Exercise behavior of degenerative mitral stenosis.

Int J Cardiovasc Imaging 2020 May 26. Epub 2020 May 26.

Heart and Vascular Institute, Einstein Medical Center, Philadelphia, PA, USA.

Mitral annular calcification (MAC) is increasingly encountered, particularly among the elderly and those with chronic kidney disease, and is often associated with a transvalvular gradient. In contrast to rheumatic mitral stenosis relatively little is known about mitral stenosis due to MAC. We aimed to clarify whether exercise limitation in this group is primarily due to valvular obstruction or ventricular dysfunction resulting from multiple comorbidities. Read More

Surg Technol Int 2020 May;36:217-223

Department of Cardiovascular Surgery, Mount Sinai Medical Center, Icahn School of Medicine at Mount Sinai, New York, New York.

Severe tricuspid regurgitation (TR) is associated with significant mortality and morbidities. Currently, surgical tricuspid repair with annuloplasty is the gold standard treatment. However, the prohibitive risks of open surgery and increasing evidence that severe TR should be intervened on early has led to an outburst in the development and evolution of transcatheter tricuspid valve interventions (TTVI).

Medical decision making for 5D cardiac model: Template matching technique and simulation of the fifth dimension.

Comput Methods Programs Biomed 2020 Jul 7;191:105382. Epub 2020 Feb 7.

COSMOS Laboratory -National Institute of Computer Sciences (ENSI), University of Mannouba, Tunisia. Electronic address:

The purpose of this paper is to develop a 5D cardiac model which is inspired from the 5D model for the lungs. This model depends on five variables: the anatomical structure of the 3D heart, temporal dimension and the function of blood flow as the fifth dimension. To test this hypothesis, we took the same mathematical modeling as a reference for the fifth dimension of pulmonary flow where r→(t)=r→(t)+r→(t) wherer→(t) is the displacement vectors with approximate magnitudes by linear functions of the tidal volume and r→(t) is the blood flow.

Right ventricular outflow tract diseases are historically outcomes of surgical reconstruction for heart defects in neonates or children (Tetralogy of Fallot, Ross surgery). This kind of surgery performed during childhood lead often to dysfunctional right ventricular outflow tract (stenosis, leak) in older infants or young adults. In this case, reintervention on the right ventricular outflow tract would be associated with a high surgical risk. Read More

UNIVERSITY OF LOUISVILLE, LOUISVILLE, KENTUCKY.

Anomalous origin of the right coronary artery (ARCA) is an extremely rare cardiac pathology. The coronary artery can potentially course between the aorta and the pulmonary artery, putting the patient at risk for sudden cardiac death. Even rarer is an ARCA that arises from the left main coronary artery (LMCA). Read More

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.

Left Ventricular Morphology and Function as a Determinant of Pulmonary Hypertension in Patients with Severe Aortic Stenosis: Cardiovascular Magnetic Resonance Imaging Study.

Medicina (Kaunas) 2019 Oct 22;55(10). Epub 2019 Oct 22.

Department of Cardiology, Medical Academy, Lithuanian University of Health Sciences, LT 44307 Kaunas, Lithuania.

The influence of cardiac magnetic resonance (CMR) derived left ventricular (LV) parameters on the prognosis of patients with aortic stenosis (AS) was analyzed in several studies. However, the data on the relations between the LV parameters and the development of pulmonary hypertension (PH) in severe AS is lacking. Our objectives were to evaluate the CMR-derived changes of the LV size, morphology, and function in patients with isolated severe AS and PH, and to investigate the prognostic impact of these parameters on elevated systolic pulmonary artery pressure (sPAP).

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.

Carcinoid Heart Disease: A Guide for Clinicians.

Cardiol Clin 2019 Nov;37(4):497-503

Division of Cardiology, Department of Medicine, University of Michigan, 1500 East Medical Center Drive, Ann Arbor, MI 48109, USA. Electronic address:

Carcinoid heart disease is the collective term for all cardiac manifestations that develop in patients with carcinoid. The cardiac manifestations of carcinoid tumors are attributed to the paraneoplastic effects of vasoactive substances released by the malignant cells. The clinical manifestations of carcinoid heart disease include valvular destruction leading to valvular regurgitation and stenosis, right-sided heart failure, and metastatic carcinoid disease.

Novel ELN mutation in a Japanese family with a severe form of supravalvular aortic stenosis.

Mol Genet Genomic Med 2019 11 27;7(11):e986. Epub 2019 Sep 27.

Life Science Center for Survival Dynamics, Tsukuba Advanced Research Alliance (TARA), University of Tsukuba, Tsukuba, Japan.

Background: Supravalvular aortic stenosis (SVAS) is one of the congenital cardiovascular diseases characterized by stenosis of the aorta. The stenotic lesions occur anywhere above the aortic valve in the aortic tree as well as pulmonary arteries and eventually leads to circulatory failure. The disease gene has been identified on the elastin gene (ELN) and two types of SVAS have been categorized; a familial type and an isolated type with the de novo mutation. Read More
