BACKGROUND: Nowadays there is an increased interest in the role of aortic stiffness in the pathophysiology of heart failure (HF), since it is a major determinant of left ventricular (LV) performance. We aimed at assessing the predictive value of the aortic stiffness parameters, measured by echocardiography, in patients affected by non-ischemic dilated cardiomyopathy (DCM) regarding three end-points: death, HF rehospitalization, combined death or HF rehospitalization in a long-term follow-up...

BACKGROUND: Functional mitral regurgitation (MR) caused by reduced left ventricular ejection fraction (EF) and tethering, termed ventricular functional MR (VFMR), is associated with worse outcomes. Atrial functional MR (AFMR) caused by left atrial enlargement and annular dilatation was also recently described in patients with atrial fibrillation (AF). However, the clinical profiles of AFMR in hospitalized heart failure (HF) patients are unclear. We investigated the prevalence, clinical characteristics, and prognosis of AFMR in hospitalized HF patients with AF...

RATIONALE: Inadvertent pacemaker/defibrillator lead placement into the left ventricle is an unusual cardiac device-related complication and its diagnosis is not always easy and often misunderstood. Thromboembolic events are frequently associated with this procedural complication. Percutaneous lead extraction should be performed when diagnosis is made early after device implantation while long-life oral anticoagulation is a wise option when the diagnosis is delayed and the lead is not removed...

Left ventricular thrombi are mostly seen in the akinetic segments of left ventricle and warfarin is the golden standard treatment. In our case, a 67-year-old male patient with ischemic dilated cardiomyopathy and atrial fibrillation was under warfarin treatment, but due to fluctuations in international normalized ratio, warfarin was discontinued and changed to rivaroxaban (20 mg once a day). He had a fixed thrombus measuring 1.80 × 1.12 cm2 in the left ventricle under warfarin treatment before rivaroxaban use...

A 3-year-old castrated male domestic shorthair presented to the Cornell University Hospital for Animals for acute onset respiratory distress. Thoracic radiographs, echocardiogram, and electrocardiogram (ECG) revealed left-sided congestive heart failure, myocardial thickening with left atrial dilation, and sinus rhythm conducted with a left bundle branch block, respectively. Cardiac troponin I was elevated and continued to increase over 36 h (1.9 ng/mL, 3.1 ng/mL, and 3.5 ng/mL, sequentially every 12 h)...

Cancer patients may experience nonvalvular atrial fibrillation (AF) as a manifestation of cardiotoxicity. AF may be a direct effect of a neoplasm or, more often, appear as a postsurgical complication, especially after thoracic surgery. AF may also develop as a consequence of anticancer therapy (chemotherapy or radiotherapy), a condition probably underestimated. Cancer patients with AF require a multidisciplinary approach involving oncologists/hematologists, cardiologists, and coagulation experts. An echocardiogram should be performed to detect possible abnormalities of left ventricular systolic and diastolic function, as well as left atrial dilation and the existence of valvular heart disease, to determine pretest probability of sinus rhythm restoration, and identify the best treatment...

BACKGROUND/AIMS: MicroRNAs (miRNAs) can be used as biomarkers for cardiovascular diseases, especially for heart failure. However, there are few reports on serum exosomal miRNA biomarkers in patients with acute heart failure (AHF) due to Dilated cardiomyopathy (DCM). METHODS: We analyzed 3 different serum exosomal miRNAs (exo-miR-92b-5p, exo-miR-192-5p, and exo-miR-320a) in 43 patients with DCM-AHF and 34 healthy volunteers as a control group (CG) by using exosome separation followed by a quantitative reverse-transcript PCR assay...

Atrial fibrillation (AF) often complicates the course of inherited cardiomyopathies and, in some cases, may be the presenting feature. Each inherited cardiomyopathy has its own peculiar pathogenetic characteristics that can contribute to the development and maintenance of AF. Atrial fibrillation may occur as a consequence of disease-specific defects, non-specific cardiac chamber changes secondary to the primary illness, or a combination thereof. The presence of AF can denote a turning point in the progression of the disease, promoting clinical deterioration and increasing morbidity and mortality...

Arrhythmic risk stratification in idiopathic dilated cardiomyopathy (IDC) remains a major concern. As the ventricles remodel in time, risk factors for arrhythmic death may change. A cohort of 710 patients with idiopathic dilated cardiomyopathy, without previous ventricular arrhythmias, was retrospectively studied to understand how risks vary in time. The primary end point was a composite of sudden cardiac death, ventricular fibrillation, sustained ventricular tachycardia, and appropriate implantable cardioverter-defibrillator interventions...

BACKGROUND: Atrial remodeling, vagal tone and atrial ectopic triggers have been suggested to contribute to the increased incidence of atrial fibrillation (AF) in endurance athletes. How these parameters change with increased lifetime training hours is debated. HYPOTHESIS: We hypothesised that atrial remodeling occurs in proportion to total training history, thus contributing to the elevated risk of AF. METHODS: We recruited 99 recreational endurance athletes, subsequently grouped according to lifetime training hours, to undergo evaluation of atrial size, autonomic modulation and atrial ectopy...

Aims: The need for right ventricular assist device (RVAD) support after left ventricular assist device (LVAD) therapy is associated with increased morbidity and mortality. We used 2D echocardiographic strain analysis to assess right atrial (RA) and right ventricular (RV) mechanics and predict the need for RV mechanical support after LVAD implantation. Methods and results: Seventy advanced chronic heart failure (ACHF) patients [59 male, age 47 ± 12 years, 79% dilated cardiomyopathy, left ventricular ejection fraction 23 ± 10%] received continuous-flow LVAD as a bridge to transplantation over an 18 month period...

BACKGROUND: Left atrial decompression is considered in patients with symptomatic heart failure with preserved ejection fraction (HFpEF). We aimed to evaluate the feasibility and efficacy of transcatheter generation of a restrictive atrial septum communication to manage HFpEF from infancy to adulthood with cardiomyopathy and congenital heart defect. METHODS AND RESULTS: From June 2009 to December 2016, 24 patients (50% with an age less than 16 years) with HFpEF were palliated; NYHA-/Ross class IV (n = 10); median systemic ventricular ejection fraction 64 (range 35-78) %...

PURPOSE: Hypertrophic cardiomyopathy (HCM) impairs left ventricular (LV) diastolic function leading to left atrial (LA) dilatation. Because Doppler echocardiography cannot accurately assess LV diastolic function in hearts with heterogeneous hypertrophy, assessment of LA function might be useful for risk stratification of patients with HCM. This study aimed to elucidate the impact of LA function on outcome in patients with patients. METHODS: Seventy-six patients with HCM who underwent echocardiographic and cardiac magnetic resonance imaging were retrospectively enrolled...

Mitral stenosis (MS) is prevalent in 0.02-0.2% of the population in developed countries. The pathophysiology of MS results in elevated left atrial pressures and over-time results in pulmonary hypertension (HTN) which ultimately affects the right ventricle. In addition, MS restricts the diastolic filling of the left ventricle. Therefore, during induction patients with MS are limited by their ability to increase cardiac output by increasing stroke volume. Anesthesia goals in severe MS are to avoid sudden changes in heart rate, as well as systemic and pulmonary artery pressures...

BACKGROUND: Left atrial (LA) volume is a predictor of outcome in hypertension. It is unclear whether or not this effect depends on coexisting target organ damage (TOD). PURPOSE: To investigate whether LA volume predicts outcome independently of TOD [left ventricular (LV) hypertrophy (LVH) and/or carotid plaque] in a registry of hypertensive treated patients. METHODS: From the Campania Salute Network registry, we selected 5844 young adult hypertensive patients <65 years old (mean age 50 ± 9 years, 41% women, 8% diabetic) without prevalent CV or valvular heart disease more than mild, with normal LV ejection fraction, stage III or less CKD and available follow-up...
