Incidence, Predictors, and Outcome Associations of Dyskalemia in Heart Failure With Preserved, Mid-Range, and Reduced Ejection Fraction.

JACC Heart Fail 2018 Dec 10. Epub 2018 Dec 10.

Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden.

Objectives: This study investigated 1-year incidence and predictors of dyskalemia (dysK) and its outcome associations in heart failure with preserved ejection fraction (HFpEF), HF with mid-range EF (HFmrEF), and HF with reduced EF (HFrEF).

Background: DysK in real-world HF is insufficiently characterized. Fear of dyskalemia may lead to underuse or underdosing of renin-angiotensin-aldosterone system inhibitors. Read More

Heart Failure and Liver Disease: Cardiohepatic Interactions.

JACC Heart Fail 2018 Dec 7. Epub 2018 Dec 7.

Department of Cardiology, Larissa University General Hospital, Larissa, Greece. Electronic address:

Heart failure (HF) and liver disease often co-exist. This is because systemic disorders and diseases affect both organs (alcohol abuse, drugs, inflammation, autoimmunity, infections) and because of complex cardiohepatic interactions. The latter, which are the focus of this review, include the development of acute cardiogenic liver injury and congestive hepatopathy in HF as well as cardiac dysfunction and failure in the setting of liver cirrhosis, nonalcoholic fatty liver disease, and sequelae following liver transplantation.

Iron Deficiency in Heart Failure: An Overview.

JACC Heart Fail 2018 Dec 7. Epub 2018 Dec 7.

Division of Cardiology and Metabolism-Heart Failure, Cachexia and Sarcopenia, Department of Cardiology, Campus Virchow-Klinikum, Charité-Universitätsmedizin Berlin, Berlin, Germany; Berlin-Brandenburg Center for Regenerative Therapies, Charité-Universitätsmedizin Berlin, Berlin, Germany.

Iron deficiency is an extremely common co-morbidity in patients with heart failure, affecting up to 50% of all ambulatory patients. It is associated with reduced exercise capacity and physical well-being and reduced quality of life. Cutoff values have been identified for diagnosing iron deficiency in heart failure with reduced ejection fraction as serum ferritin, <100 μg/l, or ferritin, 100 to 300 μg/l, with transferrin saturation of <20%.

JACC Heart Fail 2018 Dec 10. Epub 2018 Dec 10.

Department of Internal Medicine, Division of Cardiology, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, New York.

Advanced imaging modalities provide essential anatomic and spatial information in patients with complex heart disease. Two-dimensional imaging can be limited in the extent to which true 3-dimensional (3D) relationships are represented. The application of 3D printing technology has increased the creation of physical models that overcomes the limitations of a 2D screen. Read More

Proportionate and Disproportionate Functional Mitral Regurgitation: A New Conceptual Framework That Reconciles the Results of the MITRA-FR and COAPT Trials.

JACC Cardiovasc Imaging 2018 Dec 6. Epub 2018 Dec 6.

Division of Cardiology, Department of Internal Medicine, Baylor University Medical Center, Dallas, Texas.

Traditional approaches to the characterization of secondary or functional mitral regurgitation (MR) have largely ignored the critical importance of the left ventricle (LV). We propose that patients with secondary MR represent a heterogenous group, which can be usefully subdivided based on understanding that the effective regurgitant orifice area (EROA) is dependent on left ventricular end-diastolic volume (LVEDV). According to the Gorlin hydraulic orifice equation, patients with heart failure, an LV ejection fraction of 30%, an LVEDV of 220 to 250 ml, and a regurgitant fraction of 50% would be expected to have an EROA of ≈0.

Histopathologic Characterization of Peripheral Arteries in Subjects With Abundant Risk Factors: Correlating Imaging With Pathology.

JACC Cardiovasc Imaging 2018 Dec 6. Epub 2018 Dec 6.

CVPath Institute, Gaithersburg, Maryland.

Objectives: The aim of this study was to comprehensively evaluate the pathology of the lower extremity arteries across their entire length in subjects dying with abundant risk factors and to evaluate the clinical and imaging implications of the pathological characteristics.

Background: Lower extremity peripheral arterial disease is a major cause of cardiovascular morbidity, but a systematic characterization of the pathology has never been undertaken.

Methods: Twelve legs were obtained from 8 cadavers with histories of coronary risk factors (median age 82 years, 6 men); 8 of 12 legs were evaluated using computed tomography before the major peripheral arteries were dissected along their entire length. Read More

Columbia University Medical Center/NewYork Presbyterian Hospital, New York, New York.

Objectives: This study presents a single-site experience of 5 patients with severe tricuspid regurgitation (TR) who underwent implantation of a novel transcatheter tricuspid valve replacement device.

Background: Functional TR is the most common etiology of severe TR in the developed world and is associated with unfavorable clinical outcomes. Although numerous transcatheter repair devices are currently in early clinical trials, most result in incomplete degrees of TR reduction and functional improvement. Read More
