Echocardiography is commonly performed as a screening test to evaluate perioperative risks before kidney transplantation. However, only limited data are available on echocardiographic parameters of left ventricular diastolic dysfunction (LVDD) and left atrial enlargement (LAE) on acute coronary syndrome and mortality in kidney transplant recipients. We reviewed 2779 adult recipients who underwent pretransplant echocardiography from 1997 to 2012. We divided the patients into two and four groups by two categories: LVDD grades 0-1 vs...

INTRODUCTION: Cor triatriatum is a congenital cardiac anomaly in which the left (sinister) or right (dexter) atrium is divided into two compartments by residual embryonic tissue, resulting in a tri-atrial heart. As cor triatriatum dextrum can present clinically in various ways and have multiple associated cardiac anomalies, this report attempts to contribute to what is known about this exceedingly rare disorder. CASE: A 40 year old Hispanic man with a medical history of gastritis presented with complaints of palpitations, dizziness and bilateral lower extremity edema...

BACKGROUND: Obstructive sleep apnea (OSA) has been associated with worse diastolic function in patients with coronary artery disease (CAD). This analysis determined whether continuous positive airway pressure (CPAP) treatment would improve diastolic function in CAD patients with nonsleepy OSA. METHODS: Between December 2005 and November 2010, 244 revascularized CAD patients with nonsleepy OSA (apnea-hypopnea index (AHI) ≥15/h, Epworth Sleepiness Scale [ESS] score<10) were randomly assigned to CPAP or no-CPAP...

Aims: Right atrial (RA) fibrillation (RAF) was previously characterized by initiation from RA ectopies, presence of a right-to-left dominant frequency gradient during atrial fibrillation (AF), and augmentation of the gradient by adenosine triphosphate infusion. We investigated structural characteristics of the bi-atria and epicardial adipose tissue (EAT) volume in patients with RAF. Methods and results: By using multidetector computed tomography, RA, left atrial (LA), right and LA appendage (RAA and LAA, respectively) volumes, pulmonary vein (PV) sizes, and EAT volumes were compared between the RAF group (n = 8) and LA fibrillation (LAF) group (n = 32)...

BACKGROUND: Previous studies have suggested PITX2, KCNN3 and ZFHX3 as atrial fibrillation (AF) susceptibility genes. Single common genetic polymorphisms of those genes have been linked with AF phenotypes and rhythm outcome of AF catheter ablation although their mechanisms remain elusive. New gene-based association tests may help clarifying genotype-phenotype correlations. Therefore, we hypothesized that PITX2, KCNN3 and ZFHX3 associate with left atrial enlargement and persistent AF and subsequently with ablation outcome...

BACKGROUND: Left atrial (LA) sphericity can predict recurrence of atrial fibrillation (AF) after radiofrequency catheter ablation (RFCA). We sought to reconfirm the prognostic role of atrial sphericity after RFCA of AF, assess any relationship between the atrial pressure and sphericity, and determine the characteristics of the patients for whom atrial sphericity was most highly predictive. METHODS: All 148 non-valvular AF patients (57±11 years, 121 men, 95 paroxysmal AF [PaAF]) who underwent RFCA were enrolled...

The main mechanism of the CHADS2 and CHA2DS2-VASc scores to predict stroke in nonvalvular atrial fibrillation (NVAF) is still controversial. We evaluated the association of the CHADS2 and CHA2DS2-VASc scores with left atrial thrombus (LAT) as detected by transesophageal echocardiographic (TEE) and compared the predictive ability of these risk stratification schemes with nonvalvular atrial fibrillation (NVAF). Data from 2,695 consecutive NVAF patients in whom TEE was performed for screening LAT from July 2007 to February 2014 were analyzed...

BACKGROUND: Impaired relaxation filling pattern in the presence of preserved left ventricular ejection fraction is a common finding which is ascribed to early diastolic dysfunction. We thought to determine the distribution of various markers of systolic and diastolic dysfunction in these patients. METHODS: A total of 106 patients were included in this retrospective observational study. Diastolic dysfunction was defined using the American Society of Echocardiography recommendations ("50% rule")...

OBJECTIVE: To assess the incidence, possible risk factors and prognosis of pulmonary arterial hypertension (PAH) in critically ill elderly patients. METHODS: We selected 122 cases admitted to the ICU, ages 60-93 years old. An echocardiography examination was performed within four days after admission to the ICU. PAH is usually suspected if the patient's pulmonary artery systolic pressure ≥ 40 mmHg. We collected echocardiography data, relevant clinical data and routine laboratory data; we then used a statistical method to analyze the risk factors for PAH in critically ill elderly patients and examined its impact on the prognosis...

We report the successful primary anatomic correction of an atrioventricular septal defect with transposition of the great arteries and pulmonary stenosis in a 4-year-old girl with left isomerism by common atrioventricular valve division, Mustard-type atrial septation, and a Rastelli operation with ventricular septal defect enlargement. To the best of our knowledge, this is the first report of total correction for this combination of cardiac anomalies.

BACKGROUND: To investigate the left atrial (LA) size as an independent predictor of mortality following coronary artery bypass surgery (CABG). METHODS: This single center study evaluated determinants of mortality in 1070 patients who underwent isolated CABG from 2005-2014. Clinical, laboratory and demographic data were obtained from medical records. Collinearity between enlarged LA size (diameter ≥ 4 cm) and covariates was identified. The adjusted effects of enlarged LA size on 30-day mortality post CABG were tested using multiple logistic regression models...

An 87-year-old man with persistent atrial fibrillation experienced heartburn and dysphagia at 2 years 9 months after initiation of dabigatran. An esophagogastroduodenoscopy demonstrated multiple longitudinal white plaques with ulcers in the narrowed midesophagus compressed between the left atrium and the tortuous aorta. We speculate that the esophageal stenosis contributed to stasis of dabigatran within the esophagus, resulting in prolonged mucosal contact with the caustic contents of the drug. Progressive enlargement of the left atrium may have led to the late onset of the potentially serious complication...

OBJECTIVES: This is an early feasibility clinical test of mitral loop cerclage annuloplasty to treat secondary mitral valve regurgitation. BACKGROUND: Secondary mitral regurgitation is characterized by cardiomyopathy, mitral annular enlargement, and leaflet traction contributing to malcoaptation. Transcatheter mitral loop cerclage applies circumferential compression to the mitral annulus by creating a loop through the coronary sinus across the interventricular septum, protecting entrapped coronary arteries from compression, and interactive annular reduction under echocardiographic guidance...

Aims: Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome with various phenotypes and outcomes. The prognostic relevance of echocardiography and the E/e' ratio has previously been reported. We sought to study in addition, the value of estimated pulmonary pressure and left atrial size for diagnosing and determining a prognosis for HFpEF-patients in a prospective multi-centric cohort. Methods and results: Patients with an acute-HF event accompanied with NT-proBNP >300 pg/mL (BNP >100 pg/mL) and LVEF >45% were included (n = 237) and clinically reassessed using echo-Doppler after 4-8 weeks of HF treatment as part of the prospective KaRen HFpEF study...

BACKGROUND: While left atrial (LA) enlargement is known as an early sign of left heart disease with prognostic implications in heart failure (HF), the importance of right atrial (RA) enlargement is less well studied, and the prognostic implications of interatrial size comparison are insufficiently understood. The aim of this study was to test the hypothesis that RA area larger than LA area in apical four-chamber view is associated with all-cause mortality in elderly patients with HF independent of left ventricular ejection fraction (LVEF)...
