). During 1-year follow-up, 132 patients died (18.2%). The main causes of death were heart failure (60% to 45.5%) and noncardiac diseases (46% to 34.9%). One-year survival for patients treated conservatively, with TAVI, and with AVR was 76.3%, 94.9%, and 92.5%, respectively, p <0.001. One-year survival of patients treated conservatively in the absence of significant symptoms was 97.1%. In conclusion, most patients with severe AS are treated conservatively. The outcome in asymptomatic patients managed conservatively was acceptable. Management in tertiary hospitals is associated with valve intervention. One-year survival was similar with both interventional strategies.

Prognostic impact of baseline low blood pressure in hypertensive patients with stable coronary artery disease of daily clinical practice.

The authors' aim was to investigate the prognostic value of first-visit systolic and diastolic blood pressure (SBP/DBP) in hypertensive patients with stable coronary artery disease (sCAD) in conditions of contemporary daily clinical practice. From February 1, 2000, to January 31, 2004, 690 consecutive hypertensive patients with sCAD (mean age 68 ± 10 years, 65% male) were prospectively followed in the outpatient cardiology clinic for major events (acute coronary syndrome, revascularization, stroke, heart failure, or death) and associations with baseline SBP/DBP were investigated. At first visit, median SBP/SDP were 130/75 mm Hg (interquartile range, 25-75; 120-140/70-80 mm Hg). After 25 months of follow-up (median), 19 patients died (2.8%); 10 from cardiovascular causes (1.5%), 87 patients experienced a coronary event (13%), and 130 patients (19%) a major event. After adjusting for baseline variables, DBP <75 mm Hg or SBP <130 mm Hg resulted in independent predictors of major events (hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.07-2.16, P=.02; HR, 1.68; 95% CI, 1.18-2.40, P=.004, respectively), coronary events (HR, 1.78; 95% CI, 1.15-2.75, P=.009; HR, 1.84; 95% CI, 1.20-2.83, P=.005, respectively), and cardiovascular mortality (HR, 7.02; 95% CI, 1.26-39.04, P=.03; HR, 9.26; 95% CI, 1.33-64.32, P=.02, respectively). In this study, a low first-visit SBP or DBP was associated with an adverse prognosis in hypertensive patients with sCAD of contemporary daily clinical practice.

Usefulness of transesophageal echocardiography during implantation of the CoreValve percutaneous aortic prosthesis: influence of the learning curve.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the usefulness of transesophageal echocardiography during the implantation of the CoreValve percutaneous aortic prosthesis and the influence of the learning curve in its indications. METHODS: From April 2008 to January 2010, 53 patients were treated for symptomatic severe aortic stenosis with a CoreValve percutaneous aortic prosthesis. Transesophageal echocardiography was performed during the procedure for two reasons: if a discrepancy between the measures of the aortic annulus arose before the implantation and to provide visualization if a complication occurred during the procedure. Patients were divided in to two groups based on the learning curve (group I:the first 25 patients, group II: all of the subsequent patients). RESULTS: Thirty-six transesophageal echocardiographies were performed on 28 patients (53%).In 15 cases the indication was to assist us in determining the proper sized prosthesis, and in the other 21 cases it was performed due to a complication during the procedure. The numbers of intraprocedure transesophageal echocardiographies were similar in both learning-curve groups, (64% in group I vs. 71% in group II, P = 0.56) but the proportion of the studies indicated by serious complications was significantly lower in the second period of the learning curve (67% in group I vs. 17% in group II, P < 0.05). CONCLUSIONS: In our experience, transesophageal echocardiography was very useful in more than one-half of the patients during the implantation of the CoreValve percutaneous aortic prosthesis. After overcoming the learning curve, its indication due to serious procedure-related complications decreased significantly.

Etiologic spectrum and clinical features of mitral regurgitation in a Spanish population.

BACKGROUND AND AIM OF THE STUDY: The study aim was to investigate the etiologic spectrum of at least moderate mitral regurgitation (MR) in patients at a tertiary care center in a Spanish region. METHODS: All patients referred for echocardiography with moderate or severe MR, assessed according to the guidelines of the American Society of Echocardiography, were included prospectively in the study. RESULTS: Between October 2006 and February 2008, a total of 276 patients (157 females, 119 males; mean age 61 +/- 20 years) were enrolled into the study. At the time of evaluation, 67% of the patients were outpatients and the remainder were hospitalized. The NYHA functional class was III-IV in 31% of patients. The main echocardiographic data were: color flow jet area 11 +/- 5 cm2, vena contracta 6.7 +/- 1.9 mm, effective regurgitant orifice area 0.46 +/- 0.28 cm2, left ventricular diastolic and systolic diameters 58 +/- 10 mm and 39 +/- 12 mm, respectively, left ventricular ejection fraction 0.55 +/- 0.19, and pulmonary artery systolic pressure 39 +/- 16 mmHg. The MR was degenerative in 42% of patients, rheumatic in 22%, functional due to idiopathic dilated cardiomyopathy in 18%, functional due to ischemic cardiomyopathy in 7%, congenital in 7%, and had other causes in 4%. CONCLUSION: Among this Spanish population, the majority of the moderate or severe MR encountered was organic, with degenerative mitral disease as the most common etiology. Functional regurgitation was present in a significant proportion of patients, with idiopathic dilated cardiomyopathy being the most frequent cause.

Three-dimensional echocardiography-guided repair of residual shunt after percutaneous atrial septal defect closure.

A 28-year-old woman was referred to closure of a residual shunt produced through a percutaneous device previously implanted in the atrial septum. The imaging protocol to guide the procedure included 2D TEE and real time 3D (RT3D) transesophageal echocardiography (TEE) imaging. RT3D TEE facilitated the evaluation of the defect morphology, and the relationship with the previous device, allowing a proper understanding of the mechanism responsible for the residual shunt. It was also a useful tool for guiding device deployment, providing clear intraprocedural information about catheter position and the spatial relationship with the previous device. In conclusion, RT3D TEE and 2D TEE are complementary techniques for the evaluation and guidance of transcatheter closure of complex atrial septal defects.

Large Mass in Left Atrium by Transesophageal Echocardiography: An Unusual Case of Cardiac Angiosarcoma Mimicking a Cystic Mass.

Primary cardiac tumors are extremely rare. Among them, malignant tumors constitute approximately 15% of primary cardiac tumors. Angiosarcomas are the most frequent. They often appear as mural masses in the right atrium and completely replace the atrial wall and fill the entire cardiac chamber. We report an unusual case of angiosarcoma in a 75-year-old woman with a cystic appearance, located in the left atrium and causing critical mitral stenosis. (Echocardiography, ****;**:E1-E2).
