BACKGROUND: Despite anticoagulation therapy, ischemic stroke risk in atrial fibrillation (AF) remains substantial. We hypothesize that left atrial enlargement (LAE) is more prevalent in AF patients admitted with ischemic stroke who are therapeutic, as opposed to nontherapeutic, on anticoagulation. METHODS: We included consecutive patients with AF admitted with ischemic stroke between April 1, 2015, and December 31, 2016. Patients were divided into two groups based on whether they were therapeutic (warfarin with an international normalized ratio ≥ 2...

A 50-year-old man with a murmur since birth developed systemic arterial hypertension as an adult. He came to the hospital because of dyspnea. He had a pulmonic valve ejection click and a murmur of pulmonic stenosis. His echocardiogram showed biventricular hypertrophy, a flat ventricular septum, a D-shaped left ventricle, systolic doming of the pulmonic valve, and Doppler evidence of a 70 mm Hg peak systolic pressure gradient across the pulmonic valve and a peak right ventricular systolic pressure of 100 mm Hg...

Cirrhotic cardiomyopathy is associated with poor outcomes in patients with cirrhosis. We investigated if subclinical cardiac morphologic and functional modifications can influence survival in cirrhotic patients during follow-up. A series of cirrhotic patients without cardiovascular or pulmonary disease underwent standard and tissue Doppler echocardiography to assess left ventricular (LV) geometry, systo/diastolic function and the main haemodynamic parameters. After baseline evaluation 115 cirrhotic patients were followed up for at least 6 years...

A 2-year-old male intact Belgian Malinois was presented for exercise intolerance. A grade III/VI left basilar systolic murmur was detected. Echocardiography revealed moderate right atrial and ventricular dilation and increased pulmonic outflow velocity. Thoracic radiographs showed right heart enlargement and a dilated caudal vena cava. In addition, on the left lateral projection, an enlarged aberrant right cranial pulmonary lobar vein was suspected to be diverging ventrally from the course of the right cranial lobar bronchus and inserting more ventrally than normal in the region of the right atrium...

BACKGROUND: The 2015 American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations for chamber quantification suggest new abnormality threshold and severity partition values for left atrial (LA) volume that are equally valid for the biplane method of disk (MOD) summation and the area-length method (ALM). However, they have never been clinically validated. Thus, we compared the clinical and prognostic impact of LA volume assessed by MOD and ALM by using both the 2015 and 2005 abnormality thresholds...

A 54-year-old man presented at our facility with a 3-month history of exertional breathlessness and purple blotches around his eyes. Examination revealed bilateral periorbital and perioral ecchymosis, purpuric spots along his waist, and waxy papules on his eyelids. In addition, the patient had macroglossia with nodular infiltration and irregular indentations at the lateral margin of his tongue. The patient also had a raised jugular venous pressure and prominent atrial and ventricular waves. Further examination revealed a fourth heart sound over the left ventricular apex, as well as bilateral basal rales...

BACKGROUND: Among patients with ischemic stroke and atrial fibrillation, which ones are at high risk of recurrent stroke is unclear. This study aimed to determine whether left atrial size was associated with long-term risk of stroke recurrence in patients with nonvalvular atrial fibrillation. METHODS AND RESULTS: In this multicenter prospective cohort study, nonvalvular atrial fibrillation patients hospitalized for acute ischemic stroke were enrolled and followed up after discharge...

The purpose of this research was to compare the accuracy of newly described P wave-related parameters (P wave area, Macrux index and mean electrical axis) with classical P wave-related parameters (voltage and duration of P wave) for the assessment of left atrial (LA) size in dogs with degenerative mitral valve disease. One hundred forty-six dogs (37 healthy control dogs and 109 dogs with degenerative mitral valve disease) were prospectively studied. Two-dimensional echocardiography examinations and a 6-lead ECG were performed prospectively in all dogs...

BACKGROUND: Radiofrequency catheter ablation (CA) is an effective treatment of drug-refractory atrial fibrillation (AF). However, the efficacy of CA by race and gender has not been well characterized. We sought to determine the impact of ethnicity and gender on clinical outcome following CA in patients with AF. METHODS: Patients who underwent CA for AF from September 2013 to April 2016 were included in this study. Patients were identified retrospectively and followed prospectively...

BACKGROUND: Percutaneous atrial septal defect (ASD) closure is a routine procedure to prevent right ventricular failure, pulmonary hypertension, or paradoxical embolism. The latter is the typical reason for percutaneous patent foramen ovale (PFO) closure. Atrial enlargement represents a risk for developing atrial fibrillation (AF). Percutaneous left atrial appendage (LAA) closure is emerging as a preventive therapy for patients in AF who suffered from a previous stroke or bleeding (secondary prevention) or patients without previous stroke or bleeding (primary prevention)...

Left atrial enlargement has been shown to be associated with obstructive sleep apnea in patients with coronary artery disease and in sleep clinic cohorts. However, data from the general population are limited. The aim of this study was to investigate whether there is an association between obstructive sleep apnea and left atrial enlargement in a random sample from a general population of 71-year-old men. As part of the longitudinal population study The Study of Men Born in 1943, we analysed cross-sectional data for 411 men, all 71 years old, who had participated in an overnight home sleep study and a standardized echocardiographic examination...

Backround: Left atrial (LA) enlargement plays an important role in the development of heart failure (HF) and is a robust prognostic factor. Fibrotic processes have also been advocated to evoke HF through finite signalling proteins. METHODS: We examined the association of two such proteins, cystatin C (CysC) and galectin-3 (Gal-3), and other clinical, echocardiographic and biochemical parameters with LA volume index (LAVi) in patients with HF with severely impaired left ventricular ejection fraction (LVEF)...

OBJECTIVES: Predictive models for heart failure (HF) in heterogeneous populations have had limited success. We examined cardiac computed tomography angiography (CTA) predictors of HF or cardiovascular death (HF-CVD) in a prospective study of asymptomatic diabetics undergoing baseline assessment by CTA. METHODS: The subjects (n = 735, aged 55-74 years, 51.2% women) had no clinical history of cardiovascular disease at study entry. Coronary artery calcium (CAC) score, CTA-defined coronary atherosclerosis, cardiac chamber volumes, and clinical data were collected and late outcome events recorded over 8...

We report on a family in which initial features were compatible with Fryns syndrome. The first sibling was a stillborn female with a left diaphragmatic hernia (DH). Her clinical features overlapped with Fryns syndrome. The second pregnancy, a male fetus, was followed for polyhydramnios, hypoplastic mandible, mild enlargement of the fetal bladder, hydronephrosis, and rocker bottom foot deformities. He had facial features similar to his sibling and a large cleft of the secondary palate, small jaw, and secundum atrial septal defect...

We report the first trimester three-dimensional ultrasonographic findings in a 13-week-old fetus with complex phenotype and a de novo 4.7 Mb multigene deletion encompassing chromosome region 20q13.13-q13.2 detected by chromosomal microarray. Fetal sonography detected radial-ray anomalies in the form of bilateral absence of thumbs and the left club hand deformity. The presence of single atrioventricular canal instead of the atrial septal defect typical for Holt-Oram syndrome pointed us to rather suspect the SALL4 related diseases...

An approximately two-year-old, male 6.1 kg body weight, Korean wild raccoon dog (Nyctereutes procyonoides koreensis) was captured by the wildlife medical rescue center of Kangwon National University. Upon physical examination, the heart rate was 87 beats per min and there were no clinical signs. The hematological, and blood biochemical profiles revealed no remarkable findings; however, thoracic radiographs showed cardiac enlargement, especially in the right atrium. On electrocardiogram, sinus node dysfunction and bradyarrhythmia were revealed...

BACKGROUND: The P wave on an ECG is a measure of atrial electric function, and its characteristics may serve as predictors for atrial arrhythmias. Increased mean P-wave duration and P-wave terminal force traditionally have been used as markers for left atrial enlargement, and both have been associated with increased risk of atrial fibrillation. Here, we explore the genetic basis of P-wave morphology through meta-analysis of genome-wide association study results for P-wave duration and P-wave terminal force from 12 cohort studies...

Left ventricular dysfunction increases left atrial pressures and causes atrial remodeling. In human subjects, increased left atrial size is a powerful predictor of mortality and adverse events in a broad range of cardiac pathologic conditions. Moreover, structural remodeling of the atrium plays an important role in the pathogenesis of atrial tachyarrhythmias. Despite the potential value of the atrium in assessment of functional endpoints in myocardial disease, atrial pathologic alterations in mouse models of left ventricular disease have not been systematically investigated...
