Rheologic genesis of discrete subvalvular aortic stenosis: A Doppler echocardiographic study [PDF]

open access: yes, 1992
To determine whether morphologic structures or abnormal flow patterns predispose to pathologic proliferation or subvalvular tissue, 26 patients (mean age 19.8 ± 10.3 years) were studied ≥6 months after operation for isolated discrete subvalvular aortic ...

A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging [PDF]

open access: yesarXiv, 2015
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure.

Obstruction of left ventricular outflow tract by a calcified mass at mitral valve [PDF]

open access: yesMedicinski Glasnik, 2010
A case of an unusual left ventricular outflow tract obstruction by mitral valve pathology in a 35-year old female with diabetes and end-stage renal disease is presented in the study.

A One Health Approach to Hypertrophic Cardiomyopathy. [PDF]

open access: yes, 2017
Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiac disease in humans and results in significant morbidity and mortality. Research over the past 25 years has contributed enormous insight into this inherited disease particularly in the ...

Ventricular torsional relation to ventricular fiber arrangement [PDF]

open access: yesarXiv, 2014
Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole.

Identifying logarithmic tracts [PDF]

open access: yesarXiv, 2019
We show that a direct tract bounded by a simple curve is a logarithmic tract and further give sufficient conditions for a direct tract to contain logarithmic tracts. As an application of these results, an example of a function with infinitely many direct singularities, but no logarithmic singularity over any finite value, is shown to be in the Eremenko-

Vector Field Streamline Clustering Framework for Brain Fiber Tract Segmentation [PDF]

open access: yesarXiv, 2020
Brain fiber tracts are widely used in studying brain diseases, which may lead to a better understanding of how disease affects the brain. The segmentation of brain fiber tracts assumed enormous importance in disease analysis. In this paper, we propose a novel vector field streamline clustering framework for brain fiber tract segmentations.

Left ventricular outflow tract obstruction by accessory mitral tissue. A review regarding a case.

open access: yesRevista Cubana de Cardiología y Cirugía Cardiovascular, 2011
The presence of accessory mitral valve tissue is a rare congenital abnormality that rarely,causes left ventricular outflow tract obstruction. Its presentation in adults is uncommon.

Systems Analysis Implicates WAVE2 Complex in the Pathogenesis of Developmental Left-Sided Obstructive Heart Defects. [PDF]

open access: yes, 2020
Genetic variants are the primary driver of congenital heart disease (CHD) pathogenesis. However, our ability to identify causative variants is limited.
