F-Sodium Fluoride (F-NaF) for Imaging Microcalcification Activity in the Cardiovascular System.

Arterioscler Thromb Vasc Biol 2020 Jul 7;40(7):1620-1626. Epub 2020 May 7.

From the BHF Centre for Cardiovascular Science, University of Edinburgh, United Kingdom.

Accumulating preclinical and clinical evidence suggests that calcification is one of the body's primary responses to injury and a key pathological feature of cardiovascular disease. Calcification activity can now be imaged using F-sodium fluoride (F-NaF) positron emission tomography (PET) in combination with either computed tomography or magnetic resonance. These techniques allow visualization of calcification activity and, therefore, provide different information to the established macroscopic calcium imaged with computed tomography. Read More

Background: Global left atrial strain (LA) has been used as a novel assessment tool to evaluate left atrial function. However, not much has been investigated to study the effect of percutaneous balloon mitral valvotomy (BMV) in patients with rheumatic severe mitral stenosis on global LA strain. We studied the relationship between global left atrial (LA) strain and severe mitral stenosis and the effect of BMV on LA strain. Read More

Frequency and Clinical Associating Factors of Valvular Heart Disease in Asymptomatic Korean Adults.

Sci Rep 2019 11 14;9(1):16741. Epub 2019 Nov 14.

Division of Cardiology, Department of Medicine, Cardiovascular Imaging Center, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.

Limited information is available on the prevalence and clinical determinants of valvular heart disease (VHD) in apparently healthy people. This study sought to assess the frequency and clinical associating factors of aortic stenosis (AS), aortic regurgitation (AR), mitral stenosis (MS), mitral regurgitation (MR), tricuspid regurgitation (TR) in asymptomatic individuals with health check-up examination. We included 23,254 subjects ≥50 years of age who underwent a health check-up examination with transthoracic echocardiography (TTE) between 2012 and 2016 in a single tertiary-care hospital in Korea.

Staging Cardiac Damage in Patients With Hypertension.

Hypertension 2019 12 4;74(6):1357-1365. Epub 2019 Nov 4.

Cardiovascular Center, Tazuke Kofukai Medical Research Institute, Kitano Hospital, Osaka, Japan (Y.M., Y.Y., Y.H., E.N., T.H., M.I.).

Ventricular and extraventricular response to pressure overload may be a common process in aortic stenosis and hypertension. We aimed to evaluate the association of a newly defined staging classification characterizing the extent of cardiac damage, originally developed for aortic stenosis, with long-term outcomes in patients with hypertension. We retrospectively analyzed 1639 patients with hypertension who had undergone both scheduled transthoracic echocardiography and electrocardiography in 2013 in a Japanese hospital, after excluding severe and moderate aortic stenosis, aortic regurgitation, mitral stenosis, previous myocardial infarction, or cardiomyopathy.

The role of stress echocardiography in cardiovascular disorders.

Kardiol Pol 2019 Nov 24;77(11):1011-1019. Epub 2019 Oct 24.

Institute of Family Medicine, University of Szeged, Szeged, Hungary

Stress echocardiography is a safe, low‑cost, widely available, radiation‑free versatile imaging modality that is becoming increasingly recognized as a valuable tool in the assessment of coronary heart disease. In recent years, there has also been an increasing use of stress echocardiography in the assessment of nonischemic cardiac disease given its unique ability for simultaneous assessment of both functional performance and exercise‑related noninvasive hemodynamic changes, which can help guide treatment and inform about the prognosis of the patients. Today, in the echocardiography laboratory, we can not only detect wall motion abnormalities resulting from coronary artery stenosis, but also detect alterations to the coronary microvessels, left ventricular systolic and diastolic parameters, heart valves, pulmonary circulation, alveolar‑capillary barrier, and right ventricle.

Oblique coronary artery prolongation in anomalous left coronary artery arising from the pulmonary artery: A case series.

J Card Surg 2019 Dec 22;34(12):1434-1438. Epub 2019 Oct 22.

Section of Cardiothoracic Surgery, St Christopher's Hospital for Children, Philadelphia, Pennsylvania.

Background: Anomalous left coronary artery (LMCA) arising from the pulmonary artery (ALCAPA) is a life-threatening congenital birth defect. Prompt surgical correction by reimplantation of the LMCA into the aorta is the treatment of choice, however, unfavorable LCA location or length can make direct reimplantation difficult or even impossible without causing significant stretching or tension on the LMCA. This tension can lead to stenosis of the artery and coronary ischemia and must be avoided if possible. Read More

Caseous Calcification of the Mitral Annulus: A Role for Surgery.

Ann Thorac Surg 2020 Jun 10;109(6):e441-e444. Epub 2019 Oct 10.

Service of Cardiac Surgery, Institut de cardiologie et de pneumologie de Québec (IUCPQ)-Université Laval, Quebec City, Quebec, Canada. Electronic address:

An 80-year-old man followed for aortic stenosis was found to have an intracardiac mass. Multiple imaging modalities were inconclusive in characterizing the mass but raised concerns about the potential malignancy of the mass. Fear of operating on an elderly patient with a potential for cardiac neoplasia led to a percutaneous transseptal biopsy that failed to provide a clear diagnosis. Read More
